ABSTRACT OF THE DISCLOSURE A polyol composition comprises 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 dis- closed wherein there is added to such polyols at least one such tertiary amine, preferably in a concentration of 0.05 to 0.25 percent by weight based on the weight of the polyol. The polyol composition exhibits improved anti- caking properties and storability.
