Description

COSMETIC COMPOSITIONS CAPABLE OF FORMING AN EMULSION

Field of the Disclosure

The instant disclosure is related to cosmetic compositions capable of forming an emulsion, and particularly those forming an emulsion in situ upon combination with extraneous water. The instant disclosure also relates to methods for using the cosmetic compositions.

Background of the Disclosure

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 conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point oils, silicone compounds, and mixtures thereof. Most of these conditioning agents are known to provide various conditioning benefits.

However, there is still a need for developing new and improved formulations and methods of treating hair for providing improved hair manageability, for example, improved hair alignment, reduced unwanted volume (especially reduced frizz), and increased shine.

Summary of the Disclosure

The instant disclosure relates to cosmetic compositions that provide a unique sensorial and consumer experience by forming an emulsion with increased viscosity upon the addition (e.g., combination) of extraneous water and, in particular, forming an emulsion with increased viscosity in situ on wet hand(s), wet hair, etc. The cosmetic compositions are typically translucent or transparent prior to combination with extraneous water and are opaque or substantially opaque after combination with extraneous water. In addition to the unique functional properties of the cosmetic compositions during use, treatment of hair with the cosmetic compositions results in improved manageability, long-lasting style and frizz control, and smoothness.

The cosmetic compositions typically include:

a) about 20 to about 88 wt.% of one or more polyols chosen from ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, pentylene glycol, diethylene glycol, dipropylene glycol, 1 ,3 propanediol, glycerin, diglycerin, and a mixture thereof;

b) about 5 to about 50 wt.% of one or more monoalcohols having from 2 to 6 carbon atoms;

wherein the weight ratio of polyols to monoalcohols (total polyols : total monoalcohols) is from 20:1 to 0.5:1 ;

c) about 2 to about 5 wt.% of two or more cationic surfactants; d) about 4 to about 18 wt.% of one or more fatty compounds chosen from fatty alcohols, fatty acids, or a mixture thereof;

The compositions can also be applied on hair immediately after shampooing and conditioning the hair, for example, as a mask rinse-off or leave-in treatment. The compositions can also be applied before shampooing the hair as pre-treatment compositions. Moreover, the compositions are applied to wet or damp 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.

Detailed Description of the Disclosure

The cosmetic compositions of the instant disclosure provide a unique sensorial experience by forming an emulsion with increased viscosity during use. During use, a user combines the cosmetic composition with extraneous water ( e.g ., water other than the water already included in the cosmetic composition). This results in the formation of the emulsion with increased viscosity. The cosmetic compositions are typically solubilized and transparent (or translucent) prior to use when the cosmetic composition is combined with extraneous water. As the cosmetic composition becomes mixed with extraneous water, the viscosity of the composition increases, an emulsion forms, and the composition becomes opaque. This can occur, for example, when a consumer applies the cosmetic composition to a wet or damp part of the body ( e.g ., hands, face, skin, hair, etc.). The user may then physically manipulate the applied cosmetic composition (for example, by rubbing the hands together or rubbing the composition against another part of the body such as the face, hair, etc.). The cosmetic composition combines with the extraneous water in situ and forms an opaque emulsion having a higher viscosity than the cosmetic composition prior to combination with extraneous water.

The cosmetic compositions typically include:

The cosmetic composition is typically a solubilized, transparent composition having a viscosity of about 1 mPa.S to about 40 mPa.S at 25°C until combined with extraneous water (/.e., water other than the water of component g)). When combined with the extraneous water, the cosmetic composition forms an opaque emulsion in situ, which typically has a viscosity that is greater than that of the solubilized, transparent composition prior to combination with the extraneous water.

As used herein, the term "transparent” refers to a cosmetic composition having a 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, e.g., a transmittance of at least 80%, at least 90%, or at least 95% at a wavelength of 600 nm, measured, e.g., using a Lambda 40 UV-visible spectrometer. As used herein, the term "opaque” refers to a cosmetic composition having a transmittance of below 80% at a wavelength of 600 nm, for example measured using a Lambda 40 UV-visible spectrometer.

