AI Technical Summary
Existing branched fatty acid compositions, such as isostearic acid, are mixtures with varying linear and multi-branched saturated monocarboxylic acids, lacking specific control over cyclic compound content, which affects their low-temperature properties and stability.
A composition with a high content of multi-branched C10-C24 fatty acid or its ester and a controlled low content of cyclic compounds, specifically 1-8% by weight, is developed, achieved through isomerization and purification of linear unsaturated fatty acids using a clay catalyst, followed by separation and esterification.
The resulting composition exhibits improved low-temperature properties, stability, and resistance to ultraviolet light, with a pour point below -40°C, suitable for lubricating oils and cosmetic compositions.
