Description

HAIR TREATMENT COMPOSITIONS COMPRISING AN ESTERQUAT

FIELD OF THE DISCLOSURE

The instant disclosure relates to hair treatment compositions that provide improved frizz control, style hold, and conditioning to hair.

BACKGROUND

Consumers style their hair and strive to keep the shape and appearance of the hair maintained for a prolonged period. Many styling products have been developed to“hold” a desired hairstyle ( e.g ., hairspray, etc.), but these products inevitably breakdown resulting in the shape and appearance of the hair deteriorating. As hair loses the desired shape, it often becomes frizzy, especially under high humidity conditions. Humidity is particularly problematic for dry, damaged, and curly hair.

Under high humidity conditions, more moisture is available to penetrate into hair and change the intermolecular interactions between proteins inside the hair fibers. During styling, the consumer will create a“wet set” where hair is blow dried or flat ironed to create the desired shape. Water evaporates from the hair during the drying process and hydrogen bonds form between protein chains holding the style in place. As moisture from the environment diffuses back into the hair, hydrogen bonds breakdown resulting in the hair returning to its natural shape. Also, the absorption of water causes the hair fibers to swell, thereby increasing the diameter of the hair fiber and promoting the development of frizz. For consumers with naturally curly hair who straighten their hair by blow drying or flat ironing, this return to a curled style is associated with a loss of alignment and increased volume.

A variety of different products have been developed to help reduce frizz and maintain better style and volume control. A typical control frizz is the use of leave-on products with surface-depositing materials such as film-formers, oils, conditioning materials etc. These materials make hair more hydrophobic and decrease inter-fiber interactions. At high levels, these materials can provide increased cohesive forces holding fibers together, which slows the development of frizz. However, the high levels required to control frizz make the hair appear greasy and weigh down the hair fibers. If used at low enough levels to avoid weighing down the hair and causing greasiness, the product is not sufficiently cohesive and therefore does not effectively control frizz. SUMMARY OF THE DISCLOSURE

The instant disclosure relates to hair treatment compositions that provide styling benefits to hair, such as anti-frizz properties, volume control, and conditioning. Unlike typically leave-on styling products that are not rinsed from the hair after styling, the instant hair treatment compositions are preferably rinsed from the hair prior to styling the hair. Although the hair treatment compositions are rinsed from the hair, the hair treatment compositions provide surprisingly long lasting frizz control, styling hold, and conditioning benefits to the hair. The hair treatment compositions do not weigh down the hair nor do they impart a greasy or tacky residue on the hair. Instead, the hair is soft, smooth, and natural looking.

The hair treatment compositions typically include:

(a) at least one first cationic surfactant that is an esterquat;

(b) at least one second cationic surfactant that is not an esterquat;

(c) at least one silicone oil;

(d) at least one fatty alcohol; and

(e) water.

Additionally, the hair treatment compositions may optionally include, for example, at least one nonionic polymer, at least one cationic polymer, at least one amino silicone, etc. The viscosity of the hair treatment compositions may be, for example from about 1700 mPa.s to about 4200 mPa.s; and the pH of the hair treatment compositions is typically less than 7, for example from about 3 to about 5.

The at least one first cationic surfactant that is an esterquat may be selected from the various esterquats known in the art. In some cases, however, a particularly useful esterquat is selected from compounds of formula (I):

wherein R1 and R2 are independently a saturated or unsaturated hydrocarbon moiety comprising 1 1 to 23 carbon atoms; and X- is a cosmetically acceptable counterion. A non-limiting and particularly preferred esterquat is bis- (isostearoyl/oleoyl isopropyl) dimonium methosulfate. The at least one second cationic surfactant, which is not an esterquat may be, for example, a quaternary ammonium compound that is a mono or double chain quaternary ammonium compound independently having about 14 to about 24 carbon atoms in each chain, and a cosmetically acceptable counterion, for example, a counterion selected from chloride, bromide, and methosulfate, preferably methosulfate.

The hair treatment compositions include at least one silicone oil. In some instances, it is preferable to include at least two silicone oils, for example, at least one silicone oil is having a viscosity of about 1 to 1000 centistokes and at least one silicone oil having a viscosity greater than 1000 to about 1 ,000,000 centistokes. Non-limiting examples of silicone oils include polyalkylsiloxanes, polyarylsiloxanes, polyalkarylsiloxanes, and polyestersiloxanes. Polyalkylsiloxanes such as dimethicone can be particularly useful.

