HAIR COSMETIC COMPOSITIONS CONTAINING CATIONIC COMPOUNDS,

PANTHENOL, AND OILS

FIELD OF THE DISCLOSURE

The instant disclosure relates to hair cosmetic compositions that are particularly useful for improving the quality of hair, in particular, curly hair, and which can impart durable styling/shaping attributes to hair. Also disclosed are methods for using the hair cosmetic compositions.

BACKGROUND

Many consumers desire to use cosmetic and care compositions that enhance the appearance of keratinous substrates such as hair, e.g., by changing the color, style, and/or shape of the hair, and/or by imparting various cosmetic properties to hair, such as shine and conditioning. Many of the known compositions and processes for enhancing or preserving the appearance of hair involve chemical treatments to the hair.

The process of changing the color of hair, for example, can involve depositing an artificial color onto the hair which provides a different shade or color to the hair, and/or lifting the color of the hair, such as lightening the color of dark hair to lighter shades, which m requires the use of oxidizing agents.

Additionally, there are many techniques and compositions for styling or altering the shape of hair. For example, hair care products referred to as “hair relaxers” or “hair straighteners” can relax or straighten curly or kinky hair, including wavy hair. Straightening or relaxing the curls of very curly hair may increase the manageability and ease of styling of such hair. Compositions for permanent waving the hair will impart a curl or a wave to otherwise straight hair. Different types of compositions can be applied onto hair in order to change its shape and make it more manageable, such as alkaline and acidic compositions. Hair relaxers, straighteners, perms, and/or waves may either be applied in a hair salon by a professional or in the home by the individual consumer.

While dyeing or color lifting compositions can effectively alter the color of hair, and relaxing, straightening, perming, and waving compositions can effectively alter the shape of the hair, these chemical treatments can damage the hair fibers and/or irritate the scalp. Thus, in order to reduce or avoid damage to hair, as well as to improve the cosmetic performance of the compositions, different types of hair styling products have been developed by manufacturers that are aimed to help consumers achieve a desired look, including one or more of fuller hair, thicker hair, sleek and straight hair, frizz-free hair, and defined curls. These products are typically provided in forms that are applied after the shampooing and conditioning processes are completed.

Increasingly, consumers also seek hair products that have a natural look and feel, a light-weight feel, while imparting longer-lasting styling or shaping benefits to hair. Further, consumers seek products that offer multiple benefits, for example, combining frizz reduction and style hold with softening, elongation or lengthening effects while still providing good curl definition. Moreover, consumers desire hair products that can protect hair from external factors such as high humidity which causes the hair to become very frizzy, unmanageable, and lose its shape and style or such as mechanical or physical or other external stresses on hair.

One important property sought by consumers of such products is their ability to provide longer lasting style or shape to the hair; i.e. , a style or shape that lasts overnight or can easily be regained when the consumer wakes up with no or minimal reapplication of the styling product and/or with no or minimal manipulation of the hair to restyle or re shape the hair and/or with no utilization of mechanical or physical styling devices such as hair rollers, hair pins and clips, head bands, or head caps. Thus, many consumers seek hair products which have excellent style memory. While different technologies and products exist in the market for hair styling products, there is still a need for improvement in these areas as well as at the same time, the need to provide caring benefits that are not typically found in a styling product.

Thus, the object of this invention is related to a composition and method of treating hair utilizing hair compositions which will deliver both caring and styling/shaping benefits that are long lasting or durable and can be maintained overnight or when the hair is subjected to changes in the hair shape or style or configuration, and/or to disturbance of the hair fibers and/or to movement of the hair fibers as a result of sleeping or lying down and resting the head on a bed or other surface or the back part of a seat and/or as a result of wearing a head cap or cover. Such styling/shaping benefits are for example, curl definition, as frizz control, discipline, shape control/hold, softness, smoothness, shine, natural feel, hydration, and light weight feel.

The object of the invention is also to deliver all other styling benefits that curly haired consumers desire on a daily basis: curl definition, moisture, conditioning, hold, frizz control, curl/shape retention, curl pick up, moisture to curls, and not leaving the curls feeling greasy or stiff. The composition from such an invention can be applied on wet or damp hair using various techniques such as “wash and go” or “twist out” methods. “Wash and go” involves applying the product, section by section, to wet or damp hair and letting it air dry. The “twist out” method involves manipulating the curl pattern in order to provide elongation while maintaining other styling benefits. It can be done by applying the product on wet hair and twisting small sections of the hair and letting it air dry.

The invention is particularly useful for treating and providing the described properties to curly hair (of varying degrees of curl) and to wavy hair.

SUMMARY OF THE DISCLOSURE

It has surprisingly been found that compositions and methods of treating hair according to the present invention impart durable styling/shaping attributes, including curl definition, curl retention, curl pick up, frizz control, volume control, control/hold, discipline, as well as other cosmetic benefits such as fast/easy styling or shaping, hydration, moisture, and smoothness to the hair, while still providing a light weight feel and a clean feel (non-greasy, non-oily) to the hair. These attributes were achieved even after the hair treated with the composition of the invention was subjected to changes in the hair shape or style or configuration, and/or to disturbance of the hair fibers and/or to movement of the hair fibers as a result of sleeping or lying down and resting the head on a bed or other surface or the back part of a seat and/or as a result of wearing a head cap or cover for at least 30 minutes up to several hours or overnight.

