Description

HAIR TREATMENT COMPOSITIONS

Domain of disclosure

The present disclosure relates to hair treatment compositions, and methods of applying and conditioning hair with such hair treatment 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 the weather, mechanical treatments (e.g. hair brushing), excessive treatment using chemicals, hair dyeing, styling, etc. In combination, the use of cleansing products that can strip natural oils from hair in excess can lead to split ends, dull hair, and exacerbate dry hair. 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 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, 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 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 hair. A common method of imparting a conditioning benefit is the use of conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point oils, silicone compounds, and their mixtures. Most of these conditioning agents are known to provide various conditioning benefits.

However, there is still a need to provide improved hair manageability and conditioning.

Disclosure Summary

Aspects of the present disclosure relate to hair treatment compositions for conditioning hair. The inventors have discovered that hair treatment compositions can be formulated to have lamellar gel networks that are responsive to pH changes in the hair treatment compositions. For example, changes in pH of the hair treatment composition can lead to precipitation of certain ingredients of the lamellar gel network. Without being limited to any specific theory, it is believed that raising the pH of the hair treatment composition of the present disclosure above the pKa of the fatty acids, for example, by the addition of external water to dilute the composition, may destabilize the lamellar gel network, which promotes the deposition of certain ingredients (eg, hair conditioning ingredients) on a user's hair.

It should be understood that the various aspects are not limited to the arrangements and instrumentalities shown in the drawings.

Aspects of the present disclosure relate to hair treatment compositions. The hair treatment compositions can condition the hair, improve the visual appearance of the hair, and/or strengthen the hair. The hair treatment compositions disclosed herein can be formulated to have a lamellar gel network that changes under certain conditions. For example, hair treatment compositions can be formulated with specific ingredients in certain ratios so that the lamellar gel network is responsive to (eg, changes due to) an increase in pH, which promotes the precipitation of hair conditioning ingredients (eg, emollients, silicones, certain fatty compounds). In at least one embodiment, the hair treatment composition has a pH that is lower than the pKa of the fatty acids, such that an increase in the pH of the hair treatment composition (eg, by diluting the hair treatment composition with external water) above the pKa of the fatty acid changes the lamellar gel network (for example, by destabilizing the lamellar network) to promote the precipitation and deposition of certain ingredients on the user's hair. The inventor has discovered that the hair treatment compositions impart an improved disposition of certain desired ingredients to the hair and impart improved attributes to the hair.

The pH of the hair treatment composition is typically 2.5 to 5.5. For example, the pH of the hair treatment composition can be about 2.5 to about 5.25, 2.5 to about 5, 2.5 to about 4.75, 2.5 to about 4.5 , 2.5 to about 4.25, 2.5 to about 4, 2.5 to about 3.75, 2.5 to about 3.5, 2.5 to about 3.25, 2.5 to about 3 ; about 2.75 to about 5.5, about 2.75 to about 5.25, about 2.75 to about 5, about 2.75 to about 4.75, about 2.75 to about 4.5, about 2, 75 to about 4.25, about 2.75 to about 4, about 2.75 to about 3.75, about 2.75 to about 3.5; about 3 to about 5.5, about 3 to about 5.25, about 3 to about 5, about 3 to about 4.75, about 3 to about 4.5, about 3 to about 4.25, about 3 to about 4 , about 3 to about 3.75; about 3.25 to about 5.5, about 3.25 to about 5.25, about 3.25 to about 5, about 3.25 to about 4.75, about 3.25 to about 4.5, about 3, 25 to about 4.25, about 3.25 to about 4; about 3.5 to about 5.5, about 3.5 to about 5.25, about 3.5 to about 5, about 3.5 to about 4.75, about 3.5 to about 4.5, about 3, 5 to about 4.25; about 3.75 to about 5.5, about 3.75 to about 5.25, about 3.75 to about 5, about 3.75 to about 4.75, about 3.75 to about 4.5; about 4 to about 5.5, about 4 to about 5.25, about 4 to about 5, about 4 to about 4.75; about 4.25 to about 5.5, about 4.25 to about 5.25, about 4.25 to about 5; about 4.25 to about 5.25, about 4.25 to about 5, about 4 to about 4.75; about 4.25 to about 5.25, or about 4.25 to about 5, ranges and subranges included.

The hair treatment composition can be formulated so that the carbon chain of the cationic surfactant has a length which is within 10 carbon atoms of the carbon chain length of the fatty acid. In other words, the cationic surfactant and the fatty acid can be chosen so that the carbon chain length of the cationic surfactant is not greater than the carbon chain length of the fatty acid by 10 carbon atoms. and is also not less than the carbon chain length of the same fatty acid by 10 carbon atoms.