The inventors discovered that the unique combination of esterquat(s), cationic surfactant(s) that is/are not an esterquats, and the silicone oil(s) in the hair treatment compositions contribute to the surprisingly long lasting frizz control, styling hold, and conditioning benefits provided by the hair treatment compositions. Use of additional, optional ingredients, such as nonionic polymers, cationic polymers, and/or amino silicones can further enhance the unique and beneficial cosmetic attributes provided by the hair treatment compositions.

The instant disclosure also encompasses methods for treating hair using the hair treatment compositions. The methods include, for example, methods for reducing or preventing frizz, methods for controlling volume and/or maintaining shape, methods for conditioning the hair, etc. The methods typically include applying an effective amount of a hair treatment compositions according to the instant disclosure to the hair. The hair treatment compositions may be allowed to remain on the hair for a period of time, for example, from about 10 seconds to about 10 minutes, and may be subsequently rinsed from the hair. The hair may further dried and styled, as desired. BRIEF DESCRIPTION OF THE FIGURES

Implementations of the present technology will now be described, by way of example only, with reference to the attached figures, wherein:

FIG. 2 provides pictures and a summary of findings relating to frizz and volume for hair swatches treated with inventive compositions according to the instant disclosure and comparative compositions.

It should be understood that the various aspects of the instant disclosure are certainly not limited to the examples and findings shown in the figures.

DETAILED DESCRIPTION OF THE DISCLOSURE

The instant disclosure relates to hair-treatment compositions and to methods for treating hair using the hair-treatment compositions.

The terms“comprising,”“having,” and“including” are used in their open, non-limiting sense.

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

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

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

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

Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions may be modified in all instances, especially in the claims, by the term“about,” meaning within +/- 5% of the indicated number.

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

The term“treat” (and its grammatical variations) as used herein refers to the application of the compositions of the present disclosure onto the surface of hair. The term ‘treat” (and its grammatical variations) as used herein also refers to contacting hair with the hair treatment compositions of the present disclosure.

The compositions described throughout this disclosure may be a“rinse-off” product. A "rinse-off" product refers to a composition such as a hair treatment composition that is rinsed and/or washed with water either after or during the application of the composition onto the hair, and before drying and/or styling the hair. At least a portion of the composition is removed from the keratinous substrate during the rinsing and/or washing process.

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

The term“substantially free” or“essentially 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. Nonetheless, the compositions may include less than about 1 wt.%, less than about 0.5 wt.%, less than about 0.1 wt.%, less than 0.01 wt.%, or none of the specified material.

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

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

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

Likewise, the term“a salt thereof” also relates to“salts thereof.” Thus, where the disclosure refers to“an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, and a mixture thereof,” it indicates that that one or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included.

The cosmetically acceptable counter-ions mentioned throughout the disclosure may include, for example, an alkali metal, alkaline earth metal, methylsulfate, or ammonium counter-ion. This list of counter-ions, however, is non-limiting.

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

"Conditioning" as used herein means imparting to one or more hair fibers at least one property selected from combability, moisture-retentivity, luster, shine, sliding and softness. The state of conditioning can be evaluated by any means known in the art, such as, for example, measuring, and comparing, the ease of combability or sliding of the treated hair and of the untreated hair in terms of frictional force (N), and consumer perception. It may also be determined as a measure of hydrophobicity, for example, by measuring the contact angle.

"Volatile", as used herein, means having a flash point of less than about

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

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

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

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

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

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

All publications, patent applications, and journal articles cited in this specification are herein incorporated by reference, and for any and all purposes, as if each individual publication were specifically and individually indicated to be incorporated by reference. In the event of an inconsistency between the present disclosure and any publications incorporated herein by reference, the present disclosure controls.

