Disclosed herein is a novel 2,3-dialkoxypropyl glyceryl ether and the preparation process for it. The above diglycerin dialkyl ether is readily prepared with high yield and purity by reacting its corresponding glycidyl ether with a protected glycerin to form a 1,3-dioxolan compound, followed by etherifying the thus formed 1,3-dioxolan compound into a dialkyl ether dioxolan compound, and then hydrolyzing the resultant dialkyl ether dioxolan compound. This diglycerin dialkyl ether is useful as an emulsifier, cleaner etc., and is preferably used as a component of cosmetic compositions. A cosmetic composition comprising the above 2,3- dialkoxypropyl glyceryl ether is also disclosed.