The cosmetic compositions typically combine with water to form an emulsion with increased viscosity. For example, the cosmetic composition may have a viscosity of about 1 mPa.s to about 40 mPa.s at a temperature of 25°C using a Rheomat® viscosimeter (spindle #3) at 200 revolutions per minute (RPM) prior to combination with extraneous water. After combination with extraneous water, the viscosity may be, for example, about 5 mPa.s to about 40,000 mPa.s at a temperature of 25°C using a Rheomat® viscosimeter (spindle #3) at 200 revolutions per minute (RPM). In some instances, the viscosity of the cosmetic composition prior to combination with extraneous water is about 1 mPa.s to about 30 mPa.s, about 5 mPa.s to about 40 mPa.s, or about 5 mPa.s to about 30 mPa.s. After combination with extraneous water, the viscosity may be, for example, about 5 mPa.s to about 40,000 mPa.s, about 10 mP.s to about 40,000 mPa.s, about 40 mP.s to about 40,000 mPa.s, about 50 mP.s to about 40,000 mPa.s, about 100 mPa.s to about 40,000 mPa.s, about 500 mPa.s to about 40,000 mPa.s, about 1 ,000 mPa.s to about 40,000 mPa.s, about 5,000 mPa.s to about 40,000 mPa.s, about 5 mPa.s to about 30,000 mPa.s, about 5 mPa.s to about 25,000 mPa.s, about 50 mPa.s to about 25,000 mPa.s, about 100 mPa.s to about 25,000 mPa.s, or about 500 mPa.s to about 20,000 mPa.s, including all ranges and sub-ranges therebetween.

The cosmetic composition form an opaque emulsion upon combination with extraneous water, for example, from a user’s wet or damp hands, wet or damp hair, and/or from the faucet and the like. The opaque emulsion may be formed by combining extraneous water with the cosmetic composition in an ratio (water : composition) ranging from 0.1 : 1 to 3 :1 , preferably 0.5 : 1 or 1 : 1 or 1.5 : 1 or 2 : 1 . Additionally and/or alternatively, the opaque emulsion may be formed by combining extraneous water in an amount such that the total amount of water in the cosmetic composition increases to more than 10 wt.% or, in some instances, to 12 wt.% or more, 15 wt.% or more, 20 wt.% or more, 25 wt.% or more, or 30 wt.% or more, relative to the amount of water in the cosmetic composition before combination with extraneous water.

The opaque emulsion formed from the combination of the cosmetic composition and extraneous water may occur without active mixing from a user or in conjunction with active mixing from the user. For example, in some instances, the opaque emulsion is formed automatically without the need for mixing. In other words, the cosmetic composition becomes sufficiently combined with extraneous water to form the opaque emulsion by simply coming into contact with extraneous water. In some instances, however, a minimal amount of mixing may be needed, and may be encouraged, to more thoroughly form the opaque emulsion. This can easily be achieved during use of the cosmetic composition, for example, by physically manipulating ( e.g ., mixing) the cosmetic composition with extraneous water using the body {e.g., with the hands).

This can occur, for example, when a consumer applies the cosmetic composition to a wet or damp part of the body {e.g., hands, face, skin, hair, etc.). The user may then physically manipulate the applied cosmetic composition (for example, by rubbing the hands together or rubbing the composition against another part of the body such as the face, hair, etc. or using an applicator or device to mix or physically manipulate the cosmetic composition with extraneous water). In at least one embodiment, the cosmetic composition combines with the extraneous water in situ and forms an opaque emulsion having a higher viscosity than the cosmetic composition prior to combination with extraneous water.

In some instances, upon combination with extraneous water, the cosmetic composition forms an emulsion having a lamellar phase, and may even form a multi-lamellar emulsion. In some instance, upon combination with extraneous water, the cosmetic composition forms an emulsion comprising emulsified droplets, micelles, etc. 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. In some instances, the cosmetic composition is formulated to form the opaque emulsion within 3 minutes of combination (with or without active mixing) with water, preferably in 2 minutes or less, preferably in 1 minute or less, preferably in 45 seconds or less, preferably in 30 seconds or less, preferably in 20 seconds or less, preferably in 10 seconds or, or preferably in 5 seconds or less.

Suitable components, such as those listed below, may be included or excluded from the formulations for the hair cosmetic compositions depending on the specific combination of other components, the form of the cosmetic compositions, and/or the use of the formulation (e.g., a lotion, gel, cream, spray, etc.).