As already mentioned, the instant disclosure describes hair treatment compositions that provide styling benefits to hair, such as anti-frizz properties, volume control, and conditioning. The hair treatment compositions do not weigh down the hair nor do they impart a greasy or tacky residue on the hair. Instead, the hair is soft, smooth, and natural looking. The hair treatment compositions typically include:

(a) at least one first cationic surfactant that is an esterquat;

(b) at least one second cationic surfactant that is not an esterquat;

(c) at least one silicone oil;

(d) at least one fatty alcohol;

(e) water; and

(f) optionally, one or more of:

(i) at least one nonionic polymer;

(ii) at least one cationic polymer; and

(iii) at least one amino silicone.

First Cationic Surfactant (Esterquat)

The first cationic surfactant that is an esterquat may be selected from esterquats known in the art. Esterquats can be prepared, for example, by esterifying fatty acids, their methyl esters, or triglycerides with alkanolamines, followed by quaternization of the resultant esteramine with an alkylating agent. Non-limiting examples of esterquats include triethanol amine (TEA)-based esterquats and methyl diethanolamine (MDEA)- based esterquats.

In some instances, the esterquats are preferably selected from compounds of formula (I):

wherein R1 and R2 are independently a saturated or unsaturated hydrocarbon moiety comprising 1 1 to 23 carbon atoms; and X- is a cosmetically acceptable counterion. Non-limiting examples of cosmetically acceptable counterions include chloride, bromide, and methosulfate. In some instances, especially with respect to esterquats of formulta (i), methosulfate is a preferred counterion. By unsaturated hydrocarbon moiety is meant that the hydrocarbon radical comprises at least one carbon-carbon double bond (C=C) and/or at least one carbon- carbon triple bond. It can of course include several double and/or triple carbon-carbon bonds.

Preferably, R1 represents a hydrocarbon radical, saturated or unsaturated, linear or branched, comprising 13 to 21 carbon atoms, especially 15 to 19 carbon atoms, and especially 17 to 18 carbon atoms. When unsaturated, preferably R1 comprises at least one double bond (C=C), and in particular a single double bond, two double bonds or three double bonds.

Preferably, R2 represents a hydrocarbon radical, saturated or unsaturated, linear or branched, comprising 13 to 21 carbon atoms, especially 15 to 19 carbon atoms, and especially 17 to 18 carbon atoms. When unsaturated, preferably, R2 comprises at least one double bond (C=C), and in particular a single double bond, two double bonds or three double bonds.

Preferably, R1 and R2 comprise the same number of carbon atoms. Preferably, R1 and R2 are the same. Preferably, R2 represents an oleyl group. Preferably, R1 represents an oleyl or stearyl or isostearyl group. When unsaturated, preferably R1 comprises at least one double bond (C=C), and in particular a single double bond, two double bonds, or three double bonds.

According to a particular embodiment, R1 and R2 are both oleyl. According to another particular embodiment, R1 represents a stearyl group or an isostearyl group and R2 represents an oleyl group.

In some embodiments, the hair treatment compositions may include a mixture of esterquats of formula (I). In particular, the hair treatment compositions may include a mixture of esterquats of formula (I) in which R1 and R2 independently comprise 15 to 19, in particular 17 or 18, carbon atoms, and only one double bond, two double bonds or three double bonds.

In particular, the acyl groups (-C(0)R1 and -C(0)R2) may be derived from unsaturated carboxylic fatty acids which may comprise 12 to 24 carbon atoms, especially 14 to 22 carbon atoms, in particular 16 at 20 carbon atoms. Mention may be made of oleic acid, linoleic acid, and linolenic acid. The fatty acids may be of natural, plant or animal origin; in particular, they may be derived from vegetable oils, for example olein, rapeseed oil, soybean oil, sunflower oil, coconut oil or tall oil (pine oil).

The acyl group -C(0)R may also be derived from unsaturated carboxylic fatty acids which may comprise 12 to 24 carbon atoms, especially 14 to 22 carbon atoms, in particular 16 to 20 carbon atoms. Mention may be made of isostearic acid, palmitic acid and arachidic acid. The acyl group -C(0)R may also be derived from unsaturated carboxylic fatty acids which may comprise 12 to 24 carbon atoms, especially 14 to 22 carbon atoms, in particular 16 to 20 carbon atoms. Mention may be made of isostearic acid, palmitic acid and arachidic acid.

