FAME (Fatty acid methyl esters) such as Coconut methyl ester or Soya methyl ester etc. can be ethoxylated directly using our patented catalyst system to give methyl ester ethoxylates. methyl ester ethoxylates are low foaming, non-ionic surfactants compared to fatty alcohol ethoxylates.
Their wetting strength is comparable to fatty alcohol ethoxylates of equivalent alkyl chain. They do not form gels as fatty alcohol ethoxylates. CMC and cloud point can be adjusted based on alkyl chain length or degree of ethoxylation. methyl ester ethoxylates also show a narrow homologue distribution. methyl ester ethoxylates show high biodegradability and have a more favourable ecotoxicity profile as compared to fatty alcohols.
Methyl ester ethoxylates can work as excellent emulsifier and detergent. They also help in building viscosity in low active formulations. methyl ester ethoxylates have application in detergents, personal care cleaning agents, hard surface cleaners, emulsifiers, laundry pre-spotters etc.
