Definitions

  • the present invention relates to concentrated conditioning compositions which deliver conditioning benefit to the hair by dissolving or dispersing the composition to the rinse water and rinsing the shampooed hair with such treated rinse water.
  • shampooing cleans the hair by removing excess soil and sebum.
  • shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components.
  • the hair can further be left with increased levels of static upon drying, which can interfere with combing and result in a condition commonly referred to as "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair.
  • locations where water supply is unstable, or lacking infrastructure there is a desire to provide conditioning benefit to the hair without extra use of water for rinsing off another product.
  • Still further, in such locations there is a need to provide purified water for applying to the hair.
  • hair conditioning compositions which provide conditioning benefits without using water excess to the amount that would be used for shampooing the hair.
  • Such hair conditioning compositions in a form which readily dissolves or disperses in water.

Description

CONCENTRATED CONDITIONING COMPOSITION
FIELD OF THE INVENTION
The present invention relates to concentrated conditioning compositions which deliver conditioning benefit to the hair by dissolving or dispersing the composition to the rinse water and rinsing the shampooed hair with such treated rinse water.
BACKGROUND Human hair becomes soiled due to its contact with the surrounding environment and from the sebum secreted by the scalp. The soiling of hair causes it to have a dirty feel and an unattractive appearance. The soiling of the hair necessitates shampooing with frequent regularity.
Shampooing cleans the hair by removing excess soil and sebum. However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying, which can interfere with combing and result in a condition commonly referred to as "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair.
A variety of approaches have been developed to alleviate these after- shampoo problems. These approaches range from post-shampoo application of hair conditioners such as leave-on and rinse-off products, to hair conditioning shampoos which attempt to both clean and condition the hair from a single product. Although some consumers prefer the ease and convenience of a shampoo which includes conditioners, a substantial proportion of consumers prefer the more conventional conditioner formulations which are applied to the hair as a separate step from shampooing, usually subsequent to shampooing. The conditioning formulations thus applied to the hair would then typically be rinsed off from the hair, and the hair would be left to dry.
Some consumers desire not to go through the extra step of applying and rinsing off another product subsequent to shampooing the hair. In locations where water supply is unstable, or lacking infrastructure, there is a desire to provide conditioning benefit to the hair without extra use of water for rinsing off another product. Further, in such locations, there is a need to provide suitable methods of conditioning the hair without the use of a shower but with, for example, a basin. Still further, in such locations, there is a need to provide purified water for applying to the hair. Based on the foregoing, there remains a desire to provide hair conditioning compositions which provide conditioning benefits without using water excess to the amount that would be used for shampooing the hair. There is also a desire to provide such hair conditioning compositions in a form which readily dissolves or disperses in water. There is also a desire to provide purified water for applying to the hair in a convenient manner.
None of the existing art provides all of the advantages and benefits of the present invention.
SUMMARY The present invention is directed to a hair conditioning composition for preparing a treated water for applying to the hair; the treated water prepared by dissolving or dispersing the conditioning composition, the composition comprising 0.01 % to 100% by weight of a conditioning agent selected from the group consisting of cationic surfactants, cationic polymers, silicone compounds, and mixtures thereof.
The present invention is also directed to a method of conditioning the hair comprising the steps of;
(a) applying a shampoo composition comprising a detersive surfactant to the hair; (b) providing a treated water made by dissolving or dispersing the conditioning composition to water, wherein the treated water has a concentration by weight of from about 0.001 % to abut 2% of the conditioning agent of the conditioning composition; and (c) rinsing the hair with the treated water; wherein steps (a) and (b) may be reversed.
The present invention is also directed to a method of purifying water for applying to the hair comprising the step of adding a flocculent system or a rinse aid system to the water.
These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure.

The viscosity can be measured by means of a glass capillary viscometer as set forth in Dow Corning Corporate Test Method CTM0004, July 20, 1970. Silicone compound of high molecular weight may be made by emulsion polymerization. Suitable silicone fluids include polyalkyl siloxanes, polyaryl siloxanes, polyalkylaryl siloxanes, polyether siloxane copolymers, and mixtures thereof.

