Preservative System Testing in Cosmetic Lotions
The use of preservatives and antimicrobial agents in cosmetic lotions is a critical aspect of ensuring product safety, stability, and shelf-life. Preservatives are designed to inhibit the growth of microorganisms such as bacteria, fungi, and yeasts that can contaminate products during manufacturing or storage. This service focuses on evaluating the efficacy of preservative systems used in cosmetic lotions through rigorous testing methods compliant with international standards.
Preservative testing involves a series of procedures aimed at determining the optimal level of preservatives required to prevent contamination while ensuring consumer safety. The key factors considered include the type, concentration, and compatibility of preservatives within the formulation. The testing process typically follows these steps:
- Sample Preparation: Cosmetics are prepared for analysis by removing any packaging materials and thoroughly mixing the contents.
- Microbiological Challenges: Samples are inoculated with various microorganisms to simulate real-world contamination scenarios.
- Incubation Periods <|im_start|><|im_start|>⚗
