Description

HAIR CARE COMPOSITIONS

Domain of disclosure

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

Context of the disclosure

Many individuals suffer from dry and damaged hair. Dryness and damage can occur due to several factors including exposure to weather, mechanical treatments (e.g. hair brushing), excessive treatments using chemicals, hair coloring, heat styling, etc In combination, using cleansers that can strip away natural oils from hair can also lead to split ends, dullness, and exacerbate dryness. To lessen the damage, oil treatments, conditioner, hair masks, and chemical treatments are commonly used.

The popularity and use of oils for dry hair treatments has grown 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, a problem is that effects are usually not seen after several hours (e.g. 8 hours) of treatment and multiple treatments are usually required, making them time consuming and labor intensive.

Individuals want a treatment for damaged hair or hair that is not time-consuming and labor-intensive to use. A variety of approaches have been developed to condition hair. A common method for imparting a conditioning benefit is through the use of rinse-out and leave-in conditioners and masks containing conditioning agents such as cationic surfactants and polymers, high melting fatty compounds, oils low melting point, 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 downsides with conventional conditioner products such as being too heavy on the hair or weighing the hair down and/or being greasy. Additionally, some products may not sufficiently condition or improve the sensory feeling of the hair or reduce the damaged feeling of the hair. Thus, there continues to be a need to provide hair care or hair treatment products which provide improved hair manageability, for example, improved hair alignment and reduced unwanted volume (including reduced frizz), as well as hair repair benefits or a less damaged feeling towards the hair (especially for damaged hair), a lighter feeling towards the hair (hair that does not weigh down) and an overall improved appearance of the hair. There is also a need to develop hair care products that can simultaneously impart other benefits in addition to care and conditioning benefits, such as shine, detangling, combability, smoothness, improved shape, discipline, and capped ends of desirable hair volume, curl definition (for curly or wavy hair), and restyleability (restyling) or reshaping (without the need for to reapply the product).

Disclosure Summary

The present disclosure relates to hair care and treatment compositions; and methods of conditioning and caring for hair using the compositions. The compositions are transparent and are anhydrous or substantially anhydrous (i.e., the amount of water may be about 10% by weight or less). When applied to wet or damp hair, or when the composition is brought into contact with external water, the composition forms an emulsion in a lamellar phase structure, which surprisingly accentuates the supply of active agents of conditioning such as cationic surfactants, emollients, and fatty compounds on a surface such as the hair. The deposition of these conditioning actives imparts a smoothing and lubricating effect to the hair, resulting in a shiny, healthy look and tactile repair feel to the hair. Hair is easily detangled and dryness and frizziness are reduced or minimized. Compositions typically include:

(a) about 20% by weight or more of one or more polyols;

(b) about 5 to about 70% by weight of one or more monoalcohols having 2 to 6 carbon atoms;

(c) about 2% by weight or less of one or more fatty alcohols selected from cetyl alcohol and myristyl alcohol;

(d) about 0.1 to about 5% by weight of one or more cationic surfactants;

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

(f) about 1% by weight or less of one or more dialkyl ethers; And

(g) 0% by weight to about 10% by weight water;

all weight percentages are based on the total weight of the composition.

The composition of the present disclosure is transparent and is solubilised, unemulsified until applied to wet or damp hair or brought into contact with external water, whereupon the composition forms an opaque emulsion. In one 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 to the hair immediately after shampooing and conditioning the hair, for example, as a rinse-out 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 the hair by themselves, without the need to use any other hair product. Additionally, the compositions are applied directly to wet or damp hair and then massaged into the hair to provide even coverage. The compositions can also first be combined with a small amount of external water, the mixture being applied immediately to the hair and the hair being massaged in to ensure even coverage. After application to hair, hair may be rinsed with water, dried, and styled as desired. Another unique aspect of the compositions is that they can be used as a leave-in product. The compositions can be applied to wet or damp hair or first with a small amount of external water, and left on the hair indefinitely, i.e., the hair composition is not removed or rinsed from the hair before drying and/or shaping or styling the hair.

The present disclosure relates to a hair care composition comprising:

(c) about 2% by weight or less of one or more fatty alcohols selected from cetyl alcohol and myristyl alcohol;

(d) about 0.1 to about 5% by weight of one or more cationic surfactants;

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

Hair treatment methods

The compositions of the present disclosure are useful for conditioning and/or managing hair. When the compositions are applied to wet or damp hair, they form a lamellar phase in situ . A "lamellar phase" generally refers to the packing of polar-headed, long-chain, non-polar tailed molecules in an environment of crude polar liquid (i.e., water from hair), as of sheets of bilayers separated by raw liquid. The compositions can be applied to wet or damp hair and the hair can be massaged, for example, with the hands, and/or spread all over the hair with a comb or brush. This results in smoothing and softening the hair, which reduces frizz, dryness, and unwanted volume, and increases shine. The compositions can remain in the hair or can optionally be rinsed out of the hair before drying and/or styling the hair.