wherein R123 is alkyl or aryl, and x is an integer from about 7 to about 8,000. Z8 represents groups which block the ends of the silicone chains. The alkyl or aryl groups substituted on the siloxane chain (R123) or at the ends of the siloxane chains Z8 can have any structure as long as the resulting silicone remains fluid at room temperature, is dispersible, is neither irritating, toxic nor otherwise harmful when applied to the hair, is compatible with the other components of the composition, is chemically stable under normal use and storage conditions, and is capable of being deposited on and conditions the hair. Suitable Z8 groups include hydroxy, methyl, methoxy, ethoxy, propoxy, and aryloxy. The two R groups on the silicon atom may represent the same group or different groups. Preferably, the two R123 groups represent the same group. Suitable R123 groups include methyl, ethyl, propyl, phenyl, methylphenyl and phenylmethyl. The preferred silicone compounds are polydimethylsiloxane, polydiethylsiloxane, and polymethylphenylsiloxane. Polydimethylsiloxane, which is also known as dimethicone, is especially preferred. The polyalkylsiloxanes that can be used include, for example, polydimethylsiloxanes. These silicone compounds are available, for example, from the General Electric Company (Waterford, New York, USA) in their Viscasil® and SF 96 series, and from Dow Corning Corp.

Polyalkylaryl siloxane fluids can also be used and include, for example, polymethylphenylsiloxanes. These siloxanes are available, for example, from the General Electric Company as SF 1075 methyl phenyl fluid or from Dow Corning as 556 Cosmetic Grade Fluid. Especially preferred, for enhancing the shine characteristics of hair, are highly arylated silicone compounds, such as highly phenylated polyethyl silicone having refractive index of about 1.46 or higher, especially about 1.52 or higher. When these high refractive index silicone compounds are used, they should be mixed with a spreading agent, such as a surfactant or a silicone resin, as described below to decrease the surface tension and enhance the film forming ability of the material.
The silicone compounds that can be used include, for example, a polypropylene oxide modified polydimethylsiloxane although ethylene oxide or mixtures of ethylene oxide and propylene oxide can also be used. The ethylene oxide and polypropylene oxide level should be sufficiently low so as not to interfere with the dispensability characteristics of the silicone. These material are also known as dimethicone copolyols. These materials can be directly dissolved or dispersed in water.

References disclosing suitable nonvolatile dispersed silicone compounds include U.S. Patent No. 2,826,551 to Geen; U.S. Patent No. 3,964,500 to Drakoff, issued June 22, 1976; U.S. Patent No. 4,364,837 to Pader, issued December 21 , 1982; and British Patent No. 849,433 to Woolston. "Silicon Compounds" distributed by Petrarch Systems, Inc., 1984, provides an extensive, though not exclusive, listing of suitable silicone compounds. Another nonvolatile dispersed silicone that can be especially useful is a silicone gum. The term "silicone gum", as used herein, means a polyorganosiloxane material having a viscosity at 25 °C of greater than or equal to 1 ,000,000 centistokes. It is recognized that the silicone gums described herein can also have some overlap with the above-disclosed silicone compounds. This overlap is not intended as a limitation on any of these materials. Silicone gums are described by Petrarch, and others including U.S. Patent No. 4,152,416 to Spitzer, et al., issued May 1 , 1979 and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Also describing silicone gums are General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. The "silicone gums" will 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, polydimethylsiloxane methylvinylsiloxane) copolymer, polydimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof.
Also useful are silicone resins, which are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of tri- functional and tetra-functional silanes with mono-functional or di-functional, or both, silanes during manufacture of the silicone resin. As is well understood in the art, the degree of crosslinking that is required in order to result in a silicone resin will vary according to the specific silane units incorporated into the silicone resin. In general, silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units, and hence, a sufficient level of crosslinking, such that they dry down to a rigid, or hard, film are considered to be silicone resins. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials which have at least about 1.1 oxygen atoms per silicon atom will generally be silicone resins herein.
Preferably, the ratio of oxyge silicon atoms is at least about 1.2:1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, and methylvinylchlorosilanes, and tetrachlorosilane, with the methyl substituted silanes being most commonly utilized. Preferred resins are offered by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will generally be supplied in a dissolved form in a low viscosity volatile or nonvolatile silicone fluid. The silicone resins for use herein should be supplied and incorporated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art. Without being bound by theory, it is believed that the silicone resins can enhance deposition of other silicone compounds on the hair and can enhance the glossiness of hair with high refractive index volumes.
Other useful silicone resins are silicone resin powders such as the material given the CTFA designation 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 and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989.
Silicone materials and silicone resins in particular, can conveniently be identified according to a shorthand nomenclature system well known to those skilled in the art as the "MDTQ" nomenclature. Under this system, the silicone is described according to the presence of various siloxane monomer units which make up the silicone. Briefly, the symbol M denotes the mono-functional unit (CH3)3SiO0.5; D denotes the difunctional unit (CH3)2SiO; T denotes the trifunctional unit (CH3)SiOι.5; and Q denotes the quadri- or tetra-functional unit SiO2. Primes of the unit symbols, e.g., M', D', T\ and Q' denote substituents other than methyl, and must be specifically defined for each occurrence. Typical alternate 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 indicating the total number of each type of unit in the silicone, or an average thereof, or as specifically indicated ratios in combination with the weight average molecular weight, complete the description of the silicone material under the MDTQ system. Higher relative molar amounts of T, Q, T' and/or Q' to D, D', M and/or or M' in a silicone resin is indicative of higher levels of crosslinking. As discussed above, however, the overall level of crosslinking can also be indicated by the oxygen to silicon ratio. The silicone resins for use herein which are preferred are MQ, MT, MTQ,
MQ and MDTQ resins. Thus, the preferred silicone 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 weight average molecular weight of the resin is from about 1000 to about 10,000.