The hair treatment compositions of the present disclosure can be incorporated into a kit. For example, kits can include at least one hair treatment composition according to the present disclosure and one or more additional compositions, eg, shampoo, conditioner, etc. The various compositions are contained separately in the kits. In some instances, kits include one or more hair treatment compositions according to the present disclosure, a shampoo, conditioner, mask, and/or other hair treatment product, all of which are contained separately. Instructions, mixing components, measuring tools, etc. may also be optionally included in 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, bottles, and sprayable containers. The wrap can be configured to 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 that is contained 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 hair treatment composition according to the present disclosure, and the other tube may include a composition for use with the hair treatment composition, for example, shampoo, conditioner, shampoo all-in-one conditioner/conditioner (ie, a conditioning shampoo; also referred to as a “co-wash” mask) or other hair treatment products.

Hair treatment method

Aspects of the present disclosure also relate to methods of making and using such hair treatment compositions. A method of treating and conditioning hair according to aspects of the disclosure typically include:

(I) applying a hair treatment composition, the hair treatment composition comprising:

(a) about 0.1 to about 10% by weight of a cationic surfactant;

(b) about 0.1 to about 10% by weight of a fatty acid having a carbon chain of 12 or more carbons;

wherein a molar ratio of total amount of cationic surfactant to total amount of fatty acid is from about 1:1.05 to about 1:3,

(c) about 0.1 to about 20% by weight of a fatty alcohol; And

(d) about 50% by weight of water or more,

wherein the hair treatment composition has a pH of about 2.5 to about 5.5, and all weight percentages are based on the total weight of the hair treatment composition, and

(II) rinsing the hair treatment composition from the hair.

Methods of treating and/or conditioning hair according to the disclosure may vary, but typically include applying a hair treatment composition as disclosed herein, leaving the hair treatment composition on the hair for sufficient time, and rinsing the hair of the hair treatment composition. The hair treatment composition can be applied to hair in sequence with other compositions. For example, the hair treatment composition can be applied to hair (wet or dry) before shampooing the hair, after shampooing the hair, before applying a conditioner to the hair, and/or after applying a conditioner to the hair , etc. However, the hair treatment compositions are not required 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 common shower/bath routine. The hair treatment composition can be applied to the hair individually or can be combined with one or more additional compositions. 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 the shampoo (or conditioner) and the 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 on top of (or lathered into) hair to which shampoo (or conditioner) has already been applied or vice versa . In this case, the shampoo (or conditioner) can be applied first to the hair and without rinsing the shampoo (or conditioner) from the hair, the hair treatment composition is also applied to the hair. Alternatively, 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.

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 may be left on the hair for a minimum period of time before rinsing it from the hair, but it is not necessary to leave the hair treatment composition 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 which is typical for regular shampooing and/or conditioning. For example, the hair treatment composition (whether 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 seconds or 1, 2, 5, 10, or 20 minutes before or after a shampoo and/or conditioner is (either) applied. to hairs.

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 sub-ranges between them. Thus, a range of 1 to 5, specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc. .

All components and elements positively specified in this disclosure may be negatively excluded from the claims. In other words, the hair treatment compositions of this disclosure may be free or substantially free of all components and elements positively cited throughout this disclosure. In some cases, the hair treatment compositions of the present disclosure may be substantially free of non-incidental amounts of the ingredient(s) or compound(s) described herein. A non-incidental amount of an ingredient or compound is the amount of that ingredient or compound which is added to the hair treatment composition by itself. For example, a hair treatment composition may be substantially free of a non-incidental amount of an ingredient or compound, although such ingredient(s) or compound(s) may be present. ) as part of a raw material that is included as a mixture of two or more compounds.

The term "substantially free" or "substantially free" as used herein means that there is less than about 2% by weight of a specific material added to a composition, based on the total weight of the compositions. However, the compositions may include less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, or none of the specified material. All components specified herein may be optionally included or excluded from the compositions/methods/kits. When excluded, compositions/methods/kits may be free or substantially free of the component. For example, a particular composition may be free or substantially free of silicones.

Some of the various component categories identified may overlap. In such cases where an overlap may exist and the hair treatment 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, some compounds can be characterized as both an emollient and a fatty compound. If a particular hair treatment composition includes both an emollient and a fatty compound, compounds that can be characterized as both an emollient and a fatty compound will serve only as an emollient or a fatty compound - not both.

All publications and patent applications cited in the specification are hereby incorporated by reference, for all intents and purposes, as if each 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 shall control.