Preferably, X- is an anion of the halide (chloride, iodide or bromide), phosphate, acetate, lactate, sulfate or (C1 -C4) alkyl sulfate type, in particular methylsulphate or ethylsulphate; (C1 -C4) alkyl sulphonate or (C1 -C4) alkyl aryl sulphonate.

The compounds of formula (I) may be prepared by esterification of alkanolamines, and in particular of methyldiisopropanolamine (MDIA), and unsaturated carboxylic fatty acids, for example in a molar ratio ranging from 1 :1 .6 to 1 :2, the esterification being followed by a quaternization. The proportion of unsaturated fraction in these natural fatty acids can be adjusted so as to have an iodine number of between 40 and 160, especially between 80 and 150, which is the case for the vegetable oils mentioned above.

The esterification can be carried out by any known means, in particular in the presence of a catalyst such as methanesulfonic acid, preferably in an inert atmosphere (nitrogen for example), preferably at a temperature of 160-240°C. The quaternization can be carried out by any known means, for example in a solvent such as ethanol, isopropanol, propylene glycol or dipropylene glycol, preferably at a temperature of 60-90°C, by adding a quantity equimolar quaternizing agent, especially with stirring. Quaternizing agents that may be mentioned include organic or inorganic quaternizing agents such as short-chain dialkyl sulphates or phosphates, in particular dimethyl sulphate and dimethyl phosphate, or short-chain halogenated hydrocarbons such as methyl chloride. Such quaternary ammonium compounds are in particular described in US Patent No. 6,653,275, US20140286889, and European Patent No. EP240727, which are incorporated herein by reference in their entirety.

A particularly preferred esterquat is bis-(isostearoyl/oleoyl isopropyl) dimonium methosulfate commercially available as VARISOFT EQ 100.

Additional non-limiting examples of esterquats that may be useful include those of the formula below:

wherein R₄ is an aliphatic hydrocarbon group having from 8 to 22 carbon atoms; R2 and R3, are, each independently, (CH2)_S-R5, wherein Rs is an alkoxy carbonyl group containing from 8 to 22 carbon atoms, benzyl, phenyl, C1-C4 alkyl substituted phenyl, OH or H; R1 is (CH2)t-R6, wherein R6 is benzyl, phenyl, C1-C4 alkyl substituted phenyl, OH or H; q, s, and t are, each independently, an integer from 1 to 3; and X- is a cosmetically acceptable anion.

The total amount of the first cationic surfactant(s) (i.e., the esterquat(s)) can vary but is typically about 0.5 to about 10 wt.%, based on the total weight of the hair treatment composition. In some cases, the total amount of the first cationic surfactant(s) (i.e., the esterquat(s)) may be about 0.5 to about 8 wt.%, about 0.5 to about 6 wt.%, about 0.5 to about 5 wt.%, about 0.5 to about 4 wt.%, about 1 to about 10 wt.%, about 1 to about 8 wt.%, about 1 to about 6 wt.%, about 1 to about 5 wt.%, or about 1 to about 4 wt.%, based on the total weight of the hair treatment composition, including all ranges and subranges therebetween.

Second Cationic Surfactant (Non-Esterquat)

The second cationic surfactant(s) (i.e., the non-esterquats) may be selected from those known in the art. Non-limiting examples include quaternary ammonium-type cationic surfactants. In some instances, the second cationic surfactant(s) may be selected from mono and double chain quaternary ammonium compounds independently having from about 14 to about 24 carbon atoms in each chain, and a counterion selected from chloride, bromide, and methosulfate (preferably methosulfate). Non-limiting examples include cetrimonium chloride, cetrimonium methosulfate, stearimonium chloride, behentrimonium chloride, behentrimonium methosulfate, behenamidopropyltrimonium methosulfate, stearamidopropyltrimonium chloride, cetyltrimethylammonium chloride, cetyltrimethylammonium bromide, dipalmitoylethyl hydroxyethylmonium methosulfate, dicetyldimonium chloride, and a mixture thereof.