To provide such signal, colorants and perfumes may be contained in the gas forming particle. The gas forming particles may be provided within the conditioning composition, or as an independent composition. When the gas forming particle is provided as a carrier for the conditioning composition, the composition contains little or no water.

The present invention may use a rinse aid system for effective rinsing of the shampoo composition and soils from the hair. The rinse aid system may be provided within the conditioning composition, or as an independent composition. When the rinse aid system is provided as a carrier for the conditioning composition, the composition preferably comprises silicone compounds but free of cationic surfactants as the conditioning agent. When the rinse aid system is provided as an independent composition, it is preferably released in the water simultaneously with the conditioning composition. In one embodiment, the rinse aid system may be used independently for providing a purified water suitable for applying to the hair.

Suds Suppressing Agent
Suds suppressing agents useful herein include antifoam compounds. Antifoam compounds for use herein are silica components. Preferably, these silica components are used in combination with the silicone compound described above as a conditioning agent.

Metal Ion Control Agents
Heavy metal ion (HMI) sequestrants which act to sequester (chelate) heavy metal ions are useful herein. These components may have calcium and magnesium chelation capacity, but preferentially they bind heavy metal ions such as iron, manganese and copper. These compounds are even more desired when the water is a tap water of low quality and consequently that which comprises a high level of HMI. Heavy metal ion sequestrants, which are acidic in nature, having for example phosphonic acid or carboxylic acid functionalities, may be present either in their acid form or as a complex salt with a suitable counter cation such as an alkali or alkaline metal ion, ammonium, or substituted ammonium ion, or any mixtures thereof.

Suitable polymeric dispersing agents include polymeric polycarboxylates and polyethylene glycols, although others known in the art can also be used. It is believed, though it is not intended to be limited by theory, that polymeric dispersing agents enhance overall rinsing performance.
Polymeric polycarboxylate materials can be prepared by polymerizing or copolymerizing suitable unsaturated monomers, preferably in their acid form. Unsaturated monomeric acids that can be polymerized to form suitable polymeric polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polymeric polycarboxylates herein of monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than about 40% by weight. Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful herein are the water-soluble salts of polymerized acrylic acid. The average molecular weight of such polymers in the acid form preferably ranges from about 2,000 to 10,000, more preferably from about 4,000 to 7,000 and most preferably from about 4,000 to 5,000. Water-soluble salts of such acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble polymers of this type are known materials.
Acrylic/maleic-based copolymers may also be used as a preferred component of the dispersing/anti-redeposition agent. Such materials include the water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight of such copolymers in the acid form preferably ranges from about 2,000 to 100,000, more preferably from about 5,000 to 75,000, most preferably from about 7,000 to 65,000. The ratio of acrylate to maleate segments in such copolymers will generally range from about 30:1 to about 1 :1 , more preferably from about 10:1 to 2:1. Water-soluble salts of such acrylic acid/maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate/maleate copolymers of this type are known materials which are described in European Patent Application No. 66915, published Dec. 15, 1982, as well as in EP 193,360, published Sep. 3, 1986, which also describes such polymers comprising hydroxypropylacrylate. Still other useful dispersing agents include the maleic/acrylic/vinyl alcohol terpolymers. Such materials are also disclosed in EP 193,360, including, for example, the 45/45/10 terpolymer of acrylic/maleic/vinyl alcohol.
Another polymeric material which can be included is polyethylene glycol (PEG). PEG can exhibit dispersing agent performance as well as act as a clay soil removal and anti-redeposition agent. Typical molecular weight ranges for these purposes range from about 500 to about 100,000, preferably from about
1 ,000 to about 50,000, and more preferably from about 1 ,500 to about 10,000.
Polyaspartate and polyglutamate dispersing agents may also be used, especially in conjunction with zeolite builders. Dispersing agents such as polyaspartate preferably have a molecular weight (avg.) of about 10,000.
