Description

Hair conditioning composition containing hydrophobically modified cationic cellulose

technical field

The present invention relates to a hair conditioning composition comprising hydrophobically modified cationic cellulose.

Background of the invention

Human hair can become soiled due to contact with the surrounding environment and due to the sebum production of the scalp. Dirty hair gives it a dirty look and is not aesthetically pleasing. Dirty hair needs frequent shampooing.

Shampoo cleanses hair by removing excess dirt and sebum. But shampooing leaves hair in a damp, tangled, and generally unmanageable state. Once the hair dries, it is often left dry, rough, dull or frizzy due to the removal of its natural oils and other natural conditioning and moisturizing ingredients. In addition, it also results in high static levels in the hair when drying, which interferes with combing and leads to a condition commonly referred to as "flyaway hair", or undesirable "split ends", especially with long hair .

Various methods have been developed to condition hair. These methods range from applying hair conditioners after shampooing, such as leave-on and rinse-off products, to hair conditioning shampoos which attempt to cleanse and condition the hair with the same product.

While some consumers prefer light and convenient shampoos with conditioners, a significant percentage prefer more conventional conditioner products. These products are separate from shampooing and are usually applied to the hair after shampooing. Conditioning compositions may be rinse-off or leave-on products, and may be lotions, creams, gels, sprays and mousses. Such consumers, who prefer conventional conditioner products, value high conditioning benefits, or the convenience of varying the amount of conditioning depending on the condition or size of the hair.

One conventional method by which conditioning benefits can be provided to the hair is through the use of hair 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 such as moisturization, softness and static control of the hair, but also weigh down the hair and leave the hair sticky or feel greasy or waxy.

Hair conditioning compositions comprising the above conditioning agents can provide conditioning benefits such as soft and moisturized feel on dry hair, but it also weighs down the hair. The weighed down hair creates the appearance of a reduced bulk hair volume. For consumers who want a volume-up of their hair, such as those with fine hair, they do not want a hair weighing effect. As used herein, the term "full hair" does not equate to fly-away hair. Flying hair is due to the increased amount of static electricity and is generally manifested as an increase in the volume of only a very small amount of hair, which is undesirable. Hair fullness, as used herein, on the other hand, is associated with an overall increase in hair volume. Consumers with fine hair desire fullness while controlling unwanted flyaways.

From the foregoing it can be appreciated that there remains a need to provide hair conditioning compositions which provide volume to the hair without compromising conditioning benefits such as softness, moisturization and flyaway control.

None of the prior art provides all of the advantages and benefits of the present invention.

Summary of the invention

The present invention relates to a hair conditioning composition comprising, by weight:

(a) from about 0.1% to about 5% of a hydrophobically modified cationic cellulose having the general formula:

In the formula, ^R is an alkyl group with about 8-22 carbon atoms; n is an integer from 1 to about 4000; x is an integer from 0 or 1 to about 6; y is a cationic substitution level, which is 0.1-1.0; its molecular weight not more than approximately 1,000,000;

(b) from about 0.01% to about 20% of a conditioning agent; and

(c) an aqueous carrier,

wherein the hair conditioning composition is capable of increasing loose hair volume by a volume index of 20 or greater as measured by the Instron volumetric method.

These and other features, aspects and advantages of the present invention will become apparent to those skilled in the art from a reading of the present disclosure.

At the pH of the intended use, the charge density should be within the above limits.

Any anionic counterion can be used in the cationic polymer provided that the water solubility criteria are met. Suitable counterions include halides (eg Cl, Br, I or F, preferably Cl, Br or I), sulfate and methylsulfate. This example is not absolute, so other counterions may also be used.

The cationic nitrogen-containing moiety is usually present as a substituent on a portion of the total monomer units of the cationic hair conditioning polymer. Thus, the cationic polymer may comprise copolymers, terpolymers, etc. of quaternary ammonium or cationic amine substituted monomeric units and other non-cationic units (referred to herein as spacer monomeric units). These polymers are known in the art and can be found in the CTFA Cosmetic Ingredient Dictionary, Third Edition, Ed.

Other suitable spacer monomers include vinyl esters, vinyl alcohol (produced by hydrolysis of polyvinyl acetate), maleic anhydride, propylene glycol and ethylene glycol.

Depending on the particular species and pH of the composition, the cationic amines can be primary, secondary or tertiary. In general, secondary and tertiary amines are preferred, with tertiary amines being especially preferred.

