Castor oil ethoxylate

Castor oil ethoxylates (CAS Number: 61791-12-6) are nonionic surfactants derived from natural castor oil through a controlled ethoxylation process. Castor oil itself is a vegetable oil composed primarily of triglycerides containing conventional fatty acids such as stearic acid, along with the distinctive ricinoleic acid, which contains a hydroxyl functional group. This hydroxyl group provides an active site for ethoxylation, allowing ethylene oxide units to be added to the molecule. The result is a series of castor oil ethoxylates with enhanced water solubility, improved surface activity, and tailored hydrophilic–lipophilic balance (HLB) values.

Castor oil ethoxylates function effectively as emulsifiers, solubilizers, antistatic agents, and lubricants. Their amphiphilic structure enables them to reduce surface and interfacial tension, making them capable of blending immiscible substances such as oil and water into stable emulsions. This property is especially valuable in formulations that require uniform dispersion of active ingredients. In addition, their nonionic nature ensures compatibility with a wide range of other surfactants and formulation components across different pH conditions.

Physically, castor oil ethoxylates are typically pale yellow, viscous liquids, reflecting the natural origin of the base oil. They are widely used in both industrial and domestic applications throughout India and global markets. Common uses include textile processing, agrochemical formulations, metalworking fluids, detergents, personal care products, and pharmaceutical preparations. Their lubricating and antistatic properties make them particularly beneficial in fiber treatment and industrial processing, while their emulsifying and solubilizing abilities are essential in cosmetic and healthcare formulations.

We manufacture ethoxylated castor oil products with ethoxylation levels ranging from 2 to 200 moles, allowing customization according to customer requirements. By adjusting the degree of ethoxylation, we provide products with varying HLB values and performance characteristics to suit specific applications. In addition to castor oil ethoxylates, our portfolio includes Hydrogenated Castor Oil ethoxylates and Tall Oil derivatives, offering a comprehensive range of high-quality ethoxylated products designed to meet diverse industrial, cosmetic, pharmaceutical, and agrochemical needs.
