Description
12-Hydroxyoleic acid (CAS 141-22-0), also known as ricinolic acid or ricinic acid and traded under names such as Nouracid CS 80, is a hydroxylated C18 fatty acid derived from castor oil. It carries no assigned E-code. The abbreviation 12-OH 9c-18:1 reflects its hydroxyl position and unsaturated backbone.
In personal care formulations, it functions as an emollient and skin conditioner by integrating into the lipid barrier and reducing transepidermal water loss. In metalworking and lubricant applications, its hydroxyl and carboxyl groups provide boundary lubrication and metal surface adhesion. Textile and leather processors use it as a wetting and softening agent to improve fiber penetration.
12-Hydroxyoleic acid is supplied as a technical-grade liquid and is subject to REACH registration requirements within the EU (EC 205-470-2, HS code 29181990). Buyers should confirm grade specifications and purity certificates directly with the supplier, as cosmetic-grade material may require additional documentation.
