Cosmetic Ingredients ( Part 2: Preservatives )

Cosmetic products can become easily contaminated by microbes because they contain water, oils, peptides, and carbohydrates which creates a very good medium for growth of microbes.

All these factors contribute to the fact that cosmetic products need very good preservation to prevent microbial growth and spoiling of the cosmetic product and also infection of the skin. Preservatives are active ingredients able to prevent the growth bacteria, fungi, & viruses.

Examples of Preservatives in Cosmetics:

- Benzylalcohol-DHA
- Caprylyl Glycol EHG
- EDTA
- Grapefruit Seed Extract
- Paraben EU
- Potassium Sorbate
