Before, During or After Formulation?"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">Absolutely. I\u2019ll keep the <strong>Makrolife posts in English<\/strong> and make the readability a priority: short paragraphs, varied sentence openings, plenty of transition words, clear H2 structure, and a natural focus keyphrase.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">When Should You Test a New Product? Before, During or After Formulation?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Developing a new product involves more than creating a good formula.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Testing also needs to happen at the right time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many companies wait until the formulation is finished before they contact a laboratory. That can work for some tests. However, it can also create unnecessary delays when a problem is discovered late in development.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A better approach is to treat testing as part of the <strong>product development process<\/strong>, rather than as the final step before launch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So when should you actually test a new product?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The answer depends on what you need to learn.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Testing should start before the formula is finished<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Testing does not always mean sending the final product to a laboratory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Early in development, testing can help answer important questions about:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>raw materials<\/li>\n\n\n\n<li>active ingredients<\/li>\n\n\n\n<li>contaminants<\/li>\n\n\n\n<li>compatibility<\/li>\n\n\n\n<li>microbiological risks<\/li>\n\n\n\n<li>product performance<\/li>\n\n\n\n<li>regulatory requirements<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This information can influence the formulation before it becomes difficult or expensive to change.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a manufacturer may discover that a planned ingredient has an impurity issue. If that happens early, the formulation can be adjusted before stability studies, packaging decisions and regulatory documentation are finalised.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is much easier than discovering the same issue after the product has already been prepared for launch.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Stage 1: Test the raw materials<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Before testing the finished product, it can be useful to understand the materials going into it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product, relevant checks may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>identity<\/li>\n\n\n\n<li>purity<\/li>\n\n\n\n<li>microbiological quality<\/li>\n\n\n\n<li>heavy metals<\/li>\n\n\n\n<li>residual solvents<\/li>\n\n\n\n<li>contaminants<\/li>\n\n\n\n<li>active ingredient content<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The exact testing programme depends on the ingredient and intended use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A supplier&#8217;s Certificate of Analysis can provide valuable information. However, it does not automatically replace independent testing or a risk-based assessment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Makrolife supports analytical testing across areas including food, supplements, pharmaceuticals, cosmetics, medical devices and food-contact materials. <a href=\"https:\/\/www.makrolife-biotech.com\/en\/sicherheitsbewertungen?utm_source=chatgpt.com\">Makrolife Biotech<\/a><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Why raw material testing matters<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">A finished product can only be as controlled as its inputs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose an ingredient specification allows a certain impurity level.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That impurity may then carry into the finished formulation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you identify the issue before formulation, there are more options available.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You could:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>change the supplier<\/li>\n\n\n\n<li>request a tighter specification<\/li>\n\n\n\n<li>select a different raw material<\/li>\n\n\n\n<li>adjust the formulation<\/li>\n\n\n\n<li>introduce an additional purification step<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Once the final product is already manufactured, those options become much more expensive.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Stage 2: Test during formulation<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Testing can also take place while the formula is still being developed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At this stage, the goal is often not regulatory approval.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead, testing helps answer:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Does the formulation behave as expected?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product, this could involve:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>pH<\/li>\n\n\n\n<li>viscosity<\/li>\n\n\n\n<li>active ingredient concentration<\/li>\n\n\n\n<li>microbiological quality<\/li>\n\n\n\n<li>compatibility<\/li>\n\n\n\n<li>physical stability<\/li>\n\n\n\n<li>preservative effectiveness<\/li>\n\n\n\n<li>performance testing<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This information can guide formulation decisions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a result, the laboratory becomes part of the development process rather than simply a final checkpoint.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">A small formulation change can have a big effect<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Changing one ingredient can affect several parts of a product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, changing:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the preservative<\/li>\n\n\n\n<li>fragrance<\/li>\n\n\n\n<li>emulsifier<\/li>\n\n\n\n<li>active ingredient<\/li>\n\n\n\n<li>solvent<\/li>\n\n\n\n<li>pH<\/li>\n\n\n\n<li>packaging<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">can alter stability or microbiological behaviour.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, a formula that looks almost identical on paper may still require additional testing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The earlier that change is identified, the easier it is to evaluate.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Stage 3: Test the prototype<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Once the formulation is sufficiently developed, prototype testing becomes more meaningful.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At this point, you can start asking whether the product is likely to meet its intended specifications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product category, this may include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Analytical testing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Does the product contain the expected amount of the active or relevant ingredients?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Microbiological testing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Does it meet the required microbiological quality?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Stability testing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Does the product remain within specification over time?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Safety-related testing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Are there specific risks that need to be investigated?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Performance testing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Does the product actually deliver the intended function?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The testing programme should be linked to the product&#8217;s risks and intended claims.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Stage 4: Stability testing<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Stability testing should not be treated as something that happens only after every other decision has been made.