BACKGROUND OF THE INVENTION
The present invention refers to an oxidizing composition for the treatment of keratin fibers, the composition comprises a combination of:
(a) at least one anionic associative copolymer, (b) at least one anionic non-associative copolymer;
(c) at least one peroxide agent;
(d) at least one persulfate agent;
(e) at least one alkalizing agent; and (f) a suitable carrier medium for hair treatment.
Conventional hair treatments such as permanent dyeing, bleaching, and waving or straightening / straightening of keratin fibers, particularly human hair, always require an oxidizing composition.
Human hair mainly made up of α-keratins is an insoluble and robust structure. One of the reasons for the strength and stiffness conferred on the keratin fibers present in the hair is the presence of large amounts of disulfide bridges formed with sulfur-containing amino acid cysteine.
The current role of the oxidizing composition can be multiple depending on the type of treatment. In hair dyeing, the role of the oxidizing composition is to discolor the melanin pigment, to lighten the underlying hair color. But more important is its role in coupling the dye precursors together to form the color chromophores in the hair. For example, its main role in hair coloring is to oxidize the dye precursors, which after being "activated" allow the cascade of reactions that end with the formation of hair coloring. When used in hair bleaching, the oxidizing composition also has the role of gradually destroying the two natural pigments (eumelanins (dark brown black) and pheomelanins (reddish orange)) embedded throughout the cortex. The characteristic natural gradation of human hair color is the result of the combination of the ratio and concentration of these types of pigments. For example, while dark hair shows a higher concentration of eumelanins, red hair shows a predominance of pheomelanins. Slightly blonde hair has reduced amounts of both. Experience has further shown that when it is intended to destroy natural hair pigment, the oxidizing composition further destroys both eumelanin and pheomelanin, but at a different rate. Clearly, eumelanins have been found to be easier to break than pheomelanins. Due to these two different destruction rates, when bleaching dark hair it leads to an undesirable warm reddish orange or “metallic” hue due to increased red pigments. Finally, when used in bleaching hair, the oxidizing composition also has to bleach the previously deposited synthetic color that was already present in the hair.
When typically used as a dye precursor activator in a hair dyeing system, the oxidizing composition contains primarily a peroxide agent in a concentration ranging from 0.6% to 10% on the head by weight ratio.
In contrast, when used as a synthetic color buster and melamine, the oxidizing composition present in the final hair treatment mix would typically be supplied from a peroxide developer comprising a peroxide agent in a concentration ranging from 1.5% to 12.0%, by weight relative to the peroxide developer and a powdered bleach comprising a persulfate agent in a concentration ranging from 10.0% to 40.0% of active oxygen (S<sub>2</sub>OR<sub>8</sub><sup>2</sup>j by weight in relation to the bleach powder. Thus, the main concentration of the peroxide agent is typically 0.6% to 10% for the peroxide agent and 2.0% to 27% for the concentration of persulfate by weight relative to the oxidizing composition (i.e. after mixing the Powder bleach and peroxide developer in a ratio of
2: 1 to 1: 4).
Being highly chemically reactive, the oxidizing composition, in addition to the attributed role, may additionally have an impact on the carrier medium of the hair treatment composition, undergoing some undesirable side reactions. These reactions can have an impact on the different physical properties of the final hair treatment composition, such as consistency and homogeneity.
To be conveniently used by the consumer or styling professional, active agents, such as the oxidizing composition for hair treatment are included in a carrier medium comprising various components, such as polymers, surfactants, stabilizers, chelators and carriers. aqueous. These various additional components are important and necessary to obtain a composition that provides the desired benefit to the consumer, with the active ingredients but, in addition, that allows the consumer to use this composition conveniently without any danger.
The compounds known as "rheology modifiers" are crucial for any cosmetic composition, as they provide the necessary consistency for the composition, allowing the consumer to manipulate the composition and obtain the benefit. When exposed to an oxidizing environment, rheology modifiers have an additional challenge of having to be chemically and physically stable in these highly reactive environments.
A rheology modifier that enables the physical stability of an oxidizing composition to be maintained is described in US Pat. USA no. 7,070,769 B2, wherein a composition comprising "at least two anionic associative polymers" is described. In addition, the US patent. USA no. 6,547,833 B2 describes "a high aqueous developer formulation" for use in a two part composition for oxidative hair dye, the developer formulation comprises approximately 70% by weight of water, a peroxide oxidant and an acrylate / beheneth-25 methacrylate copolymer (Aculyn 28).
An object of the present invention is to provide an oxidizing composition suitable for the chemical treatment of keratinous material such as, for example, dyeing, discoloration, straightening and permanent waving of keratin fibers.
Among all the criteria required for a hair treatment composition, a very important criterion is obtaining the desired texture or consistency / rheology. This criterion is essential to allow the consumer an easy application of the hair treatment composition. To provide this easy application of hair treatment, compounds are used that provide a "thickening" benefit.
The main quality of a good rheology modifier is the ability to provide the desired consistency when preparing the final composition, during the treatment and until the end just before the consumer or styling professional removes the composition from the hair. As well as having the desired consistency / rheology during the preparation of the final composition, a highly desired rheology modifier would also maintain this consistency / rheology during the application of the composition on the hair, until the treatment process is complete.
Usually, the performance of the rheology modifier has been found to be highly correlated with the amount and type of oxidizing agent. As mentioned above, due to the high chemical reactivity of the oxidizing agent, there is a challenge to find effective rheology modifiers that provide this benefit throughout the period of hair treatment without a decrease in performance due to interactions with the oxidizing agent. present in the middle; that is, a great stability between all the components of the composition. Thus until now, the only way to overcome this problem of maintaining the same consistency / rheology was to stir the oxidizing composition continuously and vigorously during application. This is an inconvenience for the professional
Ί of the stylized and the consumer and results in an increase in the time required to apply the product to the hair.
Without being limited by theory, the logical explanation for the alteration of the rheology and consistency profile during use relates to the observed phenomenon of "Inflation" or "foam formation" or "thickened" behavior of a typical oxidizing composition after mixing of the components. This is believed to be related to the reactions that occur during mixing that tend to cause gas formation in situ, such as O<sub>2</sub> or CO<sub>2</sub>, which may be responsible for the swelling of the total composition. Gas bubbles trapped in the composition can be released by applying vigorous stirring to the composition.
This thickening behavior of the final composition is a disadvantage because it has an impact on the consistency of the final composition. Practically, having less compact and less dense properties, the composition would exhibit some difficulties for the consumer or styling professional when applying the composition to the hair. Therefore, a little of the oxidizing composition, when applied to consumer hair, would have a tendency to drip or slip from the hair, leading to more difficult application of the hair product. Much more critical are the swelling behaviors on the hair after application and during development time because the swelling behavior leads to expanded (swollen) aluminum packaging or uneven color effects on untreated hair when using techniques manuals.
Clearly, conventional theological modifiers, especially those involved in oxidizing compositions, tend to provide a long-lasting side effect when the components of said oxidizing composition comprise a persulfate agent, a peroxide agent, and alkalizing agents. Depending on the amount of alkaline persulfate agent, peroxide agent and alkalizing agents present in the oxidizing composition used in hair treatment, swelling of the oxidizing composition results. This foam formation phenomenon is particularly excessive in the case of highly oxidizing environments such as bleaching compositions.
Particularly, in the field of hair treatment using oxidizing compositions (i.e., bleaching, dyeing, perm or wicking / allatting of keratin fibers, particularly human hair) there remains a need for an effective rheological modifier, which is stable and inert towards the active principles as well as the other components of the oxidizing composition.
Just as stability is an essential characteristic of an acceptable rheology modifier, it is further desired to identify a rheology modifier that prevents the foaming behavior observed in oxidizing compositions and that overcomes the swelling behavior.
In the present invention an oxidizing composition is described, which as well as providing a highly desired property of maintaining the rheology of the composition during hair treatment, further provides an effective decrease in the swelling behavior of the oxidizing composition. Thus, the oxidizing composition of the present invention allows easy application of the composition to the hair and a very good adherence to the hair from the start of the application to the end of the hair treatment.
Now, it has been discovered that the specific combination of an anionic associative polymer and an anionic non-associative polymer that are used in an oxidizing environment, provide excellent rheological performance, chemical and physical stability, as well as an effective decrease in swelling behavior. undesirable observed in the oxidizing composition with other rheology modifiers. This specific combination has been found to provide excellent results, particularly with the so-called "Balayage" technology, where the hair color is painted directly onto sections of the hair without using aluminum to maintain color.