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

The hair treatment methods according to the disclosure also include methods according to various routines. For example, the compositions can be mixed with a shampoo (or conditioner) before application to the hair. Alternatively, the composition can be coated on top of (or lathered into) the hair to which the shampoo (or conditioner) is already applied. In addition, the composition can be applied separately from the shampoo (or conditioner), i.e. applied to hair after shampoo (or conditioner) has been rinsed from hair.

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

The compositions can 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, single-dose packages, and bottles, including squeeze tubes and bottles. The package can be configured so that it can be attached to a wall, such as a wall in a bathroom, including the walls of a shower or bathtub. For example, the package may be a container that is configured to attach to a wall, such that when pressure is applied to the container, the composition 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 double 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 present disclosure, and the other tube may include a composition for use with the composition, for example, shampoo, conditioner, 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 present disclosure to the hair, leaving the composition on the hair for a sufficient amount of time, and rinsing the compositions from the hair. hair. The composition can be applied to the hair in sequence with other compositions. For example, the compositions can be applied to the hair before shampooing the hair, after shampooing the hair, before conditioning the hair, and/or after conditioning the hair. However, the compositions do not have to be used in sequence.

In some instances, the hair treatment compositions are used in conjunction with additional hair treatment compositions on a routine basis, for example, during an individual's normal shower/bath routine. The hair treatment composition can be applied to the hair individually or can be combined with one or more additional compositions. Combining compositions with one or more additional compositions (e.g., shampoo, conditioner, rinse aid, etc.) can be helpful in eliminating multiple steps from a routine. For example, the hair treatment composition can be mixed with a shampoo (or conditioner) before application to the hair. In this case, the mixture of shampoo (or conditioner) and hair treatment composition is simultaneously applied to the hair during the cleansing or conditioning process and simultaneously rinsed from the hair. Alternatively, the hair treatment composition can be layered onto (or lathered into) hair to which shampoo (or conditioner) has already been applied or vice versa. In this case, the hair treatment composition can 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 applied to the hair first 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 conditioner, the hair treatment composition can be mixed or used with the shampoo and/or conditioner in a ratio of from 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 this disclosure: shampoo/conditioner, etc.).

The hair treatment compositions of the present disclosure can remain on the hair for a minimum period of time before being rinsed out of the hair, but the hair treatment composition need not be left on the hair for an extended period of time. Conveniently, the hair treatment compositions can be applied and left on the hair for a period of time that is typical of normal shampooing and/or conditioning. For example, the hair treatment composition (whether or not combined with another hair treatment composition such as a shampoo or conditioner) can be applied to the hair and left on the hair for a few seconds (1, 2 , 3, or 5 seconds) up to about 1 minute, about 2 minutes, about 5 minutes, about 10 minutes, about 15 minutes, about 20 minutes, about 25 minutes, or about 30 minutes.

When the hair treatment composition is not mixed with another composition before application to the hair, the hair treatment composition can be applied to the hair immediately after or before the hair is (is) treated with another composition (for example, shampoo and/or conditioner). For example, the hair treatment compositions can be applied to the hair within about a few seconds or 1 minute, 2 minutes, 5 minutes, 10 minutes, or 20 minutes before or after shampooing and/or conditioner is (either) applied to the hair.

In various embodiments, the compositions of the present disclosure can be

- mixed with a shampoo before application to the hair; Or

- deposited in layer on the hair with a shampoo; Or

- applied to the hair after a shampoo has been rinsed from the hair; Or

Evaluation on hair

Example 7A Sensory Effect on Strands of Hair

The sensory effect of formulas A and B of the invention was evaluated on locks of hair and it was compared to the sensory effect of the comparative formula P.

First, two grams of platinum-lightened hair strands were washed with a standard sulfate-based shampoo and rinsed with water. The locks were then treated with formulas of the invention by massaging each lock of hair for 30 seconds with 0.8 grams of product. The locks were then rinsed with water for 30 seconds and allowed to air dry.

The dry treated locks were rated by five experts for sensory feeling. Four of the five experts selected inventive formulas A and B as conferring a better sensory effect of soft feeling on the treated hair compared to comparative formula P.

Example 7B Hair Salon Screening

A formula of the invention of Example 1 and a comparative formula X based on the formula of the invention but not containing dicaprylyl ether and consisting of 100% by weight of propylene glycol were used to treat the hair of human volunteers (N = 3) in a salon, of medium to long hair length, with loose curls, fine to medium diameter, and chemically damaged. Professional salon hairdressers evaluated the treated hair and found that overall cosmetic, care, and manageability attributes such as, – detangling, combing, smoothness, feeling of conditioning, shape, discipline, and sealed ends were significantly better on the hair treated with the formula of the invention than on the hair treated with the comparative formula X.

