TITLE

HAIR CARE COMPOSITIONS COMPRISING POLYOL, C2-6 MONOALCOHOL AND CATIONIC SURFACTANT

CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims benefit of priority to French Application Serial No. 2006214, filed on June 15, 2020, and to United States Patent Application Serial No. 63/002,820, filed on March 31 , 2020, the disclosure of which is incorporated by reference as if fully rewritten herein.

FIELD OF THE DISCLOSURE

The present disclosure relates to hair care and treatment compositions and to methods for caring for and providing cosmetic benefits to the hair using the compositions.

BACKGROUND

Many individuals suffer from dry and damaged hair. Dryness and damage can occur due to several factors including weather exposure, mechanical treatments (e.g. brushing hair), excessive treatments using chemicals, dying hair, heat styling, etc. In combination, using cleansing products that can be excessively stripping of hair's natural oils, can also lead to split ends, dull hair, and exacerbate dry hair. To mitigate the damage, oil treatments, conditioner, hair masks, and chemical treatments are commonly used.

The popularity and usage of oils for dry hair treatments 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, one problem is that effects are not usually seen after more than several hours (e.g. 8 hours) of treatment and several treatments are usually required, making it time consuming and labor intensive.

Individuals desire a treatment for hair or damaged hair that is not time consuming and labor intensive to use. A variety of approaches have been developed to condition the hair. A common method of providing conditioning benefit is through the use of rinse- off and leave-on hair conditioners and masks containing conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point oils, silicone compounds, and mixtures thereof. Such products typically contain a substantial amount of water or are in the form of emulsions.

However, there could still be some drawbacks to conventional conditioner products such as being too heavy on the hair or weighing down the hair and/or being greasy. In addition, some products may not sufficiently condition or improve the sensorial feel of the hair or reduce the damaged feel of hair. Thus, there is still a need for providing hair care or hair treatment products which provide improved hair manageability, for example, improved hair alignment and reduced unwanted volume (especially reduced frizz), as well as hair repair benefits or less damaged feel to hair (especially for damaged hair), a weightless feel on hair (hair is not weighed down) and improved overall appearance of the hair. There is also a need to develop hair care products that can impart other benefits at the same time in addition to caring and conditioning benefits, such as improved shine, detangling, ease of combing, smoothness, shape, discipline, and sealed ends of the hair desirable volume, curl definition (for curly or wavy hair), and restylability or reshaping (without the need to reapply the product).

SUMMARY OF THE DISCLOSURE

The instant disclosure relates to hair care and treatment compositions; and to methods for conditioning and caring for the hair using the compositions. The compositions are transparent and are anhydrous or substantially anhydrous (i.e., the amount of water can be about 10 wt.% or less). Upon application to wet or damp hair, or when the composition is contacted with extraneous water, the composition forms an emulsion in a lamellar phase stucture, which surprisingly enhances the delivery of conditioning active agents such as cationic surfactants, emollients, and fatty compounds onto a surface such as hair. The deposition of these conditioning active agents impart a smoothing and lubricating effect to the hair, resulting in the hair having a shiny and healthy appearance and tactile repairing sensation. The hair is easily detangled and dryness and frizziness are reduced or minimized. The compositions typically include:

(a) about 20 wt.% or higher of one or more polyols;

(b) about 5 to about 70 wt.% of one or more monoalcohols having from 2 to 6 carbon atoms; (c) about 2 wt.% or less of one or more fatty alcohols selected from cetyl alcohol and myristyl alcohol;

(d) about 0.1 to about 5 wt.% of one or more cationic surfactants;

(e) about 1 wt% or less of one or more fatty carbonate esters;

(f) about 1 wt% or less of one or more dialkyl ethers; and

(g) 0 wt.% to about 10 wt.% of water; all percentages by weight are based on the total weight of the composition.

The composition of the present disclosure is transparent and is solubilized, non- emulsified until applied to wet or damp hair or put in contact with extraneous water, whereupon the composition forms an opaque emulsion. In an embodiment, the resulting opaque emulsion has a lamellar phase structure.

The compositions of the present disclosure can be applied immediately after shampooing the hair, for example, in place of a conditioner. The compositions can also be applied on hair immediately after shampooing and conditioning the hair, for example, as a rinse-off or leave-in treatment. The compositions can also be applied before shampooing the hair as pre-shampoo treatment compositions. The compositions can also be used on hair by themselves, without requiring the use of any other hair product. Moreover, the compositions are applied directly to wet or damp hair and massaged into the hair to ensure uniform coverage. The compositions can also first be combined with a small amount of extraneous water, with the resulting mixture being applied immediately onto hair and massaged into the hair to ensure uniform coverage. After application to the hair, the hair may be rinsed with water, dried, and styled as desired. Another unique aspect of the compositions is that they may be used as a leave-on product. The compositions can be applied to wet or damp hair or first mixed with a small amount of extraneous water, and allowed to remain on the hair indefinitely, i.e., the hair composition is not removed or rinsed from the hair prior to drying and/or shaping or styling the hair.