The pH is preferably adjusted with alkali metal or alkaline earth metal salts that are alkaline in an aqueous solution, allowing the final treatment of the hair to reach a pH in the range of about 8.5 to about 13, especially, about 9 to about 11.
Suitable alkali metal or alkaline earth metal salts are sodium carbonate, sodium hydrogen carbonate, magnesium carbonate, ammonium carbonate, ammonium hydrogen carbonate, sodium silicate and / or mixtures thereof; present in the powder bleach component in an amount of from about 5 to about 30% by weight of the powder bleach composition component, preferably from about 7 to 25% by weight.
The powder bleach may further comprise additional adjuvant (s). In one embodiment, the powder bleach may comprise a colorant selected from the group consisting of water-insoluble pigments or lacquers and mixtures thereof (hereafter "pigment"), generally in an amount up to 2.5% by weight of the bleach powder, preferably 0.1% to 2% by weight. The pigment must be compatible with other ingredients in the oxidizing composition and in particular must be compatible with the peroxide agent. Pigments only color the oxidizing composition. Suitable pigments include Ultramarine Blue, D&A Aluminum Lacquer. 10 C yellow, chrome oxide green, lacquer no. 30 red D and C, and zirconium lacquer no. 5 yellow D and C.
In addition, a desiccant such as silica is typically incorporated to prevent moisture from premature reaction with persulfates. Silica in a positive amount, generally less than 5% by weight, usually 0.01% to 3% by weight of the powder bleach. Additionally, silica acts as a lubricant to aid in dry mixing of powdered materials.
In addition to the components previously described in the present description, the powder bleach may comprise additional ingredients to facilitate its use and performance. Thus, the powder bleach composition may further comprise one or more of the following adjuvants: additional rheology modifiers (eg, cellulose and starches), emulsifier, stabilizing and / or chelating agents, dedusting agents, conditioning agent , fragrance and / or tints.
Each of these adjuvant constituents are present in the powder bleach in an amount sufficient to provide its intended function in the powder bleach or in the final product mixture when mixed with the peroxide developer.

