TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (I) comprises: providing a solution of hydrogen peroxide, contacting the solution with a alpha -amino acid and precipitating the alpha -amino acid hydrogen peroxide solvate and separating the same from the solution. Preferred Components: The side chain of the alpha -amino acid is non-polar. The alpha -amino acid is glycine, valine, leucine, isoleucine, norleucine, 2-aminobutyric acid or phenylalanine. The side chain of the alpha -amino acid contains one or more polar functionalities. The polar functionality is hydroxyl group. The alpha -amino acid is serine, threonine or tyrosine. (I) has a structure of formula alpha -amino acid.x(H2O2).y(H2O), where the side chain of the alpha -amino acid is: (i) the side chains of proteinogenic alpha -amino acids, excluding the basic proteinogenic alpha -amino acids; (ii) structural isomers or homologs of proteinogenic alpha -amino acid side chains, when the side chains are alkyl groups; and (iii) hydroxy-substituted derivative of proteinogenic alpha -amino acid side chains.x = 1/3-4 (preferably 1.5 or 2); andy = 0-1 (preferably 0-0.5).(I) are anhydrous. (I) are characterized by differential scanning calorimetry curve exhibiting a melting endotherm followed by a distinct exothermic peak. (I) have hydrogen peroxide content of not less than 18 wt.%. The beta -amino acid hydrogen peroxide solvate is crystalline beta -alanine dihydrogen peroxide solvate. The hydrogen peroxide solution is an aqueous solution having concentration of not less than 50 (preferably not less than 70)%, and the alpha -amino acid hydrogen peroxide solvate prepared is anhydrous. Preferred Process: The process-1 further comprises removing the organic solvent from the anhydrous organic solution of hydrogen peroxide to form essentially pure hydrogen peroxide. ACTIVITY - Antiseborrheic; Dermatological; Antiulcer; Antimicrobial.    MECHANISM OF ACTION - None given.    SPECIFIC COMPOUNDS - 11 Compounds (I) are specifically claimed e.g. L-serine hydrogen peroxide solvate of formula (C3H7NO3.H2O2), L-tyrosine dihydrogen peroxide solvate, glycine hydrogen peroxide sesquisolvate, L-phenylalanine hydrogen peroxide solvate hemihydrate and L-serine 0.91 hydrogen peroxide solvate 0.09 hydrate.    EXAMPLE - L-serine (20 g) was dissolved in 70% aqueous hydrogen peroxide solution (20 ml) in a flask. The solution was allowed to stand at 0 degrees C for one week, following which crystals were formed. The crystals were separated from the mother liquor by decantation, washed twice with dry ethyl acetate, and dried in a vacuum desiccator for two hours. The crystals were stored in a desiccator under refrigeration. The product obtained was identified as L-serine mono hydrogen peroxide solvate (85%).
