Document Type and Number:
Japanese Patent JP2804081
Kind Code:
B2
Abstract:
The present invention relates to a process for the preparation of nonionic surfactants from fatty acid alkyl esters, mono- or polyhydroxy fatty acid alkyl esters with C6-C22 in the fatty acid component and C1-C4 in the ester component, which are reacted in alkaline medium with one or more isopropylidene derivatives of a polyglycerol at temperatures of 140-220 DEG C and under a vacuum of 950-5 mbar. The resulting C1-C4-alcohol is removed by distillation, and the subsequently purified reaction product is hydrolysed by cleaving at least one isopropylidene group of the reaction product at 20 to 100 DEG C and under atmospheric, subatmospheric or superatmospheric pressure by acid hydrolysis.The invention also relates to the use of the surfactant and to skin-care or cosmetic preparations and paints as well as wood preservatives using the nonionic surfactant.
