POLYESTER-6

Safety grade: A

This is a synthetic polymer, similar to plastic, that is created in a laboratory. It helps mix together ingredients that normally don't blend well, like oil and water.

It acts as an emulsifier to keep oil and water-based ingredients mixed together smoothly in cosmetic products, preventing them from separating.

Graded using: COSING.