A group of preferred clay soil removal/anti-redeposition agents are the cationic compounds disclosed in European Patent Application 111 ,965, Oh and Gosselink, published June 27, 1984. Other clay soil removal/antiredeposition agents which can be used include the ethoxylated amine polymers disclosed in European Patent Application 111 ,984, Gosselink, published June 27, 1984; the zwitterionic polymers disclosed in European Patent Application 112,592, Gosselink, published July 4, 1984; and the amine oxides disclosed in U.S. Patent 4,548,744, Connor, issued October 22, 1985. Other clay soil removal and/or anti-redeposition agents known in the art can also be utilized in the compositions herein. Another type of preferred anti-redeposition agent includes the carboxymethylcellulose (CMC) materials. Builders
The rinse aid used in the compositions of the present invention may also comprise builders to assist in controlling mineral hardness. Inorganic as well as organic builders can be used.
Inorganic or P-containing builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta- phosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulphates, and aluminosilicates. However, non-phosphate builders are required in some locales. Importantly, the compositions herein function surprisingly well even in the presence of the so- called "weak" builders (as compared with phosphates) such as citrate, or in the so-called "underbuilt" situation that may occur with zeolite or layered silicate builders.
Examples of silicate builders are the alkali metal silicates, particularly those having a SiO2 :Na2O ratio in the range 1.6:1 to 3.2:1 and layered silicates, such as the layered sodium silicates; NaSKS-6 is the trademark for a crystalline layered silicate marketed by Hoechst (commonly abbreviated herein as "SKS-6"). Unlike zeolite builders, the Na-SKS-6 silicate builder does not contain aluminum. Na-SKS-6 has the delta-Na2 SiO5 morphology form of layered silicate. SKS-6 is a highly preferred layered silicate for use herein, but other such layered silicates, such as those having the general formula NaMSix O2x+1.yH2 O wherein M is sodium or hydrogen, x is a number from 1.9 to 4, preferably 2, and y is a number from 0 to 20, preferably 0 can be used herein. Various other layered silicates from Hoechst include NaSKS-5, NaSKS-7 and NaSKS-1 1 , as the alpha, beta and gamma forms. As noted above, the delta-Na2 SiO5 (NaSKS-6 form) is most preferred for use herein.
Aluminosilicate builders are useful in the present invention. Useful aluminosilicate ion exchange materials are commercially available. These aluminosilicates can be crystalline or amorphous in structure and can be naturally-occurring aluminosilicates or synthetically derived. A method for producing aluminosilicate ion exchange materials is disclosed in U.S. Pat. No. 3,985,669, Krummel, et al, issued Oct. 12, 1976. Preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. Particularly preferred is Zeolite A. Dehydrated zeolites may also be used herein. Preferably, the aluminosilicate has a particle size of about 0.1-10 microns in diameter.
Citrate builders, e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for liquid detergent formulations due to their availability from renewable resources and their biodegradability. Also suitable in the compositions of the present invention are the 3,3- dicarboxy-4-oxa-1 ,6-hexanedioates and the related compounds. Useful succinic acid builders include the C5 -C20 alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Specific examples of succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2- pentadecenylsuccinate, and the like. Laurylsuccinates are the preferred builders of this group.
Fatty acids, e.g., C12 -C18 monocarboxylic acids, can also be incorporated into the compositions alone, or in combination with the aforesaid builders, especially citrate and/or the succinate builders, to provide additional builder activity.
In situations where phosphorus-based builders can be used, the various alkali metal phosphates such as the well-known sodium tripolyphosphates, sodium pyrophosphate and sodium orthophosphate can be used. Phosphonate builders such as ethane-1-hydroxy-1 ,1-diphosphonate and other known phosphonates can also be used. FLOCCULENT SYSTEM
The flocculent system useful herein can remove soils contained in the water to be used to prepare the treated water. The flocculent system is particularly advantageous for use in locations where water supply is unstable, or lacking infrastructure. The flocculent system herein provides a floe when contacted with the soils in the water. Therefore, the user can use a treated water which has significantly decreased amount of soil by removing the floe. If the floe has lower density than water, the floe can be scopped away from the surface prior to use. If the floe has higher density than water, the upper layer water can be decanted or scooped for use. In one embodiment, the flocculent system may be used independently for providing a purified water suitable for applying to the hair.
The flocculent system can be in the form of a solid, or a liquid such as an aqueous solution, and can be provided as a kit with the conditioning composition, or housed separately in a multiple compartment package, as described below. In either case when a flocculent system is comprised in the present product, the conditioning agent is preferably selected from those which are highly soluble in water to avoid loss of the conditioning agent from the water by reacting with the flocculent system prior to use. When the flocculent system is comprised in the conditioning composition, the amount of conditioning agent in the composition is determined in consideration of the expected loss caused by reaction with the flocculent system upon release to the water. When the flocculent system is provided as an independent composition from the conditioning composition, the flocculent system can be contacted with water prior to the conditioning composition so that the soils are removed effectively and/or so that the amount of conditioning agent lost by reaction with the flocculent system is decreased.
