Description

HAIR TREATMENT COMPOSITION FIELD OF DISCLOSURE

The present disclosure relates to hair treatment compositions and methods for treating hair with the hair treatment compositions.

CONTEXT

Many consumers wish to use cosmetic and care compositions which enhance the appearance of keratinous substrates such as hair, for example by modifying the color, style and/or shape of the hair, and/or by imparting various cosmetic properties to the hair. hair, such as shine and conditioning. Hair can become dry or damaged for a variety of reasons, for example exposure to weather, poor diet, mechanical treatments (e.g. brushing hair), styling treatments using chemicals, dyeing, heat, food, etc. Even cleansing products can strip the hair's natural oils, causing dryness that can lead to dullness and split ends.

Chemical treatments include, for example, hair bleaching and coloring, perms, waving products and relaxer treatments (straightening treatments). These chemical treatments alter the appearance of hair by changing its physical structure, which inevitably causes some degree of damage to the hair. Environmental factors, such as salt water, sun, and heat, are also known to damage hair. Damaged hair is characterized by unnatural changes in the protein structure of individual hair strands or shafts. The damage results in split ends, dry straw-like hair, hair that breaks easily, and hair that is “frizzy” and unmanageable. The visible portion of the hair being dead, it does not have the capacity to regenerate. There are many over-the-counter and salon treatments that claim to repair damaged hair. They include conditioners, hot oil treatments, hydrolyzed proteins, vitamin formulations and exotic fruit, leaf or root extracts. However, these treatments only provide limited improvement to the hair. This is why we are looking for hair repair technologies that can restore hair properties to their natural level.

The popularity and use of oils for treating dry hair has increased due to their effectiveness and simplicity. Commonly used oils include olive oil, mineral oil, avocado oil, apricot kernel oil, rice bran oil, and coconut oil. However, these treatments can leave hair feeling greasy. Furthermore, the effects are usually not visible after more than several hours (e.g. 8 hours) of treatment and multiple treatments are usually required, making the treatment time-consuming and laborious.

There is still a need to provide improved hair manageability, for example, improved hair alignment, reduction of unwanted volume (including reduced frizz) and increased shine. There is also a need to develop hair care products that can provide other benefits at the same time, in addition to the care and conditioning benefits, such as styling, volume, shaping and defining curls. (for curly or wavy hair).

DISCLOSURE SUMMARY

The present disclosure relates to hair treatment compositions and methods that provide beneficial effects to hair. For example, hair treatment compositions improve cosmetic attributes such as softness, shine, conditioning and healthy appearance. Hair treatment compositions include cationic polymers and nonionic polymers; and include citric acid, a salt thereof, or a combination thereof. The inventors have discovered that the ratio of cationic polymers to nonionic polymers and citric acid, a salt thereof, or a combination thereof influences the stability and desirable cosmetic properties of the compositions.

Hair treatment compositions typically include:

(a) one or more fatty alcohols;

(b) one or more cationic surfactants;

The weight ratio of (c) cationic polymer(s) to (d) nonionic polymer(s) is typically about 2.9:1 to 1:2.9. Additionally, the pH of the composition is typically about 3 to about 6.

Silicones may optionally be included in the hair treatment compositions, but preferably the compositions are free or substantially free of silicones. Silicones are synthetic polymers made up of repeating elements of siloxane, silicon and oxygen, combined with other elements, most often carbon and hydrogen. Thus, silicones are also called polysiloxanes. In some cases, the hair treatment compositions herein may be free or essentially free of dimethicones, amodimethicones, dimethiconols, cyclosiloxanes, siloxanes, etc.

Hair treatment compositions are aqueous compositions and are typically in the form of an oil-in-water emulsion. Fatty alcohols and optionally other fats (called "fatty compounds") mainly form the fatty phase of the emulsion. The aqueous phase consists of water and may optionally include one or more water-soluble solvents. The compositions typically include high amounts of water, for example, at least 50% by weight, preferably at least 60% by weight, and more preferably at least 65% by weight.

The hair treatment composition may remain on the hair prior to rinsing for a period of time of at least 5 minutes, for example from at least 5 minutes to about 15 minutes.

In some embodiments, the hair treatment compositions of the present disclosure may be used as a leave-in product, i.e., a product that is applied to the hair before and/or during hair styling and which remains on the hair after styling the hair. The leave-in product can be applied to wet, damp or dry hair after shampooing and optionally conditioning hair. The leave-in product can also be applied to wet, damp or dry hair, regardless of shampoo and/or conditioner.

