COMPOSITIONS FOR SHAPING OR ALTERING THE SHAPE OF HAIR

FIELD OF THE INVENTION

[0001] The present application relates to hair cosmetic compositions for use on keratinous substrates. In particular, it relates to compositions and methods for shaping or altering the shape of hair, such as by relaxing or straightening hair.

BACKGROUND OF THE INVENTION

[0002] Cosmetic and personal care products for use on keratinous substrates such as skin and hair are designed to achieve and provide certain benefits and attributes such as efficaciousness, cosmeticity, desirable texture, stable formulations, and ease and convenience of use and application. Thus, in order to meet changing consumer needs and preferences, manufacturers of such products continuously seek to re-formulate and create new products with enhanced efficacy, while still remaining safe to use, as well as improve the manufacture, transport, and storage of these products. In addition, manufacturers continue to test the use of new raw materials and ingredients or new product forms that would help deliver the desired attributes and properties. However, in doing so, formulation challenges are often encountered. For example, re-formulating existing products may adversely impact certain product attributes and properties such as viscosity, texture, stability and efficacy.

[0003] One area where manufacturers are always seeking to provide improved consumer and cosmetic products is in the area of styling or altering the configuration/shape of hair such as hair on human heads. There are many techniques and compositions for styling or altering the appearance and shape of hair. In today's market, there is an increasing demand for the hair care products referred to as "hair relaxers" or "hair straighteners" which can relax or straighten curly or kinky hair, including wavy hair. Straightening or relaxing the curls of very curly hair may increase the manageability and ease of styling of such hair. Hair relaxers may either be applied in a hair salon by a professional or in the home by the individual consumer.

[0004] One type of composition that can be applied onto hair in order to change its shape and make it more manageable is an alkaline composition. Alkaline hair relaxing/straightening consists of hydrolysis of the keratin of the hair with various alkaline agents, such as inorganic hydroxides, for instance sodium hydroxide, or organic hydroxides, such as guanidine hydroxide, or organic amines. Hair relaxing/straightening products that employ sodium hydroxide or potassium hydroxide are also called lye-based products and products that use other alkaline agents such as lithium hydroxide, organic hydroxides and other non-hydroxide compounds, for example, organic amines, generally fall under the category of no-lye products. Lye-based products are generally employed as one-component systems ("no mix" systems).

[0005] One other type of product based on a no-lye composition employs guanidine hydroxide as the active agent for straightening or relaxing hair. Guanidine hydroxide is unstable and therefore, most commercial products of this type are based on a two-component system ("mix" system) containing a composition comprising a hydroxide-based compound such as calcium hydroxide and a second composition comprising a carbonate compound such as guanidine carbonate. The two compositions are mixed prior to relaxing or straightening the hair in order to produce guanidine hydroxide in the resulting mixture or ready to use composition.

[0006] Generally, alkaline hair relaxing/straightening products can be made available in liquid, lotion or cream form in order to facilitate their application onto hair. Thus, hair relaxing and straightening products should have a viscosity such that they do not run or drip when applied onto the hair fibers so as to avoid contacting the skin with the product and to ensure the deposition of the alkaline agents onto the hair fibers. The process of treating hair with the above-described relaxing/straightening products may also include heating and/or physically changing the shape of the hair by use of a brush or a comb.

[0007] Still, it is desirable to find alternatives and/or improvements to the alkaline lye- and no-lye-based products and process described above which may damage to the hair by weakening and/or causing dryness of the hair fibers. However, the discovery of new compositions and processes for changing the shape of hair may pose challenges to manufacturers and formulators because the incorporation of new ingredients into the compositions may negatively impact their performance, cosmetic attributes, and formulation stability. New processes of treating and changing the shape of hair may also impact the performance of the compositions, processing times and quality of use. [0008] Attributes of products for treating hair that can affect their performance and/or desirability to consumers include texture, form or appearance (liquid, cream, gel, lotion or powder), ease of application, viscosity or rheology, ease of use, storage, effect on the quality and feel of the hair, and safety. For example, hair relaxing and straightening products should have a viscosity such that they do not have a thin consistency. This means that they should not run or drip readily when applied onto the hair fibers so as to avoid contacting the skin with the product and to ensure that the active or straightening agents in the product are deposited onto the hair fibers and remain on the fibers during the straightening/relaxation period.

