Abstract:
PROBLEM TO BE SOLVED: To obtain a constituent readily mixable in a cosmetic composition and suitable for imparting a color to the cosmetic composition having advantages of a pigment, the so-called chemically inert behavior toward other constituents of the cosmetic composition and low solubility in water. SOLUTION: This fine dye-containing polymer PD comprises a polymer substrate containing at least one organic dye in the uniformly dispersed form.
Abstract:
A novel hydrogel (I), showing floating behaviour, thickens 40-90% of a solution and/or suspension to be thickened from the fluid surface and the remainder of the solution and/or suspension from the bottom of the container. Independent claims are included for: (1) the preparation of a hydrogel (I'), by post-treating a dried hydrogel with a hydrophobic compound (II) and optionally a hydrophilic compound (III); and (2) mixtures of (I') with auxiliaries, specifically one or more of biocides, antimicrobial or antibacterial agents, perfumes or fragrances, stabilizers, dyes and/or pH indicators.
Abstract:
Cosmetic colorant, comprises a finely-divided polymer in the form of an aqueous dispersion (or a powder derived from such a dispersion), where the polymer matrix contains a homogeneously-distributed organic dye.
Abstract:
The present invention describes the use of finely divided dye-containing polymers PD in the form of an aqueous polymer dispersion or a polymer powder obtainable therefrom, the polymer matrix of which comprises at least one organic dye D in homogeneously dispersed form, as color-imparting constituent in cosmetic compositions. The present invention also describes cosmetic compositions which comprise a color-containing polymer in an amount of from 0.1 to 50% by weight, based on the total weight of the cosmetic composition, and additives customary for cosmetic compositions.
Abstract:
Use of multiply coated lustrous pigments (A) for coloring cosmetic care compositions. An Independent claim is also included for cosmetic care compositions containing, as colorant, 1-50 wt.% (A).
