Description

Sodium Castorate is the sodium salt of castor oil fatty acids, a versatile anionic surfactant derived from a renewable natural resource. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a key functional ingredient in numerous industrial formulations. It is essential for manufacturers in the personal care, textile, metalworking, and agrochemical industries seeking effective, biodegradable surfactant solutions.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and surfactant in creams, lotions, soaps, and shampoos.
• Textile Processing: Used as a dye leveling agent, wetting agent, and emulsifier in fiber treatment and finishing.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and coolants.
• Agrochemicals: Functions as an emulsifier and dispersant in pesticide and herbicide formulations.
• Leather Processing: Employed as a fatliquoring agent and emulsifier in tanning and finishing.
• Paint & Coatings: Acts as a pigment dispersant and grinding aid to improve stability and application.
• Industrial Cleaning: Used in heavy-duty degreasers and cleaning compounds for its surfactant properties.
