The present invention relates to a hair cosmetic composition including a surfactant and a cationized hydroxypropyl cellulose, wherein the cationized hydroxypropyl cellulose contains a main chain derived from an anhydroglucose represented by the following general formula (1) and has a cationized ethyleneoxy group substitution degree of from 0.01 to 2.5 and a propyleneoxy group substitution degree of from 0.1 to 2.8, wherein R, Rand Rare each independently a substituent group including a cationized ethyleneoxy group and a propyleneoxy group; and n represents an average polymerization degree of the anhydroglucose and is a number of from 50 to 5000. The hair cosmetic composition of the present invention exhibits a less stickiness after use and is capable of imparting excellent run fingers through hair, coating feel and manageability to hair.

Hair cosmetic

An additive for internal addition, which improves the paper qualities of a pulp sheet, such as stiffness and bulk which includes a polymer emulsion containing a natural cationic polymer (A) or synthetic cationic polymer (A') and polymer particles (B) containing vinyl monomer-derived structural units.

Paper quality improver

This invention provides water-absorbing polymer particles suitable particularly for cosmetics, wherein silicone can be stably present on the surface of a water-absorbing polymer even in various formulations thereby giving dry feeling in use even after water absorption. The silicone-modified water-absorbing polymer particles of this invention comprises water-absorbing polymer particles coated thereon via chemical bonding, with a silicone compound having at least one functional group.

Polymer emulsion and process for preparing the same

The invention relates to disintegrating particles formed by agglomerating primary particles at least part of which are insoluble in water, wherein the agglomeration of the disintegrating particles is disintegrated in an aqueous solution containing a water-soluble salt by lowering the concentration of the water-soluble salt. The invention also relates to a cleanser or detergent composition that includes the disintegrating particles, a water-soluble salt at a concentration lower than its saturated solubility, a surfactant and water. The composition has excellent physical (mechanical) cleanability and stability with time and gives users a pleasant feeling upon use. The composition does not cause damage to and itch on the skin because the disintegrating particles are disintegrated during cleansing and rinsing, and it is extremely good in rinsability.

Disintegrating particles and cleanser or detergent composition

The present invention provides a polymer emulsion which contains polymer particles having an average particle size of not more than 30 &mgr;m and having core-parts and shell-parts; which is composed of chitosan (a) and a polymer (b) of organic acids having a reactive vinyl group or a salt thereof, as constituent component of shell-part, and composed of a polymer (c) of hydrophobic monomers, as constituent component of core-part. Further, the present invention provides a coloring agent particle comprising a polymer particle in the above-mentioned polymer emulsion; and wherein a coloring material (k) is present in the shell-part and/or core-part. Furthermore, the present invention provides a deodorizing fiber wherein a polymer particle in the above-mentioned polymer emulsion is present on the surface of the fiber.

Porous particulate and cosmetic

A propylene (co) polymer terminated with a reactive group and a process for the preparation of the same. A graft copolymer having a specific side chain and a process for the preparation of the same. The propylene (co) polymer is usable as a radial- or ion-polymerizable propylene macromonomer or as an intermediate for the preparation of a block polymer. Examples of the application thereof include compatibizing agent for polymers, light- or laser-curable plastic, viscosity index and surface modifier. The graft copolymer is useful as a surface modifier or compatibilizing agent for polypropylene or a dispersant for fillers.