Amine substituted vinyl monomers can be polymerized in the amine form and then optionally can be converted to ammonium by quaternization. Amines can also be similarly quaternized after polymer formation. For example, tertiary amine functional groups can be quaternized by reaction with salts of the general formula R'X, where R' is a short chain alkyl group, preferably C ₁ -C ₇ alkyl, more preferably C ₁ - _C3 alkyl, and X is an anion that forms a water-soluble salt with quaternized ammonium.

polysiloxane compound

The silicone compound may be included in the composition, preferably at a level by weight of from about 0.1% to 10%, more preferably from about 0.25% to 8%, most preferably from about 0.5% to 3%.

The silicone compounds of the present invention may include volatile soluble or insoluble, or nonvolatile soluble or insoluble silicone conditioning agents. Soluble means that the silicone compound is miscible with the carrier of the composition to form part of the same phase. Insoluble means that the polysiloxane forms a separate, discontinuous phase from the carrier, for example in the form of an emulsion or suspension of polysiloxane droplets. The polysiloxane compound in the present invention can be prepared by conventional polymerization or emulsion polymerization.

Silicone compounds suitable for use herein preferably have a viscosity of from about 1,000 to 2,000,000 centistokes at 25°C, more preferably from about 10,000 to 1,800,000 centistokes, most preferably from about 25,000 to 1.500,000 centistokes. The viscosity can be measured by a glass capillary viscometer as described in Dow Corning Corporate Test Method CTM0004, July 20, 1970, which is incorporated herein by reference in its entirety. High molecular weight polysiloxane compounds can be prepared by emulsion polymerization.

Silicone compounds suitable for use herein include polyalkylpolyarylsiloxanes, polyalkylene oxide-modified silicones, silicone resins, amino-substituted silicones, and mixtures thereof . The polysiloxane compound is preferably selected from polyalkyl polyaryl siloxanes, polyalkylene oxide-modified siloxanes, polysiloxane resins and mixtures thereof, more preferably from one or more A polyalkylpolyarylsiloxane.

Polyalkylpolyarylsiloxanes suitable for use in the present invention include those materials having the following structure (I):

In the formula, R is an alkyl or aryl group, and x is an integer of about 7-8,000. "A" denotes a group blocking the end of the polysiloxane chain. The alkyl or aryl group (R) substituted on the siloxane chain or the alkyl or aryl group (A) substituted on the end of the siloxane chain may have any structure as long as the polysiloxane obtained is at room temperature Remains fluid, is dispersible, is non-irritating, non-toxic, non-hazardous when applied to the hair, is compatible with other ingredients in the composition, is chemically stable under normal conditions of use and storage Stable and able to deposit on and condition hair. Suitable A groups include hydroxy, methyl, methoxy, ethoxy, propoxy and aryloxy. The two R groups on the silicon atom may represent the same or different groups. Preferably, the two R groups represent the same group. Suitable R groups include methyl, ethyl, propyl, phenyl, methylphenyl and phenylmethyl. Preferred silicone compounds are polydimethylsiloxane, polydiethylsiloxane and polymethylphenylsiloxane. Polydimethylsiloxane, also known as dimethicone, is especially preferred. Polyalkylsiloxanes that may be used include, for example, polydimethylsiloxanes. These silicone compounds are commercially available, for example, from the General Electric Company in their ViscasilR and SF 96 series and from Dow Corning in their Dow Corning 200 series. For example, polymethylphenylsiloxanes from the General Electric Company as SF 1075 methylphenyl fluid or from Dow Corning as 556 Cosmetic Grade Fluid are suitable for use in the present invention.

Also preferred for enhancing the shine properties of hair are highly arylated polysiloxane compounds having a refractive index of about 1.46 or higher, especially about 1.52 or higher, such as highly phenylated polyethylsiloxane oxane. When these high-refractive-index silicone compounds are used, they should be mixed with a spreading agent such as a surfactant or a silicone resin as described below in order to lower the surface tension of the substance and improve its film-forming ability.

Another particularly suitable polyalkylsiloxane is silicone gum. As used herein, the term "silicone gum" refers to a polyorganosiloxane having a viscosity at 25°C of greater than or equal to 1,000,000 centistokes. It should be recognized that the silicone gums described herein may also have some overlap with the silicone compounds described above. This overlap is not a limitation to any of these substances. Silicone gums are described by Petrarch, and others include U.S. Patent 4,152,416 (Spitzer et al., issued May 1, 1979) and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Also describing silicone gums are General Electric SiliconeRubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. All of these documents are incorporated herein by reference in their entirety. The "silicone gums" generally have a molecular weight above about 200,000, usually in the range of about 200,000-1,000,000. Examples include polydimethylsiloxane, poly(dimethylsiloxane methylvinylsiloxane) copolymer, poly(dimethylsiloxane diphenylsiloxane methylvinylsiloxane) ) copolymers and mixtures thereof.