Example 7C Salon Screening of Hair

In a salon trial, human volunteers (N = 2) hair of medium to long length, with loose curls, fine to coarse diameter, and chemically damaged hair were first shampooed and rinsed. A formula of the invention of example 1 and a comparative formula R were then used to treat the hair. The professional salon hairdressers evaluated the treated hair and found that the attributes of detangling, combing, smoothness, feeling of conditioning were better on hair treated with the formula of the invention than on hair treated with the comparative formula R during rinsing, while the hair was still wet and when the hair was dry.

Example 7D Hair Salon Screening

In a salon trial, the hair of human volunteers (N=6) (chemically damaged) was first shampooed and rinsed. A formula of the invention from Example 1 and a comparative formula X were used to treat the hair of human volunteers (N=6) with chemically damaged hair in a salon. Professional salon hairstylists have evaluated treated hair and found care performance attributes during application, rinsing, and on wet and damp hair, visual smoothness and shine are best on hair treated with the formula of the invention only on the hair treated with the comparative formula X.

Example 7E Hair Salon Screening

In a salon trial, human volunteers (N = 2) of medium to long length, loose curls, fine to coarse diameter, and chemically damaged hair were first shampooed and rinsed. A formula of the invention of example 1 and a comparative formula S were then used to treat the hair. Professional salon hairstylists evaluated the treated hair and found that the attributes of smoothness, and feeling of conditioning were significantly better on hair treated with the inventive formula than on hair treated with Comparative Formula S.

The terms "comprising", "having", and "including" are used in their broad, non-limiting sense.

The terms "a", "an", "the" and "the" are understood to include the plural as well as the singular.

The compositions and methods of this disclosure may include, 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-in" product. A "leave-in" product refers to a hair treatment composition which is applied to the hair and is not subjected to immediate rinsing and/or washing for at least 4 hours or for a period of 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 before styling the hair.

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

All ranges and values disclosed herein are inclusive and combinable. For example, any value or point described here that falls within a range described here can be used as a minimum or maximum value to derive a sub-range, etc. Further, all ranges provided here are intended to include each specific range within the given ranges, and any combination of subranges therebetween. Thus, a range of 1 to 5, specifically includes 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 working examples, or unless otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all cases by the term "approximately", meaning within +/- 5 % near the indicated number.

As used herein, the term "at least one" is interchangeable with the term "one or more" and thus includes individual components as well as mixtures/combinations.

The term "active ingredient" as used herein in relation to the percentage amount of an ingredient or raw material, refers to 100% activity of the ingredient or raw material.

"Cosmetically acceptable" means that the article 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" as used in this disclosure.

The terms "a", "an", "the" and "the" are understood to include the plural as well as the singular. Thus, the expression “a mixture thereof” also relates to “mixtures thereof”. Throughout the disclosure, the phrase "a mixture thereof" is used, following a list of items as shown in the following example where the letters A through F represent the items: "one or a plurality of elements selected from the group consisting of A, B, C, D, E, F, and a mixture thereof. The phrase "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 can be included). Rather, it indicates that a mixture of two or more of any two of A, B, C, D, E, and F may be included. In other words, it is equivalent to the phrase "one or more items selected from the group consisting of A, B, C, D, E, F, and a mixture of two or more of any two of A, B, C, D, E, and F”.

Similarly, the phrase "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, and a mixture thereof", it is indicating 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 referred to throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. However, the list of counterions is not limiting.

The term "included" for a concentration range means that the limits of the range are included in the defined interval.

"Volatile", as used herein, means having a flash point of at least about 100°C.

"Non-volatile", as used herein, means having a flash point of greater than about 100°C.

The term "polymers", as used herein, includes homopolymers and copolymers formed from two or more different types of monomers.

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

As used herein, all ranges provided are intended to include each specific range within the given ranges, and a combination of the subranges therebetween. Thus, a range of 1-5, specifically includes 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 presented in the present disclosure can be negatively excluded from the claims. In other words, the compositions (nanoemulsions) of this disclosure may be free or substantially free of all components and elements positively cited throughout this disclosure.

Some of the various component categories identified may overlap. In such cases where an overlap may exist and the composition includes both components (or the composition includes more than two overlapping components), an overlapping compound does not represent more than one component. For example, a fatty acid can 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 only as a nonionic surfactant or only as a fatty compound (the single fatty acid does not serve as both a nonionic surfactant and a fatty compound).

All publications and patent applications cited in this specification are hereby incorporated by reference, and for all intents and purposes, as if each individual publication or patent application were specifically and individually indicated as incorporated by reference. In the event of any inconsistency between this disclosure and any publication or patent application incorporated herein by reference, this disclosure prevails.