The flocculent system comprises a primary flocculent and a secondary flocculent. The primary flocculent is selected from multivalent cations and polyethyleneimines. The secondary flocculent is selected from the group consisting of anionic polyelectrolytes, nonionic polyelectrolytes, cationic polyelectrolytes, and compatible mixtures thereof.
Examples of multivalent cations useful as the primary flocculent are salts, including polymeric salts, of aluminium, manganese II or iron III. Preferred examples are aluminium salts. One preferred source of aluminium ions is aluminium chloride. A further preferred source or aluminium ions is aluminium sulphate. A further preferred source of aluminium ions is polymeric aluminium chloride. A further preferred source of aluminiumm is polyaluminium silicate sulphate. Use of aluminium polyvalent metal ions is preferred. Whilst anhydrous or hydrated salts may both be used, hydrated salts are preferred. In particular, aluminium sulphate and aluminium chloride have been found to be particularly beneficial as they produce floes which are rapidly formed and which may float to the surface of the waste-water and can therefore be easily removed. In a particularly preferred aspect of the invention, hydrated salts of aluminium are used as flocculent. AICl3.6H2O and Al2(SO )3.16H2O are preferred, as these have been found to promote especially rapid floe flotation in waste-water from household washing processes, particularly laundry liquors.
Suitable secondary flocculents are organic polyelectrolytes. In accordance with one aspect of the invention, cationic polymers, preferably having a high molecular weight are preferred. However, in accordance with a further preferred embodiment of the invention anionic and/or nonionic polyelectrolytes are preferred as the secondary flocculent.
Many suitable synthetic cationic polymeric materials are available and these are generally high molecular weight polyamides or polyamines. Particularly preferred are derivatives of polyacrylamide. Preferred molecular weights (Mw) based on viscosity measurements are in the range 105 to 107. Preferably the molecular weight will be above 4x106, most preferably above 5x10 . Molecular weights around 6x10 or higher are particularly preferred. The cationic polyelectrolytes are polymers preferably having a degree of cationicity (percentage of the number of side groups which are reacted to provide a cationic group) greater than 20%, more preferably greater than 30%, and even more preferably greater than 40% or even above 60%. Particularly preferred materials have a molecular weight above 4 X 106 and a cationicity greater than 40%. Suitable materials may be made by copolymerisation of acrylamide and quaternary ammonium polyacrylamides. Examples of suitable polymers include Zetag 89, Praestol 61 1 BC, Calfloc 1552, 1506 and 1508, and Polymin KP97 (tradenames).
Nonionic and anionic polymers are also known in the art as flocculents, and in a highly preferred aspect of the invention, the secondary flocculent comprises a nonionic and/or anionic flocculent. Suitable anionic or nonionic polyelectrolytes are generally water-soluble high molecular weight acrylamide polymers. These may be polymers of methacrylamide but are preferably polymers of acrylamide. Other monomers may be copolymerised with the (meth) acrylamide to impart anionic properties. Preferred polymers, such as polyacrylamides, have a high molecular weight, for example, above 1 million and often 2 to 30 million, and normally having intrinsic viscosity (in dl/g), above 5 and generally above 8. For very high molecular weights which may also be suitable, the intrinsic viscosity may even be above 10 and typically 12 to 16 or higher. Preferred polymers may have solution viscosities (as measured in a Fann viscometer at 25°C, based on a 1 % solution in deionised water, and at a shear rate of 5.1 1 sec"1) of at least 350 cps, preferably at least 500, or even at least 1000 cps. The molecular weight is preferably greater than 2 x 106 and preferably no greater than 20 x 106. An additional benefit may arise on addition of the alkali-source as effervescence may result due to reaction with polyvalent metal ions or other acid source present in the waste water. Such alkali-source is described above under the section "GAS FORMING PARTICLES". This may be desirable to promote floe flotation. METHOD OF CONDITIONING AND PRODUCT FORM
The present invention is also directed to a method of conditioning the hair comprising the steps of:
(a) applying a shampoo composition comprising a detersive surfactant to the hair; (b) providing a treated water made by dissolving or dispersing the conditioning composition to water, wherein the treated water has a concentration by weight of from about 0.001 % to about 2% of the conditioning agent of the conditioning composition; and
(c) rinsing the hair with the treated water. Steps (a) and (b) can be reversed. In the method of the present invention, the conditioning composition is dissolved or dispersed in water, and the treated water thus obtained is applied to the hair. The term "treated water" as used herein describes water provided by the user and to which at least the conditioning composition is dissolved or dispersed, and in addition, optionally other components such as gas forming particles, rinse aid systems, and flocculent systems are dissolved or dispersed in the same water. Such treated water is applied to the hair after a shampoo composition comprising a detersive surfactant is applied and worked through the hair. Thus, rinsing the hair with treated water provides two functions at the same time, namely, it washes away the shampoo composition and soils from the hair while also providing conditioning benefit to the hair. This allows the user to provide conditioning benefits to the hair without using water excess to the amount that would be used for shampooing the hair. The treated water can be made in a basin, or in a package provided with the present composition for making the treated water, typically a basin available in the user's home.
