Frequently Asked Questions
What is sodium isostearoyl lactylate used for?
Sodium isostearoyl lactylate (CAS 52558-73-3) is used as an anionic emulsifier and conditioning/texturizing agent in cosmetic and personal-care formulations, and as a stabilizer for oil-in-water emulsions. RawSource supplies it as a raw material to formulators.
What is sodium isostearoyl lactylate made from?
It is the sodium salt of the isostearic acid ester of lactic acid (formula C17H33NO3). The combination of a fatty-acid and lactic-acid backbone gives it its emulsifying and conditioning behavior. Refer to the SDS and technical data sheet for specifications.
Is sodium isostearoyl lactylate the same as sodium lauryl sulfate?
No. It is a lactylate-class anionic emulsifier derived from isostearic and lactic acids, not a sulfate detergent. The two have different chemistries, CAS numbers, and formulation roles, so they are not interchangeable.
How does it compare to sodium stearoyl lactylate and sodium lauroyl lactylate?
All three are lactylate emulsifiers differing in the fatty-acid chain — isostearoyl (branched C18), stearoyl (straight C18), and lauroyl (C12). The chain length and branching affect HLB, melting behavior, and skin feel, so formulators select the grade matching their emulsion. Specify the exact CAS when ordering.
How is bulk sodium isostearoyl lactylate packaged and quoted?
It is supplied as cosmetic-grade material in drums or other bulk packaging suitable for emulsifier handling. Provide your target quantity to receive a bulk quote with a Certificate of Analysis and SDS.