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For many products, stability data can influence:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>shelf life<\/li>\n\n\n\n<li>storage conditions<\/li>\n\n\n\n<li>packaging<\/li>\n\n\n\n<li>formulation<\/li>\n\n\n\n<li>product specifications<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For cosmetics, for example, Makrolife provides accelerated stability and compatibility testing to support shelf-life assessment and product documentation. <a href=\"https:\/\/www.makrolife-biotech.com\/sicherheitsbewertungen?utm_source=chatgpt.com\">Makrolife Biotech<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Starting stability work too late can therefore delay the entire launch.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Why stability testing takes time<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Some product decisions simply cannot be accelerated indefinitely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A stability study needs sufficient time to observe how the product changes under defined conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product, researchers may monitor:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>appearance<\/li>\n\n\n\n<li>odour<\/li>\n\n\n\n<li>pH<\/li>\n\n\n\n<li>viscosity<\/li>\n\n\n\n<li>active content<\/li>\n\n\n\n<li>microbiological quality<\/li>\n\n\n\n<li>packaging compatibility<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If a company waits until the planned launch date is approaching, there may not be enough time to generate the required data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why stability testing belongs in the development timeline.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Stage 5: Test the final formulation<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Once the formulation is frozen, final testing becomes important.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The objective now changes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You are no longer asking:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u201cCan we improve this formula?\u201d<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead, you are asking:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u201cDoes this final product meet its defined requirements?\u201d<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product, final testing can support:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>specifications<\/li>\n\n\n\n<li>quality control<\/li>\n\n\n\n<li>safety assessments<\/li>\n\n\n\n<li>regulatory documentation<\/li>\n\n\n\n<li>product release<\/li>\n\n\n\n<li>claims<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This is where the analytical data become part of the final evidence package.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Cosmetics are a good example<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">For cosmetics placed on the EU market, the safety assessment needs to consider the final product and relevant supporting information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Cosmetic Product Safety Report is required before a cosmetic product is placed on the EU market under Regulation (EC) No 1223\/2009. [European Commission, <em>Cosmetic Products<\/em>, <a href=\"https:\/\/single-market-economy.ec.europa.eu\/sectors\/cosmetics\/cosmetic-products_en]\">https:\/\/single-market-economy.ec.europa.eu\/sectors\/cosmetics\/cosmetic-products_en]<\/a> <a href=\"https:\/\/www.makrolife-biotech.com\/en\/sicherheitsbewertungen?utm_source=chatgpt.com\">Makrolife Biotech<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The supporting evidence can include information about the formulation, toxicology, microbiology and stability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Consequently, testing should not be treated as a completely separate activity from regulatory preparation.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Food and supplements need a different approach<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Food products and supplements have their own testing priorities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product, testing may focus on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>nutritional composition<\/li>\n\n\n\n<li>active ingredients<\/li>\n\n\n\n<li>contaminants<\/li>\n\n\n\n<li>microbiological quality<\/li>\n\n\n\n<li>allergens<\/li>\n\n\n\n<li>heavy metals<\/li>\n\n\n\n<li>pesticide residues<\/li>\n\n\n\n<li>stability<\/li>\n\n\n\n<li>product specifications<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The exact programme depends on the product, ingredients and intended market.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Makrolife specifically provides testing and studies for food and supplements, including analyses of ingredients, purity and specifications. <a href=\"https:\/\/www.makrolife-biotech.com\/healthcare-marketing?utm_source=chatgpt.com\">Makrolife Biotech<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the testing strategy should be defined around the product rather than copied from another category.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Testing too early can also be inefficient<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">There is an important balance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Testing everything at every stage is not a good strategy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An early prototype may change several times.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you perform a full final-product testing programme on every prototype, costs can increase without generating useful long-term data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead, testing should follow the development stage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Early stage:<\/strong> answer development questions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Middle stage:<\/strong> identify risks and optimise the formulation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Final stage:<\/strong> generate evidence for specifications, safety and compliance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is a more efficient approach.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">A risk-based testing plan works better<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">There is no universal testing checklist that fits every product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A face cream, dietary supplement and medical device have completely different risk profiles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the testing plan should consider:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>product category<\/li>\n\n\n\n<li>intended use<\/li>\n\n\n\n<li>ingredients<\/li>\n\n\n\n<li>target population<\/li>\n\n\n\n<li>exposure<\/li>\n\n\n\n<li>manufacturing process<\/li>\n\n\n\n<li>packaging<\/li>\n\n\n\n<li>claims<\/li>\n\n\n\n<li>applicable regulations<\/li>\n\n\n\n<li>intended market<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Once these factors are clear, the required tests become easier to identify.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">What happens if you wait until the end?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Imagine a company develops a product for six months.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The formula is final.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The packaging is selected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The marketing materials are ready.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then laboratory testing identifies a stability problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The formula needs to change.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now the company may need to reconsider:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>packaging<\/li>\n\n\n\n<li>stability studies<\/li>\n\n\n\n<li>safety documentation<\/li>\n\n\n\n<li>specifications<\/li>\n\n\n\n<li>labels<\/li>\n\n\n\n<li>claims<\/li>\n\n\n\n<li>launch timing<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The original delay was not caused by the laboratory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It was caused by <strong>testing being introduced too late<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Testing should follow the product development timeline<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">A practical development timeline can look like this:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Concept<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p

