The present invention is directed to a fluorescent polarization assay for salicylate, to the various components needed for preparing and carrying out such an assay, and to methods of making these components. Specifically, tracers, immunogens and antibodies are disclosed, as well as methods for making them. The tracers and the immunogens are made from substituted benzoic acid compounds. A fluorescein moiety is included in the tracer, while a poly(amino acid) forms a part of the immunogen. The antibodies are prepared in response to the immunogen. The assay is conducted by measuring the degree of polarization retention of plane polarized light that has been passed through a sample containing antiserum and tracer.

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 R.sub.1 denotes a saturated or unsaturated aliphatic group containing from 1 to 18 carbon atoms.