Water

The cosmetic composition typically includes 10 wt.% or less of water. For example, the amount of water present in the cosmetic composition prior to combination with extraneous water is typically 10 wt.%, 10 wt.% or less, 9 wt.% or less, 8 wt.% or less, 7 wt.% or less, 6 wt.% or less, 5 wt.% or less, 4 wt.% or less, 3 wt.% or less, 2 wt.% or less, 1 wt.% or less, or 0.5 wt.% or less, based on the total was of the cosmetic composition. In some instances, the water present in the cosmetic 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 cosmetic composition as part of a raw material that is included in the cosmetic composition. Although the cosmetic composition may include water prior to the combination of extraneous water, in some embodiments the cosmetic composition is anhydrous or substantially anhydrous.

Triglvceride(s)

The cosmetic composition may optionally include triglycerides in an amount typically ranging from about 0.1 to about 20 wt.%, based on the total weight of the cosmetic composition. The amount of triglycerides present in the cosmetic composition may range from, e.g., about 0.1 to about 40 wt.%, about 0.1 to about 35 wt.%, about 0.1 to about 30 wt.%, about 0.1 to about 25 wt.%, about 0.1 to about 20 wt.%, about 0.1 to about 15 wt.%; about 0.5 to about 40 wt.%, about 0.5 to about 35 wt.%, about 0. 5 to about 30 wt.%, about 0.5 to about 25 wt.%, about 0.5 to about 20 wt.%, about 0.5 to about 15 wt.%; about 1 to about 40 wt.%, about 1 to about 35 wt.%, about 1 to about 30 wt.%, about 1 to about 25 wt.%, about 1 to about 20 wt.%, about 1 to about 15 wt.%; about 2 to about 40 wt.%, about 2 to about 35 wt.%, about 2 to about 30 wt.%, about 2 to about 25 wt.%, about 2 to about 20 wt.%, or about 2 to about 15 wt.%, including all ranges and sub-ranges therebetween, based on the total weight of the cosmetic composition.

The triglycerides may be chosen from natural triglycerides (e.g., having a plant origin) or synthetic triglycerides. The triglycerides may have 6 to 30 carbon atoms— such as, for instance, heptanoic or octanoic acid triglycerides, or alternatively, for example, sunflower oil, corn oil, soybean oil, marrow oil, grapeseed oil, sesame seed oil, hazelnut oil, apricot oil, macadamia oil, arara oil, castor oil, avocado oil, olive oil, rapeseed oil, coconut oil, wheatgerm oil, sweet almond oil, apricot oil, safflower oil, candlenut oil, coconut oil, camellina oil, tamanu oil, babassu oil and pracaxi oil, jojoba oil, and shea butter oil, and mixtures thereof. Additionally and/or alternatively, the triglycerides may be chosen from caprylic/capric/isostearic/adipictriglycerides, caprylic/capric/linoleictriglycerides, caprylic/caprictriglycerides, caprylic/capric/stearictriglycerides, glyceryltrilaurate/stearate, glyceryldi/tripalmitostearate, glyceryldi/tritristearate, caprylictriglyceride, caprylic/capric/laurictriglycerides, and mixtures thereof.

pH Adiuster(s)

The cosmetic composition may include one or more pH adjusters to increase or decrease the overall pH of the cosmetic composition. For example, one or more acids may be included to decrease the pH of the cosmetic composition. Examples of suitable acids for decreasing the pH of the cosmetic composition include, but are not limited to, citric acid, acetic acid, and the like. The cosmetic composition may include one or more bases, such as sodium hydroxide, potassium hydroxide and the like, to increase the pH of the cosmetic composition. Additional or alternative acids and bases that are suitable for adjusting the pH of the cosmetic composition are readily known to one of ordinary skill in the art.

The cosmetic composition may, desirably, have a pH of less than 7. For example, the cosmetic composition may have a pH of about 2 to less than 7, preferably about 2.5 to about 6 or about 3 to about 5.

The amount of the pH adjuster in the cosmetic composition may be based on the desired pH of the final cosmetic composition and/or product. For example, the total amount of the pH adjuster may range from about 0.05 to about 20 wt.%, based on the total weight of the composition. In some instances, the total amount of pH adjuster is from about 0.05 to about 15 wt.%, about 0.1 to about 10 wt.%, or about 0.12 to about 5 wt.%, including ranges and sub-ranges therebetween, based on the total weight of the composition.

The cosmetic compositions of the instant disclosure may be incorporated into a kit. For example, the kits may include at least one cosmetic 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 cosmetic compositions according the instant disclosure, a shampoo, a conditioner a mask, and/or other hair treatment product, all of which are separately contained. 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, bottles, and sprayable containers. 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 cosmetic composition according to the instant disclosure, and the other tube may include a composition to be used with the cosmetic 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”) mask or other hair treatment products.

