Quick Answer

Cosmetic Testing for dietary supplements involves analyzing product samples using validated scientific methods to verify safety, purity, potency, and regulatory compliance. Accredited labs like Qalitex use instrumentation such as HPLC, ICP-MS, and microbiology assays to generate Certificates of Analysis (COA) required by FDA, Amazon, and retail partners.

Dietary supplements brands require specialized testing to ensure product safety, regulatory compliance, and consumer trust. Qalitex Laboratories provides cosmetic testing specifically designed for the dietary supplements industry. At Qalitex Laboratories, we offer comprehensive cosmetic and beauty product testing services designed to help skincare, makeup, and beauty brands ensure product safety, regulatory compliance, and performance. We specialize in cosmetic microbiology, stability, compatibility, preservative efficacy, and claims substantiation. Our testing protocols are calibrated to the unique requirements of dietary supplements products, from raw material verification to finished goods release testing.

Cosmetic Testing Tailored for Dietary supplements

The dietary supplements industry has specific testing requirements driven by FDA regulations, marketplace compliance (Amazon, retail), and consumer safety expectations. Qalitex designs testing panels specifically for dietary supplements products, ensuring you meet all applicable standards while optimizing your testing budget. Our scientists understand the unique matrices and formulation challenges of dietary supplements products.

Why Cosmetic Testing Matters

Regulatory compliance ensures your product meets FDA and international regulations. Our testing validates that formulations are free of microbial contaminants and allergens, confirms stability over time, supports marketing claims with lab-backed data, and satisfies retailer requirements for Amazon, Target, Sephora, and other major retailers.

Microbiology Testing for Cosmetics

We perform total aerobic microbial count (TAMC), yeast and mold count, and pathogen detection (E. coli, S. aureus, P. aeruginosa) for cosmetic and personal care formulations. Our challenge testing (PET) verifies the effectiveness of your preservative system per USP <51> and ISO 11930.

Stability & Shelf Life Studies

Real-time and accelerated stability testing evaluates appearance, viscosity, pH, color, fragrance, and active ingredient stability over time. We test all cosmetic formats including creams, serums, oils, gels, and powders under ICH-equivalent conditions.