[0009] The present invention provides a hair treatment agent comprising a composition ("composition (A)") containing an alkaline material selected from at least one hydroxide-containing compound and at least one carbonate compound, a cationic polymer selected from at least one quaternary diammonium polycondensate, an amphoteric polymer selected from at least one quaternary ammonium compound, an organic solvent, and water; wherein the pH of the composition is equal to or greater than 12 and wherein the weight ratio of (b) to (c) ranges from about 1 up to about 3. The hair treatment agent can further comprise an activator component. Depending on the selection of the alkaline material, the activator component can contain a hydroxide-containing compound or a carbonate compound. The agent can also optionally contain a non-alkoxylated fatty substance that is liquid at room temperature, and/or an alkoxylated nonionic surfactant, and/or a fatty alcohol that is solid at room temperature. It has now been surprisingly and unexpectedly discovered that said agent can be used to shape or alter the shape of hair such as by relaxing or straightening hair.

[0010] It was also surprisingly and unexpectedly discovered that the composition (A) of the present invention is stable, i.e., there is no phase separation, even when cationic and amphoteric polymers are employed in a high-pH composition. In addition, composition (A) and/or hair treatment agent have a viscosity their corresponds to a non-drip, and homogeneous consistency that facilitates the ease of application onto hair fibers, thereby resulting in an effective process of shaping or altering the shape of hair.

AGENTS AND HAIR TREATMENT COMPOSITIONS FOR SHAPING OR ALTERING THE SHAPE OF HAIR

[00190] According the present invention, the agent for shaping or altering the shape of hair comprises a hair treatment composition containing an alkaline material selected from hydroxide-containing compounds and carbonate compounds, a cationic polymer selected from at least one quaternary diammonium polycondensate, amphoteric polymer selected from at least one quaternary ammonium compound, an organic solvent, and water, wherein the weight ratio of (b) to (c) ranges from about 1 up to about 3. Optionally, said agent can further comprise an activator component. In certain embodiments, the activator component comprises: (i) at least one hydroxide-containing compound or at least one carbonate compound, and optionally, (ii) a solvent.

[00191] In certain embodiments, the amount of the solvent in the activator component is in an amount of at least about 50% by weight, or of about 60% by weight, or of about 70% by weight, or of about 75% by weight, or of about 80% by weight, based on the weight of the activator component.

[00192] In other embodiments, the activator component is essentially free of water and is in powder form.

[00193] The agent for shaping or altering the shape of hair may comprise a one- component system ("no mix" system) or a two-component system ("mix" system). In a no mix system, the activator component of the present invention is not employed in the agent for shaping or altering the shape of hair. In a mix system, the activator component of the present invention is employed in said agent.

[00194] Thus, in one embodiment, the agent for shaping or altering the shape of hair is a no mix system wherein the alkaline material in the hair treatment composition is at least one hydroxide-containing compound selected from alkali metal hydroxides, alkaline-earth metal hydroxides, transition metal hydroxides, and mixtures thereof and the alkaline material is not selected from a carbonate compound. In said no mix system, the activator component is not employed or required.

[00195] In another embodiment, the agent for shaping or altering the shape of hair is a mix system ("mix system I") wherein the alkaline material in the hair treatment composition is at least one carbonate compound selected from lithium carbonate, sodium carbonate, potassium carbonate, guanidine carbonate, and mixtures thereof and the alkaline material is not selected from a hydroxide-containing compound. Preferably, the carbonate compound is selected from guanidine carbonate. In said mix system I, the activator component is employed and comprises at least one hydroxide-containing compound selected from alkali metal hydroxides, alkaline-earth metal hydroxides, transition metal hydroxides, and mixtures thereof. Preferably, the hydroxide-containing compound of the activator component is calcium hydroxide.

