Glycereth-7 Trimethyl Ether

Glycereth-7 trimethyl ether is a synthetic compound derived from glycerin and trimethyl ether. Its role in skin care and other personal care products is to serve as both an emollient and a humectant to enhance skin moisturization (ability to stay supple) and hydration (ability to retain water). It can also function as a solvent.

Although independent studies have yet to be conducted, suppliers of glycereth-7 trimethyl ether highlight its remarkable ability to impart a silky, emollient touch to the skin, leaving a subtly dry finish.

Glycereth-7 trimethyl ether’s impressive stability across a wide pH spectrum is touted as particularly advantageous in formulations containing salicylic acid (BHA), enhancing overall formulary compatibility. Additionally, in carbomer-based gels, it effectively mitigates tackiness, contributing to a more pleasant sensory experience.

In its raw material state, glycereth-7 trimethyl ether presents as a transparent, light-yellow liquid. Suggested use level of this ingredient is 5–6%.

At the time of this writing, the Cosmetic Ingredient Review Expert Panel has not conducted a formal safety assessment of glycereth-7 trimethyl ether. Currently there is no evidence suggesting any safety concerns associated with its use in cosmetic products.
