Abstract: The present application relates to a multicomponent kit for dyeing keratin fibers which consists of (i) a dye carrier mass (A) which is free from dyes and dye precursors; (ii) a granular composition (B) which comprises at least one oxidation dye precursor and/or at least one direct dye and optionally at least one keratin-lightening or bleaching substance; and optionally (iii) a suitable oxidizing agent (C); to a method for dyeing keratin fibers and to the use of a combination of a dye-free dye carrier mass (A) and a granular dye-containing and optionally bleaching-agent-containing composition (B) and optionally an oxidizing agent (C) for the individual preparation of colorants for keratin fibers directly prior to dyeing or bleaching the keratin fibers.

Abstract: The colorant for keratin fibers contains direct and/or oxidative dyes as well as a perfume system consisting of an encapsulated perfume and an unencapsulated perfume of the same composition. The ratio of encapsulated perfume to unencapsulated perfume is equal to about 0.5:3 to 3:0.5. The perfume system is used for removing or masking the unpleasant odor of alkalinizing agents in the colorant.

Abstract: The present patent application relates to dye-containing pellets obtained by (a) homogeneous mixing of a starting material containing at least one natural and/or synthetic dye with a suitable carrier material and then coating with a suitable encapsulation material or (b) coating a suitable carrier material with a mixture of at least one natural and/or synthetic dye and at least one suitable encapsulation material, to the use of said pellets for preparing colorants for keratin fibers and to the colorants based on said pellets. Furthermore the present patent application relates to the use of these pellets for increasing the shine of the keratin fibers, reducing the scalp coloring of hair dyes, improving the protection for the cortex, increasing the colorant efficiency and reducing the load of colorants, and improving the wash resistance.

Abstract: The present invention relates to an agent for coloring keratin fibers which is free of chemical oxidants and is in the form of an aqueous or aqueous-alcoholic preparation and contains a combination of oxidation dyes and direct dyes, said combination containing at least three direct dyes, and that the quantitative ratio of oxidation dyes to direct dyes is equal to 5:1 to 0.5:1.

Abstract: A method of conditioning and oxidatively dyeing human hair includes applying an oxidative hair dyeing composition to the human hair in order to dye the human hair and, simultaneously or subsequently to the applying of the oxidative hair dyeing composition, applying a particular hair conditioning composition to the hair. This hair conditioning composition has a pH value of from 3.4 to 3.9, which corresponds to an isoelectric point of the human hair, and contains from 0.001 to 2.5% by weight of a cationic polymer, an optional pH buffer and preferably additional conditioning ingredients, such as a cationic surfactant and/or a fatty alcohol.

Abstract: The composition for removing or lightening hair color is in the form of a hair color lightening suspension and is mixed with an aqueous oxidizing composition immediately prior to use. The composition includes a combination of from 0.1 to 80 percent by weight of one or more organic lipophilic compounds, namely vegetable or animal fats, vegetable or animal oils, vegetable or animal waxes, paraffin hydrocarbons, higher alcohols or ethers, aliphatic and aromatic esters and/or silicone oils; from 0.1 to 40 percent by weight of at least one lipophilic inorganic or organic thickener, which forms an oleogel and/or lipogel with the lipophilic compounds; from 0.1 to 40 percent by weight of one or more hydrophilic inorganic or organic thickeners; from 10 to 65 percent by weight of at least one inorganic persalt; from 10 to 45 percent by weight of at least one alkaline reacting salt; and auxiliary substances and cosmetic additive ingredients, as needed.

Abstract: The dye carrier composition for oxidative dyeing of hair advantageously includes a combination of about 0.01 to 5 percent by weight of developer substance and about 0.01 to 5 percent by weight of coupler substance, from 0.1 to 10 percent by weight beeswax and from 0.1 to 10 percent by weight of one or more protein hydrolyzates and/or amino acids. The composition can also contain 0.1 to 30 weight percent of an non-ionic and/or anionic wetting agent or emulsifier and the protein hydrolyzates preferably include silk protein hydrolyzate and/or keratin hydrolyzate.

Abstract: An ion-selective electrode for determining an electrolyte concentration in an aqueous solution includes an ion-selective layer and a potential-sensitive fluorescent indicator in the ion-selective layer, the fluorescence intensity of the potential-sensitive fluorescent indicator being measured to provide an indication of the electrolyte concentration.
