Abstract

A polyol composition comprising a solid polyol which is crystalline under normal conditions and, as an anti-caking agent therefor, a tertiary amine containing at least two identical organic substituents, each having two to twenty carbon atoms. A method of preventing caking of polyols is disclosed wherein to such polyols there is added at least one of such tertiary amines, preferably in a concentration of 0.05 to 0.25 percent by weight based on the weight of the polyol.
