Description

Sodium ricinoleate (CAS 5323-95-5 ), also known commercially as Colidosan and Soricin, is the sodium salt of ricinoleic acid derived from castor oil. It functions as a natural surfactant, emulsifier, and foam modifier across personal care, pharmaceutical, and industrial processing applications. In personal care formulations, it acts as the active cleansing and lathering agent in soap bars and liquid cleansers, contributing mild foam with good skin compatibility. Pharmaceutical manufacturers use it as an emulsifying and dispersing agent in topical preparations and suppository bases. Textile and leather processors rely on it for scouring and degreasing operations, where it removes oils and contaminants from fiber and hide surfaces without harsh synthetic inputs. In food-contact and industrial cleaning contexts, it functions as a degreasing surfactant where bio-based chemistry is a sourcing priority. Sodium ricinoleate is supplied as a paste or liquid, depending on concentration and processing method. It is available in technical and cosmetic grades, with cosmetic-grade material meeting purity standards relevant to personal care and pharmaceutical applications. Buyers typically source it in drum or IBC quantities, with bulk availability from castor oil processing regions. This versatile compound offers a sustainable alternative to synthetic surfactants in high-performance formulations. Contact us for supply of Sodium ricinoleate Request Quote
