Abstract
A method of producing, at an improved reaction rate, acyl lactylate salts, such as sodium stearoyl-2-lactylate, calcium stearoyl-2-lactylate and mixtures thereof, which involves the addition of from about 2% to about 30% (by weight of final salt composition) of substantially fully hydrogenated stearin comprising at least 50% (by weight of fatty acid) C.sub.18 fatty acid and having an iodine value of less than about 7. The intermediate reaction charge is also disclosed.
Claims22
A method for producing an acyl lactylate salt which includes:
- (a) an esterification reaction step occurring after an intial charge of a lactylic acid and an acyl fatty acid, and
- (b) the incorporation of from about 2% to about 30% of stearin prior to completion of said esterification step;
- (c) said stearin containing at least about 50% (by weight of fatty acid) C.sub.18 fatty acid.
An intermediate charge for use in the production of acyl lactylate salt comprising:
- (a) a major portion of a lactylic acid,
- (b) a major portion of an acyl fatty acid, and
- (c) about 2% to about 30% of stearin containing at least about 50% (by weight of fatty acid) C.sub.18 fatty acid.