Polyalkylene oxide-modified siloxanes suitable for use in the present invention include, for example, polyoxypropylene-modified and polyoxyethylene-modified polydimethylsiloxanes. The levels of ethylene oxide and propylene oxide should be low enough not to affect the dispersion properties of the polysiloxane. These substances are also known as dimethicone copolyols.

Silicone resins which are highly crosslinked polysiloxane systems are also suitable for use in the present invention. The crosslinking is introduced by incorporation of trifunctional and tetrafunctional silanes together with monofunctional or difunctional silanes or both during the production of the polysiloxane resin. As is known in the art, the degree of crosslinking required to obtain a silicone resin will vary depending on the particular silane units incorporated into the silicone resin. In general, polysiloxane materials having sufficient levels of trifunctional and tetrafunctional silane monomer units, and therefore crosslinking, such that they form hard or strong films when dry, can be considered Polysiloxane resin. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials having a ratio of oxygen atoms to silicon atoms of at least about 1.1 are typically silicone resins of the present invention. Preferably, the ratio of oxygen atoms to silicon atoms is at least about 1.2:1.0. Silanes used in the preparation of polysiloxane resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl- and methylethylene chlorosilanes and tetrachlorosilanes, of which methyl-substituted silanes are the most commonly used. Preferred resins are offered by General Electric as GE SS4230 and SS4267. Commercially available silicone resins are generally supplied dissolved in low viscosity volatile or nonvolatile silicone fluids. It will be apparent to those skilled in the art that the silicone resins useful herein should be provided in such dissolved form and incorporated into the compositions of the present invention. Without being bound by theory, it is believed that the silicone resins enhance the deposition of other silicone compounds on the hair and can enhance the shine of hair having high refractive index volume.

Other silicone resins that may be used are silicone resin powders, such as the material with the CTFA designation polymethylsilsesquioxane, commercially available as Tospearl ^(TM) from Toshiba Silicones.

Silicone resins are relatively conveniently identified according to a shorthand nomenclature system ("MDTQ" nomenclature) known to those skilled in the art. Under this nomenclature, polysiloxanes are described in terms of the presence of the various siloxane monomer units that make up the polysiloxane. In short, the symbol M represents the monofunctional unit (CH ₃ ) ₃ SiO) ₅ ; D represents the difunctional unit (CH ₃ ) ₂ SiO; T represents the trifunctional unit (CH ₃ ) SiO _1.5 ; Q represents the tetrafunctional unit SiO ₂ . Primed unit symbols such as M', D', T' and Q' represent substituents other than methyl and must be specifically defined for each case. Typical alternative substituents include groups such as vinyl, phenyl, amino, hydroxy, and the like. Under the MDTQ system, the polysiloxane material is completed with a symbolic subscript indicating the total number of various units in the polysiloxane or its average value, or as a specifically indicated ratio combined with the molar ratio of the different units represented by the molecular weight description of. A higher relative molar amount of T, Q, T' and/or Q' relative to D, D', M and/or M' in a polysiloxane resin means a higher level of crosslinking. However, as noted above, the overall level of crosslinking can also be expressed by the ratio of oxygen to silicon.

Preferred polysiloxane resins useful herein are the MQ, MT, MTQ, MDQ and MDTQ resins. Accordingly, the preferred polysiloxane substituent is methyl. Especially preferred are MQ resins wherein the M:Q ratio is from about 0.5:1.0 to about 1.5:1.0 and the resin has an average molecular weight from about 1000 to about 10,000.

Other amino-substituted siloxanes that can be used are represented by the general formula (V):

In the formula, R ³ represents a monovalent hydrocarbon group with 1-18 carbon atoms, preferably an alkyl or alkenyl group, such as methyl; R ₄ represents a hydrocarbon group, preferably a C ₁ -C ₁₈ alkylene group or a C ₁ -C ₁₈ , more preferably C ₁ -C ₈ alkylene oxide; Q ^- is a halide ion, preferably chlorine; r represents the average statistical value of 2-20, preferably 2-8; s represents the average statistical value of 20-200, Preferably 20-50.

