Description

Hair conditioning composition comprising silicone polymers containing tetravalent groups

Technical Field

The present invention relates to a hair conditioning composition comprised of a silicone polymer comprising tetravalent groups and a gel matrix. The compositions of the present invention can provide improved conditioning benefits such as smooth feel and reduced friction to both damaged and undamaged hair, while providing other benefits such as slippery and slick feel on wet hair.

Background

Human hair becomes dirty due to contact with the surrounding environment and due to sebum secreted by the scalp. Soiling of the hair can cause it to have a dirty feel and to be unsightly. Soiled hair requires frequent cleaning.

Shampoos cleanse the hair by removing excess soil and sebum. However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state. After the hair dries, it is often in a dry, rough, lusterless or frizzy condition due to the removal of the hair's natural oils and other natural conditioning and moisturizing components. Furthermore, the hair may also be left with a relatively large amount of static electricity after it has dried, which not only hinders combing but also results in what is commonly referred to as "flyaway hair" or produces an undesirable phenomenon of "split ends", especially for long hair.

Various methods have been developed to condition hair. One common approach to providing conditioning benefits to hair is the use of hair conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point fats and oils, and silicone compounds. Most of these conditioning agents are known to provide conditioning benefits by deposition on the hair.

Human hair is damaged by, for example, shampooing, combing, perming, and/or coloring. Such damaged hair is often hydrophilic and/or in a rough condition, especially when the hair is in a dry condition, as compared to undamaged hair. There is a need for hair conditioning compositions that: which provides improved conditioning benefits such as smooth feel and reduced friction on dry hair, especially damaged hair.

Based on the foregoing, there remains a need for hair conditioning compositions that: which provides improved conditioning benefits such as smooth feel and reduced friction on dry hair, especially damaged hair. There is also a need for hair conditioning compositions: which provides the conditioning benefits described above, while providing other conditioning benefits such as slippery and slick feel on wet hair.

1. Cationic surfactant

The compositions of the present invention comprise a cationic surfactant. The cationic surfactant is a mono-long alkyl quaternary ammonium salt having the following formula (XIII):

wherein R is⁷¹、R⁷²、R⁷³And R⁷⁴One of which is selected from aliphatic groups of about 16 to about 30 carbon atoms or aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl groups having up to about 30 carbon atoms; other R⁷¹、R⁷²、R⁷³And R⁷⁴Independently selected from an aliphatic group of from about 1 to about 8 carbon atoms or an aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl group having up to about 8 carbon atoms; and X-is a salt-forming anion, e.g. selected from halogen, (e.g. salts of fluorine with fluorine)Such as chloride, bromide), acetate, citrate, lactate, glycolate, phosphate, nitrate, sulfonate, sulfate, alkyl sulfate, glutamate and alkyl sulfonate based. In addition to carbon and hydrogen atoms, aliphatic groups may also contain ether linkages and other groups such as amino groups. Longer chain aliphatic groups such as those having about 16 carbon atoms or more may be saturated or unsaturated. Preferably, R⁷¹、R⁷²、R⁷³And R⁷⁴One of which is selected from alkyl groups of about 16 to about 30 carbon atoms, more preferably about 18 to about 26 carbon atoms, still more preferably about 22 carbon atoms, and the others of which are R⁷¹、R⁷²、R⁷³And R⁷⁴Independently selected from the group consisting of: CH (CH)₃、C₂H₅、C₂H₄OH、CH₂C₆H₅And mixtures thereof; and (X) is selected from the group consisting of the following anions: cl, Br, CH₃OSO₃And mixtures thereof. It is believed that these monolong alkyl quaternized ammonium salts can provide improved wet hair smoothness and smoothness compared to the longest alkyl quaternized ammonium salts.

Among them, more preferred cationic surfactants are those having a longer alkyl group, i.e., C₂₂Those of alkyl groups. Such cationic surfactants include, for example, behenyltrimethylammonium chloride and behenyltrimethylammonium methylsulfate. It is believed that cationic surfactants with longer alkyl groups provide improved hair drying hydrophobicity compared to cationic surfactants with shorter alkyl groups. It is also believed that the long alkyl group containing cationic surfactants can provide improved hydrophobicity to hair, especially damaged hair, when combined with the esters of polyhydroxy compounds of the present invention, as compared to shorter alkyl group containing cationic surfactants. Alternatively, it is believed that cationic surfactants containing sufficiently long alkyl groups provide improved wet hair smoothness and smoothness compared to cationic surfactants containing too long alkyl groups. Thus, it is believed that C is selected in the long alkyl group₂₂The alkyl groups provide a balance of benefits between improved dry hair hydrophobicity and improved wet hair smoothness and smoothness.