The term "transparent” with respect to a transparent composition indicates that the composition has transmittance of at least 80% at a wavelength of 600 nm, for example measured using a Lambda 40 UV-visible spectrometer. The compositions may have, for example, a transmittance of at least 80%, at least 90%, or at least 95% at a wavelength of 600 nm, measured, for example, using a Lambda 40 UV-visible spectrometer. The term “transparent” is interchangeable with the term “clear” for purposes of the instant disclosure. The term "transparent” can also mean that an article is visible to the human eye when looking through the composition contained in a clear glass bottle.

The compositions can be substantially anhydrous. The phrase “substantially anhydrous” is interchangeable with the phrase “essentially free of water” or “substantially free of water.” A substantially anhydrous composition may include up to 10 wt.% of water regardless of whether the water is added to the composition or part of a raw material. Nonetheless, the substantially anhydrous composition may include less than 9 wt.%, less than 8 wt.%, less than 7 wt.%, less than 6 wt.%, less than 5 wt.%, less than 4 wt.%, less than 3 wt.%, less than 2 wt.%, less than 1 wt.%, or less than 0.5 wt.% of water.

The compositions can be anhydrous, that is, they do not contain water or are free of water (added water or part of a raw material).

The compositions of the instant disclosure typically have a viscosity at 25°C of about 10 mPa.s to about 10,000 mPa.s or about 10 mPa.s to about 8,000 mPa.s, or about 10 mPa.s to about 6,000 mPa.s, or about 10 mPa.s to about 4,000 mPa.s, or about 10 mPa.s to about 2,000 mPa.s, or about 10 mPa.s to about 1 ,000 mPa.s, or about 10 mPa.s to about 800mPa.s, or about 10 mPa.s to about 600 mPa.s, or about 10 mPa.s to about 500 mPa.s, or about 10 mPa.s to < 500 mPa.s, including ranges and sub-ranges there between. The viscosity measurements can be carried out, for example, using a Broooksfield viscometer, Model RVT (Brookfield Engineering Laboratories, Inc.) at about 20 revolutions per minute (RPM), at ambient room temperature of about 20 to 25°C; spindle sizes may be selected in accordance with the standard operating recommendations form the manufacturer, ranging from disk spindle No. 1 to No. 4.

In an embodiment, when combined with the extraneous water, the cosmetic composition forms an emulsion, which typically is opaque and has a viscosity that is greater than that of the solubilized, non-emulsified, transparent composition prior to combination with the extraneous water.

In an embodiment, when combined with the extraneous water, the cosmetic composition forms an emulsion, in situ (either on the hair or on skin or other parts of the body), which typically is opaque and has a viscosity that is greater than that of the solubilized, transparent composition prior to combination with the extraneous water.

In some cases, the total amount of dialkyl ether(s)is from about 0.05 to about 1 wt.%, about 0.07 to about 1 wt.%, about 0.08 to about 1 wt.%, about 0.1 to about 0.9 wt.%, about 0.2 to about 0.7 wt.%, about 0.3 to about 0.6 wt.%, or about 0.3 to about 0.5 wt.%, including ranges and sub-ranges there between, based on the total weight of the composition.

In certain embodiments, the total amount of the one or dialkyl ether(s)) in the composition is about 1 wt,%, 0.9 wt,%, 0.8 wt,%. 0.7 wt,%, 0.6 wt,%, 0.5 wt,%, 0.4 wt,%, 0.3 wt,%, 0.2 wt,%, 0.1 wt,%, 0.08 wt,%, 0.07 wt,%, 0.06 wt,%, 0.05 wt,%, 0.04 wt,%, 0.03 wt,%, 0.02 wt,%, or 0.01 wt,%, based on the total weight of the composition. The total amount of fatty carbonate ester(s) is typically at least the same or higher than the total amount of the dialkyl ether(s) in the compositions. The compositions may include more fatty carbonate ester(s) than dialkyl ether(s), i.e., a higher weight percent of the composition is a fatty carbonate ester(s) than dialkyl ether(s). The ratio of fatty carbonate ester(s) to the total amount of dialkyl ether(s) (fatty carbonate ester(s): dialkyl ether(s)) may be from about 2:1 to 1 :1 , about 2:1 to 1.1 :1 , about 2:1 to 1 .2:1 , about 2;1 to 1 .3:1 , about 2:1 to 1 .4:1 , about 2:1 to 1 .5:1 , about 2:1 to 1 .6:1 , about 2:1 to 1 :7:1 , or about 2:1 to 1 .8:1 , including ranges and sub-ranges there between.

