PEG-16

Safety grade: A

PEG-16 is a lightweight, clear liquid made from petroleum-derived materials that acts like a moisture magnet and helper ingredient in cosmetics. It pulls water into the skin and helps dissolve other ingredients so they mix together smoothly.

This ingredient helps cosmetic products retain moisture and feel smooth on the skin, while also allowing other active ingredients to dissolve evenly throughout the product.

Graded using: COSING.
