A a polyaluminum dialkyl phosphate is discosed. The compound is prepared by the reaction of: (A) a dialkyl phosphate represented by formula (I): wherein R1 and R2 independently represent a hydrocarbon group of a C8-26 carbon atom content, or a salt thereof, and (B) a basic polyaluminum salt represented by formula (II): Alm(OH)nX1.kH2O (II) wherein X represents an anion having a valency of x other than a hydroxyl ion, m represents a positive integer satisfying the equation: 3m = n + x1, and k represents 0 or a positive integer, in an aqueous medium in which the resulting polyaluminum dialkyl phosphate is insoluble. The polyaluminum dialkyl phosphate, when it is formulated into a liquid oil, provides a highly transparent, densely structured, soft gel which contains only small amount of free oil component. The gel posseses favorable rheological characteristics and can adequately disperse by a stress and imparts a good feeling upon use.
