Sodium ricinolate

Sodium ricinolate (CAS 5323-95-5, EC 226-191-2) is the sodium salt of ricinoleic acid, a fatty acid derived from castor oil. It is also referenced under the names sodium ricinate, soricin, colidosan, and NSC 2835. No E-code has been assigned to this substance.

In personal care and pharmaceutical manufacturing, sodium ricinolate functions as an emulsifier by reducing interfacial tension between oil and water phases, stabilizing formulations such as creams and medicated lotions. In textile and leather processing, it acts as a degreasing and dispersing agent, helping to remove lipid-based contaminants from fiber surfaces during wet processing.

Sodium ricinolate is supplied as a white to slightly yellow powder and is available in technical and cosmetic-grade specifications. It falls under REACH registration requirements for EU market supply. Standard packaging formats for industrial procurement include fiber drums and multi-layer bags; buyers should confirm grade suitability against relevant pharmacopoeial or industry standards.
