Sodium isostearoyl lactylate

Sodium Isostearoyl Lactylate (CAS 66988-04-3) is an anionic surfactant derived from isostearic acid and lactic acid, supplied as the sodium salt. It is commercially available under trade names including Pationic ISL and Risolact DIS. No E-code designation applies to this ingredient.

In personal care formulations, it functions as an emulsifier by reducing interfacial tension between oil and water phases, stabilising creams and lotions at low use levels. In food-adjacent and nutritional applications, it modifies rheology by interacting with proteins and starches, improving texture and processing consistency in emulsified systems.

Sodium Isostearoyl Lactylate is supplied in compliance with REACH registration requirements for the European market. Procurement teams should confirm grade suitability against relevant cosmetic or food-contact specifications prior to use.
