Description

COMPOSITION PE SHAMPOO COMPRISING SILICONE EMULSION.

TECHNICAL FIELD The present invention relates to a shampoo composition comprising a silicone emulsion.

BACKGROUND - Human hair gets dirty due to its contact with the environment that surrounds it and due to the sebum secreted by the scalp. When the hair is dirty, it has an unpleasant sensation and an unattractive appearance. When the hair is dirty you need to shampoo regularly. Shampooing the hair causes it to be cleaned by removing excess dirt and sebum. However, the shampoo can leave the hair in a wet, matted and generally unwieldy condition. Once the hair dries, it usually remains in a dry, stiff, lusterless or creped condition, due to the removal of natural hair oils and other natural conditioning and moisturizing components. Hair can also be left with very high levels of static when it dries, which can interfere with the hairstyle and result in a condition commonly referred to as "hair that flies "or contributes to an" undesirable "split ends" phenomenon particularly in long hair. A variety of approaches have been developed to reduce these problems after shampooing. This range of approaches ranges from the post-shampoo application of a hair conditioner, for example products to apply and not to rinse and products to eliminate by rinsing, to conditioning shampoos that try to both clean and condition the hair in a single product. Hair conditioners are typically applied in a separate step after applying the shampoo. Hair conditioners are either type apply and remove with rinse or apply and do not rinse, depending on the type of product used. However, hair conditioners have the disadvantage of requiring a separate and inconvenient treatment step. Conditioner shampoos are quite desirable products because they are convenient for use by consumers, as they provide in a "single step ~ the benefit of cleaning and conditioning the hair.In order to provide benefits -rie conditioning for the hair on a base of cleaning shampoo, a wide variety of conditioning actives have been proposed, but they have been totally satisfactory.

One problem relates to the compatibility between anionic detergent surfactants and the many conventional cationic conditioning agents. While efforts have been made to decrease adverse interaction through the use of alternative surfactants, it is still very desirable to use anionic surfactants to some degree, due to their generally superior cleaning properties. On the one hand, some customers desire mild, non-stimulant shampoo compositions that usually comprise other classes of surfactants, in addition to anionic surfactants. Therefore, a shampoo composition that is compatible with a wide variety of detergent surfactants is desired. The materials that can provide improved overall conditioning benefits while maintaining the cleaning performance with the use of anionic detergent surfactants are the silicone conditioning agents, however, shampoos comprising silicone conditioning agents have a tendency to provide a sensation undesirable in the hair, for example that the hair is left with a feeling that it is coated, heavy or dirty after it has dried In addition, in order to provide a stable and well-dispersed shampoo composition, which includes conditioning agents silicone, a suspension agent such as, for example, acyl derivatives is required The combination of the silicone conditioning agents and their suspending agents usually provides a formulation having a relatively viscous and milky appearance. suspension agents such as ethylene glycol stearates.The unpleasant feeling in the hair, as well as the instability observed with the silicone conditioning agents, is believed to be due to the particle size of the silicone conditioning agent. This is particularly noticeable when silicone has a high molecular weight. Although high molecular weight silicone polymers are known to have favorable conditioning benefits, for example softness and ease of styling, they also tend to have a large particle size and are thermodynamically unstable. The mechanical shear stress is known to provide a smaller particle size to the fluids. The high molecular weight silicone polymers are too viscous to emulsify to a desirable particle size. Therefore, high molecular weight silicone polymers, with the help of a suspending agent, can not enter a "formulation at levels that provide the desired conditioning benefits." Therefore, there is still a desire to providing a shampoo composition comprising high molecular weight silicone polymers which are stable without suspending agent and which provide improved overall conditioning benefits. Japanese Patent Laid-open to Inspection 7-138,136 discloses a hair cleaning composition comprising a surfactant and a polymerized silicone emulsion fairly soluble in water, obtained by emulsion polymerization and having an average particle size of 0.2-50. mieras European Patent Application 674,898-A discloses a hair conditioning shampoo composition comprising a stable microemulsion of a high viscosity silicone with a particle size of less than 0.15, in combination with a deposition polymer and a surfactant. U.S. Patent 5,504.1 < 39 discloses a method for making a silicone emulsion having a high viscosity, wherein a mixture of water, cyclic siloxane, optional non-ionic surfactant and cationic surfactant is polymerized using silanolate or organosilanolate, as an initiator. In the present invention, a "co?" Shampoo position comprising a silicone emulsion comprising high molecular weight silicone polymer, made by a given surfactant system, has been developed and provides stability without the use of silicone suspension agents as well as improved overall conditioning benefits by being compatible with a wide range of conditioning agents.

Crosslinking is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional - or difunctional silanes, or both, during the manufacture of the silicone resin. As is well understood in this field, the degree The crosslinking that is required in order to result in a silicone resin will vary according to the specific silane entities that are incorporated into the silicone resin. In general, silicone materials having a sufficient level of trifunctional and tetrafunctional monomeric siloxane units and, therefore, a sufficient level of crosslinking, so that they dry to form a rigid or hard film, are considered as resins of silicone The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials having at least about 1.1 oxygen atoms per "each silicon atom in general will be silicone resins for the present.Preferably, the ratio between oxygen atoms: silicon is at least about 1.2: 1.0 The silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl- and methylvinyl-chlorosilanes and tetrachlorosilane, where the methyl-substituted silanes are the most commonly used. Without being limited by theory, it is considered that silicone resins can improve the deposition of other silicones in the hair and can improve the lustrousness of the hair with high volumes of refractive index.