Methods of Treating Hair

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

The methods may include applying an amount of the cosmetic composition onto the body, for example, onto one or both hands, onto the hair, onto the face, etc.. The body may already be wet or damp with extraneous water or extraneous water can be included after the cosmetic composition has already been applied to the body. The cosmetic composition and the extraneous water may optionally be mixed together on the body to facilitate formation of an opaque emulsion having an increased viscosity. Alternatively the cosmetic composition and extraneous water may be combined, and optionally mixed, prior to application to the body. For example, the cosmetic composition may be combined in a container, bowl, packaging, bottle, etc., and subsequently applied to the body after formation of the opaque emulsion.

In some instances, the methods include forming the opaque emulsion on the hands and subsequently applying the opaque emulsion to the hair. In other instances, the methods include forming an opaque emulsion directly on the hair. In yet other instance, the methods include forming an opaque emulsion other the face, or other parts of the body.

The cosmetic compositions and the emulsions formed by combination with water are useful for conditioning and/or managing the hair. The cosmetic compositions and the emulsions formed by combination of water 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.

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

In some cases, the cosmetic compositions are used in conjunction with additional hair-treatment compositions in a routine, for example, during an individual’s normal showering/bathing routine. The cosmetic 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 cosmetic 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 cosmetic composition are simultaneously applied to the hair during the cleansing or conditioning process and simultaneously rinsed from the hair. Alternatively, the cosmetic 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 cosmetic composition is also applied to the hair.

When used in conjunction with a shampoo and/or a conditioner, the cosmetic 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 (cosmetic composition of the instant disclosure : shampoo/conditioner, etc.).

The cosmetic 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 cosmetic composition to remain on the hair for an extended period of time. Conveniently, the cosmetic 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 cosmetic 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 cosmetic composition is not being mixed with another composition prior to application to the hair, the cosmetic composition may be applied to the hair immediately after or before the hair is 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 a few seconds or 1 , 2, 5, 10, or 20 minutes before or after a shampoo and/or a conditioner is applied to the hair.

The cosmetic compositions of the instant disclosure are unique in their ability to provide hair with improved manageability, shape/style, long-lasting style and frizz control, curl definition, curl retention, and smoothness. Accordingly, the instant disclosure relates to methods for treating hair, for example, for improving the manageability of hair, for imparting lasting style and frizz control, and for imparting smoothness. More specifically, the cosmetic compositions may be used in methods for conditioning the hair, providing curl definition to the hair, providing frizz control to the hair, improving ease of combability and detangling, and providing smoothness.

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.

Example 1

(Conditioning Compositions)

Example 2

(Comparative Testing)

Inventive Compositions A and B and Comparative Compositions G-J were applied to hair swatches and the resulting discipline and smoothness of the hair swatches evaluated. Each of the hair swatches was washed with the shampoo shown in Table 3 (below) before treatment with a composition of Example 1.

After shampooing, the wet hair swatches were treated with compositions of Example 1 (Inventive Compositions A and B, and Comparative Compositions G, H, I, J, and K), as shown in the Figure 1 (~1 grams per swatch). The compositions were uniformly applied to the hair swatches using the hands and allowed to remain on the hair swatches for about 3 minutes. Inventive Compositions A and B came creamy and had a milky (opaque) appearance. Of the comparative formulations, only Comparative Composition H became creamy and had a milky (opaque) appearance. After 3 minutes, the hair swatches were rinsed, and maintained at ambient conditions (about 25°C) for 12 hours.

The hair swatches were then evaluated for discipline and smoothness. The discipline and smoothness of the hair swatches were evaluated on a scale from 1 to 5, with a value of 1 representing the best discipline/smoothness and a value of 5 representing the worst discipline/smoothness. As illustrated in the Figure 1 , the swatches treated with Inventive Compositions A and B exhibited the best results for both discipline and smoothness. Although the hair swatches receiving Inventive Compositions A and B both have a value of 1 for discipline and for smoothness, the hair swatch treated with Inventive Composition B exhibited better discipline and smoothness than the hair swatch treated with Inventive Composition A. The Figure 1 also shows a hair swatch that was only shampooed with the shampoo of Table 3 (Composition K) and not treated with a conditioner of Example 1 , but otherwise subjected to the same protocol as the other swatches (maintained at ambient temperature for 12 hours and evaluated).