The powder bleach component is preferably contained in an aluminum sachet package, the entire contents of which are emptied by the consumer into the developer component container.
The oxidizing composition applied to the hair preferably has a viscosity of 20,000 to 60,000 cps, preferably of 30,000 to 45,000 cps. The product remains on the hair until the desired clarification of the hair is achieved. Generally, this time period is less than about 60 minutes.
The proportions of the three components used in the process are tailored so that there is no excess of the product or residual components of the product remain after use. Proportions are predetermined so that mixing the six components (a), (b), (c), (d), (e) and (f) achieves the correct consistency of the product and the desired concentration of ingredients actives, as well as the adjuvants contained separately in the final mixture composition and, therefore, the pH of the final product is from about 8.5 to 13, preferably from about 9 to about 11.
Method of use
As described above, the powder bleach composition is added from its package in the peroxide developer, preferably in the applicator package. The contents are then mixed by stirring. Using the applicator tip, the final composition of the bleaching product is applied to the hair in a conventional manner. The degree of clarification is checked periodically, and when the desired level of clarification is typically obtained in less than 60 minutes even for black hair, the product is rinsed from the hair and the hair is preferably shampooed and dried . A conditioner can be applied to your hair right after rinsing, which can also be included in the kit.
For professional styling use, powder bleach and peroxide developer will be provided in larger quantities, eg. For example, a 1000 g container of powder bleach and / or a 1000 ml bottle of peroxide developer. The ready-to-use oxidizing composition will be mixed, directly, before use by a styling professional in a container or applicator bottle. The mixing ratio of powder bleach to peroxide developer can be 2: 1 to 1: 4.
The oxidizing composition will be applied to the hair using the applicator bottle or brush. It can be used on the whole head or partially only on strands (light application). It can be commonly used as aluminum foil, hats or special light applicators, but it is also possible with manual techniques such as balayage, with a brush and / or comb.

conclusion
From the above data, it can be seen that the mixtures containing developer D show a high structural resistance. They show a higher plateau value with both bleaches. The end of this plateau is defined by a 10% drop from the first value (to 0.4% voltage). They show a constant storage modulus value up to ~ 1.5% voltage. In this plateau region, the hair bleach mixture does not significantly change the structure and provides a constant vlascoelastic response. The end of the plateau value describes the exposure of the tension needed to destroy the structure of the gel network. Accordingly, blends containing developer D will tend to reduce dripping, reduce the tendency of the oxidizing composition to dry on the hair during application and / or on the brush during transfer of the container to the hair.

It is estimated that for the application speed in use with the Balayage technique the Frequency Interval ~ 5 - ~ 50 [1 / s] is equivalent. Mixtures containing developer D show a significantly smaller loss factor [tan δ] over the Frequency range ~ 5 - ~ 50 [1 / s]. Therefore, they have a better elastic behavior over the entire frequency range, that is, the mixtures have a greater adherent character.

conclusion
The mixtures containing developer D show a significantly higher complex modulus [G '] over the frequency range ~ 5 -50 [1 / s]. Therefore, they show a more rigid material characteristic. Consequently, these mixtures provide a better brush application on the hair since the adhesive / adherent ratio improves the stickiness to the hair during application.
Volume results increase: See table below and Figure 3a & b
Procedure description:
A certain amount of powder bleach and peroxide developer are mixed in a glass (diameter: 60mm). At start (start) t = 0, the beaker was filled with a product with a 1: 3 combination ratio of bleaching and developer composition, respectively. The surface of the glass was marked where the surface of the product ended. A measurement is made by using a ruler from the bottom of the glass to where the surface of the product ended. This measurement is made in mm by using a ruler.
Thereafter, the volume increase was marked every 10 min up to 1 hour. The evolution of the volume increase was then measured in 10, 20 ... 60 min in mm.

As shown above, the performance of developer D has been tested first with Powder Bleach 1 and then with Powder Bleach 2. In both cases, Developer D showed less volume when compared to Developer A, B, or D.
General conclusion:
Practically, the reduced swelling of the described oxidizing composition is convenient for the consumer and / or professional of the styling. For example, when used to illuminate partial sections of hair; After the application of said oxidizing composition, due to the reduced swelling effect, the hair will provide high lighting results in specific areas where the composition has been applied. This will avoid staining the sections of hair that you do not want to treat but that are close to the section of hair where the oxidizing composition has been applied.
The dimensions and values described in the present description should not be interpreted as strictly limited to the exact numerical values mentioned. Instead, unless otherwise specified, each of those dimensions will mean both the mentioned value and also a functionally equivalent range comprising that value. For example, a dimension described as "40mm" refers to "about 40mm".
