The solubility in solvent media, notably alcoholic media, of the beta-hydroxy acids ("BHAs"), notably the chemical skin peeling agent salicylic acid, is markedly enhanced by solubilizing same in the presence of at least one alpha-hydroxy acid ("AHA"); higher potency, more concentrated BHA ...

Due to the adaptation of starch derivatives as well as due to the optimisation of processing techniques, it is possible to specifically control the reaction between synthetic polymers and the hydroxy groups of the starch. The results are polyurethane films having the following property profiles due ...