In some embodiments, the hair treatment compositions of the present disclosure are particularly useful in conjunction with chemical hair treatments. For example, hair treatment compositions may be applied to chemically treated hair as a rinse-out or leave-in product. Likewise, the hair treatment compositions can be used as a pre-treatment or post-treatment before or after a chemical treatment of the hair, that is to say before or after the treatment of the hair with chemically reactive products such as the compositions oxidizing hair coloring/lightening agents and hair straightening and/or straightening compositions.

Hair treatment methods, according to the methods discussed above, are useful for conditioning hair. The methods are also useful in methods of improving the natural look and feel of hair, reducing frizz, improving hair softness, alignment and/or shine. The methods also relate to increasing the hydrophobicity of hair.

Stability

The hair treatment compositions are stable and homogeneous. In other words, the hair treatment compositions do not visually phase separate or develop sedimentation, nor do they form visibly observable particles. As shown in the example below, the hair treatment composition remained stable throughout the duration of the test. For example, the hair treatment composition remained stable for at least 1 week at room temperature; the hair treatment composition remained stable for at least 8 weeks at 4°C; the hair treatment composition remained stable for at least 8 weeks at 45°C. Therefore, the present disclosure relates to hair treatment compositions that remain visually homogeneous and free of visual phase separation and particle formation for at least one week at room temperature. Additionally, the present disclosure relates to hair treatment compositions that remain visually homogeneous and free of visual phase separation and particle formation for at least 8 weeks at 4°C. The present disclosure also relates to hair treatment compositions that remain visually homogeneous and free of visual phase separation and particle formation for at least 8 weeks at 45°C.

Processes

The present disclosure relates to methods of treating hair. The methods include applying a hair treatment composition according to the present disclosure to the hair and then rinsing the hair treatment composition. Hair treatment compositions may be used, for example, as a conditioning composition or conditioning mask that is applied to the hair before or after shampooing the hair; or they can be used as a conditioning composition that is used without shampooing the hair. Typically, the hair treatment composition is applied to wet or damp hair, massaged into/through the hair, and then rinsed from the hair before drying and/or optionally styling the hair. The hair treatment composition may be left on the hair before rinsing for a period of time, for example a period of time of about 10 seconds to about 10 minutes, before rinsing the hair. The hair treatment composition can stay on the hair for about 10 seconds to about 5 minutes, about 10 seconds to about 2 minutes, about 30 seconds to about 10 minutes, about 30 seconds to about 5 minutes, about 30 seconds to about 2 minutes, about 1 minute to about 10 minutes, about 1 minute to about 5 minutes, or about 1 minute to about 2 minutes, including any combination, sub-combination, range or sub-range thereof.

Hair treatment methods, according to the methods discussed above, are useful for conditioning hair. The methods are also useful in methods of improving the natural look and feel of hair, reducing frizz, improving hair softness, alignment and/or shine. The methods also relate to increasing the hydrophobicity of hair. Thus, the present disclosure relates to methods for: (a) conditioning hair; (b) improve the look and feel of hair; (c) reduce frizz or the propensity to curl; (d) improve hair softness; (e) improve hair alignment; (f) improve or increase shine of hair; the method comprising applying to the hair a hair treatment composition according to the present disclosure.

Accordingly, the hair treatment composition may include a greater total amount of the (a) fatty alcohol(s) than the total amount of the (b) cationic surfactant(s); a higher total quantity of the (a) fatty alcohol(s) than the total quantity of the (c) cationic polymer(s); a higher total quantity of the (a) fatty alcohol(s) than the total quantity of the (d) nonionic polymer(s); a higher total quantity of the fatty alcohol(s) than the total quantity of citric acid, its salt, and/or its combination (e); a higher total quantity of the (a) fatty alcohol(s) than the total quantity of the fatty compound(s) other than (g) fatty alcohols; a higher total quantity of the (a) fatty alcohol(s) than the total quantity of the water-soluble solvent(s) (h); a higher total quantity of the fatty alcohol(s) (a) than the total quantity of the nonionic surfactant(s) (i).

In the above embodiment, the hair treatment compositions may have a higher total amount of one or more fatty alcohols (a) than the total combined weight percentage of one or more cationic surfactants (b) and d one or more nonionic surfactants (i). Additionally, in some cases, the hair treatment composition may have a greater total amount of one or more fatty alcohols (a) than the total combined weight percentage of one or more cationic surfactants (b), a or more nonionic surfactants (i), and any other additional surfactants which may optionally be present, for example, amphoteric/zwitterionic surfactants.

