| titleOfInvention | Stabilizing method of aqueous solution of urocanic acid |
| abstract | PURPOSE: To prepare a stable aqueous solution of urocanic acid usable for a cosmetic having an ultraviolet light absorbing action, by preventing the discoloration of the solution due to the urocanic acid with Na or K salt of tripolyphosphoric acid or tetrapolyphosphoric acid added thereto. n CONSTITUTION: An aqueous solution of urocanic acid in an alkali is mixed with 0.01W1.0wt% one or two or more types of sodium and/or potassium salts of tripolyphosphoric acid or tetrapolyphosphoric acid to prevent the discoloration by light, heat, air, etc. with time into yellow brown to give a stable aqueous solution thereof. n COPYRIGHT: (C)1981,JPO&Japio |