Methods

Another aspect of the invention pertains to methods of using the hair cosmetic compositions described herein. The methods generally comprise applying any of the hair cosmetic compositions described to hair. The hair cosmetic compositions may be useful in a variety of settings, and either for chemically treated or untreated hair. Use on treated hair can include chemically relaxed/straightened hair or chemically dyed or bleached or lightened/highlighted hair. Use on hair may include as part of a shampoo, part of a conditioner or as a conditioner, as a pre-treatment, or after cleansing or conditioning or washing the hair as a leave-on treatment for styling/shaping the hair or caring for curly hair or as a leave-on or rinse-off mask treatment.

Methods of treating hair according to the disclosure may include applying a hair cosmetic composition of the instant disclosure to the hair (wet, damp, or dry hair), allowing the hair treatment to remain on the hair for a sufficient amount of time, and rinsing the hair cosmetic composition from the hair or allowing the hair treatment to be left on the hair as a leave-on product. The hair cosmetic composition may be applied to the hair before, during, or after other hair cosmetic compositions (e.g., a shampoo, a conditioner, a mask, a cream, a lotion, a gel, etc.).

Other methods of treating hair according to the disclosure involve a wash and go/braiding technique. Typically, the hair type on which this method is used is curly hair.

Other methods of treating hair according to the disclosure involve a twist out technique. Typically, the hair type on which this method is used is curly hair.

The hair cosmetic composition may be allowed to remain on the hair for a period of time, for example from about a few seconds (1 , 3, 5, or 10 seconds) to about 10, 20, or 30 minutes, or longer such as up to about one hour or up to about two hours or up to about three hours or up to about four hours or up to about five hours or up to about six hours or up to about seven hours or up to about eight hours or up to about 12 hours.

The hair cosmetic compositions may be useful for treating chemically treated hair.

Described above is the individual application of a hair cosmetic composition or the combined or layered application of a hair cosmetic composition with another composition. In some cases, a hair cosmetic composition is individually applied to the hair and also combined or layered with another composition that is also applied to the hair.

Kits

The hair cosmetic compositions of the instant disclosure may be incorporated into a kit. For example, the kits may include at least one hair cosmetic composition according to the instant disclosure. The kits may also include one or more hair cosmetic compositions (according the instant disclosure), a shampoo and/or a conditioner and/or a mask.

Implementation of the present disclosure is provided by way of the following examples. The examples serve to illustrate the technology without being limiting in nature.

EXAMPLES

The following Examples are intended to be non-restrictive and explanatory only. The ingredient amounts in the compositions/formulas described below are expressed in % by weight, based on the total weight of the composition.

Several formulas were produced having the ingredients as listed in the tables below. The balance of all formulas was water. Example I: Compositions

Table 1: Formulation Examples

Table 2 Formula Texture and Observations the Next Day After Overnight Test Process of making the invention composition:

The invention formula A was prepared according to the following process:

Overnight Test Protocols:

A. Swatch testing: Test hair swatches were first treated with a rinse-out shampoo followed by a rinse-out conditioner. The hair swatches were towel-dried and then treated with the inventive composition or a comparative composition. To mimic overnight use (tossing and turning when asleep), the swatches were turned and rubbed against each other and a towel for ten times. The swatches were then left in a humidity chamber for 12 hours at 25°C and 80% humidity.

B. Consumer testing:

Human female volunteers were instructed to follow their regular hair routine at night and then apply the invention/test formula to their hair. The women volunteers who were selected typically wash their hair at night, air dry or diffuse, and use leave-in styling products to achieve a curl end look at least 3x a week. Additional criteria of test subjects were of similar hair length, hair texture of normal to coarse, curl type of slightly curly to curly. They used the products at a minimum of 4-5 uses per product.

After their regular hair routine at night, the volunteers dispensed the desired amount of the invention/test formula (starting with a dime size and applying more as needed) in their hands, rubbed their hands together, and evenly applied the formula to damp or dry hair. They then styled their hair as they normally would before going to sleep.

Example Testing the Invention Against Comparative Formula C

Tests on hair swatches were conducted according to Protocol A above. The test swatches were first treated with a shampoo, followed by a conditioner. Three of the swatches were treated with Formula A and another three of the swatches were treated with Formula C. The test formulas were tested as leave-in products (no immediate rinsing). Figure 1 shows the performance of the test formulas on hair after overnight testing.

When comparing to invention to Formula C which also provides soft curls (soft to the touch), the inventors have observed that the invention formula provided significantly better frizz and volume control, as well as significantly better curl definition and curl retention.

