ISO/TR 19838 discusses cosmetics microbiology. ISO/TR 19838 gives general guidelines to explain the use of ISO cosmetic microbiological standards depending on the objective (in-market control, product development, etc.) and the product to be tested.
ISO/TR 19838 can be used to fulfill the requirements of the ISO standard on microbiological limits (ISO 17516).
ISO/TR 19838 on cosmetics microbiology is useful for:
Every cosmetic manufacturer has a dual responsibility relative to the microbiological quality of its products. The first is to ensure that the product, as purchased, is free from the numbers and types of microorganisms that could affect product quality and consumer health. The second is to ensure that microorganisms introduced during normal product use will not adversely affect the quality or safety of the product.
ISO/TR 19838 gives you the guidance of international standards that help you in the estimation number of viable aerobic mesophilic microorganisms (bacteria, yeasts and moulds) within a cosmetic which is called microbial content. ISO/TR 19838 guides you with antimicrobial preservation and gives you examples of microbial content results. ISO/TR 19838 helps you to ensure the safety of your cosmetic products and maintain their quality.
