What Is Bis-PEG-18 Methyl Ether Dimethyl Silane?
Bis-PEG-18 methyl ether dimethyl silane is a synthetic wax-like ingredient belonging to the chemical class of siloxanes and silicones. In cosmetics, it serves multiple purposes, including skin conditioning agent, surfactant, foam booster, and moisturizer. Claims that silicones in any form cause or worsen skin concerns have not been substantiated in any published research, nor have reports that silicones are sensitizing to or somehow “suffocate” skin. In fact, just the opposite is true which makes the misinformation difficult to understand. Almost all the claims about silicones being problematic for skin are either myths or based on anecdotal evidence. Bottom line: The types of silicones used in cosmetic products are supported by scientific research and are considered safe for consumer use. These types of cosmetic silicones are effective, inert, and versatile ingredients that benefit skin and hair in numerous ways.