When these high refractive index silicone compounds are used, they should be mixed with a spreading agent (such as a surfactant or silicone resin described below) to reduce surface tension and enhance the film-forming ability of the material.

Another polyalkyl polyaryl siloxane that is particularly useful is a silicone gum. The term "silicone gum" as used herein means having a thickness of greater than or equal to 1m at 25 ℃²Polyorganosiloxane material of viscosity/s (1,000,000 centistokes). It should be recognized that the silicone gums described herein may also have some repetition with the silicone compounds disclosed above. This repetition is not intended to be limiting with respect to any of these materials. Silicone gums are described by Petrarch, among others, including U.S. Pat. No. 4,152,416 issued to Spitzer et al on 5/1 1979 and "Chemistry and Technology of Silicones" by Noll, Walter (New York: Academic Press 1968). Also described for the Silicone gums are "General Electric Silicone Rubber products" SE30, SE33, SE54 and SE 76. All of these documents are incorporated by reference herein in their entirety. "Silicone gums" typically have a weight average molecular weight in excess of about 200,000, generally between about 200,000 and about 1,000,000. Specific examples include polydimethylsiloxane, poly (dimethylsiloxane methylvinylsiloxane) copolymers, poly (dimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymers, and mixtures thereof.

Polyalkylene oxide-modified silicones useful in the invention include, for example, polypropylene oxide-modified and polyethylene oxide-modified polydimethylsiloxanes. These materials are also known as dimethicone copolyols.

Silicone resins, which are highly crosslinked polysiloxane systems, are useful herein. The crosslinking is introduced by mixing trifunctional and tetrafunctional silanes with monofunctional or difunctional silane silanes or both during the production of the silicone resin. As is well understood 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. Generally, silicone materials having sufficient trifunctional and tetrafunctional siloxane monomer units to have a sufficient degree of crosslinking such that they can form a rigid or hard film upon drying are considered to be silicone resins. The ratio of oxygen atoms to silicon atoms is an indication of the level of crosslinking of a particular silicone material. The silicone resins of the present invention are generally silicone materials having at least about 1.1 oxygen atoms per silicon atom. Preferably, the ratio of oxygen to silicon atoms is at least about 1.2: 1.0. Silanes used in the preparation of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, and methylvinylchlorosilanes, and tetrachlorosilane, with methyl-substituted silanes being most commonly used. Preferred resins may be supplied by GE Advanced Materials as GE SS4230 and SS 4267. Commercially available silicone resins are typically provided in a form dissolved in a low viscosity volatile or nonvolatile silicone liquid. It will be apparent to those skilled in the art that silicone resins suitable for use in the present invention should be provided and incorporated in such dissolved form in the compositions of the present invention. Without being bound by theory, it is believed that the silicone resin may enhance deposition of other silicone compounds on the hair and may enhance the shine of the hair, giving it a high refractive index volume.

Other silicone resins that can be used are silicone resin powders, such as the CTFA name polymethylsilsesquioxane, marketed by GE Toshiba Silicones as Tospearl^TM。

Silicone resins are more conveniently identified according to the shorthand nomenclature system ("MDTQ" nomenclature) well known to those of ordinary skill in the art. Under this system, the siloxane is described in terms of the various siloxane monomer units present that make up the siloxane. Briefly, the symbol M represents a functional unit (CH)₃)₃SiO_0.5(ii) a D represents a difunctional unit (CH)₃)₂SiO; t represents a trifunctional unit (CH)₃)SiO_1.5(ii) a And Q represents a quaternary or tetra-functional unit SiO₂. The main moieties in the unit symbols such as M ', D', T 'and Q' represent substituents other than methyl, and are specifically defined for each case. Typical other substituents include groups such as vinyl, benzeneRadicals, amino radicals, hydroxyl radicals and the like. The molar ratios of the units, either in the total number of units of each type in the siloxane or an average thereof, as subscripted by the symbol, or in the ratios specifically indicated in combination with molecular weight, allow for the description of the siloxane material in terms of the MDTQ system. In silicone resins, a higher molar amount of T, Q, T 'and/or Q' relative to D, D ', M and/or M' means a higher degree of crosslinking. However, as mentioned above, the overall degree of crosslinking can also be expressed in terms of the ratio of oxygen to silicon.