The total amount of the second cationic surfactant(s) in the hair treatment compositions can vary but is typically about 0.5 to about 10 wt.%, based on the total weight of the hair treatment composition. In some instances, the total amount of the second cationic surfactant(s) in the hair treatment composition may be about 0.5 to about 8 wt.%, about 0.5 to about 6 wt.%, about 0.5 to about 5 wt.%, about 0.5 to about 4 wt.%, about 1 to about 10 wt.%, about 1 to about 8 wt.%, about 1 to about 6 wt.%, about 1 to about 5 wt.%, or about 1 to about 4 wt.%, based on the total weight of the hair treatment composition, including all ranges and subranges therebetween.

Silicone Oil

The term“silicone oil” is interchangeable with the terms“polysiloxane” and “polysiloxane oil.” For purposes of the instant disclosure, “amino silicones” are not considered a“silicone oil.” Instead, amino silicones form an independent category of component that may optionally be included in the hair treatment compositions. A more detailed definition and non-limiting examples of amino silicones are provided later, under the heading“Amino Silicone.”

Non-limiting examples of silicone oils include polyalkylsiloxanes, polyarylsiloxanes, polyalkarylsiloxanes, polyestersiloxanes, polyphenylsiloxanes and a mixture thereof. In some instances, the silicone oil is preferably water insoluble at room temperature.

Representative examples of non-volatile, non-phenyl silicone oils which may be mentioned include polydimethylsiloxanes; alkyl dimethicones; vinylmethyl methicones; and also silicones modified with aliphatic groups. It should be noted that "dimethicone" (INCI name) corresponds to a poly(dimethylsiloxane) (chemical name), which is particularly preferred in some instances. The silicone oils are preferably chosen from non-volatile dimethicone oils. In particular, these oils can be chosen from the following non-volatile oils:

polydimethylsiloxanes (PDMSs),

PDMSs comprising aliphatic groups, in particular alkyl or alkoxy groups, which are pendent and/or at the end of the silicone chain, these groups each comprising from 2 to 24 carbon atoms. By way of example, mention may be made of the cetyl dimethicone sold under the commercial reference Abil Wax 9801 from Evonik Goldschmidt,

PDMSs comprising aliphatic groups, or functional groups such as hydroxyl, thiol and/or amine groups,

polyalkylmethylsiloxanes substituted with functional groups such as hydroxyl and thiol groups,

polysiloxanes modified with fatty acids, fatty alcohols or polyoxyalkylenes, and mixtures thereof.

Preferably, non-volatile and non-phenyl silicone oils are chosen from polydimethylsiloxanes; alkyl dimethicones and also PDMSs comprising aliphatic groups, in particular C2-C24 alkyl groups.

The silicone oil may be chosen from silicones of the following formula:

in which:

Ri , R2, R5 and R6 are, together or separately, an alkyl radical containing 1 to 6 carbon atoms,

Rs and R₄ are, together or separately, an alkyl radical containing from 1 to 6 carbon atoms, a vinyl radical, or a hydroxyl radical,

X is an alkyl radical containing from 1 to 6 carbon atoms, or a hydroxyl radical n and p are integers chosen so as to have a fluid compound, in particular of which the viscosity at 25°C is between 1 centistokes (cSt) and 1 ,000,000(cSt).

As non-volatile non-phenyl silicone oils which can be used according to the invention, mention may be made of those for which:

the substituents Ri to Fte and X represent a methyl group, and p and n are such that the viscosity is 500 000 cSt, for example the product sold under the name SE30 by the company General Electric, the product sold under the name AK 500000 by the company Wacker, the product sold under the name Mirasil DM 500 000 by the company Bluestar, and the product sold under the name Dow Corning 200 Fluid 500 000 cSt by the company Dow Corning,

the substituents Ri to R6 and X represent a methyl group, and p and n are such that the viscosity is 60 000 cSt, for example the product sold under the name Dow Corning 200 Fluid 60 000 CS by the company Dow Corning, and the product sold under the name Wacker Belsil DM 60 000 by the company Wacker,

the substituents Ri to R6 and X represent a methyl group, and p and n are such that the viscosity is 100 cSt or 350 cSt, for example the products sold respectively under the names Belsil DM100 and Dow Corning 200 Fluid 350 CS by the company Dow Corning,

the substituents Ri to R6 represent a methyl group, the group X represents a hydroxyl group, and n and p are such that the viscosity is 700 cSt, for example the product sold under the name Baysilone Fluid TO.7 by the company Momentive.

