PEG-20M

Safety grade: A

PEG-20M is a synthetic polymer (a chain-like molecule) that acts like a thickener and stabilizer in cosmetic products. It helps keep creams and lotions from separating and improves their texture and consistency.

This ingredient thickens products, helps bind ingredients together, and prevents emulsions from breaking down, ensuring cosmetics stay smooth and stable on the shelf and when used.