Silicone resins useful herein are preferably MQ, MT, MTQ, MQ and MDTQ resins. Thus, the preferred siloxane 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, the resins having an average molecular weight of from about 1000 to about 10,000.

Elasticity and viscosity

It has been found that the silicone blends useful in the present invention have preferred tan delta values. Tan δ is a calculation related to the elasticity of the blend material and is equal to the loss modulus (G ") divided by the storage modulus (G'). The loss modulus (G ") and the storage modulus (G') were measured by the following methods:

the instrument comprises the following steps: TA AR2000 or AR-G2 rheometer, using a 40mm diameter 2 degree AL cone with a gap of 57 μm oscillation mode.

Sample preparation: the sample was hollowed out with a spatula and placed on the measurement bench of the rheometer without stirring to avoid the generation of air bubbles.

Measurement procedure: 1) equilibrate the sample at 26.7 ℃ for 4 minutes; 2) the oscillation was started with a frequency step of 0.1Hz to 10Hz, the oscillation was fixed at 5.0Pa and the temperature was 26.7 ℃. The loss modulus and storage modulus readings were recorded and obtained by the rheometer.

Exemplary silicone blends have tan delta values of from about 0.01 to about 5, preferably from about 0.05 to about 1, more preferably from about 0.1 to about 0.5, as recorded at a frequency of 10Hz and 26.7 ℃. Without being bound by theory, it is believed that the preferred tan delta values correlate with usage signals for final rinse and/or post rinse clean feel, and thus consumers may perceive that compositions comprising these silicone blends are superior compared to existing products.

The silicone blends also have preferred viscosity values, including for example less than about 10m²(10,000,000 centistokes) of less than about 1m²(1,000,000 centistokes) and less than about 0.5m²S (500,000 centistokes).

Application method

The hair conditioning compositions of the present invention may be used in a conventional manner to provide conditioning and other benefits. Such methods of use depend on the type of composition used, but generally involve applying an effective amount of the product to the hair or scalp, which can then be rinsed off the hair or scalp (in the case of hair rinses) or allowed to remain on the hair or scalp (in the case of gels, creams, pastes and sprays). By "effective amount" is meant an amount sufficient to provide a dry conditioning benefit. Typically, from about 1g to about 50g is applied to the hair or scalp.

The composition is applied to wet or damp hair before the hair is dried. Typically, the composition is used after the hair has been washed. Typically, the composition is distributed throughout the hair or scalp by rubbing or massaging the hair or scalp.

the fourth siloxane polymer is prepared according to the methods disclosed in U.S. patent 4,833,225, U.S. patent application publication 2004/0138400, and U.S. patent application publication 2004/0048996. The fourth silicone polymer may be added to the formulation as a neat substance, a preformed emulsion, or a blend with a lower molecular weight material. In the latter case, the lower molecular weight material may be any material that can form a stable blend with the fourth siloxane polymer. Examples of low molecular weight materials include siloxanes such as decamethylcyclopentasiloxane, oxygenated solvents such as dipropylene glycol n-butyl ether and silicone copolyols. Silicone copolyols are preferred. For the fourth silicone polymer emulsion, the polymer is emulsified by methods well known in the art in the presence of an anionic, cationic, nonionic or amphoteric surfactant, preferably a nonionic or cationic surfactant. In embodiments comprising the silicone fourth polymer and silicone copolyol, the two are mixed prior to addition to the product.

Deionized water was heated to 85 ℃. The cationic surfactant and the high melting point fatty compound are mixed into water. The water was maintained at a temperature of about 85 ℃ until the components were homogenized and no solids were observed. The mixture is cooled to about 55 ℃ and held at this temperature to form a gel matrix. A fourth silicone polymer as specified is added to the gel matrix as an emulsion or as a blend with a copolyol. When included, polyalphaolefins, polypropylene glycols, silicones, and/or polysorbates can be added to the gel matrix. During this period of continuous stirring, the gel matrix was maintained at about 50 ℃ to ensure homogenization. When included, other additional components such as flavors and preservatives may also be added at this point. After homogenization, cool to room temperature.
