Frequently Asked Questions

What is sodium lauroyl lactylate used for?

Sodium lauroyl lactylate (CAS 13557-75-0) is an anionic emulsifier and conditioning surfactant used in personal-care formulations and as an emulsifier and texture aid in food processing. RawSource supplies it as a raw material; specify food or cosmetic grade on your inquiry.

Is sodium lauroyl lactylate the same as sodium lauryl sulfate?

No. Sodium lauroyl lactylate is a lactylate-class emulsifier — the sodium salt of the lauric acid ester of lactic acid (C18H31NaO6) — not a sulfate detergent. Despite the similar-sounding name, the chemistry, CAS, and function differ, so they are not interchangeable.

What is sodium lauroyl lactylate made from?

It is produced from lauric acid (a C12 fatty acid, often coconut/palm-derived) esterified with lactic acid and neutralized to the sodium salt. This fatty-acid/lactic-acid backbone gives it its emulsifying and conditioning behavior. See the technical data sheet for grade specifications.

How does it compare to sodium stearoyl lactylate?

Both are lactylate emulsifiers; the difference is the fatty acid — lauroyl (C12) versus stearoyl (C18). Chain length affects HLB, melting point, and emulsion feel, so formulators pick the grade that matches their oil-in-water system. Specify the exact CAS when ordering.

How is bulk sodium lauroyl lactylate packaged and quoted?

It is supplied in drums or other bulk packaging suitable for emulsifier handling, in food or cosmetic grade. Provide your required grade and quantity to receive a bulk quote with a Certificate of Analysis and SDS.
