Preservatives – Keeping our cosmetics safe & fresh
Why do we need preservatives in cosmetics? Our cosmetics can spoil or grow bacteria, fungi, and yeasts, without the assistance of preservatives, our cosmetics could become harmful.
Microorganisms grow readily in water, and most cosmetic products contain water as the largest or one of the largest ingredients. Additionally, the nutrients, vitamins, and many of the active ingredients in cosmetics can make excellent microorganism food. Thus, providing a prime environment to fuel their growth.
The issue preservatives solve is contamination. Most people don’t think of their hands as contaminates, but our hands contain microorganisms and are not sterile. So, every time we put our fingers into a jar of lotion or push the pump on a lotion bottle we are introducing new microorganisms into our products that can quickly cause spoilage, or worse, without preservatives.