[00196] In yet another embodiment, the agent for shaping or altering the shape of hair is a mix system ("mix system II") wherein the alkaline material in the hair treatment composition is at least one hydroxide-containing compound selected from alkali metal hydroxides, alkaline-earth metal hydroxides, transition metal hydroxides, and mixtures thereof. Preferably, the hydroxide-containing compound of the activator component is calcium hydroxide. In said mix system II, the activator component is employed and comprises at least one carbonate compound selected from lithium carbonate, sodium carbonate, potassium carbonate, guanidine carbonate, and mixtures thereof and the alkaline material is not selected from a hydroxide-containing compound. Preferably, the carbonate compound is selected from guanidine carbonate.

[00197] In both mix systems I and II, the hair treatment composition is capable of being combined with the activator component, resulting in the formation of a mixture or composition (also called ready to use composition) which is applied onto hair. The combination of the hair treatment compositions and the activator component results in the formation of guanidine hydroxide due to the reaction between the alkaline material in the hair treatment compositions and the hydroxide-containing compound or the carbonate compound in the activator component. The guanidine hydroxide serves as the active material for straightening or relaxing hair.

[00198] In preferred embodiments of the present invention, the agent for shaping or altering the shape of hair comprising the hair treatment composition or the combination of the hair treatment composition and the activator component is a composition for straightening or relaxing hair.

[00199] The activator component may be separately packaged from the hair treatment composition of the invention and mixed with said composition right before use on hair in order to shape or alter the shape of hair, for example, by straightening or relaxing the hair. [00200] The activator component of the present invention may be mixed with varying amounts of the hair treatment composition of the present invention to obtain a ready to use composition with properties suitable for a particular use or to suit different types of hair and/or to achieve different degrees of hair relaxation or straightening

[00201] In some embodiments, the activator component is combined with the hair treatment composition in a weight ratio of from about 10: 1 to about 1 : 10, or from about 1 :3 to about 1 : 10, or from about 3: 1 to about 1 : 10, or from about 1 :3 to about 1 :5, or from about 3: 1 to about 1 :5, or at about 1 :3, or at about 1 :4, in order to form a ready to use composition.

[00202] The term "combined" and all variations of this term as used herein refers to contacting or mixing or reconstituting or dissolving or dispersing or blending or shaking the activator component with the hair treatment composition. It can also mean introducing the activator component to the hair treatment composition. It may also mean placing the activator component in the same vessel or container as the hair treatment composition.

[00203] The step of contacting the activator component composition with the hair treatment composition can be conducted in any vessel suitable for holding the resulting ready to use composition.

[00204] The term "ready to use composition" as used herein refers to the composition resulting from mixing the activator component and the hair treatment composition of the invention. Generally, the ready to use composition is to be prepared by the consumer or hair dresser on the day that the hair is to be straightened or relaxed. It can be applied onto hair immediately after it is prepared. There could also be a certain period of time before the ready to use composition is applied onto hair from the time of preparation of said composition, such as from between about 2 minutes to about 60 minutes, or such as from between about 2 minutes to about 30 minutes.

[00207] The pH of the hair treatment composition or agents of the present invention may be adjusted to the desired value using conventional acidifying or basifying agents.

[00208] The pH of all numbers expressing pH values are to be understood as being modified in all instances by the term "about" which encompasses up to +/- 1 % of the indicated pH value (e.g. "about 12.2" means 12.125 - 12.32% and "about 2%" means 1 .8% - 2.2%).

[00235] The relaxing or straightening effects obtained using the compositions and processes of the present disclosure may also be durable or long lasting.

[00236] The degree of straightening or relaxing the hair may be evaluated by visually assessing the reduction in curliness and/or waviness and/or frizziness of the hair after contacting the hair with the composition of the invention. Another type of evaluation can also involve measuring the length of the hair as well as the width of the bulk of hair before and after contacting the hair with the composition of the present invention.

[00237] It was surprisingly and unexpectedly discovered that the hair contacted with the compositions of the invention did not feel rough and visually appeared to be smooth, extended and straight.

[00238] As used herein, the method and composition disclosed herein may be used on the hair that has not been artificially dyed, pigmented or permed. [00239] As used herein, the method and composition disclosed herein may be also used on the hair that has been artificially dyed, pigmented or permed.

[00240] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective measurements.

In comparison to the comparative compositions, the inventive compositions were preferred for product consistency (thick, cream texture), wet combing, mass effect of dry hair and wet hair smoothness in tests on hair on heads of human volunteers.