The shampoo composition to be used in step (a) can be any composition comprising detersive surfactants and is suitable for washing off soils from the hair. The term detersive surfactant, as used herein, is intended to distinguish these surfactants from surfactants which are primarily emulsifying surfactants, i.e. surfactants which provide an emulsifying benefit and which have low cleansing performance. It is recognized that most surfactants have both detersive and emulsifying properties. It is not intended to exclude emulsifying surfactants from the present invention, provided the surfactant also possesses sufficient detersive properties to be useful herein. Detersive surfactants are typically selected from the group consisting of anionic surfactants, amphoteric surfactants, nonionic surfactants, and mixtures thereof. In one preferred embodiment, at least an anionic surfactant is included in the shampoo composition to be used in step (a), and a cationic conditioning agent is included in the conditioning composition to be used in step (c). The present invention is also directed to a method of purifying water for applying to the hair comprising the step of adding a rinse aid system or a flocculent system to the water, both systems described in detail above. The term "purified water" as used herein describes water provided by the user and to which the rinse aid system or the flocculent system is dissolved or dispersed in the water. It has been surprisingly found that, when the pre-purified water contains a high amount of heavy metal ions and salts, the purified water obtained by the method herein can provide benefit to the hair when applied, such as soft feel to the hair, even without conditioning agents, as compared to the pre-purified water. The present invention is also directed to a method of purifying water in the process of conditioning the hair comprising the steps of:
(a) applying a shampoo composition comprising a detersive surfactant to the hair;
(b) providing a treated water made by contacting with a flocculent system and dissolving or dispersing the conditioning composition to water, wherein the treated water has a concentration by weight of from about 0.001 % to abut 2% of the conditioning agent of the conditioning composition, and
(c) rinsing the hair with the treated water.
Steps (a) and (b) may be reversed. Step (b) may comprise two steps when the flocculent system is provided as an independent composition from the conditioning composition, namely;
(b-1 ) contacting a flocculent system with water to make a purified water; and (b-2) dissolving or dispersing the conditioning composition to the purified water. Providing the treated water in two steps may be advantageous in that the soils in the water are removed effectively and/or that the amount of conditioning agent lost by reaction with the flocculent system is decreased.
For providing a conditioning benefit to the hair while not negatively affecting the rinsing ability of the shampoo composition and soils from the hair, the treated water has a concentration by weight of from about 0.001% to about 2%, preferably from about 0.01 % to about 0.5% of conditioning agent. In order for the user to achieve this suitable concentration of treated water, the conditioning composition of the present invention is provided in a package means containing a unit dose of the conditioning composition, or with a measuring means. When the present composition is provided in a form that would require making the treated water in a vessel provided by the user, for example a basin, the dosage of the composition is determined based on the amount of water contained in an average size basin. When the present composition is provided with a package means for making the treated water, the dosage of the composition is based on the volume of such package. Such package is preferably in a form suitable for the user to hold in the hand, which is described in detail below. The measuring means can be a scale or indicator on the package showing the amount of conditioner composition to be used, or a dispensing means for providing a predetermined amount, such as an actuated pump head. The conditioning composition of the present invention can be provided in any form which is suitable for transportation and storage at ambient temperatures, and is readily applicable to the water upon use to make the treated water. As the conditioning composition is designed to readily dissolve or disperse in water, the composition is typically easily degraded by humidity. Packaging for any product form is selected to avoid humidity and preferably, accidental contact with water.
The conditioning composition of the present invention can be in the form of a liquid such as a gel or paste, the carrier of the liquid typically being water and/or water-soluble solvents. Suitable packaging for such product form include sachets, constructed packaging having one or more compartments. When a carrier containing little or no water is used, a water soluble coating may be used.
The conditioning composition of the present invention can be in the form of a solid such as powders, particles, tablets, and capsules, made by spray dry, granulation, tabletting, freeze-dry, and other suitable methods. When the conditioning composition is freeze-dried or spray-dried, the composition may consist of 100% conditioning agent. Otherwise, binders, processing aids, gas forming particles described above, and other components may be contained in the solid form. Solid articles of unit dose such as tablets and capsules containing the gas forming particles are particularly useful herein. Suitable packaging for such product forms include any packaging forms as mentioned above, flexible wrappers, and other structured packaging such as press-through blister packaging. WATER SOLUBLE COATING
The conditioning composition and other benefit providing components of the present invention can be provided in water soluble coating, preferably in unit dosage amounts. Such compositions are substantially free of water so that the contents do not leak or degrade the composition or coating material prior to use. The water soluble coating is in a closed structure, preferably in the form of a pouch. The shape of the pouch may be in any form suitable for handling, and may comprise multiple compartments as described below. The compositions housed in water soluble coating may further be contained in other packaging useful for transportation and storage.