Water

The hair care compositions may be devoid of added water, i.e., the compositions do not contain water that is added to the composition or present in a raw material.

The hair care composition can comprise from 0 up to about 10 wt.% of water.

In some instances, the water present in the hair care composition prior to combination with extraneous water is added to the composition (“added water”). In some instances, the water present in the cosmetic composition prior to combination with extraneous water is not “added water,” i.e., it is present in the hair care composition as part of a raw material that is included in the composition. Although the hair care composition may include water prior to the combination of extraneous water, in some embodiments the hair care composition is anhydrous or devoid of water.

Methods of Treating Hair

The compositions of the instant disclosure are useful for conditioning and/or managing the hair. When the compositions are applied to wet or damp hair they form a lamellar phase in situ. A “lamellar phase” refers generally to packing of polar-headed long chain nonpolar-tail molecules in an environment of bulk polar liquid (i.e., water from the hair), as sheets of bilayers separated by bulk liquid. The compositions can be applied to the wet or damp hair and may be massaged into the hair, for example, with the hands, and/or spread throughout the hair with a comb or brush. This results in a smoothing and softening of the hair, which reduces frizz, dryness, and unwanted volume, and increases shine. The compositions can remain in the hair or can optionally be rinsed from the hair prior to drying and/or styling of the hair.

Another unique aspect of the compositions is that they may be used as a leave-on product. The compositions can be applied to wet or damp hair and allowed to remain on the hair indefinitely, i.e., the hair composition is not removed or rinsed from the hair prior to styling the hair.

The methods of treating hair according to the disclosure also include methods according to various routines. For instance, the compositions may be mixed with a shampoo (or conditioner) prior to application to the hair. Alternatively, the composition may be layered on top of (or lathered into) hair to which the shampoo (or conditioner) is already applied. Furthermore, the composition may be applied separate from the shampoo (or conditioner), i.e., applied to the hair after the shampoo (or conditioner) has been rinsed from the hair.

The compositions of the instant disclosure may be incorporated into a kit. For example, the kits may include at least one composition according to the instant disclosure and one or more additional compositions, for example, a shampoo, a conditioner, etc. The various compositions are separately contained in the kits. In some instances, the kits include one or more compositions according the instant disclosure, a shampoo, and/or a conditioner, all of which are separately contained. The kits may also include one or more compositions according the instant disclosure, a shampoo, and a conditioner. Instructions, mixing components, brushes, gloves, measuring tools, etc., may also optionally be included in the kits.

The compositions may be packaged in a variety of different containers, such as, for example, a ready-to-use container. Non-limiting examples of useful packaging include tubes, jars, caps, unit dose packages, and bottles, including squeezable tubes and bottles. The packaging may be configured so that it can be attached to a wall, such as a wall in a bathroom, including walls of a shower or tub. For example, the packaging can be a container that is configured to attach to a wall, such that when pressure is applied to the container, the composition contained therein is expelled from one or more openings in the container. In some cases, the packaging is a tube, such as a tube with two compartments, or dual tubes, each forming a separate compartment. Each compartment may include a different composition. For example, one tube or compartment may include a composition according to the instant disclosure, and the other tube may include a composition to be used with the composition, for example, a shampoo, a conditioner, an all-in-one shampoo/conditioner (i.e., a conditioning shampoo; also referred to as a “co wash”).

Methods of treating hair according to the disclosure may vary but typically include applying a composition of the instant disclosure to the hair, allowing the composition to remain on the hair for a sufficient amount of time, and rinsing the compositions from the hair. The composition may be applied to the hair in a sequence with other compositions. For example, the compositions may be applied to the hair before shampooing the hair, after shampooing the hair, before conditioning the hair, and/or after conditioning the hair. The compositions, however, are not required to be used in a sequence.

