Cosmetic Cosmetic testing is essential for verifying the safety, quality, performance, and regulatory compliance of cosmetic and personal care products before they are placed on the market.
Bilim Laboratories provides comprehensive ISO/IEC 17025 accredited cosmetic testing services using internationally recognized analytical methods to support manufacturers, brand owners, importers, and regulatory compliance processes.
Our cosmetic testing services include microbiological, chemical, physical, stability, and preservative efficacy evaluations for a wide range of cosmetic products.
Microbiological testing verifies the microbiological quality of cosmetic products and helps ensure consumer safety throughout the product’s shelf life.
Our laboratory performs testing for microbial contamination, including bacteria, yeasts, and moulds, particularly for water-based cosmetic products such as creams, lotions, shampoos, gels, and liquid soaps.
Chemical analysis confirms product composition and regulatory compliance by determining the presence of restricted or prohibited substances and verifying ingredient specifications.
Our testing capabilities include analyses for:
Physical testing evaluates the quality characteristics of cosmetic products, including:
Stability testing evaluates whether cosmetic products maintain their quality, safety, and performance throughout their intended shelf life under defined storage conditions.
These studies also assess product compatibility with its packaging and verify that product performance remains unchanged over time.
The Challenge Test (Preservative Efficacy Test) evaluates the effectiveness of the preservative system in cosmetic and personal care products against microbiological contamination during normal consumer use.
This study demonstrates whether the preservative system can effectively inhibit the growth of microorganisms throughout the product’s intended shelf life after opening, in accordance with internationally accepted testing protocols.