The water soluble coating is made from a water-soluble film having a solubility of at least 50%, preferably 95%. Useful polymer material for making the water-soluble film include polyvinyl alcohols, polyvinyl pyrrolidone, polyalkylene oxides, acrylamide, acrylic acid, cellulose, cellulose ethers, cellulose esters, cellulose amides, polyvinyl acetates, polycarboxylic acids and salts, polyaminoacids or peptides, polyamides, polyacrylamide, copolymers of maleic/acrylic acids, polysaccharides including starch and gelatine, natural gums such as xanthum and carragum. More preferably the polymer is selected from polyacrylates and water-soluble acrylate copolymers, methylcellulose, carboxymethylcellulose sodium, dextrin, ethylcellulose, hydroxyethyl cellulose, hydroxypropyl methylcellulose, maltodextrin, polymethacrylates, still preferably polyvinyl alcohols, polyvinyl alcohol copolymers and hydroxypropyl methyl cellulose (HPMC). Mixtures of polymers can also be used to control the mechanical and/or dissolution properties of the compartment or pouch, depending on the application thereof and the required needs. It may be preferred that a mixture of polymers is used, having different weight average molecular weights, for example a mixture of PVA or a copolymer thereof of a weight average molecular weight of 10,000- 40,000, preferably around 20,000, and of PVA or copolymer thereof, with a weight average molecular weight of about 100,000 to 300,000, preferably around 150,000. Also useful are polymer blend compositions, for example comprising hydrolytically degradable and water- soluble polymer blend such as polylactide and polyvinyl alcohol, achieved by the mixing of polylactide and polyvinyl alcohol, typically comprising 1-35% by weight polylactide and approximately from 65% to 99% by weight polyvinyl alcohol, if the material is to be water-dispersible, or water-soluble. It may be preferred that the polymer present in the film is from 60-98% hydrolysed, preferably 80% to 90%, to improve the dissolution of the material. Most preferred are films which are water-soluble and stretchable films, as described above. Highly preferred water-soluble films are films which comprise PVA polymers and that have similar properties to the film known under the trade reference M8630, as sold by Chris-Craft Industrial Products of Gary, Indiana, US. The pouch can be made by a process comprising the steps of contacting a composition herein to a water-soluble film in such a way as to partially enclose said composition to obtain a partially formed pouch, optionally contacting said partially formed pouch with a second water-soluble film, and then sealing said partially formed pouch to obtain a pouch. Pouches having multiple compartments can be made. MULTIPLE COMPARTMENT PACKAGE
The conditioning composition and other benefit providing components of the present invention can be provided by being independently housed in a package having multiple compartments. A first compartment can be used for housing the conditioning composition, while a second compartment can be used for housing another component which may react or degrade when in contact with the conditioning composition or with each other, or which function better when contacted with the conditioning composition upon use, or which are contacted with water in a subsequent manner. Such compositions suitable to be housed in the second compartment include the flocculent system as described above, the rinse aid system described above, the gas forming particles as described above, and perfumes and colorants. The multiple compartment package herein may comprise third and forth compartments for independently housing the components above. The amount of compositions and components housed in any of the compartments are preferably in a unit dosage amount. The gas forming particle may be housed independently from the conditioning composition in a multiple compartment package. By providing the product in such way, conditioning compositions comprising water, which would otherwise be incompatible with the gas forming particles, may be released into the water with the gas forming particles upon use. Perfumes and colorants may be housed independently from the conditioning composition in a multiple compartment package. By providing the product in such way, aesthetic benefits are provided to the user upon use.
The rinse aid system may be housed independently from the conditioning composition in a multiple compartment package. By providing the product in such way, conditioning compositions comprising components reactive over time with one or more of the rinse aid system components may be released into the water upon use to minimize such reaction.
The flocculent system may be housed independently from the conditioning composition in a multiple compartment package. By providing the product in such way, conditioning compositions comprising components reactive over time with the flocculent system may be released into the water upon use to minimize such reaction. It is also advantageous to provide the product in such way when the flocculent system is released to the water prior to the conditioning composition. The multiple compartment package may be made by the material useful for water soluble coating, as described above, if the components to be housed are compatible with the water soluble coating material. It is possible to make the walls for separating the components by the same water soluble coating material, so that the entire package dissolves or disperses in water. Such multiple compartment water soluble pouches are particularly preferred in that the pouch can be released in water without mixing with each other or opening one or more mouths of a package. Water soluble coating which houses a structured solid article, such as a tablet, typically possesses the same structural stability as the structured solid article itself. Therefore, it is possible to make multiple compartment water soluble pouches which house a structured solid article in one compartment, and a non-structured article in another compartment, yet still maintaining structural stability.
