Methyl esters of cottonseed oil acids

Methyl esters of cottonseed oil acids (CAS 61788-60-1), also referenced commercially as cottonseed oil fatty acid methyl esters, are produced by transesterification of cottonseed oil; they function primarily as bio-based lubricants.

Where is Methyl esters of cottonseed oil acids used?

• Plasticizers across multiple industrial sectors
• Textile and leather processing: fiber lubricants and softening agents that improve handle and reduce friction during mechanical processing
• Metalworking: cutting fluids and rolling oils where lubricity reduces tool wear
• Coatings and adhesives: reactive diluents or plasticizing components that improve flexibility and substrate wetting
• Polymer and elastomer compounders use them as processing aids and softeners.

Good to know: The mixed fatty acid ester profile, dominated by oleic, linoleic, and palmitic methyl esters, makes this material a renewable alternative to petroleum-derived oils. Technical grade is the standard commercial offering, with purity and acid value specifications varying by supplier and end-use requirement.
