Abstract: Phosphoric esters (mono-, di- or triester) is useful as, for example, a cleaner, an emulsifier, an antistatic agent, metal-chelating agent and a lubricant for fibers. It is produced at a high yield while completely trapping the hydrogen chloride gas formed as a by-product. The reaction between a phosphorus oxyhalide and an organic hydroxyl compound to produce a phosphoric ester is effected in the presence of a metal salt of an acid having a pKa of from -5 to 13.

Abstract: The present invention relates to organo(poly)siloxanes modified by phosphates (including alkali metal salts thereof or the like) suitable as a component of cosmetics, and to a process for the manufacture of organo(poly)siloxanes modified by phosphates (including alkali metal salts thereof or the like) comprising reacting an organo(poly)siloxane having a group HO--(R.sup.4 O).sub.q --R.sup.5' --OR.sup.6).sub.r -- in its molecular chain, wherein R.sup.4 -R.sup.6 are alkylene groups, with an oxyhalogenated phosphorus; and further reacting it with an alkaline solution. These phosphate-modified organo(poly)siloxanes can stably emulsify silicone oils commonly used as cosmetic raw materials, irrespective of temperatures, and exhibit excellent compatibility with polar components and good foaming capability, so that they are suitable as a component of cosmetics such as skin cosmetics, skin detergents, hair cosmetics, hair detergents, and the like.

Abstract: Phosphoric diesters having formula (1): ##STR1## wherein R.sup.1 is an acyl group having at least one phenyl group; R.sup.2 is a C.sub.2-12 linear or branched alkylene group which may optionally be inserted with an oxygen atom between carbon atoms thereof; L is a C.sub.2-40 linear or branched alkyl group which may optionally be inserted with an oxygen atom between carbon atoms thereof or the group R.sup.1 -O-R.sup.2 ; M is a hydrogen atom, an alkali metal ion, a metal ion of di- or higher valence, an ammonium group, an alkanolammonium group having 2 to 14 carbon atoms, C.sub.1-14 alkylammonium group; and n is the valence of M are useful UV absorbing compounds. The phosphoric diesters remain on the skin for long periods of time and exhibit lasting UV shielding effects. The compounds and the cosmetic compositions containing the compounds are very safe to the skin.
