Glycerine derivatives represented by formula (1A), (2A) and (3A):
wherein R1a, R2a, R1b, R2b, R1c, and R2c are as defined in the disclosure, and process for producing glycerin derivatives, including the glycerin derivatives (1A), (2A) and (3A), are disclosed. The glycerin derivatives have satisfactory physical properties and are applicable as lubricants or polar oils and also have mutual effects with water and are applicable as emulsifying agents or moisture retaining agents. The process makes it possible to synthesize glycerin derivatives from easily and economically available aldehydes or ketones in high yields.

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.
