Abstract
The present invention relates to a composition of branched fatty acids or esters thereof, the process for preparing such a composition and its use in various industrial fields, such as in lubricant, in cosmetics and in home care. More particularly, the present invention relates to a composition comprising at least 30% by weight of polybranched C10-C24 fatty acids or esters thereof, and a cyclic compound content ranging from 1% to 8% by weight, the weight percentage being given on the total weight of the composition.
Claims16
A composition of branched C10-C24 fatty acids or esters thereof, comprising:
- at least 30% by weight of polybranched C10-C24 fatty acids or esters thereof, and
- 1 to 8% by weight of cyclic compounds,
- weight % being given on the total weight of the composition.
A process for preparing a composition of branched C10-C24 fatty acids from a starting material comprising at least 70% by weight of linear monoethylenically unsaturated C10-C24 fatty acid(s) based on the total weight of the starting material, comprising the following steps:
- i) isomerizing the linear monoethylenically unsaturated C10-C24 fatty acid(s) from the starting material, by heating in the presence of a clay catalyst,
- ii) separating the monomeric fraction from the oligomeric fraction formed during step i), and
- iii) purifying the monomeric fraction to obtain the composition of branched C10-C24 fatty acids.
