  • Amino fruit acid composition and method for the treatment of skin
    Patent number: 6703030
    Abstract: A composition for the treatment of skin consists essentially of a carboxylated, acidic amino acid obtained by acidifying an acidic amino acid with a carboxylic acid. The resultant material, which is also referred to as a tricarboxylic acid or an amino fruit acid, has significant benefit for the treatment of a number of skin conditions. In addition, the composition of the present invention is very noncaustic to skin, even when employed at a pH as low as 0.5. Also disclosed herein are therapeutic methods and compositions which employ the carboxylated acidic amino acids.

  • Composition and method for the treatment of skin
    Patent number: 6197317
    Abstract: A composition for the treatment of skin includes an alpha amino acid, which is most preferably an alpha amino dicarboxylic acid such as aspartic acid or glutamic acid. The composition has a pH in the range of 0.5 to 5. Also disclosed is a method for preparing the compositions wherein the amino acid is first solubilized in a strong acid, and the resultant solution then neutralized with a base to the therapeutic pH range. Also disclosed is a carrier for dermatological compositions comprising a solution of ascorbic acid and mineral salts.

  • Medicinal facial mask
    Patent number: 5599546
    Abstract: A class of dermatological compositions and method of treating various skin conditions. The compositions includes an acidic material selected from the group consisting of alphahydroxy acids, carboxylic acids, halocarboxylic acids, dicarboxylic acids, and combinations thereof, a limonene-based oil, an absorbent carrier, and water. The compositions are applied to the skin as a facial mask and allowed to dry. The compositions both degrease the skin, and deliver therapeutic agents to the skin on a time release basis.
