Abstract
The present invention relates to a liquid, substantially anhydrous eutectic mixture comprising a principal acid component, such as a hydroxy acid, and at least one other component selected from the group consisting of a carbohydrate, a polyol, an amino acid, and a carboxylic acid. The mixtures remain liquid at room temperature, are relatively non-irritating, and can be used to deliver higher levels of the principal acid than would ordinarily be possible. The invention also provides a method of making such a mixture comprising heating the component having the lowest melting point to the temperature at which it melts, dissolving the remaining component or components in the melted component, and allowing the mixture to cool.
