- Product Background
Croduret are vegetable-derived nonionic surfactants which find widespread use as emulsifiers, wetting agents, dispersants and lubricants. They are commonly used in such diverse applications as textiles and leather processing, printing inks, household products, metalworking fluids, emulsion polymerisation, paper recycling and other auxiliary industries.
Croduret are ethoxylated castor oil and ethoxylated hydrogenated castor oil respectively. Members within each range have different degrees of ethoxylation (moles) as indicated by their numerical suffix. Members with levels of ethoxylation differing from the standard range may be made available on request, subject to minimum batch quantities.
The chemical structure of the Crodurets is analogous to that of Etocas with the exception that the double bond has been saturated by hydrogenation. This results in greater oxidative stability with superior color and odor.- Textiles/leather processing
In synthetic and natural fiber and fabric processing, Croduret are useful as dye carriers/solvents, dye leveling and wetting agents, emulsifiers, lubricants, softeners and spin finishes.
The intermediate members of the Croduret range are employed as emulsifiers and stabilizers for aliphatic/aromatic solvents, phthalic acid esters, hydrocarbons and other principal dye carriers. In particular,
In leather processing Croduret are used as nonionic leveling agents to ensure that the applied dye is evenly dispersed through the leather.- Printing inks
The Croduret range may be used in printing inks as surfactants to improve wetting of pigments and aid ink flow. In duplicator machine inks based on vegetable oils the lower members of the ranges are recommended as emulsifiers and stabilizers.
In auxiliary market applications Croduret are effective vegetable oil emulsifiers in blanket roller cleaners and plate and screen cleaners.- Household products
The Croduret range can be used in many household product systems as solubilisers, detergents or emulsifiers. The higher molar ethoxylates are effective solubilisers for the fragrances used in household air freshener products, including gels and liquids.

Croduret are effective emulsifiers for oils, solvents and waxes. The less ethoxylated members of the ranges (5-30 moles) have HLB values below 12. Above this level of ethoxylation the products exhibit HLB values ranging from 12-15. When selecting an Croduret surfactant using the HLB system, it is necessary to consider the range of materials to be emulsified. In some applications, particularly in more sophisticated systems, a blend of surfactants rather than a single surfactant may be more effective.
