Description

COMPOSITIONS OF AIR CONDITIONER SHAMPOO FIELD OF THE INVENTION The present invention relates to conditioner shampoo compositions that both clean the hair and condition it.

BACKGROUND OF THE INVENTION Human hair becomes dirty due to its contact with the surrounding environment 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, shampoo needs to be given 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 "flying hair" or contribute to an undesirable "split ends" phenomenon particularly in the 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. In order to provide conditioning benefits for the hair in a cleansing shampoo base, a wide variety of conditioning actives have been proposed. However, many of these assets have the disadvantage of leaving the hair feeling dirty or coated, which interferes with the cleaning efficacy of the shampoo. It is known that the formation of coacervate in a shampoo composition has the advantage of providing the hair with conditioning benefits. The use of cationic polymers to form coacervates is known in the technical field, for example, in PCT publications WO93 / 08787 and WO95 / 01152. However, these shampoo compositions do not have the ability to provide satisfactory conditioning benefits while the hair is wet.

Based on the foregoing, there is a need for a conditioning shampoo that can provide improved conditioning benefit when the hair is wet, while not interfering with the cleansing efficacy or imparting to the hair negative sensation when dry. No existing technique provides all the advantages and benefits of the present invention.

SUMMARY OF THE INVENTION The present invention is directed to a conditioner shampoo composition comprising by weight: (a) between about 0.05% and 50% of an anionic polyhydrophilic surfactant; (b) between about 0.05% and 20% of a cationic conditioning agent selected from the group consisting of cationic surfactants, cationic polymers and mixtures thereof; (c) between about 0.01% and 20% of a silicone compound; Y (d) an aqueous vehicle. These and other features, aspects and advantages of the present invention will be apparent to those skilled in the art from reading the present disclosure.

It is also considered in its entirety that it forms part of this, as a reference "Silicon Compounds" distted by Petrarch System, Inc., 1984, this provides an extensive, although not exclusive, list of suitable silicone compounds. Another non-volatile dispersed silicone that can be especially useful is silicone rubber. The term "silicone gum", in the sense in which it is used herein, refers to a polyorganosiloxane material having a viscosity at 25 ° C greater than or equal to 1,000,000 centistokes. It is recognized that the silicone gums that are descd herein can also overlap with the silicone compounds discussed above. It is not intended that this overlap be a limitation for any of these materials. The silicone gums are P1062 described by Petrarch et al., Including United States Patent No. 4,152,416 by Spitzer et al., Issued May 1, 1979 and Noli, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Silicone gums are also described in General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. All of these described references are considered part of the present, as a reference. "Silicone gums" will normally have a mass molecular weight greater than about 200,000, usually between about 200,000 and 1,000,000. Specific examples include polydimethylsiloxane, copolymer of poly (dimethylsiloxane methylvinylsiloxane), copolymer of poly (dimethylsiloxane diphenylsiloxane methyl vinyl siloxane) and mixtures thereof. Also useful are silicone resins, which are fairly cross-linked polymeric siloxane systems. The crosslinking is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional and difunctional silanes or both, during the manufacture of the silicone resin. As is well understood in the technical field, the degree of crosslinking that is required to result in a silicone resin will vary according to the specific silane units that are incorporated in the silicone resin. In general, P1062 silicone materials having a sufficient level of trifunctional and tetrafunctional monomeric siloxane units and consequently a sufficient level of crosslinking, so that they dry out to form a rigid or hard film, are considered as 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 at least about 1.1 oxygen atoms per silicon atom in general will be silicone resins herein. Preferably, the ratio of oxygen: silicon atoms is at least 1.2: 1.0. The silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl- and methylvinylchlorosilanes and tetrachlorosilane, wherein the methyl substituted silanes are the most commonly used. Preferred resins are sold by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will generally be supplied in dissolved form in a volatile or non-volatile low viscosity silicone fluid. The silicone resins that are used herein should be supplied and incorporated into the compositions herein in that dissolved form, as will be readily apparent to those skilled in the art. Without being limited to theory, P1062 believes that silicone resins can strengthen the deposition in hair of other silicone compounds and can intensify the shine of hair with high refractive index volumes. Other useful silicone resins are silicone resin powders, for example, the material which is designated CTFA polymethylsilsequioxane, which is commercially available as Tospearl from Toshiba Silicones The method of manufacturing these silicone compounds, can be found in Encyclopedia of Polymer Science &Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley &Sons, Inc., 1989, which in its entirety is considered part of this, as a reference The silicone materials and in particular the silicone resins, can be conveniently identified according to an abbreviated nomenclature system, well known to those skilled in the art as "MDTQ" nomenclature.With this system, the silicone is described according to the presence of several monomeric siloxane units that form the silicone Briefly, the symbol M indicates the monofunctional unit (CH3) 3Si0.s; D indicates the difunctional unit (CH3) 2SiO; T indicates the trifunctional unit (CH3) SiO? .5; and Q indicates the quatri- or tetrafunctional unit Si02. The apostrophes in the symbols of the units, for example, M ', D', T1 and Q1 indicate substituents other than methyl and must be defined specifically for each case. Typical alternating substituents include groups such as vinyl, phenyl, amino, hydroxyl, etc. The molar ratios of the various units, either in terms of subscripts to the symbols that indicate the total number of each unit type in the silicone or an average thereof or as specifically indicated in combination with the molecular weight, complete the description of the silicone material in the MDTQ system. Higher relative molar amounts of T, Q, T1 and / or Q1 to D, D ', M and / or M1 in a silicone resin is indicative of higher levels of crosslinking. However, as discussed above, the total level of crosslinking may also be indicated by the oxygen to silicon ratio. The silicone resins which are used herein, which are preferred, are the MQ, MT, MTQ, MQ and MDTQ resins. In this way, the preferred silicone substituent is methyl. Especially preferred are MQ resins wherein the M: Q ratio is between about 0.5: 1.0 and 1.5: 1.0 and the average molecular weight of the resin is between about 1000 and 10,000.
