  • Patent number: 7749283
    Abstract: The object of the present application is a dye carrier composition containing oxidative and/or non-oxidative dyes as well as (a) 6.1 to 25 weight percent of at least one fatty alcohol with 14 to 20 carbon atoms, (b) 1 to 20 weight percent of at least one fatty acid alkanolamide and (c) 1 to 15 weight percent of at least one fatty alcohol alkoxylate and/or fatty acid alkoxylate, the weight ratio of fatty alcohol (a) to fatty acid alkanolamide (b) being equal to 4:1 to 1:3 and at the same time the weight ratio of fatty alcohol (a) to alkoxylate (c) being equal to 5:1 to 1:2. Another object is the use of the afore-said combination of components (a) to (c) to produce a nacreous luster effect in dye carrier compositions and colorants for keratin fibers.

  • Publication number: 20050081311
    Abstract: The colorant for dyeing keratin fibers contains oxidation dye precursors and/or direct dyes and a combination of from 2 to 12 percent by weight of at least one long-chain fatty alcohol, from 2 to 12 percent by weight of at least one alkanolamide, from 0.5 to 10 percent by weight of at least one fatty alcohol alkoxylate and from 0.5 to 10 percent by weight of at least one quatemary ammonium compound. The weight ratio of fatty alcohol to alkanolamide is from 0.5:1.5 to 1.5:0.5. A method of making the colorant is described.

  • Patent number: 6365136
    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.