In some cases, the compositions are used in conjunction with additional hair- treatment compositions in a routine, for example, during an individual’s normal showering/bathing routine. The composition may be applied to the hair individually or may be combined with one or more additional compositions. Combining the compositions with one or more additional compositions (e.g., a shampoo, a conditioner, a rinse, etc.) can be useful for eliminating multiple steps from a routine. For instance, the composition may be mixed with a shampoo (or conditioner) prior to application to the hair. In this case, the mixture of the shampoo (or conditioner) and the composition are simultaneously applied to the hair during the cleansing or conditioning process and simultaneously rinsed from the hair. Alternatively, the composition may be layered on top of (or lathered into) hair to which a shampoo (or conditioner) has already been applied or vice versa. In this case, the composition may be applied to the hair and without rinsing it from the hair, a shampoo (or conditioner) is then subsequently applied to the hair. Alternatively, the shampoo (or conditioner) may be first applied to the hair and without rinsing the shampoo (or conditioner) from the hair, the hair-treatment composition is also applied to the hair.

When used in conjunction with a shampoo and/or a conditioner, the composition may be mixed or used with the shampoo and/or conditioner in a ratio of about 1 :10 to about 10:1 , about 1 :5 to about 5:1 , about 1 :3 to about 3:1 , about 1 :2 to about 2:1 , about 1 :1 to about 4:1 , about 1 :1 to about 3:1 , or about 1 :1 to about 2:1 (hair-treatment composition of the instant disclosure: shampoo/conditioner, etc.).

The compositions of the instant disclosure may be allowed to remain on the hair for a minimum amount of time before being rinsed from the hair, but it is not necessary to allow the composition to remain on the hair for an extended period of time. Conveniently, the compositions can be applied and allowed to remain on the hair for a period of time that is typical for regular shampooing and/or conditioning. For example, the composition (whether combined with another hair-treatment composition such as a shampoo or conditioner) may be applied to the hair and allowed to remain on the hair for a few seconds (1 , 2, 3, or 5 seconds) up to about 1 , about 2, about 5, about 10, about 15, about 20, about 25, or about 30 minutes.

When the composition is not being mixed with another composition prior to application to the hair, the composition may be applied to the hair immediately after or before the hair it treated with another composition (e.g., a shampoo and/or a conditioner). For example, the hair-treatment compositions may be applied to the hair within about 1 , 2, 5, 10, or 20 minutes before or after a shampoo and/or a conditioner is applied to the hair.

Example 7A Sensorial Effect on hair swatches

The sensorial effect of invention formulas A and B on hair swatches was evaluated and compared to the sensorial effect of comparative formula P.

Two-grams of platinum bleached hair swatches were first washed with a conventional sulfate-based shampoo and rinsed off with water. The swatches were then treated with invention formulas by massaging 0.8 grams of product onto each hair swatch for 30 seconds. The swatches were then rinsed with water for 30 seconds and then allowed to air dry.

The dry treated swatches were evaluated by five experts for sensory feel. Four out of the five experts selected invention formulas A and B as providing a better sensorial effect of smooth feel on the treated hair as compared to comparative formula P.

Example 7B Salon Screening in Hair

An invention formula from Example 1 and a comparative formula X based on the invention formula but not containing dicaprylyl ether and made up to 100 wt.% with propylene glycol were used to treat the hair of human volunteers (N=3) in a salon, the hair of a length from medium to long, with loose curls, fine to medium diameter, and chemically damaged. The professional salon hair dressers evaluated the treated hair and found that the attributes of overall cosmeticity, care, and manageability such as, - detangling, combing, smoothness, conditioning feel, shape, discipline, and sealed ends were found to be noticeably better on the hair treated with the invention formula than on the hair treated with comparative formula X.

Example 7C Salon Screening in Hair

In a salon test, the hair of human volunteers (N=2) of a length from medium to long, with loose curls, fine to coarse diameter, and chemically damaged were first shampooed and rinsed.

The professional salon hair dressers evaluated the treated hair and found that the attributes of detangling, combing, smoothness, conditioning feel were found to be better on the hair treated with the invention formula than on the hair treated with comparative formula R during rinsing, while the hair was still wet and when the hair was dry.

Example 7D Salon Screening in Hair

In a salon test, the hair of human volunteers (N=6) (chemically damaged) were first shampooed and rinsed. An invention formula from Example 1 and comparative formula X were used to treat the hair of human volunteers (N=6) with chemically damaged hair in a salon. The professional salon hair dressers evaluated the treated hair and found that the attributes of care performances during application, rinse, and on wet and dry hair, visual smoothness and shine were found to be better on the hair treated with the invention formula than on the hair treated with comparative formula X.

Example 7E Salon Screening in Hair

In a salon test, the hair of human volunteers (N=2) of a length from medium to long, with loose curls, fine to coarse diameter, and chemically damaged were first shampooed and rinsed. An invention formula from Example 1 and a comparative formula S were then used to treat the hair. The professional salon hair dressers evaluated the treated hair and found that the attributes of smoothness, and conditioning feel were found to be noticeably better on the hair treated with the invention formula than on the hair treated with comparative formula S. The terms “comprising,” “having,” and “including” are used in their open, non limiting sense.