The emulsifier may be a cationic surfactant contained in a cationic silicone emulsion, or other suitable surfactant. Mechanical emulsification may require the use of two or more surfactants and the mixing of two or more different surfactants. Two or more kinds of silicone compounds, such as a highly viscous silicone compound and a low viscosity silicone compound, may be used. A particularly preferred method for obtaining the cationic silicone emulsions of the present invention by mechanical emulsification is the method described in European publication 460,683A, which is hereby incorporated by reference in its entirety. This reference discloses that the emulsion is prepared by mixing polysiloxane, water and a primary nonionic surfactant having an HLB value of 15-19 to form a first mixture, to which is added a nonionic , cationic and anionic surfactants having an HLB value of 1.8-15 co-surfactants to form a second mixture, and mixing the second mixture at a temperature of about 40°C until particles of polysiloxane in the emulsion The size is below about 300nm.

INSTRON volumetric method

The Instron volumetric method is used to analyze the loose hair volume of a hair sample by volume index, which is calculated from the tensile work when the hair sample is stretched and passed through an annular hole. The tension work is proportional to the loose hair volume, and proportionally more tension work should be required to increase the volume of the loose hair when a hair sample is stretched and passed through an annular hole of constant diameter.

The hair conditioning compositions of the present invention provide a noticeable, dramatic increase in loose hair volume. This increase in loose hair volume can be assessed by a Volume Index, and the hair conditioning compositions of the present invention have a Volume Index of 20 or higher, preferably 25 or higher, more preferably 30 or higher, as determined as follows described in the text.

As used herein, the term "increase in loose hair volume" does not equate to flyaway hair. Flying hair is due to an increase in the amount of static electricity and appears as an increase in the volume of only a very small amount of hair in the entirety of the hair, which is undesirable. On the other hand, as used herein, loose hair volume increase is associated with an overall increase in hair volume while controlling flyaways.

Referring to the drawings, Figure 1 is a side view of a preferred embodiment of an Instron volumetric apparatus useful in the present invention. The Instron volumetric apparatus consists of a small Instron Tensometer MN 55 with Merlin Profiler software (hereinafter Tensometer, obtained from Instron Computer), 1 and Station 6. The tensile tester 1 includes an Instron load cell 2 , a wire 3 and a sample holder 4 . The sample holder 4 is typically a clip or clamp that can hang the hair sample 7 stably. The table 6 has an annular hole 5 in its center.

The tensile tester measures the tensile strength when a hair sample 7 is passed through an annular hole 5 by stretching it with an Instron manometer 2 with a wire 3 and a sample holder 4 .

The table 6 has a suitable height so that the hair sample 7 does not touch its bottom when placed on the sample holder 4 . The annular hole 5 has a suitable diameter for determining the tensile strength, for example in this embodiment the diameter of the annular hole of the table is 35mm.

Preferably, the device should be kept away from drafts or other forces that could disturb the hair sample, and should be in a controlled temperature and humidity environment to ensure reproducible results.

The hair sample 7 typically consists of 20 cm (8 grams) of straight brown Caucasian hair switches (hair switches) (obtained from International Hair Importers & products Inc., Bellerose, New York, USA). However, the hair volume increasing benefits of the present invention are applicable to all types of hair samples. Furthermore, it has been found that the results obtained with hair samples are comparable to those obtained during actual use in humans.

Hair sample 7 was prepared as follows:

For the initial hair sample

1) Wet the hair sample with 0 g of water, then apply 12% ammonium lauryl sulfate solution (0.1 g/1 g hair) to the hair sample to remove hair soil.

2) Lather for 30 seconds and rinse for 30 seconds (the same washing conditions should be used, including water temperature, water flow rate and water hardness).

3) Apply a 12% ammonium lauryl sulfate solution (0.1 g/1 g hair) to the hair swatch.

4) Lather for 30 seconds and rinse hair swatch for 60 seconds.

5) Comb wet hair swatch thoroughly to remove tangles.

6) Squeeze excess water from the hair swatch and bring the hair swatch into a flat square shape.

7) Place the hair swatch in a 25°C/50% relative humidity room and dry for 24 hours.

For treated hair samples

1) The hair sample obtained above was moistened with 0 g of water, and then 0.1 ml of the sample shampoo was applied per 1 g of hair.

2) Lather for 30 seconds and rinse for 30 seconds.

3) Apply 0.1 ml of sample shampoo per 1 gram of hair.

4) Lather for 30 seconds and rinse for 60 seconds.

5) For conditioning, apply 0.1 ml of sample conditioner per 1 gram of hair for 30 seconds, comb for 15 seconds and rinse for 30 seconds.

6) Squeeze excess water from the hair swatch and bring the hair swatch into a flat square shape.