EXAMPLE 2 - Stability of Inventive Compositions The inventive compositions were shown to be stable up to 8 weeks in a controlled chamber at various temperatures at 5°C, 25°C, 37°C, and 45°C as well as 10 days in a Freeze/Thaw cycle where the pH and viscosity had small fluctuations and there was no phase separation.

EXAMPLE 3 - Salon testing

The inventive and comparative compositions were tested on the hair on heads of human volunteers in half-head studies (salon test) by applying the test compositions on the hair evenly and leaving them on the hair for a period of time. The compositions were then rinsed off the hair with water. The hair was then contacted and cleansed with a neutral shampoo and rinsed well with water. The hair was styled as desired.

EXAMPLE 4 - Wet combing experiments on hair swatches to test various polymers The wet combing studies were conducted on hair swatches as follows:

1 . Aqueous solutions at pH 13.5 to 13.7 containing 0.5% by weight of active material of the following polymers were prepared: These solutions contained water, the test raw materials and sodium hydroxide in an amount needed to reach the desired pH of 13.5-13.7. a. No polymer (Control solution at same pH)

b. Hexadimethrine chloride

c. Polyquaternium- 6

d. Polyquaternium-7

e. Polyquaternium-22

f. Polyquaternium-47

g- Hexadimethrine chloride + Polyquaternium-22

h. Hexadimethrine chloride + Polyquaternium-6

Hair swatches were prepared with a length of 7 cm and weight of

0.25 grams each.

3. Hair swatches were immersed in the solutions for 15 minutes.

4. The swatches were then washed twice with 10% ALS solution.

5. The swatches were combed 20 times prior to testing.

6. Swatches were then dipped 3 times in water, with excess water removed by running the hair sample through the operator's fingertips.

7. The samples were then secured and combed with a wet combing

instrument device.

8. The above procedure was repeated 10 times per swatch.

The wet combing instrument measured: (1 ) the peak combing force required to comb the swatch which primarily translates to the force required to detangle the hair and (2) the work of combing required to pass the comb through the swatch; when the force measured is plotted against the distance by which the comb was moved through the hair, the area under the curve corresponds to the wet combing force. This translates to the overall conditioning of the hair. Figure 1 shows a sample combing profile.

From the results above, for trial one, it was unexpectedly and surprisingly found that the treatment of the hair with solutions containing hexadimethrine chloride alone and the combination of hexadimethrine chloride and Polyquaternium-22 resulted in greatly reduced peak combing forces and reduced wet combing forces, indicating a substantial/significant effect on the surface of the fibers. The results for the combination of hexadimethrine chloride + Polyquaternium-22 were significantly different from those obtained with the control. The forces for polyquaternium-22 alone were higher compared to those obtained for hexadimethrine chloride alone and either comparable to or greater than those obtained for the combination of hexadimethrine chloride and Polyquaternium-22. The results for another type of polyquaternium compound, polyquaternium-6 (non-amphoteric), resulted in wet combing forces that were comparable to those for the controls and higher than those obtained for hexadimethrine chloride + Polyquaternium-22 combination (invention).

It appears that the addition of polyquaternium-22 to hexadimethrine chloride did not adversely affect the wet combing performance of hexadimethrine chloride. While the measured forces on the hair treated with the solution containing the combination of hexadimethrine chloride and polyquaternium-22 could be comparable to the forces measured with the hair treated with the solutions containing hexadimethrine chloride alone and to Polyquaternium-22 alone, when formulas with hexadimethrine chloride alone were tested against the formulas containing the combination of hexadimethnne chloride and polyquaternium-22 in a salon test, there was a noticeable difference in scalp comfort wherein more scalp irritation with hexadimethnne chloride only was observed. Thus, the presence of polyquaternium-22 results in the reduction or minimization of scalp irritation attributed to the use of an alkaline solution. There were also differences observed with respect to wet combing, dry hair suppleness, ease of shaping with an iron and volunteer preference favoring the inventive formula, as well as in smoothness and tactile feel in favor of the inventive formula.

It is to be understood that the foregoing describes preferred embodiments of the invention and that modifications may be made therein without departing from the spirit or scope of the invention as set forth in the claims.
