    Abstract: 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.

    Abstract: Metal salts of monoalkyl phosphates of the following formula (I) in which each R represents a saturated or unsaturated, linear or branched hydrocarbon group having from 8 to 32 carbon atoms, and M represents an alkaline earth metal or divalent transition metal. The metal salts are particularly suitable as cosmetic powders, fillers for resins, and lubricants, parting agents and pigment dispersants for polymeric compounds. When used as cosmetic powders, the metal salts improve spreadability, moistness, smoothness, adherence, transparency and covering power of cosmetics. Preparation process of the metal salts is also disclosed.
