Full Description

Sodium stearoyl lactylate (CAS 25383-99-7) is the sodium salt of the stearic-acid ester of lactic acid, an anionic emulsifier. PubChem and JECFA classify it as a food emulsifier, and CIR lists it as a cosmetic emulsifying agent. It emulsifies and stabilizes food systems such as baked goods and serves as an emulsifier in personal-care formulations.

Frequently Asked Questions

What is sodium stearoyl lactylate made from?

It is the sodium salt of the stearic-acid ester of lactic acid (CAS 25383-99-7), an anionic emulsifier built from stearic acid and lactic acid. The feedstock origin (plant or animal stearic acid) varies by grade, so confirm on the CoA. RawSource supplies it for food and personal-care formulation use.

Is sodium stearoyl lactylate a dairy product?

No. Despite the lactic-acid component, lactic acid here is produced industrially and is not derived from milk, so the material itself is not a dairy product. For any specific allergen or sourcing requirement, confirm the origin statement on the CoA. RawSource can provide grade documentation on request.

What is sodium stearoyl lactylate used for?

PubChem and JECFA classify it as a food emulsifier, and it is used as an emulsifying and stabilizing agent in baked goods and processed foods, particularly bread and bakery dough systems. CIR also lists it as a cosmetic emulsifying agent. RawSource supplies food- and cosmetic-grade material in bulk; specify which grade you need.

What grades of sodium stearoyl lactylate are available?

It is supplied in food-grade and cosmetic-grade forms; the applicable grade and any food-additive specification are stated on the CoA and are not interchangeable across uses. Tell us your application (bakery, processed food, or personal care) when requesting a quote. RawSource will confirm the matching grade.

What bulk packaging and documentation does RawSource provide for sodium stearoyl lactylate?

It ships to manufacturers in bags, drums, or totes matched to grade and order volume, with a CoA and SDS on every order. Request a quote with your target quantity and required grade for delivered pricing.
