-
Paragraph 0020-0032, (2021/08/06)
The invention discloses a preparation method of 5-capryloyl salicylic acid, and belongs to the technical field of organic synthesis. The method comprises the following steps of: adding capryloyl chloride and salicylic acid as raw materials into a solution of a composite catalyst consisting of lewis acid and tris (pentafluorophenyl) borane, carrying out Friedel-Crafts acylation to obtain 5-capryloyl salicylic acid, carrying out post-treatment, salifying with organic alkali, purifying, and then dissociating to obtain a product. The operation is simple, the product with the purity of 99.7% can be obtained at one time, and the three wastes are few.

Topical compositions intended for skin treatment and based on salicylic acid derivatives. The invention relates to topical compositions with a keratolytic and/or comedolytic effect, containing, in a carrier which is suitable for application to skin, at least one compound corresponding to the formula I: STR1 in which R denotes a linear, branched or cyclized saturated aliphatic chain containing from 3 to 11 carbon atoms, an unsaturated chain containing from 3 to 17 carbon atoms and containing one or more conjugated or unconjugated double bonds, these various substituents being optionally substituted by one or more halogen atoms, by one or more trifluoromethyl groups, by one or more hydroxyl groups in free form or esterified with an acid containing from 1 to 6 carbon atoms or by a carbonyl group which is free or esterified with a lower alcohol containing from 1 to 6 carbon atoms, R' denotes a hydroxyl group or an ester group of formula: STR2 where R1 denotes a saturated or unsaturated aliphatic group containing from 1 to 18 carbon atoms.
