Description

hair care composition

The present invention relates to hair care compositions. In particular, the present invention relates to hair care compositions that spread easily throughout the hair and provide improved conditioning and shine while reducing stickiness and greasy feel.

Background of the invention

Hair is constantly subject to various aggressions that can cause damage. These include shampooing, rinsing, drying, heating, combing, styling, perming, coloring, exposure to various environments. As a result the hair is often left in a dry, rough, dull or frizzy state due to friction between the surfaces and removal of the hair's natural oils and other natural conditioning and moisturizing ingredients.

To alleviate these problems, various means have been taken. These include the use of ultra-mild shampoo compositions, the use of conditioning shampoos which attempt to cleanse and condition the hair simultaneously with one product, and the use of hair conditioning formulations such as rinse-off and leave-on products.

Leave-on hair care formulations offer additional advantages over other approaches. For example, leave-on formulations are more economical and work for a longer period of time because the conditioning ingredients are left on the hair. They are more convenient because the consumer can use them at any time without having to wait to rinse the product off. Plus, this product can be applied to those sections of hair that need conditioning the most.

Typically, conditioning benefits are provided through the use of hair conditioning agents such as cationic surfactants, cationic polymers, silicone conditioning agents, hydrocarbons and other organic oils and solid fatty materials such as fatty alcohols. These conditioning agents are well known in the art. See, for example, WO-A-97/35542, WO-A-97/35545, WO-A-97/35546, all of which describe the use of conditioning agents in shampoo compositions.

Ideally, these conditioning agents are deposited on the hair fiber, leaving the hair feeling smooth and looking shiny. Preferably, the composition should work readily throughout the hair to ensure very even deposition of the conditioning agent along the hair shaft. However, conditioning compositions, especially leave-on compositions that do not use a rinse step, are often difficult to spread and deposit too much conditioning agent in an uneven manner. In this way, the hair becomes progressively soiled, coated, leaving the hair looking lifeless and unstyled. The above problems are particularly noticeable when the composition is used repeatedly and the hair is not shampooed every day. Therefore, it is desirable to formulate easily to work throughout the hair and deposit the conditioning agent in an even manner. It is also desirable that these compositions provide a refreshment to the consumer's scalp.

Recently, silicone resins have been proposed as hair conditioning agents. For example, GB-A-2297757 describes low viscosity organofunctional siloxysilicates and gives examples of their use in hair care compositions, the above patent application being incorporated herein by reference. However, this document does not address the need to provide hair care compositions that impart shine and conditioning benefits and are easy to work through the hair without leaving the hair feeling overly sticky or greasy.

Surprisingly, it has now been found that by combining a polysiloxane resin in which at least one substituent of the resin has delocalized electrons and a _C1 - _C6 aliphatic alcohol provides ease of dispersion and delivers good conditioning and gloss benefits A hair care composition that simultaneously reduces stickiness and greasiness. Additionally, the compositions of the present invention leave the scalp feeling refreshed without leaving the hair feeling dry.

Summary of the invention

The present invention provides a hair care composition comprising:

(a) polysiloxane resins, wherein at least one substituent in the resin has delocalized electrons; and

(b) C ₁ -C ₆ aliphatic alcohols.

The compositions of the present invention spread easily throughout the hair and provide good conditioning and shine benefits while reducing stickiness and greasiness. In addition, the compositions of the present invention provide a refreshing feel to the scalp.

All concentrations and ratios herein are by weight of the hair care composition unless otherwise specified.

All averages herein are weight averages unless otherwise indicated.

Detailed description of the invention

The hair care composition of the present invention comprises two main ingredients, polysiloxane resin and C1-C6 aliphatic alcohol, wherein at least one substituent in the resin possesses delocalized electrons. These components will be described in detail hereinafter.

The terms "sticky" and "sticky" as used herein refer to the sticky/tacky feel of the hair after application of certain hair care compositions.

The term "leave-on" as used herein refers to hair care compositions which are not intended to be subjected to a rinsing step. Thus, leave-on compositions will generally be left on the hair until the next time the consumer washes the hair as part of a cleansing regimen according to their cleansing habits. Leave-on formulations will generally preferably contain less than about 5% anionic surfactants and will generally contain less than 5% nonionic surfactants.

polysiloxane resin

An essential feature of the composition of the invention is that it comprises a polysiloxane resin in which at least one substituent of the resin has delocalized electrons. Hair care compositions of the present invention will comprise from about 0.001% to about 5%, preferably from about 0.005% to about 3%, more preferably from about 0.01% to about 2%, still more preferably from about 0.1% to about 1%, by weight poly Silicone resin.

