PEG-45

Safety grade: A

PEG-45 is a thick, gel-like substance made from petroleum that acts like a glue in cosmetic products. It helps keep products moist and allows different ingredients to mix together smoothly.

This ingredient binds product components together, draws moisture into the skin to keep it hydrated, and helps dissolve other ingredients so they work effectively in the formula.

Graded using: COSING.