In some embodiments, it is preferable that the hair treatment compositions include two or more silicone oils, for example, two or more silicone oils selected from polyalkylsiloxanes, polyarylsiloxanes, polyalkarylsiloxanes, polyestersiloxanes, and a mixture thereof. In some instances, the two or more silicone oils are preferably two or more silicone oils selected from polyalkylsiloxanes ( e.g ., dimethicones). It is especially useful to include two or more silicone oils wherein at least one silicone oil has a viscosity of about 1 to 1000 centistokes and at least one silicone oil has a viscosity greater than 1000 to about 1 ,000,000 centistokes at 25°C. Centistokes is a standard unit used in the silicone industry for characterizing silicone oils because it is a representation of cinematic viscosity, which provides a better description of the behavior of silicone oils, as opposed to a dynamic viscosity (often represented by mPa.s). The viscosity of the silicone oils can be determined by methods known in the art, for example, using the Stokes viscosity or even a rotational viscometer.

The silicone oils having a viscosity of about 5 to 1000 cSt, may also have a viscosity of about 50 to about 1000 cSt, about 100 to about 1000 cSt, about 50 to about 750 cSt, about 100 to about 750 cSt, about 50 to about 500 cSt, about 100 to about 500 cSt, about 150 to about 500 cSt, about 200 to about 500 cSt, or about 350 cSt, including all ranges and subranges therebetween.

The total amount of silicone oil(s) in the hair treatment compositions having a viscosity of about 5 to 1000 cSt can vary but is typically about 0.1 to about 10 wt.%, based on the total weight of the hair treatment composition.

Implementation of the present disclosure is provided by way of the following examples. The examples serve to illustrate certain aspect of the technology and do not limit or constrain the disclosure.

EXAMPLE 1

(Compositions)

¹ BIS-(ISOSTEAROYL/ OLEOYL ISOPROPYL) DIMONIUM METHOSULFATE has the tradename VARISOFT EQ 100, and is available from the supplier EVONIK GOLDSCHMIDT EXAMPLE 2

(Contribution of Esterquat -Wet Frictional Force)

Testing was carried out to determine the influence of an esterquat in hair treatment compositions. Comparative Composition X of Example 1 is identical to Inventive Composition A of Example 1 , except that Comparative Composition X does not include an esterquat. Medium bleached Caucasian hair swatches that weighed 1 gram and were 27 cm long were treated with either Comparative Composition X or Inventive Composition A, according to the following protocol. Comparative Composition X or Inventive Composition A was applied to hair swatches. After rinsing the hair swatches with water, the hair swatches were subjected to instrumental testing using a sliding machine to determine the mean frictional force. The mean frictional force is a measurement of the smoothness and slipperiness of hair. Less frictional force indicates that there are less up-lifted cuticle due the neutralization of free anionic charges by the cationic surfactant. The hair is therefore perceived by consumers as a smoother and slipperier hair (more conditioned).

A sliding machine measures the force needed to make a hair swatch slide between 2 others. The average force is calculated and the evolution of the sliding force is recorded to quantify the surface state (homogeneous or heterogeneous) along the swatch. The more homogeneous the surface, the smoother the hair and therefore the less force is required for sliding. The results are presented in the table below and are graphically presented in FIG. 1 .

The data show that treatment with Inventive Composition A provided a statistically lower mean frictional force than treatment with Comparative Composition X. This illustrates that compositions containing an esterquat in the compositions of the instant disclosure provide significantly better conditioning properties to hair (e.g., smoothness and slipperiness) compared to compositions without an esterquat. EXAMPLE 3

(Contribution of Silicone Oils - Frizz)

Testing was carried out to determine the influence of various silicone oils in the hair treatment compositions of the instant disclosure. Inventive Composition B in the table below is identical to Inventive Composition B in Example 1 . Inventive Composition B-1 is identical to Inventive Composition B except that is includes lower amounts of silicone oils than Inventive Composition B. Comparative Composition X-1 does not include silicone oils. Comparative Compositions X-2 and X-3 each include an aminosilicone (amodimethicone or silicone quaternium-22). Comparative Composition X-4 includes only one silicone oil, which had a viscosity of greater than 1000 to about 1 ,000,000 cSt (dimethicone (60,000 CST))

tradename VARISOFT EQ 100, and is available from the supplier EVONIK GOLDSCHMIDT. Medium bleached Caucasian hair swatches that weighed 1 gram and were 27 cm long were treated with the compositions presented in the table above, according to the following protocol. The compositions were applied to the hair swatches, rinsed with water, and allowed to dry at room temperature for 24 hours (about 23°C and about 58% relative humidity).

