  • Water soluble triglyceride compositions and method for their preparation
    Patent number: 3970569
    Abstract: Water soluble mixed ester lubricants derived from triglycerides are obtained by transesterifying a triglyceride with a low molecular weight polyoxyethylene glycol in the presence of short-chain mono- or dicarboxylic acids. The mixed ester compositions of this invention are readily water soluble and are excellent lubricants for metalworking operations. Water solubility is achieved with the present mixed ester products even though they have higher triglyceride contents than previously known ester lubricants.

  • Method for treating polymeric fibers
    Patent number: 3959560
    Abstract: Ester lubricant compositions are provided which provide a good balance of lubricity and emulsifiability. The esters are derived from polyoxyalkylene glycols with a dibasic acid mixture consisting of dimer acids and short-chain dibasic acids. The emulsions and clear, homogeneous lubricant solutions provide excellent spin finishes for fibers such as polyamides and polyesters.
