POLYESTER-14

Safety grade: A

Polyester-14 is a lightweight synthetic polymer that acts like a microscopic sponge in cosmetic formulations. It helps keep all the different ingredients in a product mixed together smoothly instead of separating.

This ingredient stabilizes emulsions (preventing oil and water from separating) while also softening and conditioning the skin with a smooth, comfortable feel.

Graded using: COSING.
