Description

Hair conditioning composition comprising particles

technical field

The present invention relates to hair conditioning compositions comprising particles.

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

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

While some consumers prefer the ease and convenience of shampoos containing conditioning agents, a significant percentage prefer more conventional conditioning formulations. These formulations are applied to the hair independently of shampooing, usually after shampooing. Conditioning products can be rinse-off or leave-on products, and can be lotions, creams, gels, sprays and mousses. Such consumers, who prefer conventional conditioner products, value higher conditioning benefits, or the convenience of varying the amount of conditioning depending on the condition of the hair or the size of the hair.

There is a need for a hair conditioning composition which, when spread on hands and/or hair, provides improved texture. However, conventional hair conditioning products are not fully satisfied to produce improved structure and provide improved conditioning benefits to hair, such as moisturized feel, softness and static control, while having suitable viscosity.

Based on the foregoing, there remains a need to provide a hair conditioning composition which when spread on the hands and/or the hair produces improved texture, is easier to apply to the hair and provides improved conditioning Effects such as hair moisturization, softness and static control.

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

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

A silicone compound may also be included in Composition B, preferably at a level by weight of from about 0.1% to about 10%, more preferably from about 0.25% to about 8%, most preferably from about 0.5% to about 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 at 25°C of from about 1,000 to about 2,000,000 centistokes, more preferably from about 10,000 to about 1,800,000, even more preferably from about 25,000 to about 1,500,000. The viscosity can be measured by the glass capillary viscometer method 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 Polyalkylpolyarylsiloxane.

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

wherein R is an alkyl or aryl group, and x is an integer from about 7 to about 8,000. "A" represents 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 hair, is compatible with other ingredients in the composition, and is chemically stable under normal conditions of use and storage , and can be deposited on the hair and condition the 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. Polydimethylsiloxanes, also known as simethicones, are 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 Viscasil® 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.

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 benzolated polyethylpolysiloxane alkyl. When these high-refractive-index silicone compounds are used, they should be mixed with a coating agent such as a surfactant or a silicone resin as described below in order to lower the surface tension and improve its film-forming ability.

Another polyalkylpolyarylsiloxane which is particularly suitable is silicone gum. 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, including U.S. Patent No. 4,152,416 to Spitzer et al., published May 1, 1979, and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Others describing silicone gums are General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. All such described documents are hereby incorporated by reference in their entirety. The mass molecular weight of "polysiloxane gum" is generally above about 200,000, usually between 200,000 and about 1,000,000. Specific examples include polydimethylsiloxane, poly(dimethylsiloxane methylvinylsiloxane) copolymer, poly(dimethylsiloxane-diphenylsiloxane-methylvinylsiloxane) base siloxane) 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 ethylene oxide and propylene oxide levels should be low enough not to affect the dispersibility of the polysiloxane. These materials are also known as dimethicone copolyols.

Polysiloxane resins of highly crosslinked polymeric siloxane 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 moieties incorporated into the silicone resin. In general, polysiloxane materials having a sufficient content of trifunctional and tetrafunctional silane monomer units, and thus a sufficient level of crosslinking, such that they form rigid 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 of a particular silicone material. Silicone materials having at least about 1.1 oxygen atoms per silicon atom are typically silicone resins of the present invention. Preferably, the ratio of oxygen to silicon atoms is at least about 1.2:1.0. Silanes used in the manufacture of polysiloxane resins include monomethyl-, dimethyl-, trimethyl-, phenyl-, biphenyl-, methylphenyl-, vinyl- and methylvinyl chloride Methyl silanes and tetrachlorosilanes, of which methyl substituted silanes are the most commonly used. Preferred resins are GESS4230 and SS4267 supplied by General Electric. Commercially available silicone resins are generally supplied in dissolved form in low viscosity volatile or nonvolatile silicone liquids. 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 enhance the shine of hair with high refractive index volume.

Other silicone resins that can be used are silicone resin powders such as the material with the CTFA designation polymethylsilsequoxane, which is commercially available as Tospearl ^(R) from Toshiba Silicones.

Silicone resins are more conveniently identified according to an abbreviated nomenclature ("MDTQ" nomenclature) known to those skilled in the art. Under this nomenclature, silicones are described in terms of the presence of the various siloxane monomers that make up the silicones. Briefly, the symbol M represents a monofunctional unit (CH ₃ ) ₃ SiO) _.5 ; D represents a difunctional unit (CH ₃ ) ₂ SiO; T represents a trifunctional unit (CH ₃ ) SiO _1.5 ; Q represents a tetrafunctional unit SiO ₂ . Major parts in the unit symbols, such as M', D', T' and Q' represent substituents other than methyl and are defined specifically for each case. Typical other substituents include groups such as vinyl, phenyl, amino, hydroxyl, and the like. Under the MDTQ system, polysiloxanes are completed in terms of symbolic subscripts denoting the total number of the various units in the polysiloxane, or in terms of their average value, or as molar ratios of the different units in specific indicated proportions expressed together with the molecular weight. A description of the alkane material. A higher 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 MQ, MT, MTQ, MQ 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 of from about 1000 to about 10,000.

