COMPOSITION OF EXTERNAL PREPARATION AND PROCESS FOR PREPARING THE SAME

摘要

A composition of an external preparation comprising a synthetic polymer gel which can homogeneously gel at any crosslinking rate and does not cause any change in quality with the lapse of time, and a process for preparing the same. The composition of an external preparation comprises a synthetic polymer gel prepared by reacting a water-soluble polymer of an aliphatic carboxylic acid or a salt thereof with a sparingly soluble aluminum compound, an organic acid containing a hydroxyl group in its molecule as a reaction accelerator and an ethylenediamine compound and/or citric acid as a reaction inhibitor in the presence of water at pH 4.0 to 6.1.
