Setting New Benchmarks in Cosmetics with Peptide Testing

Peptides are transforming the cosmetics industry, offering advanced solutions for skin repair, hydration, and anti-aging. As these bioactive compounds gain popularity, ensuring their safety and effectiveness has become a top priority. 

Cotecna, a global leader in cosmetic testing, inspection, and certification, is emphasizing the critical role of peptide testing in cosmetics. With consumers demanding transparency and regulators tightening standards, peptide analysis is essential to validate product claims and safeguard public health. 

Why Peptide Testing is Essential 

• Safety First: Testing ensures peptides are free from harmful contaminants and allergens.
• Proven Efficacy: Laboratory analysis confirms peptides deliver on their promises, such as stimulating collagen or reducing wrinkles.
• Regulatory Compliance: Thorough testing supports compliance with EU and international cosmetic regulations.
• Consumer Confidence: Verified claims strengthen trust between brands and consumers. 

Cotecna provides comprehensive testing and certification services to support cosmetic manufacturers worldwide. By combining advanced analytical techniques with regulatory expertise, Cotecna helps ensure that peptide-based products meet the highest standards of safety and performance. 

Neotron Peptide Testing Capabilities 

Neotron offers comprehensive peptide testing to ensure the safety and prove the efficacy of these ingredients in cosmetics. Companies can rely on our capabilities to ensure the quality of their ingredients which contribute to safe and good quality cosmetics. 

1. Safety First: Neotron can: 

• Detect residual impurities, like solvents, or ubiquitous contaminants, like heavy Metals and PFAS, or degradation by-products, like nitrosamines. Testing these impurities can help Safety Assessors evaluate their effective toxicological concerns and their impact on finished products, if impurities are present. At the same time, tests can confirm the purity of the ingredients if these impurities are absent.
• Perform microbiological testing according to the internationally recognized ISO standards to assure the microbiological purity of the ingredients.
• Perform Chemical Characterization: to ensure the good quality of the ingredients, Neotron can determine the amino acids composition of peptides and quantify the total amino acids through acid hydrolysis and detection by HPLC-DAD. Moreover, Neotron can measure the molecular weight of the peptides, to give precise information of their penetration and bioavailability to Safety Assessors, ensuring they comply with the provision of Cosmetic Regulations. 

2. Proven Efficacy: Neotron can offer specific and customized In Vivo and In Vitro efficacy tests, based on the claims cosmetic companies would like to prove and claim for their finished products. In Vitro tests can show the action mechanism of the peptides, both as a single ingredient and inside a finished cosmetic product. Meanwhile, In Vivo tests can support claims such as “promoting the reduction of the wrinkles, stimulating the production of collagen and elastin, increasing skin tone and elasticity” and so on.

3. Regulatory Compliance: our Safety Assessors can direct cosmetic companies to the best analytical plans to prove safety and efficacy and advise on restrictions, limits and prohibition of these ingredients in finished cosmetic products. 

4. Consumer Confidence: All these steps help guarantee public trust in the brands. However, Neotron goes a step further and offers consumer tests which help cosmetic companies to investigate consumer preferences, analyze their suggestions, compare the products with other brand products, test the pleasantness and assure product success on the market!  

With Cotecna’s global expertise and Neotron’s laboratory capabilities, the industry can ensure that peptide-based products meet the highest standards of safety, efficacy, and consumer satisfaction. Together, Cotecna and Neotron are setting a new benchmark for cosmetic safety and innovation, helping brands deliver products that consumers can trust.
