What Is Castor Oil Ethoxylate?
Castor oil ethoxylates are a very important class of surfactants that find themselves in many industrial applications and market segments. Derived from the bio-renewable extract from the seed of the castor plant (Ricinus communis), this vegetable oil is then further processed via ethoxylation to instill distinct physical properties that impart surface-active qualities to the product. This unique feature of surface-activity allows ethoxylated castor oils to increase mixing between two immiscible materials (e.g. oil and water), putting this class of compounds into the category of surfactants.
Oxiteno’s broad portfolio of ethoxylated castor oils (ALKEST® CSO series and SURFOM® R series) are great examples of the vast array of physical properties that can be attributed to the various forms of ethoxylated castor oils. These lines of ethylene oxide condensates of castor oil have an extensive assortment of physical properties to choose from, including a varied range of hydrophilic-lipophilic balances (HLBs), viscosities, and hydrogenated alternatives. All of Oxiteno’s castor oil ethoxylates are compatible in a variety of formulations that vary in their pH, salinity, and solids percent.
Castor Oil Ethoxylate Uses
Castor oil ethoxylates find many uses in a variety of industries, because this class of compounds are versatile emulsifiers, solubilizers, emollients, dispersants, and lubricants. Due to the many potential areas of applications, Oxiteno’s ALKEST® CSO and SURFOM® R series are used in various applications by agricultural, oil & gas, textile, cosmetic and metal-working industries.
In particular, the SURFOM® R series of ethoxylated castor oils have been engineered by agricultural chemical companies to fit the needs of the agricultural industry, where they are excellent solubilizers and dispersants of many pesticides and herbicides. Other markets are commonly served by Oxiteno’s alternative line of castor oil ethoxylates, ALKEST® CSO, which have been developed to act as pigment dispersants, oil-in-water emulsifiers, and lubricants.
All of Oxiteno’s ethoxylated castor oil products are sourced from bio-renewable organic materials. Oxiteno is helping to evolve markets to increase the bio-renewable content of surfactants as well as push the boundaries of innovation for the future of our environment and communities. We aim to decrease our carbon footprint on the environment while continuing to provide our markets with the most efficient, cost-effective, and safe surfactant-based products.
