Description

Compositions and methods for curly hair area of disclosure

The present disclosure relates to compositions for treating, conditioning and styling hair, as well as packaging systems and kits comprising the compositions, and methods of using the compositions.

CONTEXT

Many people are unhappy with the appearance of their hair and want to treat it to improve the look and/or feel. Consumers primarily use hair care products formulated for their hair texture and style and hope to achieve the desired result.

For example, consumers with curly hair may be concerned that their curly hair appears shorter than its actual length (shrinkage), and/or that the curls are not defined enough. People with curly hair may wish to maintain their curls and may also wish to achieve greater curl definition and/or evenness, and improve curl retention. Increasingly, consumers are also looking for hair products that look and feel natural, while providing good styling benefits to the hair. Consumers are also looking for products that offer multiple benefits, for example, combining frizz reduction and style hold with softening effects (i.e. not a "crunchy" feel), lengthening or enlarging while still providing good curl definition. Additionally, traditional hair lengthening, including straightening or straightening hair, often includes chemical treatment or high heat that can damage hair fibers and/or irritate the scalp.

As such, there is a need for new and improved products and processes for treating keratinous fibers, in particular human keratinous fibers such as curly or wavy hair, which can provide visible and/or lasting benefits in terms of defining and/or lengthening the curls, and/or maintaining the curls while achieving good definition and/or regularity of the curls, particularly in humid conditions, and at the same time imparting one or more various additional properties to the hair, such as better movement, good volume, frizz control, softness, smoothness, and/or natural shape, and which may be long-lasting, non-irritating, and/or non-toxic.

The present disclosure addresses these concerns and needs, and relates to hair treatment compositions that provide desirable defined and long-lasting curls to hair, which surprisingly can be achieved without the need for applying high heat, such as that of an iron, hairdryer or similar, and at the same time provide benefits such as improved curl definition, curl regularity and/or reduced shrinkage, and additional care and conditioning benefits , such as softness, frizz control, volume control and discipline.

The compositions may generally be applied to wet hair, but may also be applied to dry, damp or wet hair. In this document, the expression "effective amount" refers to a quantity sufficient to give the hair an effect of definition, regularity and/or lengthening of the curls, depending on the degree of curl, the length, the hair volume and texture. Typically, about 0.1 grams to about 50 grams of product is applied to the hair, depending on the specific product formulation, hair length, volume, and hairstyle type. In some embodiments, approximately 0.1 gram (g) of the composition per gram of hair is applied to the hair. In some embodiments, approximately 0.5 grams (g) of the composition per gram of hair is applied to the hair. The composition applied to the hair may be distributed throughout the hair as desired, preferably substantially evenly or uniformly by massaging the hair with fingers or a means such as a comb or the like.

After applying the composition to the hair, the hair can then be dried, for example in the open air or using a hair dryer. The composition may remain on the hair as a leave-in product for any necessary period, for example, from about a few seconds (e.g., 1, 3, 5, or 10 seconds) to about 10, 20, or 30 minutes, or more for a long time, for example a few hours or a few days, or until the next time you wash or rinse your hair. In some embodiments, compositions applied to the hair may remain on the hair to be air dried overnight prior to styling.

In some embodiments, the compositions are rinse-out compositions, meaning that they are intended to be left on the hair for a period of time to impart benefits, but are typically rinsed out before the hair is then dried and /or hairstyles. When the compositions are used as rinse-out compositions, the compositions are generally left on the hair for a certain time, for example at least a few seconds, for example about 30 seconds, or at least a few minutes, for example at least 5 minutes, before to rinse them. Therefore, in various methods according to the disclosure, the methods include a step of rinsing the composition from the hair.

In some embodiments, before applying the composition to the hair, the hair may first be cleansed with a commercially available shampoo or rinsed with water.

Example 4 - Evaluation of the synergy of citric acid and hydroxyethyl urea

Comparative studies were conducted to evaluate the synergy of citric acid and urea compounds in hair styling/treatment compositions.

Example 4A

A comparative test was carried out to evaluate the synergistic benefits provided by the combination of citric acid and hydroxyethyl urea as included in composition 2A according to the disclosure, in comparison with the comparative compositions C1 to C3 in Table 2.

Before applying the compositions, five strands of curly hair of the same type were prepared by conventional shampooing, conditioning with conventional conditioner and rinsing with water. Each of compositions 2A, C1, C2 and C3 was applied respectively to one of the prepared strands of hair, in an amount of approximately 0.1 gram of composition per gram of strand of hair and distributed evenly over the hair. The compositions were left on the hair and air dried overnight at room temperature. No composition was applied to a control strand after the shampoo/conditioner/rinse steps. Approximately 24 hours after application of the compositions, the control and treated hair strands were evaluated and images were taken.

There shows images of these five strands of hair 24 hours after treatment. As shown in the , hair treated with inventive composition 2A shows visibly improved curl definition and evenness, as well as curl retention, where curls are tighter and better held, compared to untreated control hair and hair treated with the comparative compositions C1, C2 or C3. Additionally, compared to hair treated with compositions C1, C2, or C3, hair treated with composition 2A visibly improved frizz control, manageability (e.g., no "flyaways"), manageability, and shaping, as well as better volume.

Example 4B

A comparative test was carried out to evaluate the synergistic benefits provided by the combination of citric acid and hydroxyethyl urea as included in composition 3A according to the disclosure, in comparison with the comparative compositions C4 to C6 in Table 3.

Before application of the compositions, four strands of curly hair of the same type were shampooed with a conventional shampoo, conditioned with a conventional conditioner and rinsed with water. Each of compositions 3A, C4, C5 and C6 was applied respectively to one of the prepared strands of hair, in an amount of approximately 0.1 gram of composition per gram of strand of hair and distributed evenly over the hair. The compositions were left on the hair and air dried overnight at room temperature. Approximately 24 hours after application of the compositions, the control and treated hair strands were evaluated and images were taken.

There shows the images of these hair strands 24 hours after application of the compositions. As shown in the , hair treated with inventive composition 3A surprisingly shows better curl definition and elongation, as well as better overall curl properties, compared to hair treated with comparative compositions C4, C5 or C6. Hair treated with Composition 3A is visibly longer, has visibly better curl retention and tighter curls, as well as improved smoothness, frizz control, manageability, discipline (e.g., no “flyaway hair”) and shaping compared to hair treated similarly with compositions C4, C5 or C6.

Examples 4A and 4B therefore demonstrate that the synergistic combination of citric acid and hydroxyethyl urea with a specific weight ratio, when combined with additional ingredients for styling and/or treating keratinous fibers, for example, a composed of silicone, fatty compounds, vegetable oils, cationic surfactants, polyols, and at an acidic pH, surprisingly and unexpectedly delivers significantly improved curl definition and lengthening, as well as other attributes such as curl hold, smoothness, frizz control and manageability of curly hair.

It will be apparent to those skilled in the art that various modifications and variations may be made to the compositions and methods according to the disclosure without departing from the spirit or scope of the disclosure. Thus, it is intended that the disclosure covers such modifications and variations and their equivalents.
