PURPOSE:To prevent the hydrolysis of an acetal or ketal linkage and thereby obtain a glycerin deriv. compsn. having an improved stability by adding an nonionic surfactant to a glycerin deriv. or a mixture of two or more glycerin derivs. CONSTITUTION:A glycerin deriv. compsn. having an improved stability and useful for a plasticizer, various additives, a solvent, etc., is obtd. by adding a nonionic surfactant of formula III (wherein R is 8-36C alkyl or alkenyl; AO is 2-4C oxyalkylene; and a is an integer of 1-30) to a glycerin deriv. (an acetal or ketal) or a mixture of two or more glycerin derivs. represented by formula I or II (wherein R to R are each H, 1-4C alkyl, or 2-4C alkenyl). The amt. of the surfactant added, though variable with its application, is pref. 0.1-30 pts.wt. based on 100 pts.wt. the deriv.; for diluting with a solvent, the concn. of 0.5wt.% or higher is pref.
