PEG-23M

Safety grade: A

PEG-23M is a thick, waxy polymer derived from petroleum that acts like a glue in cosmetic products. It helps keep all the different ingredients mixed together smoothly and controls how thick or thin the product feels.

This ingredient binds product components together, prevents separation of oil and water, and adjusts the product's thickness to create the desired texture and consistency.
