Sulfonated Castor Oil is an anionic surfactant produced by the sulfation of castor oil. It provides effective wetting, emulsifying and solubilizing properties, with a pH of 6.5–7.5 in a 10% aqueous solution. Contact with multivalent metal ions should be avoided to reduce the risk of precipitation. Polykem supplies stable-quality grades for textile, leather and industrial applications. Welcome to inquire.
Polykem supplies Sulfonated Castor Oil, also known as Turkey Red Oil, with controlled solids, pH and SO₃ content to support consistent performance across production batches. Technical specifications, COA, TDS, SDS and samples are available for product evaluation. Contact Polykem to discuss your application and purchasing requirements.