The terms “a” and “the” are understood to encompass the plural as well as the singular.

The compositions and methods of the present disclosure can comprise, consist of, or consist essentially of the essential elements and limitations of the disclosure described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful.

The compositions described throughout this disclosure may be a “leave-on” product. A "leave-on" (also called leave-in) product refers to a hair treatment composition that is applied to hair and is not subjected to immediate rinsing and/or washing for at least 4 hours or for a period of time ranging from 4 hours up to 72 hours, from 4 hours up to 48 hours, or from 8 hours up to 36 hours, or from 8 hours up to 24 hours. In other words, the product is applied to the hair and remains on the hair, as styled, i.e., it is not removed from the hair prior to styling the hair.

All percentages, parts and ratios herein are based upon the total weight of the compositions of the present disclosure, unless otherwise indicated.

All ranges and values disclosed herein are inclusive and combinable. For examples, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value to derive a sub-range, etc. Furthermore, all ranges provided are meant to include every specific range within, and combination of sub ranges between, the given ranges. Thus, a range from 1 -5, includes specifically 1 , 2, 3, 4 and 5, as well as sub ranges such as 2-5, 3-5, 2-3, 2-4, 1 -4, etc.

Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term “about,” meaning within +/- 5% of the indicated number. As used herein, the expression “at least one” is interchangeable with the expression “one or more” and thus includes individual components as well as mixtures/combinations.

The term “active material” as used herein with respect to the percent amount of an ingredient or raw material, refers to 100% activity of the ingredient or raw material.

“Cosmetically acceptable” means that the item in question is compatible with a keratinous substrate such as skin and hair. For example, a “cosmetically acceptable carrier” means a carrier that is compatible with a keratinous substrate such as skin and hair.

The term “hair care” is interchangeable with the term “hair treatment” for purposes of the instant disclosure.

The terms “a,” “an,” and “the” are understood to encompass the plural as well as the singular. Thus, the term “a mixture thereof” also relates to “mixtures thereof.” Throughout the disclosure, the term “a mixture thereof” is used, following a list of elements as shown in the following example where letters A-F represent the elements: “one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture thereof.” The term, “a mixture thereof” does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of any two or more of A, B, C, D, E, and F can be included. In other words, it is equivalent to the phrase “one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F.”

Likewise, the term “a salt thereof” also relates to “salts thereof.” Thus, where the disclosure refers to “an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, and a mixture thereof,” it indicates that that one 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. The salts referred to throughout the disclosure may include salts having a counter ion such as an alkali metal, alkaline earth metal, or ammonium counter-ion. This list of counter-ions, however, is non-limiting.

The expression "inclusive" for a range of concentrations means that the limits of the range are included in the defined interval.

"Volatile", as used herein, means having a flash point of less than about 100^QC.

"Non-volatile", as used herein, means having a flash point of greater than about

100^QC.

The term "polymers," as defined herein, include homopolymers and copolymers formed from at least two different types of monomers.

The term “INCI” is an abbreviation of International Nomenclature of Cosmetic Ingredients, which is a system of names provided by the International Nomenclature Committee of the Personal Care Products Council to describe personal care ingredients.

As used herein, all ranges provided are meant to include every specific range within, and combination of sub ranges between, the given ranges. Thus, a range from 1 - 5, includes specifically 1 , 2, 3, 4 and 5, as well as sub ranges such as 2-5, 3-5, 2-3, 2-4,

1 -4, etc.

All components and elements positively set forth in this disclosure can be negatively excluded from the claims. In other words, the compositions (nanoemulsions) of the instant disclosure can be free or essentially free of all components and elements positively recited throughout the instant disclosure.

Some of the various categories of components identified may overlap. In such cases where overlap may exist and the composition includes both components (or the composition includes more than two components that overlap), an overlapping compound does not represent more than one component. For example, a fatty acid may be characterized as both a nonionic surfactant and a fatty compound. If a particular composition includes both a nonionic surfactant and a fatty compound, a single fatty acid will serve as only the nonionic surfactant or as only the fatty compound (the single fatty acid does not serve as both the nonionic surfactant and the fatty compound). All publications and patent applications cited in this specification are herein incorporated by reference, and for any and all purposes, as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. In the event of an inconsistency between the present disclosure and any publications or patent application incorporated herein by reference, the present disclosure controls.
