Description

[Detailed description of the invention] Hydrogen peroxide preparation The present invention can be used as an oxidizing agent formulation for hair bleaching and oxidative dyeing with oxidative dyes. The present invention relates to aqueous formulations of hydrogen peroxide particularly suitable for use.

Bleaching and dyeing hair with oxidative hair dyes is usually done in two individually packaged preparations [bleaching]. cream or oxidizing hair dye cream (A) and oxidizing agent preparation (B)] immediately before application. Mix by simply shaking in the applicator bottle, then apply immediately. by applying it to the hair as a bleaching or dyeing preparation. use at home For this purpose, a mixing and application container with two compartments has also been developed. Component A and component B are separated into the container in an appropriate ratio, and the two components are separated. There are partition walls between the parts, and the partition walls can be mechanically destroyed from the outside. (designed), one of the two compartments has an opening for application. be.

Immediately before use, break the septum and combine components A and B by shaking or other mechanical means. Mix in stages. Then open the opening for applying ready-made hair dye or hair bleaching formulations It can be taken out and applied directly to the hair to be dyed.

To obtain good dyeing results, bleaching or dyeing cream (A) and oxidizing agent preparation ( It is very important to mix B) rapidly and homogeneously. For example composition and Facilitates the mixing process by matching the two components to each other in terms of viscosity Attempts have been made, for example, to It is proposed in No. 7.

The major problem is not only the viscosity difference between the components being mixed, but also the intense foaming that accompanies mixing. It was found that this can occur even if Mechanical mixing of liquid components (A) and (B) The degree of foaming is significantly hindered.

Foaming is particularly important for stabilizing purposes in oxidizing agent formulations (usually aqueous formulations of hydrogen peroxide). This is caused by the presence of highly foaming anionic surfactants. In such preparations In order to achieve viscosity after mixing, alkali-soluble thickening carboxy functional polymer is present, but an anionic surfactant is required to stabilize its dispersion. It is essential. Furthermore, creams for bleaching and oxidative hair dyeing also contain viscosity in such products. High foaming to keep the fatty alcohols present dispersed for the purpose of achieving often contain anionic surfactants. For the above reasons, highly foamable anions Since it is impossible to omit the surfactant, foaming can be adjusted using appropriate additives. The problem arises.

The present invention combines an anionic surfactant and an aqueous alkali-soluble viscosity-enhancing carboxylic surfactant. for the oxidative dyeing and bleaching of hair, containing functional polymers or copolymers. An aqueous hydrogen peroxide formulation having the formula l R1-0(C2H40), -R2(I) [wherein R1 has 10 to 22 carbon atoms] an alkyl or alkenyl group having 6 to 15 carbon atoms in the alkyl group, or is an alkylphenyl group having R”lt (CsHsO)-H,C,H z--+*tali (CsHsO)y-C-Hz-4+ (7) group, and X is 1 ~10, y is a number from 3 to 5, and n is a number from 1 to 4. ] Nonionic surfactant The present invention relates to a formulation containing the agent in an amount of 0.1 to 5% by weight based on the total composition.

The hydrogen peroxide formulations of the present invention are made from an aqueous base of carboquine-functional polymers or copolymers. Preferably it is present in the form of a dispersion. Furthermore, the formulations of the present invention may be emulsified or separated. It may also have a dispersed fatty phase. Hydrogen peroxide content ranges from 1 to 15% by weight based on the entire formulation % is preferable.

Carboquine-functional polymers or copolymers include acrylic acid or methacrylic acid. Preference is given to using polymers or copolymers of lylic acid. Acrylic acid and Polymers and copolymers of methacrylic acid and methacrylic acid are known and are useful as thickeners for aqueous solutions. It has been used for many years. For example, British Published Patent No. 870994 describes acrylic Low acid lower alkyl ester (both 10% by weight, methacrylic acid 25-70% by weight) and optionally other comonomers with a solids content of 25 to 40% by weight of the copolymer. A 50% by weight dispersion is described. 50-75% by weight of ethyl acrylate, a A copolymer of 25-35% by weight of acrylic acid and 0-25% by weight of other comonomers is , known from West German Published Patent Application No. 1164095.

By adding a copolymerizable crosslinkable polyunsaturated comonomer, the copolymer can be The molecular weight of the compound and, concomitantly, its thickening effect can be varied. this Acrylate dispersions which are particularly effective for this purpose are described, for example, in DE 34 45 It is known from No. 549.

Suitable polymers are typically aqueous dispersions (typically viscous liquids) that are stable in the pH range of about 2 to 5. Example solids content: 20-30% by weight). aqueous bases, e.g. alkali metal hydroxides solutions (e.g. sodium or potassium hydroxide), ammonia solutions, alkaline Canolamines (e.g. mono-, di- or triethanolamine) As the pH of the solution is increased and the carboxyl groups are converted to the salt form, the polymer chains are It begins to decompose and dissolve into the solution, and the viscosity of the solution increases. At a pH of about 8, carboxyl Ionization of the groups and increase in viscosity are completed and clear dissolution in water is achieved.

The polymer is present in the formulation of the present invention in an amount of 0.1 to 10% by weight (solid basis) based on the total formulation. Preferably, it is present in an amount of

Seven-, di- or trialkanol ammonium having 2 to 4 carbon atoms in Preferably, it is present in the form of a salt. Anionic surfactants are used throughout the formulation. Preferably, it is present in an amount of 0.1 to 10% by weight.

(preferably linear saturated fatty alcohols) adding X moles of carbon oxide followed by the addition of a relatively non-hydrophilic end group R2. Manufactured by. This terminal group can contain, for example, 3 to 5 moles of propylene oxide. It can be introduced by adding it to Etkin 1 note. In addition to this group, or Instead, an alkyl group -C,R2,. + (n = 1 to 4 carbon atoms) is introduced ethoxylate R'-0 (CzH40), for example in a manner known from the literature. --H is alkyl chloride C1! -C, by etherification with R2-1 , so-called end group closure may be achieved.

Such preparations contain, as a fat component, containing the aforementioned fatty components (preferably cetyl and stearyl alcohol); is preferable. Dyeing cream is a carrier for oxidative dye precursors dissolved in it. function. In the case of bleach, oil-in-water emulsions leave the hair very thick after application. In rare cases, they contain relatively small amounts of oxidative dye precursors that supplement the natural yellow and red colors.

Bleaching and dyeing creams are preferably adjusted to a pH of 8 to 11 and treated according to the invention before application. Mix with hydrogen peroxide preparation.

Therefore, the present invention provides an oxidative hair dye cream in the form of an oil-in-water emulsion with a pH of 8 to 11.
