DEFINITION

Classification: 525/517.5

Mixed with a reactant which is a fatty acid glycerol ester, a fatty acid or salt derived from a naturally occurring glyceride, tall oil, or a fatty acid derived from tall oil; or the reaction product of any of the above with a polycarboxylic acid or ester forming derivative and a polyhydroxy compound:

(under subclass 509) Subject matter wherein a reactant which is a fatty acid glyceride, a fatty acid derived from a naturally occurring glyceride, tall oil, or a fatty oil or salt thereof or a reaction product of any of these materials with a polycarboxylic acid or ester and a polyol.

(1) Note. The so-called oil modified alkyl resins are treated herein in the same manner as fatty glycerides or the fatty acid derived therefrom.

(2) Note. Dehydrated castor oil fatty acids are included herein.

(3) Note. See Lines With Other Classes and Within This Class, section II. B(6) for a discussion of the lines between this subclass and other areas.