As used herein, the terms "comprising", "having" and "including" are used in their broad, non-limiting sense. The terms "a" "an" and "the" and "the" are understood to include the plural as well as the singular. Thus, the term "any of their mixtures" also refers to "mixtures thereof". Throughout the disclosure, the term "one of their mixtures" is used, following a list of elements as shown in the following example where the letters A through 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 phrase, "one of their mixtures" 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 could be included). Rather, it indicates that a mixture of any two or more 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 any two or more of A, B, C, D, E, and F”.

The term "one or more" means "at least one" and thus includes individual components as well as mixtures/combinations. Other than in the working examples, where unless otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions can be modified in all cases by the term "approximately" meaning within +/- 5% of the number noted.

The term "treating" (and grammatical variations thereof) as used herein refers to the application of the compositions of the present disclosure to the surface of keratinous substrates such as the hair on the head and/or body of a user. .

EXAMPLES

An implementation of this disclosure is provided using the following examples. The following examples serve to elucidate aspects of the technology without being limiting in nature.

Example 1

Example 2

Example Composition E was evaluated in comparison to Comparative Composition 1. The formulation for Comparative Composition 1 is provided below in the table below.

Example Composition E and Comparative Composition were applied to 1 to 10 volunteers with hair type sensitivity 3 to 5 (medium to high damage hair). Each of the volunteers had washed their hair with shampoo, rinsed, and to remove any excess water before application of Example Composition E and Comparative Composition 1. Example Composition E was applied to one half of the hair on each volunteer's head while Comparative Composition 1 was applied to the other half of the hair on each volunteer's head.

During application of the hair treatment compositions, Example Composition E exhibited a significantly higher melting feel, slightly higher absorption, significantly higher detangling, and flexibility compared to Comparative Composition 1. However, , Example Composition E was slightly less tacky than Comparative Composition 1.

After rinsing the hair of each of the volunteers, Example Composition E exhibited slightly better disentangling, combing, suppleness, and smoothness compared to Comparative Composition 1 for the evaluation of the results on wet hair. Comparative Composition 1, however, exhibited slightly better wet lift and slightly better individualized and massaging effect than Example Composition E for wet results.

The hair of each volunteer was subsequently dried using a hair dryer and assessed. Example Composition E exhibited slightly better straight hair (visual and tactile) and slightly improved dryness and dry ends compared to Comparative Composition 1. Example Composition E exhibits slightly higher hair weight and Slightly higher amount of coating, but slightly less bulk and clean hair feel compared to Comparative Composition 1 for results on dry hair.

Example 3

The viscosity versus shear rate of Example Compositions E and F and Comparative Compositions 1 and 2 was evaluated under neat and diluted conditions. The formulation for Comparative Composition 2 is provided below in Table 3.

Under undiluted conditions, samples of Example Compositions E and F and Comparative Compositions 1 and 2 were tested using a Discovery HR-2 TA Instrument Rheometer. For dilute conditions, dilute samples were prepared by combining each of Example Compositions E and F and Comparative Compositions 1 and 2 with water in a weight ratio of (1:1.5) and tested using a Discovery HR-2 TA instrument. Figures 1 through 4 provide graphs of the viscosity of undiluted and diluted samples of Example Compositions E and F and Comparative Compositions 1 and 2 as a function of shear rate.

As seen in Figures 1 and 2, the viscosity versus shear rate of the diluted samples of Example Compositions E and F was significantly lower than the viscosity versus shear rate of the undiluted samples of the Example Compositions E and F. The decrease in viscosity due to dilution, which mimics application to wet hair and/or external water addition, is associated with the unique melting sensation imparted by the Example Compositions hair treatment of the present disclosure. As noted in Example 2, above, Example E composition exhibited a significantly higher melt feel.

Comparative Compositions 1 and 2, however, exhibited similar viscosity versus shear rate for undiluted and diluted samples ( see Figures 3 and 4). Thus, Example Compositions E and F exhibited a surprising change in viscosity behavior after dilution.

Example 4

Example Compositions E and F and Comparative Compositions 1 and 2 were assessed to determine the uniformity of deposit coverage on medium-lightened locks of hair using PARK SYSTEMS NX10 atomic force microscopy. The locks of moderately lightened hair were washed with a standard shampoo before application of the compositions of example E and F and comparative compositions 1 and 2. The locks were then rinsed and dried. Figures 5 and 6 show images of the surface topography and stiffness of the hair after application of Example Compositions E and F and Comparative Compositions 1 and 2. The coverage uniformity for Example Compositions E and F was better. than for the two comparative compositions 1 and 2.
