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.