7) Place the hair swatch in a 25°C/50% relative humidity room and dry for 24 hours.

The sample shampoo used here was Prell shampoo (a non-conditioning shampoo currently marketed in the US) or the shampoo composition referred to as "Shampoo 1" in the examples. The sample conditioner mentioned here is one of the conditioning compositions in the "Conditioner 1" - "Conditioner 7" mentioned in the examples.

Typically, the same hair swatch is first tested as the "raw hair sample" and then as the "treated hair swatch", both raw and treated hair samples being prepared according to the methods described above.

Once the hair swatch (raw or treated) is prepared, the hair swatch is combed through 7 times and then secured in the sample holder 4 through the annular hole 5 of the table 6 . During each measurement, the distance between the sample holder 4 and the annular hole 5 should be the same.

Then the Instron pressure gauge 2 moves upwards to a suitable height from the bottom, and the hair sample 7 is stretched by the Instron pressure gauge 2 through the wire 3 and the sample clamp 4 (stretching speed: 4mm/sec). The hair sample passes through the annular hole 5 when the hair sample is stretched. Tensile strength was determined using the Merlin Profiler software as the hair sample passed through the annular hole 5.

The assay is repeated 3 times for one hair swatch (original or treated) and 3 hair swatches are treated identically with the same shampoo and/or the same conditioner. Thus, for the same treatment, a total of 9 measurements were made on the treated hair sample and a total of 9 measurements were made on the original hair sample.

The tensile strength data is transferred to a computer to calculate the work of tension at some suitable distance, preferably the first 8 cm of the hair sample. Calculated using the following equation:

x＝D

Tension work (mJ) = ∫Fdx

x=0

where F is the extension load of the Instron manometer when the hair sample is stretched through the annular hole at a distance x; D is the length of the hair sample used for the measurement.

The difference between the tension work of the treated and original hair samples was then calculated. This calculation is performed using the following equation.

Δ = work _processed - work _initial

The difference was calculated for each of the 9 measurements for the same treatment and then combined to obtain the mean value of the tension work ( _Δtreatment ) for each of the same treatments.

The _above actual tension work data _{( Δtreatment} ) into volume index. The upper volume control treatment was the treatment described as "Treatment 1" in the Examples below using Prell shampoo without any conditioning agent (a non-conditioning shampoo currently marketed in the US). The lower limit volume control treatment is a treatment employing the shampoo and conditioner described in the Examples below as "Shampoo 1" and "Conditioner 1", and in the Examples as "Treatment 2". The conversion is performed using the following equation:

Preparation

The shampoo composition of "Shampoo 1" mentioned above can be prepared by conventional methods known in the art. Suitable methods are described below.

The polymer and surfactant are dispersed in water to form a homogeneous mixture. To this mixture are added the other ingredients except spices and salt; the obtained mixture is stirred. The resulting mixture is then passed through a heat exchanger for cooling before adding spices and salt. The obtained composition was poured into bottles to form a hair shampoo composition. In addition, water can be mixed with surfactants and other solids that need to be melted at higher temperatures, such as over 70°C, to speed up the mixing into shampoos. Other ingredients can be added to the hot premix or after cooling the premix. The ingredients are thoroughly mixed at elevated temperature and then pumped through a high shear mill followed by a heat exchanger to cool it down to ambient temperature. The cationic silicone emulsion was then added to the cooled mixture at room temperature and stirred thoroughly.

The hair conditioning compositions of "Conditioner 1" to "Conditioner 7" mentioned above can be prepared by any conventional method known in the art. They may be prepared in a suitable manner by dispersing the polymeric material, such as hydrophobically modified cationic cellulose and polyethylene glycol, in water at room temperature, if the composition comprises a polymeric material, to form a polymer solution and heated above 70°C. To this solution is added the amidoamine and acid or other cationic conditioning agent and low melting point ester oil, if present, with stirring. The high melting point fatty compound and other low melting point oils (if present) and benzyl alcohol are then added to this solution with stirring. The mixture thus obtained is cooled to below 60°C and the remaining ingredients, such as cationic silicone emulsion (if present) are added thereto while stirring and further cooled to about 30°C.

If desired, a triblender and/or mill may be used at each step to disperse the material.

The embodiments disclosed and represented by "Conditioner 2" through "Conditioner 7" above have a number of advantages. For example, they increase loose hair volume, softness, moisturization and flyaway control.

It should be understood that the examples and specific implementations described in the present invention are only illustrative, and those skilled in the art may make various changes or changes thereto without departing from the spirit and scope of the present invention.