After 24 hours, the hair swatches were photographed and visually evaluated by experts to determine fizziness. Photographs and characterizations of the hair swatches are presented in FIG. 2. The hair swatches treated with Inventive Composition B and Inventive Composition B-1 exhibited the least amount of frizz (low frizz and medium frizz). The hair swatches treated with Comparative Compositions X-1 , X-2, X-3, and X-4 exhibited high frizz.

EXAMPLE 4

(Contribution of Cationic Polymer - Wet Frictional Force)

Testing was carried out to determine the influence of a cationic polymer in hair treatment compositions. Inventive Compositions B and H were tested. Inventive Composition B does not include a cationic polymer and Inventive Composition H does (polyquaternium- 10).

Medium bleached Caucasian hair swatches that weighed 1 gram and were 27 cm long were treated with either Inventive Composition B or Inventive Composition H , according to the following protocol. Inventive Compositions B or H were applied to the hair swatches, rinsed with water, and subjected to instrumental testing using a sliding machine to determine the mean frictional force. The mean frictional force is a measurement of the smoothness and slipperiness of hair. Less frictional force indicates that the hair is smoother and slipperier (more conditioned).

A sliding machine measures the force needed to make a hair swatch slide between 2 others. The average force is calculated and the evolution of the sliding force is recorded to quantify the surface state (homogeneous or heterogeneous) along the swatch. The more homogeneous the surface, the smoother the hair and therefore the less force is required for sliding. The results are presented in the table below.

The data show that treatment with Inventive Composition H, which includes a cationic polymer (polyquaternium-10) resulted in a significantly lower frictional force. This illustrates that invention compositions containing cationic polymers provide significantly better conditioning properties to hair ( e.g ., smoothness and slipperiness) than without the cationic polymer.

EXAMPLE 5

(Contribution of Nonionic Polymer - Wet & Dry Frictional Force) Testing was carried out to determine the influence of nonionic polymers in the hair treatment compositions of the instant disclosure. Inventive Compositions B and E were tested. Inventive Composition B does not include a nonionic polymer and Inventive Composition E does (hydroxypropyl starch phosphate).

Medium bleached Caucasian hair swatches that weighed 1 gram and were 27 cm long were treated with either Inventive Composition B or Inventive Composition E, according to the following protocol. Inventive Compositions B and E were applied to hair swatches, the hair swatches were rinsed with water, and subjected to instrumental testing using a sliding machine to determine the mean frictional force while wet. The hair swatches were then allowed to dry at room temperature for 24 hours (about 23°C and about 58% relative humidity) and were again subjected to instrumental testing to determine the mean frictional force while dry. The mean frictional force is a measurement of the smoothness and slipperiness of hair. Less frictional force indicates that the hair is smoother and slipperier (more conditioned).

The data show that hair swatches treated with Inventive Composition E, which included a nonionic polymer (hydroxypropyl starch phosphate), exhibited a significantly lower frictional force. This illustrates that invention compositions containing nonionic polymers provide significantly better conditioning properties to hair ( e.g ., smoothness and slipperiness) than without nonionic polymers, especially with respect to wet hair.

EXAMPLE 6

(Performance Testing)

Inventive Compositions B-H were subjected to salon testing and to wet and dry frictional force testing described above in Examples 5 and 6. For the salon testing, 6 volunteers were treated with Inventive Compositions B-H on half the head of hair. The other half of the head of hair was treated with a reference composition. After treatment, experts evaluated the condition of the hair (wet and dry) for a variety of cosmetic attributes. If a composition performed better than the reference composition for a particular cosmetic characteristic, this is shown with a“+”.

A consumer study on the hair of 32 volunteers was also conducted to test the invention compositions B and E and attributes of softness, hydration, perception of immediate repair, and shine were observed.
