Abstract
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 18 fatty acid and having an iodine value of less than about 7. The intermediate reaction charge is also disclosed.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
66 words
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 18 fatty acid.
Claim 2
Independent Claim
66 words
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 18 fatty acid.