Suitable amino-substituted silicone fluids include those compounds represented by the general formula (III):

(R ₁ ) _a G _3-a -Si-(-OSiG ₂ ) _n -(-OSiG _b (R ₁ ) _2-b ) _m -O-SiG _3-a (R ₁ ) _a (III)

In the formula, R ₂ is selected from hydrogen, phenyl, benzyl, saturated hydrocarbon group, preferably an alkyl group containing 1 to 20 carbon atoms, and A ^- represents a halogen atom.

Particularly preferred amino-substituted polysiloxanes corresponding to the general formula (III) are the polymeric polysiloxanes of the general formula (IV) known as "trimethylsilylaminodimethylpolysiloxane" thing:

In this general formula, n and m are selected according to the desired molecular weight of the compound.

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 to 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.

polypropylene glycol

Composition A according to the invention preferably also contains polypropylene glycol. Polypropylene glycol may be included in Composition A at a level of from about 0.1% to about 10%, more preferably from about 0.25% to about 6%, by weight.

Polypropylene glycol may also be included in Composition B at a level of from about 0.1% to about 10%, more preferably from about 0.25% to about 6%, by weight.

Polypropylene glycols suitable for use herein generally have a weight average molecular weight of from about 200 to about 100,000 grams/mole, preferably from about 1,000 to about 60,000 grams/mole. Without being bound by theory, it is believed that the polypropylene glycols of the present invention deposit on or adsorb to the hair to act as moisturizers, and/or to provide one or more other desirable hair conditioning benefits. The term "polypropylene glycol" as used herein includes both mono-polypropylene glycol-segmented polymers and multi-polypropylene glycol-segmented polymers. For example, in "Principles of Polymerization" pp. 17-19, GOdian, (John Wiley & Sons, Inc., 3 ^rd ed., 1991) describes the development of branched polymers, such as polypropylene glycol-segmented polymers. general structure.

The polypropylene glycols useful herein have a polydispersity of from about 1 to about 2.5, preferably from about 1 to about 2, more preferably from about 1 to about 1.5. As used herein, the term "polydispersity" refers to the degree of molecular weight distribution of a polymer sample. In particular, polydispersity is a ratio greater than 1 equal to weight average molecular weight divided by number average molecular weight. For further discussion of polydispersity see "Principles of Polymerization", pp. 20-24, G. Odian, (John Wiley & Sons, Inc., 3 ^rd ed., 1991).

Depending on the degree of polymerization and whether other groups are attached, the polypropylene glycols useful in the present invention can be water soluble, water insoluble, or have limited solubility in water. The desired solubility of polypropylene glycol in water depends largely on the type of hair care composition (eg, leave-on or rinse-off). The solubility of the polypropylene glycol used in the present invention in water can be selected by those skilled in the art based on various factors. Thus, for leave-on hair care compositions, the polypropylene glycol is preferably a water-soluble polypropylene glycol. Solubility information is readily available from suppliers of polypropylene glycols such as Sanyo Kasei (Osaka, Japan). However, the invention may also be in the form of a rinse-off hair care composition. Without being bound by theory, it is believed that in such compositions the water soluble polypropylene glycol may be very easily washed off before it is effectively deposited on the hair and provides the desired benefit. For such compositions therefore poorly water soluble or even water insoluble polypropylene glycols are preferred. So for rinse-off hair care compositions, the solubility of polypropylene glycol in water at 25° C. is less than about 1 g/100 g water, more preferably less than about 0.5 g/100 g water, even more preferably less than about 0.1 g/100 g water. 100 grams of water.

Preparation

The hair conditioning compositions as described in Examples 1 and 9 are prepared by any conventional method known in the art. They are suitably prepared in the following manner: If a polymeric material is included in the composition, the polymeric material, such as polypropylene glycol, is dispersed in water at room temperature to form a polymer solution and this is heated up to 70°C. To this solution is added the amidoamine and the acid or other cationic surfactant (if present) and the ester oil of the low melting point oil with stirring. The high melting point fatty compound is then added to this solution with stirring, along with other low melting point oils and benzyl alcohol (if present). The mixture thus obtained is cooled to below 60°C, and the remaining ingredients, such as silicone compounds, are added thereto with stirring and further cooled to about 30°C. Then, particles such as silica and mica are added and mixed.

Three-roll mills and/or ball mills can be used at each step to disperse the raw materials, if desired.

It is also possible to add up to 50% acid after cooling to below 60°C.

Embodiments disclosed herein have many advantages. For example, they provide improved texture when spread on the hands and/or hair and provide improved conditioning benefits to the hair, such as moisturized feel, softness, and static control, and are easy to apply to the hair.

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.