class=\"wp-block-paragraph\"><strong>Launch<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The exact sequence can change.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the principle remains the same:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Testing should provide information when that information can still influence a decision.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">What should you test before formulation?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Before the formula is fixed, focus on information that can influence the design.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product, that may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>raw material purity<\/li>\n\n\n\n<li>contaminant risks<\/li>\n\n\n\n<li>active ingredient identity<\/li>\n\n\n\n<li>regulatory restrictions<\/li>\n\n\n\n<li>microbiological risks<\/li>\n\n\n\n<li>compatibility questions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This stage is about <strong>reducing uncertainty<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">What should you test during formulation?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">During formulation, the questions become more specific.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You may want to know:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Is the active stable?<\/li>\n\n\n\n<li>Does the preservative system work?<\/li>\n\n\n\n<li>Is the formulation microbiologically controlled?<\/li>\n\n\n\n<li>Does the pH remain suitable?<\/li>\n\n\n\n<li>Are ingredients compatible?<\/li>\n\n\n\n<li>Does the product maintain its intended characteristics?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These tests help the R&amp;D team make better formulation decisions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">What should you test after formulation?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Once the formula is frozen, the focus shifts toward verification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product, that can include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>final product specifications<\/li>\n\n\n\n<li>stability<\/li>\n\n\n\n<li>microbiology<\/li>\n\n\n\n<li>active

class=\"wp-block-paragraph\">At this point, the results are much more likely to become part of the final technical and regulatory documentation.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Testing and regulatory work should be connected<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">A common mistake is to treat laboratory testing and regulatory compliance as two separate projects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They are closely connected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A regulatory requirement can determine what needs to be tested.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The resulting analytical data can then support the regulatory assessment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Makrolife combines laboratory analysis with regulatory and compliance services, including technical documentation, conformity assessments and market-access support. <a

process more efficient.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Your testing plan should answer four questions<\/h1>\n\n\n\n<p

What decision will this test support?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If there is no clear decision, the test may not be necessary yet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. What stage is the product in?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A prototype does not always need the same testing as a final product.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. What regulatory requirement applies?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The intended market and product category can change the testing requirements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. What happens if the result fails?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A failed test is much easier to manage when there is still time to reformulate or change the process.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">The goal is not to test everything<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">More testing does not automatically mean better product development.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The goal is to generate <strong>relevant, reliable evidence at the right time<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That means testing should be:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>risk-based<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>purpose-driven<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>appropriate to the product<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and <strong>connected to the development timeline<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach can reduce unnecessary testing while still protecting product quality and compliance.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">When should you test a new product?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The short answer is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Before, during and after formulation.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The tests simply serve different purposes at each stage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Before formulation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Understand the raw materials, risks and regulatory constraints.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">During formulation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use testing to guide development and identify problems early.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">After formulation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Verify the final product and generate evidence for quality, safety and compliance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Waiting until the final product is ready is often too late.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">The Makrolife approach<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Makrolife supports product development with analytical testing, validation, regulatory consulting and safety assessments across several industries, including healthcare, medical devices, cosmetics, food and nutrition. <a href=\"https:\/\/www.makrolife-biotech.com\/en?utm_source=chatgpt.com\">Makrolife Biotech<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The advantage of connecting these services is straightforward:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>testing can be planned around the actual product development and regulatory pathway.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of asking a laboratory to test a finished product without context, companies can define what information they need at each stage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That makes the results more useful for R&amp;D, quality and regulatory teams.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">The bottom line<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Testing should not be the final hurdle before a product launch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It should be part of the development strategy from the beginning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Early testing can identify raw-material and formulation risks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Testing during development can guide formulation decisions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Final testing can verify the finished product and support regulatory documentation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The best time to test is therefore not simply <strong>\u201cafter formulation.\u201d<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is <strong>whenever the result can still help you make a better decision<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a new product, that usually means starting early, testing selectively and increasing the level of verification as the formulation moves toward launch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When should you test a new product?