Other useful silicone resins are the silicone resin powders as the materials to which the CTFA designation of polymethylsilsequixan is given.

The silicone resins can be conveniently identified according to an abbreviated nomenclature system well known to those skilled in the art such as the "MDTQ" nomenclature. In this system, the silicon is described according to the presence of several monomeric siloxane units that "form the silicone." In summary, the symbol M denotes the monofunctional unit (CH3) 3SiO) 0.5; D denotes the difunctional unit (CH3) 2SiO; T denotes the trifunctional unit (CH3) SiO) 1-5; and Q denotes the quadri or tetrafunctional unit Si02 The bonus signs in the unit symbols for example, M ', D', T 'and Q1 denote substituents other than methyl and they must be specifically defined each time they are present.The typical alternate substituents include groups such as vinyl, phenyl, amino, hydroxyl, etc. The molar proportions of the different units, either in terms of subscripts in the symbols indicating the The total number of each type of units in the silicon or an average thereof, or as specifically indicated proportions in combination with the molecular weight, complete the description of the silicone material with the MDTQ system. high relative molarities of T, Q, T "and / or Q 'with respect to D, D1 M and / or M1 in a silicone resin are indicative of high levels of crosslinking. However, as discussed here, the general level of crosslinking can also be indicated by the oxygen to silicon ratio. The silicone resins which are used here and are preferred are the resins MQ, MT, MTQ, MQ and MDTQ. Therefore, the preferred silicone substituent is ~ methyl. MQ resins are especially preferred where the M: Q ratio is between --- about 0.5: 1.0 and about 1.5: 1.0 Other silicone fluids, gums and resins can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989, which is "incorporated here completely as a reference.

Surfactant Compatibilizer The compatibilizing surfactant useful in making the silicone emulsions of the present invention is that which functions to make the emulsion of anionically emulsion polymerized silicone compatible with the cationic surfactant. Without being bound by any theory, it is believed that if the cationic surfactant is added directly to the anionic mixture obtained after the initial polymerization by emulsion of the starting silicone material with the anionic surfactants, the anionic surfactants included in the emulsion of polymerized silicone Anionically by emulsion having ionic charges opposite to those of cationic surfactants, they react to destroy the emulsion and / or produce undesirable precipitation. Therefore, the emulsion of anionically polymerized silicone by emulsion obtained is treated with a compatibilizing snot.

SUSPENSION AGENTS The shampoo composition of the present invention is essentially free of silicone suspension agents derived from acyl. By the term "essentially free", it is meant that the suspending agent is not included in an amount sufficient to provide a suspending effect to the silicone polymers. It is recognized that the same suspending agents may be included in small amounts to provide a pearlescent effect to the composition. In the present invention, it is not intended to exclude small amounts of Suspension agents that could only provide a pearlescent effect, but that can not provide suspension effect to the silicone polymers. In general, the suspension effect to silicone polymers can not be observed at lower levels of about 1.5%. The suspending agents herein include those that are present in crystalline form. These suspending agents are described in U.S. Patent 4,741,855, which is incorporated herein by reference in its entirety. These preferred suspending agents include ethylene glycol esters of fatty acids, preferably having from about 16 to about 22 carbon atoms, such as the ethylene glycol stearates, both mono and distearates.

OPTIONAL COMPONENTS A wide variety of additional ingredients can be formulated in the compositions herein. These include: other conditioning agents such as hydrolyzed collagen, hydrolyzed keratin, proteins, plant extracts and nutrients; polymers for fixing hair; other surfactants such as anionic surfactants; thickening agents such as, for example, xanthan gum, guar gum, hydroxyethylcellulose, methylcellulose, starch and starch derivatives; viscosity modifiers such as methanolamides of long chain fatty acids such as, for example, cocomonoethanolamide; preservatives such as benzyl alcohol, methylparaben, propylparaben e-imidazolidinyl urea; solvents such as polyvinyl alcohol, ethyl alcohol and volatile and non-volatile low molecular weight silicone fluids; pH adjusting agents such as citric acid, sodium citrate, succinic acid, phosphoric acid, sodium hydroxide, sodium carbonate; salts, in general, such as, for example, potassium acetate and sodium chloride; coloring agents, such as any of the dyes FD &C or D &C; hair oxidizing agents (decolorizing agents) such as hydrogen peroxide, perborate and persulfate salts; hair reducing agents such as thioglycollates; perfumes; sequestering agents, for example disodium ethylenediamine tetraacetate and polymer plasticizing agents, for example glycerin, diisobutyl adipate, butyl stearate and propylene glycol; and ultraviolet and infrared light filters and absorbing agents such as octylsalicylate. These optional ingredients are generally used individually at levels between about 0.01% and about 10.0%, preferably between about 0.05% and about 5.0% by weight of the composition.
