Compatibility of Preservatives (Alcohol) with Prebio-care and the Need for Preservation
Question
I am formulating a cosmetic product containing Prebio-care.
- Will using cosmetic preservatives, especially alcohol, in the formulation negatively impact the effectiveness of Prebio-care on the skin by killing the beneficial bacteria it supports?
- Can Prebio-care function as a preservative for the formulation itself?
- Is it necessary to use a separate preservative in a formulation containing Prebio-care?
Answer
Using cosmetic preservatives, including alcohol, in a formulation does not negatively impact the effectiveness of Prebio-care on the skin. Cosmetic preservatives are designed to control microbial growth within the product itself and their activity is limited to the product. They do not continue to exert significant antimicrobial effects on the skin after application, which is where Prebio-care functions to promote beneficial bacteria.
Prebio-care is a prebiotic ingredient that feeds beneficial bacteria and does not act as a preservative for the product. It is essential to use a suitable preservative in your formulation to prevent spoilage and microbial contamination, even when using Prebio-care. Mild preservatives like Mild Preserved Eco are an option.
