PURPOSE: A fomentation that contains a high-polymer gel mainly consisting of an aluminum salt of water-soluble aliphatic carboxylic acid polymer, thus showing good self-form retention, humectation, thermal stability and good moisture release. n CONSTITUTION: An aqueous solution of a polymer of a polymer aliphatic carboxylic acids such as (meth)acrylic acid, maleic anhydride or their salts such as alkali metal or amine salts is combined with an aluminum compound with a small solubility in the solvent of the solution and they are allowed to react in the presence of an organic acid bearing hydroxyl groups in its molecule at a pH of 4.0W7.0 to form a synthetic high-polymer gel. Then, the resultant gel is added to the base composition of the fomentation. The amount of the polymer, when the gel is prepared, preferably ranges from 0.5W10%. n COPYRIGHT: (C)1985,JPO&Japio |
