SOLUTION: The colorant-containing aqueous polymer dispersion comprises (a) (i) a polymer matrix to be prepared from an ethylenically unsaturated monomer M and (ii) colorant-containing polymer particles which are uniformly dispersed in the above polymer matrix and contain at least one organic colorant C to be selected from a dye, an UV absorber, and a fluorescent brightener and, simultaneously, have an average particle diameter d50 of
Abstract:
PROBLEM TO BE SOLVED: To afford a specific polymer with such advantages as reduced solution viscosity and improved rinsability with invariable tonic activity by using itself as a hair setting polymer. SOLUTION: A polymer with a group of formula I [R is H or a (mutually bound) organic group; G is O or NH] is used as a hair setting polymer. It is preferable that the polymer of formula I is produced under the use of a monomer of formula II (R1 is H or CH3) (e.g. ureidomethacrylate), or comprises repeating unit of formula III; specifically, the polymer of formula I is pref. such one as to be produced by copolymerization between two kinds of monomer each bearing olefinic double bond, namely, 0.05-100 wt.% of the monomer of formula II and 0-99.95 wt.% of another copolymerizable monomer.

PROBLEM TO BE SOLVED: To obtain a cosmetic composition highly easily rinsable, affording the hair with smoothness and luster, and useful as a hairdressing composition, by including polytetrahydrofuran, a polyester diol, a polyurethane, etc. SOLUTION: This cosmetic composition is obtained by including (A) at least one kind of polymer having two active hydrogen atoms in one molecule, selected from polytetrahydrofuran, polysiloxanes and mixtures thereof, (B) at least one polyester diol, (C) a compound with a molecular weight of 56-300 having two active hydrogen atoms in one molecule, (D) a compound having in one molecule two active hydrogen atoms and an anion-forming or anionic group, and (E) at least one polyurethane or salt thereof, a water-soluble or water-dispersible one, having no unit derived from primary or secondary amine bearing ion- forming or ionic group at all.
Abstract:
PROBLEM TO BE SOLVED: To provide a light-protective agent for cosmetics/dermatology capable processing easily in oil or water, which absorbs ultraviolet rays in UV-A range at high absorbance and which is photostable and has a weak specific color. SOLUTION: A preparation for cosmetics or dermatology comprises a) 3,3- diphenylacrylic ester of formula I of 0.1-10 weight % (wherein R1 and R2 is a hydrogen atom, 1-12C alkyl group or 1-12C alkoxy group; R3 is a 3-10C cycloalkyl group which may be substituted; R4 is a hydrogen atom or CN) and b) dibenzoylmethane derivative of formula II of 0.1-10 weight % (wherein R5 to R8 is a hydrogen atom or 1-4C alkyl group; R9 and R10 is a hydrogen atom, 1-12C alkyl group or 1-12C alkoxy group).
Abstract:
PROBLEM TO BE SOLVED: To provide a processing method of cosmetic composition which makes it possible to improve trimming hair of head and skin. SOLUTION: The process by near-infrared radiation (NIR-radiation) prior to, during or after applying the cosmetic composition is provided.
Abstract:
The invention relates to cosmetic and/or pharmaceutical preparations composed of polymers containing polysiloxanes which are soluble in water or can be dispersed therein, in addition to other polymers and /or filters protecting against ultraviolet light. The invention also relates to the use of such preparations and the use of polymers containing polysiloxanes.