Example III Consumer Testing

The invention formula was tested on the hair of women volunteers according to Protocol B above. The volunteers provided feedback on their perception of how the test formula performed on their hair.

Table 3: Results of the consumer test

The results in Table 3 above show that the inventors surprisingly discovered a combination of ingredients that resulted in compositions provided good styling and shaping hold, including curl definition, good frizz and volume control, and other cosmetic attributes to hair even when the hair was treated the night before with the invention formula and it was slept on overnight. For the attribute, “hair doesn’t fall flat overnight”, the rating was negative. However, while the product did not deliver volume during night, it still enabled consumers to fix their hair quickly in the morning because the volunteers did not have “big frizzy” hair in the morning, i.e. , the product delivered volume control and lasting frizz control to hair overnight which was a main objective of the study. For the attribute “lasting curl definition”, the rating of +/- shows that some volunteers may not necessarily be defining this attribute in the same way (either lasting through the night and through the next day or lasting only through the night).

Overall, the consumer perception was that upon getting up in the morning, the invention formula provided to the hair that was slept on the desired cosmetic benefits such as fast, easy styling in the morning, curl definition, lasting frizz control, conditioned, healthy appearance, natural and soft look, feelings of softness, smoothness, no product build-up, detangling, being moisturized, and being clean, consistent style, visually appealing appearance, and pleasant texture.

In summary, the examples above show that the inventors surprisingly discovered a combination of ingredients that resulted in compositions that when applied to hair provided good styling and shaping hold, including curl definition, good frizz and volume control, and other cosmetic attributes to hair even when the hair was slept on for several hours (whether at night or during the day).

The foregoing description illustrates and describes the invention. The disclosure shows and describes only the preferred embodiments but it should be understood that the invention is capable to use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concepts as expressed herein, commensurate with the above teachings and/or the skill or knowledge of the relevant art. The embodiments described herein above are further intended to explain best modes known by applicant and to enable others skilled in the art to utilize the disclosure in such, or other, embodiments and with the various modifications required by the particular applications or uses thereof. Accordingly, the description is not intended to limit the invention to the form disclosed herein.

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

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, if 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, or mixtures 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, or mixtures 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 counterion. This list of counterions, however, is non-limiting.

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

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

The term “lasting” or “long lasting” or “durable” as used herein means that the cosmetic attribute or effect was observed up to about 30 minutes or up to about one hour or up to about two hours, or up to about three hours or up to about four hours or up to about five hours or up to about six hours or up to about seven hours or up to about eight hours or up to about 12 hours or after an overnight period from the time the composition of the present disclosure was applied to hair on the head of a person and the hair was subjected to changes in the hair shape or style or configuration, and/or to disturbance of the hair fibers and/or to movement of the hair fibers as a result of sleeping or lying down and resting the head on a bed or other surface or the back part of a seat and/or as a result of wearing a head cap or cover for at least 30 minutes up to several hours or overnight.

Some of the various categories of components identified for the hair-treatment compositions 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 fatty acid may be defined as both a “fatty compound” and a “surfactant/emulsifier.” If a particular composition/product includes both a fatty compound component and an emulsifier component, a single fatty acid can serve as only a fatty compound or a surfactant/emulsifier (a single fatty acid does not serve as both the fatty compound and the surfactant/emulsifier).

All percentages, parts and ratios herein are based upon the total weight of the compositions of the present invention, 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 points 1 , 2, 3, 4 and 5, as well as sub-ranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.; and points of 1 , 2, 3, 4, and 5 includes ranges and sub-ranges of 1-5, 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 understood to be modified by “about,” whether or not expressly stated. Additionally, all numbers are intended to represent exact figures as additional embodiments, whether or not modified by “about.” For example, “an amount of about 1 %” includes an amount of exactly 1 %. As a further example, “an amount of 1 %” includes an amount of about 1 %. The term “about” is generally understood to encompass a range of +/- 10% from the stated number, and is intended to cover amounts of +/- 1 %, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, and 10%.

The term “surfactants” includes salts of the surfactants even if not explicitly stated. In other words, whenever the disclosure refers to a surfactant, it is intended that salts of the surfactant are also encompassed 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 every instance throughout the disclosure), for example, by using language such as “a salt thereof” or “salts thereof.” Sodium and potassium are common cations that form salts with surfactants. However, additional cations such as ammonium ions, or alkanolammonium ions such as monoethanolammonium or triethanolammonium ions, may also form salts of surfactants.

The term “substantially free” or “essentially free” as used herein means the specific material may be present in small amounts that do not materially affect the basic and novel characteristics of the claimed invention. For instance, 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 an amount of less than 2% by weight does not materially affect the basic and novel characteristics of the claimed invention. Similarly, the compositions may include less than 2 wt%, less than 1 .5 wt%, less than 1 wt%, less than 0.5 wt%, less than 0.1 wt%, less than 0.05 wt%, or less than 0.01 wt%, or none of the specified material. Furthermore, all components that are positively set forth in the instant 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 set forth in the instant disclosure.

The term “substantially free” or “essentially 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.

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.