Silicone resins are highly cross-linked polymeric siloxane systems. The crosslinking is introduced by mixing trifunctional and tetrafunctional silanes into monofunctional or difunctional or monofunctional and difunctional silanes during the production of polysiloxane resins. As is known in the art, the degree of crosslinking required to form a silicone resin can vary depending on the particular silane units incorporated into the silicone resin. In general, silicone materials that have enough trifunctional and tetrafunctional siloxane monomer units (and thus are sufficiently crosslinked) that they dry to rigid or hard films are considered silicone resins. 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 will generally be the 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 production of polysiloxane resins include monomethyl, dimethyl, trimethyl, monophenyl, diphenyl, methylphenyl, ethylphenyl, propylphenyl, monovinyl and Methylvinylchlorosilane and tetrachlorosilane.

The polysiloxane resin used in the present invention must have at least one substituent having delocalized electrons. The substituent may be selected from alkyl, aryl, alkoxy, alkaryl, arylalkyl, arylalkoxy, alkaryloxy, and combinations thereof. Preferred are aryl, arylalkyl and alkaryl substituents. More preferred are aralkyl and alkaryl substituents. Further preferred are alkaryl substituents, especially 2-phenylpropyl. Although at least one substituent must have delocalized electrons, the resins here often also have other substituents that do not have delocalized electrons. Such other substituents may include hydrogen, hydroxy, alkyl, alkoxy, amino functional groups and mixtures thereof. Preferred are alkyl substituents, especially methyl substituents. Particularly preferred for use in the present invention is therefore dimethyl(2-phenylpropyl)silyl ester.

The term "aryl" as used herein means a functional group containing one or more homocyclic or heterocyclic rings. The aryl functional groups herein may be unsubstituted or substituted and generally contain 3 to 16 carbon atoms. Preferred aryl groups include, but are not limited to, phenyl, naphthyl, cyclopentadienyl, anthracenyl, pyrene, pyridine, and pyrimidine.

The term "alkyl" as used herein means a saturated or unsaturated, substituted or unsubstituted, linear or branched hydrocarbon having 1 to 10 carbon atoms, preferably 1 to 4 carbon atoms. Thus, the term "alkyl" includes alkenyl groups having 2 to 8 carbon atoms, preferably 2 to 4 carbon atoms, and alkynyl groups having 2 to 8 carbon atoms, preferably 2 to 4 carbon atoms. Preferred alkyl groups include, but are not limited to, methyl, ethyl, propyl, isopropyl and butyl. More preferred are methyl, ethyl and propyl.

As used herein, the term "alkaryl" means a substituent comprising an alkyl moiety and an aryl moiety, wherein the alkyl moiety is attached to the silicone resin.

As used herein, the term "aralkyl" means a substituent comprising an aryl moiety and an alkyl moiety, wherein the aryl moiety is attached to the silicone resin.

Silicone materials, particularly silicone resins, are conveniently identified by the "MDTQ" nomenclature, a shorthand nomenclature system well known to those skilled in the art. In this system, 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 _0.5 ; 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 . Priming marks in unit symbols such as M', D', T', Q' represent siloxane units having one or more substituents other than methyl, which need to be specifically defined each time. Therefore, the polysiloxane resins used herein must have at least one M', D', T', O' functional group with one substituent having delocalized electrons. Preferred substituents are as defined above. Under the MDTQ system, the molar ratio of the various units is expressed either as a subscript indicating the total number (or average value) of each type of unit in the polysiloxane, or as a specifically indicated ratio combined with molecular weight, This completes the description of the polysiloxane species.

Preferred polysiloxane resins for _use in the present invention are _M'Q resins, more preferably _{M'6Q3 , M'8Q4} , _{M'10Q5 , M'12Q6} resins and mixtures thereof. Preferred M'Q resins are those having at least one delocalized electron-containing group substituted on each M' functional group. More preferred are those resins in which the other substituents are alkyl groups, especially methyl groups.
