    Abstract: An aromatic deviative of butyric acid has the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, each independently, represent hydrogen or alkyl, with at least two of R.sub.1 -R.sub.4 being other than hydrogen,A represents methylene or dimethylene; when A represents dimethylene, R.sub.1 and R.sub.3 can together form methylene or dimethylene,R.sub.5 and R.sub.6 represent hydrogen, halogen, alkyl, alkoxy or hydroxy,R' represents hydrogen, hydroxy, alkoxy or acyloxy,R" represents hydrogen or alkoxy, or R' and R" taken together form oxo or hydroxyimino,R.sub.8 represents hydrogen or alkyl andR.sub.7 represents --OR.sub.9 or ##STR2## R.sub.9 represents hydrogen, alkyl, monohydroxyalkyl, polyhydroxyalkyl, aryl or aralkyl, optionally substituted, a sugar residue, carboxyalkyl or alkoxycarbonylalkyl,r' and r" represent hydrogen, alkyl, monohydroxyalkyl optionally interrupted by a heteroatom, polyhydroxyalkyl, aryl or benzyl optionally substituted, amino acid residue or aminated sugar residue, or r' and r" taken together form a heterocycle, optionally substituted by a C.sub.1 -C.sub.3 hydroxyalkyl, and to the salts of the compounds of formula I, to their optical isomers as well as the tautomers of the compounds of formula I. These aromatic derivatives of butyric acid are useful in human and veterinary medicines as well as in cosmetic compositions.
