PEG-90M

Safety grade: A

PEG-90M is a thick, waxy synthetic polymer that acts like a glue and thickener in cosmetic products. It helps keep different ingredients mixed together and gives products a stable, creamy consistency.

This ingredient binds product components together, prevents separation of oil and water-based ingredients, and controls how thick or thin the product feels.

Graded using: COSING.
