An organic hydroxyl compound is reacted with a phosphorylating agent comprising phosphorus pentaoxide and at least one compound selected from the group consisting of water, phosphoric acid and polyphosphoric acid and having a value represented by formula (I) of from 0.5 to 1.0, under such a condition that the ratio as defined by formula (II) has a value in the range of from 2.8 to 3.2; or alternatively, an organic hydroxyl compound is reacted with the above phosphorylating agent under such a condition that the ratio as defined by formula (II) has a value in the range of from exceeding 3.2 up to 6.4 and then phosphorus pentaoxide is added to the reaction product in such an amount that the ratio as defined by formula (II) has a value in the range of from 2.8 to 3.2 with respect to the total feeds of the starting materials to conduct further reaction. Said process enables the preparation of a phosphoric ester mixture which is excellent in hue and odor, is reduced in the amount of orthophosphoric acid formed as a by-product and contains a phosphoric monoester useful as the component of detergent in an increased amount.

An organic hydroxyl compound is reacted with a phosphorylating agent comprising phosphorus pentaoxide and at least one compound selected from the group consisting of water, phosphoric acid and polyphosphoric acid and having a value represented by formula (I) of from 0.5 to 1.0, under such a condition that the ratio as defined by formula (II) has a value in the range of from 2.8 to 3.2; or alternatively, an organic hydroxyl compound is reacted with the above phosphorylating agent under such a condition that the ratio as defined by formula (II) has a value in the range of from exceeding 3.2 up to 6.4 and then phosphorus pentaoxide is added to the reaction product in such an amount that the ratio as defined by formula (II) has a value in the range of from 2.8 to 3.2 with respect to the total feeds of the starting materials to conduct further reaction: ##EQU1## The above process produces a phosphoric ester mixture that is excellent in hue and odor, is reduced in the amount of orthophosphoric acid and contains a phosphoric monoester useful as a component of a detergent.

The present invention relates to a detergent composition which is primarily used on the skin, and more particularly to a detergent composition which provides comfortable and smooth touch on the skin after cleansing. These compositions comprise:

A framed soap composition comprises (a) from 20 to 50% by weight of a fatty acid soap, (b) from 1 to 15% by weight of a nonionic surfactant, and (c) from 0.1 to 5% by weight of an inorganic salt. A framed soap composition incorporated with air bubbles is produced by melting a mixture containing these components while heating the mixture in the presence of water, subjecting the resultant molten material to aeration treatment to incorporate air bubbles, and pouring the resultant molten material incorporated with air bubbles, into a frame followed by cooling to harden the molten material.

Framed soap composition containing non-ionic surfactant and inorganic

A composition for a hair treatment agent comprising as essential components: a chelating agent having a specific chelating value with respect to the chelation of the calcium ion, and a polymer compound selected from a group consisting of cationic polymers containing quaternary nitrogen, and peptides of an average molecular weight of 40 to 10,000, or their derivatives. The composition provides a perm-treatment with a good finishing effect by depressing absorption of calcium to the hair when it is perm-treated. It also serves as a shampoo, by further formulating an anionic or amphoteric surface active agent, which gives an excellent effect of suppleness and smoothness after washing and rinsing to hair which is damaged from a perm treatment.

Composition for hair treatment agent

A phosphoric ester salt of high purity is produced by converting a phosphoric ester in a mixture containing the phosphoric ester and one or more nonionic compounds into a phosphoric ester salt by using a basic compound, and extracting nonionic compounds from the above mixture by using a mixed solvent of aliphatic hydrocarbons or cycloaliphatic hydrocarbons, a lower alcohol and water. The above method is applicable to a non-crystalline phosphoric ester from which nonionic compounds cannot be removed by recystallization. The above obtained phosphoric ester salt of high purity can be used as it is or after condensation.
