Definitions
- the present invention relates to a water-based cosmetic composition thickened with xanthan and sodium carboxymethyl cellulose and having a strongly alkaline pH, which is to be used as an alkalizing component in a two- or three-part oxidative hair lightening agent.
- the present invention further relates to a kit which comprises this alkalizing component and a hair lightening method using this alkalizing component.
- oxidative lightening agents require an alkaline pH value to accelerate the reaction, in particular in the range from pH 10.0 to 11.0.
- the oxidizing agent, hydrogen peroxide which is most frequently used for cosmetic purposes, is however only stable in storage at low pH values, i.e. in the range from pH 2.0 to 6.5.
- Commercially available bleaching agents are therefore usually packaged as a kit from an aqueous hydrogen peroxide solution with a more acidic pH value, preferably in the range from pH 2.0 to 6.5, and an alkalizing component. Both components are only mixed with one another shortly before application to the hair.
- Both components are matched to one another in terms of their composition and mixing ratio so that the resulting application mixture has an alkaline pH value, in particular in the range from pH 9 to 10.
- a - usually anhydrous - persulfate-containing composition which intensifies the lightening effect of the bleaching agent can also be added to the alkaline hydrogen peroxide-containing application mixture.
- Such a commercially available bleaching agent is available as a kit consisting of an aqueous hydrogen peroxide solution with a more acidic pH value, preferably in the range from pH 2.0 to 6.5, an - often creamy - alkalizing component and an anhydrous persulfate-containing composition.
- kits described above also contain one or more portions of a hair conditioner for the nourishing post-treatment of the hair after the completed bleaching treatment.
- the application time for appealing lightening results is usually in the range from 5 to 60 minutes. It is therefore necessary that the individual components of the ready-to-use bleaching agent are formulated in such a way that, on the one hand, they can be mixed well with one another and then distributed on the hair to be lightened, and on the other hand, are sufficiently viscous to remain on the hair to be lightened during the application time without falling off drops.
- This viscosity can be adjusted by polymeric thickening agents, this thickening agent being contained both in the alkalizing component and in the oxidizing agent preparation as well as in the optional anhydrous persulfate-containing composition.
- the alkaline pH of the alkalizing component is adjusted with alkalizing agents, mainly ammonium hydroxide or ammonia water or alkanolamines and mixtures of these alkalizing agents.
- alkalizing agents mainly ammonium hydroxide or ammonia water or alkanolamines and mixtures of these alkalizing agents.
- Ammonium hydroxide and alkanolamines, in particular monoethanolamine, are particularly suitable for swelling the cuticle, i.e. the outer cuticle of the keratin fiber, so that the oxidizing agent can penetrate the keratin fiber well and lighten it.
- Basic amino acids and inorganic bases are less suitable as sole alkalizing agents; however, these components can be used as an additional alkalizing agent.
- the alkalizing component is usually mixed with an aqueous hydrogen peroxide solution to form a homogeneous cream or gel and then applied directly to the hair to be lightened.
- an anhydrous persulfate-containing composition can be added to this mixture, which further enhances the lightening and bleaching performance of the agent.
- This bleaching agent remains on the hair for a time of 5 to 60 minutes until the oxidative degradation of the natural melanin hair dyes, i.e. eumelanin and pheomelanin, has been completed to the desired extent. The bleaching agent is then washed out of the hair.
- the degree of melanin degradation and thus the achieved lightening of the hair depends on various properties of the hair, in particular on the original amount of the black-brown pigment eumelanin and the red-gold pigment pheomelanin as well as the structure of the hair fibers.
- a good bleaching agent is able to break down the melanin as completely as possible and not achieve any undesired color tones.
- This property of the bleaching agent is also referred to as leveling power.
- the alkalizing agent or the alkalizing agent mixture are usually incorporated into a cosmetically suitable carrier, such as, for example, a cream or a gel.
- a cosmetically suitable carrier such as, for example, a cream or a gel.
- the carrier ensures a homogeneous distribution and a sufficient residence time of the hair lightening agent on the hair.
- the alkalizing component of an oxidative hair lightening agent is often referred to as a bleaching cream. Fat components with a melting point above 30 ° C are often used as consistency factors for creams.
- higher linear fatty alcohols such as myristyl alcohol, cetyl alcohol and stearyl alcohol
- polyol esters such as glyceryl monostearate, glyceryl distearate, ethylene glycol monostearate and ethylene glycol distearate, but also wax esters such as cetyl palmitate and myristyl myristate oils, as well as hardened oils.
- the disadvantage is the complex production of such a cream, which contains higher-melting consistency factors.
- For melting the fat components and emulsifying with the water phase requires a lot of energy.
- the subsequent cooling process consumes large amounts of cooling water.
- the thickening can also take place by means of a polymer thickener.
- Corresponding alkalization components of the prior art contain polymers or copolymers with acrylate-, methacrylate- or vinyl-containing monomers, eg. B. carbomer, sodium polyacrylate, PVP, amphiphilic polyacrylate copolymers, such as copolymers with the INCI names Acrylates / C 10-30 Alkyl Acrylate Crosspolymer and Acrylates / Steareth-20 methacrylate copolymer, or polyurethanes, e.g. B. PEG-150 / Decyl Alcohol / SMDI Copolymer.
- Such polymers and copolymers are hydrophilic or amphiphilic and form a gel structure in the alkaline aqueous phase. Because of their persistence in the environment, the use of such polymers should be avoided as far as possible. Products with such ingredients are classified in water hazard class 2 (WGK 2), ie as “clearly hazardous to water”.
- WGK 2 water hazard class 2
- alkalizing components thickened with a vinyl, acrylate or polyurethane polymer Another disadvantage of the alkalizing components thickened with a vinyl, acrylate or polyurethane polymer is that the gels can swell significantly after prolonged storage. This can occur if the consumer does not use up the entire application mixture of alkalizing component (M1), oxidizing agent preparation (M2) and possibly blond booster composition (M3) immediately, but instead keeps the remaining amount in the sealed mixing bottle for several days - contrary to the recommended instructions for use . This increases their volume, which inflates the storage bottles and, in the worst case, can burst.
- M1 alkalizing component
- M2 oxidizing agent preparation
- M3 possibly blond booster composition
- the present invention was therefore based on the objects of providing a thickened alkalizing component for an oxidative hair lightening agent