In the above embodiment, the weight ratio of the total amount of the fatty alcohol(s) (a) to the cationic surfactant(s) (b) is at least 1.5:1 ((a): (b) )). Furthermore, the weight ratio of the total amount of one or more fatty alcohols (a) to the cationic surfactant(s) (b) may be at least 1.8:1, 1.9:1, 2:1 , 2.1:1 or 2.2:1 ((a): (b)). Thus, the ratio (a): (b) can be from 1.8:1 to about 5:1, about 1.9:1 to about 5:1, about 2:1 to about 5:1, about 2, 1:1 to approximately 5:1, approximately 2.2:1 to approximately 5:1, approximately 2. 2:1 to approximately 5:1, approximately 1.8:1 to approximately 4:1, approximately 1.9: 1 to approximately 4:1, approximately 2:1 to approximately 4:1, approximately 2.1:1 to approximately 4:1, approximately 2.2:1 to approximately 4:1, approximately 2. 2:1 to approximately 4 :1, approximately 1.8:1 to approximately 3:1, approximately 1.9:1 to approximately 3:1, approximately 2:1 to approximately 3:1, approximately 2.1:1 to approximately 3:1, approximately 2.2:1 to approximately 3:1, approximately 2.2:1 to approximately 3:1, including any combination, sub-combination, range or sub-range thereof by weight, based on the total weight of hair treatment composition.

Example 3 (Stability data)

The compositions of Example 2 were subjected to stability studies. The stability of the compositions was estimated visually during the initial manufacture of the composition (T ₀ ). The compositions were evaluated again after one week of freeze-thaw testing (1W FT). The compositions were placed in a stability chamber and subjected to temperature fluctuations at 12 hour intervals. For 12 hours, the compositions were held at -10°C. For the next 12 hours, the compositions were held at 25°C. The cycle was repeated 7 times (for 1 week). The compositions were evaluated separately after 8 weeks of storage at 4°C (8W 45°C), and after 8 weeks of storage at 45°C (8W 4°C). The results are presented in the table below.

As shown above, inventive composition A was stable under all test conditions. None of the comparative compositions were stable under all test conditions, with the exception of comparative composition C-7.

Example 4 (Sensory data)

The compositions of Example 2 which were at least initially stable were tested to determine their benefits for hair. Strands of heavily bleached Caucasian hair (SA40, 2.7 g, 27 cm) were used for testing. Equal amounts of each composition tested (approximately 1.2 grams) were applied to damp strands of hair, massaged into the hair and left on the hair for 5 minutes. After 5 minutes, the compositions were rinsed from the hair strands with tap water at room temperature. After removing excess water from the hair strands, they were washed with a standard base shampoo. After washing, the strands were first towel-dried and then completely dried using a hairdryer. Throughout this process, the expert evaluators tested the hair strands for various sensory effects: wet softness, wet combing, dry softness, dry combing, dry strength and dry alignment. Specifically, raters determined whether the sensory effects were better than the reference (inventive composition A), worse than the reference, or substantially the same as the reference. The results are presented in the table below.

* B = Reference (inventive)

** NA = not evaluated due to the instability of the composition produced

++ Better than the reference

+ A little better than the reference

= Same as reference

- A little lower than the reference

-- Lower than the reference

Inventive composition A gave the most balanced performance on dry and wet hair, that is to say it gave the best results on all the attributes tested. All comparative compositions failed to provide a full spectrum of improvements. For example, comparative composition C7 showed improvements in dry strength and combing, but resulted in significant reductions in dry strength and alignment. Inferiority in dry alignment makes the hair appear dry and weakened, which is unfavorable to consumers. The complete and balanced nature of the various attributes provided to the hair by the inventive composition A is significantly and surprisingly superior to that provided by the comparative compositions.

Definitions

As used herein, the terms “comprising”, “having” and “including” (or “include”, “have” and “include”) are used in their open and non-limiting sense. The phrase “consisting essentially of” limits the scope of a claim to those matters or steps specified and those which do not materially affect the fundamental and novel features of the claimed invention.

The terms “un”, “une” and “le”, “la” are understood to include the plural and the singular. Thus, the term “a mixture of” is interchangeable with “mixtures of”. Throughout the disclosure, the phrase "a mixture thereof" is used, after a list of elements as shown in the following example where the letters A through F represent the elements: "one or more selected elements in the group consisting of A, B, C, D, E, F, or mixtures thereof. The phrase "a mixture thereof" does not require that the mixture include all elements A, B, C, D, E and F (although all elements A, B, C, D, E and F may be included). Rather, it indicates that a mixture of two or more of elements A, B, C, D, E and F may be included. In other words, it is equivalent to the expression "one or more elements chosen from A, B, C, D, E, F, and a mixture of any two or more elements from A, B, C, D, E and F.”

