Claim Text:
1. A process of preparing a hydroxy functional animal fat, the process comprising: (A) adding raw animal fat and optionally a vegetable oil, to an organic acid or peracid in a reactor to form mixture; (B) heating the mixture to about 50-150° C. with agitation generating a hot mixture; (C) adding 25 to 70% w/w of hydrogen peroxide/water to the hot mixture of (B) generating a reaction mixture; (D) heating the reaction mixture in a range of 50-150° C. for about 1 to 168 hours; (E) stripping off the bulk of the organic acid, water and other low boilers at or below a stripping temperature of 170° C. at a negative pressure that does not exceed 60 mmHg, until the reaction mixture tests for an acid number of about 10 mg KOH/g or less, creating the hydroxyl functional animal fat.