Likewise, the term "a salt thereof" also refers to "salts thereof". Thus, when the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, or mixtures thereof," it indicates that a or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included.

Salts mentioned throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal or ammonium counterion. This list of counterions is, however, not exhaustive.

The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures/combinations.

The term “plurality” means “more than one” or “two or more.”

Some of the various component categories identified may overlap. In such cases where overlap may exist and the composition/product includes two overlapping components (or more than two overlapping components), an overlapping component does not represent more than one component. For example, a component such as a fatty ester may fall within the definition of a “fatty compound” and that of an “emulsifier”. If a particular composition/product requires both a fatty compound component and an emulsifier component, a single fatty ester can serve solely as a fatty compound or emulsifier (a single fatty ester cannot serve as both fatty compound and emulsifier).

All percentages, parts and ratios stated herein are based on the total weight of the compositions of the present invention unless otherwise noted.

An “alkyl radical” is a saturated, linear or branched hydrocarbon group, in particular in C ₁ -C ₈ , more particularly in C ₁ -C ₆ , more preferably in C ₁ -C ₄ , such as methyl, ethyl, isopropyl and tert-butyl;

An "alkoxy radical" is an alkyl-oxy in which the alkyl is as described above;

An “alkenyl radical” is an unsaturated hydrocarbon group, linear or branched, in particular C ₂ -C ₈ , more particularly C ₂ -C ₆ , preferably C ₂ -C ₄ , such as ethylenyl, propylenyl;

An “alkylene radical” is a divalent saturated hydrocarbon group, linear or branched, in C ₁ -C ₈ , in particular in C ₁ -C ₆ , preferably in C ₁ -C ₄ , such as methylene, ethylene or propylene.

All ranges and values described as used herein are inclusive and combinable. For example, any value or point described here that falls within a range described here may serve as a minimum or maximum value to derive a subrange, etc. Additionally, all ranges provided are intended to include each specific range within the given ranges, as well as any combination of subranges in between. So, a range of 1 to 5 specifically includes points 1, 2, 3, 4 and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc. ; and points 1, 2, 3, 4 and 5 include ranges and subranges of 1-5, 2-5, 3-5, 2-3, 2-4, 1-4, etc.

Apart from the working examples, or unless otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are understood to be modified by "approximately", whether or not expressly stated. Additionally, all numbers are intended to represent exact digits as additional embodiments, whether or not modified by "approximately." For example, “an amount of approximately 1%” includes an amount of exactly 1%. In another example, "an amount of 1%" includes an amount of approximately 1%. The term "approximately" is generally understood to encompass a range to within +/- 10% of the number stated, and is intended to cover quantities of +/- 1%, 2%, 3%, 4%, 5%, 6% , 7%, 8%, 9% and 10%.

The term "surfactants" includes salts of surfactants, even if they are not explicitly mentioned. In other words, whenever the disclosure refers to a surfactant, it is understood that salts of the surfactant are also included to the extent such salts exist, even though the specification may not specifically refer to a salt ( or may not refer to a salt in each case throughout the disclosure), for example, by using a language element such as "a salt thereof" or "salts thereof". Sodium and potassium are common cations that form salts with surfactants. However, other cations, such as ammonium ions or alkanolammonium ions, such as monoethanolammonium or triethanolammonium ions, can also form surfactant salts.

The term "substantially free" or "substantially free" as used herein means that the specific material may be present in small quantities which do not materially affect the fundamental and novel features of the claimed invention. For example, there may be less than 2% by weight of a specific material added to a composition, based on the total weight of the compositions (provided that less than 2% by weight does not materially affect the characteristics fundamental and new of the claimed invention). Likewise, the compositions may include less than 2% by weight, less than 1.5% by weight, less than 1% by weight, less than 0.5% by weight, less than 0.1% by weight, less than 0.05% by weight, or less than 0.01% by weight, or none of the specified material. The term "substantially free" or "substantially free" as used herein may also mean that the specific material is not added to the composition but may still be present in a raw material that is included in the composition.

Furthermore, any components that are positively set forth in the present disclosure may be negatively excluded from the claims, e.g., a claimed composition may be "free", "essentially free" (or "substantially free") of one or more components that are positively presented in the present disclosure.

All publications and patent applications cited herein are hereby incorporated by reference, and for all purposes, as if each individual publication or patent application were specifically and individually stated to be incorporated by reference. In the event of any inconsistency between this disclosure and any publication or patent application incorporated herein by reference, this disclosure shall control.