The multiple compartment package may be made by rigidly or flexibly structured material which do not react with water. Structured multiple compartment packaging include any known in the field of personal care, fabric care, home care, or foods. Particularly useful are those used in the personal care field for liquid products for use of sampling and/or in unit dosage form, and those used in the foods field for unit dosage liquid seasoning.
One preferred embodiment is explained herein with reference to Figs. 1 and 2.
The multiple compartment package of Fig. 1 contains a first compartment 1 , a second compartment 2, a peripheral seal area 7 and an intermediate seal area 6. The cross section view of the same package is provided in Fig. 2. The intermediate seal area 6 is provided to have a weaker sealing than the peripheral seal area 7. Upon opening the package, physical pressure is added to either or both of the first and second compartments to break the intermediate seal area 6. The sealing strength of intermediate seal area 6 and peripheral seal area 7 are arranged so that, the peripheral seal area 7 is not broken at this time. By breaking of the intermediate seal area 6, a mixture of the conditioning composition and another component is provided within the package. The mixed product thus obtained is finally excreted out of the package to water to prepare a treated water. Referring to Fig. 1 , notches 3 and perforation area 4 may be provided to conveniently make a spout 5 by ripping tearing apart the package at the perforation area. HAND HELD CONTAINER
The conditioning composition of the present invention may be provided in a kit with a hand held container. The hand held container referred to herein comprises:
(a) a housing for preparing the treated water, the housing having a dispensing passage;
(b) the dispensing passage including a distal end; and
(c) an applicator attached to the distal end for applying the treated water to the hair.
When the conditioning composition is not provided in unit dosage form, the housing should provide a measuring means for measuring the amount of conditioning composition used for preparing the treated water in view of the volume of the housing. By using the hand held container, the user can prepare and apply the treated water without the use of a basin, or other articles. This further prevents contacting of hands and eyes during the preparation of the treated water, which may or may not generate heat and splashes by water dissolving reactions and releasing of gas by dissolving of gas forming particles.
These structural elements are explained herein with reference to Figs. 3 and 4. Referring to Fig. 3, this container comprises, as essential structural elements, a housing 1 , a dispensing passage 2 having a distal end 3, and an applicator 4 attached to the distal end. The container may further contain other structural elements.
The shape of the housing is extremely variable. Preferably, the shape and material are such as to allow the container to be easily and conveniently handled, thereby providing an ergonomic size and shape which makes it comfortable to hold in the hand. The container preferably seals easily and remains sealed during use so that the treated water does not leak out. Preferred housing materials include plastics and polymers, flexible materials such as films and laminated papers, rubber, glass, metal, and combinations thereof. More preferred housing materials include rubber, and plastics such as polyethylene, polypropylene, and polyethylene terephthalate. The housing must have sufficient structural rigidity for holding and for controlling the amount of treated water to dispense. More rigid containers with round and oval cross-sections are popular with users, however, other shapes, such as squares or rectangles can be used, for example, to improve storage profiles. It is preferred that the housing be designed so as to easily fit the user's hand, to facilitate handling, holding, shaking, etc,. Projections 5 and 6 as depicted in Fig. 4 are convenient embodiments. It has been found that housings with cross sections having a plane of symmetry are easily held and ergonomically pleasing. It is preferred that housings having such shapes be used herein. It is preferred that the housing and the container be of a reusable type, and the design should therefore facilitate easy reuse, refilling, and cleaning. It is also preferable that the container be shaped and balanced such that it remains standing upright when placed on a flat surface.
The housing typically contains a mouth for adding the conditioning composition and water. For convenient use, the mouth should be of sufficient width, such as depicted as 7 in Fig. 3.
Referring to Fig. 3, the dispensing passage 2 allows the user to dispense the treated water in the housing toward the distal end 3 where the applicator 4 is attached. The dispensing passage 2 may have the structure of a neck to allow a suitable angle to the applicator. The applicator 4 allows the user to apply the treated water directly onto the hair or scalp. The applicator has a design suitable for working through the hair, such as a comb or a brush. Preferred is a brush having bristles having an area comparable to hair brushes. An applicator so designed may providing effective rinsing benefits, as well as additional detangling and scalp massage benefits. Still preferred is an applicator so structured that relatively equal flow of treated water is provided by the bristles. In one preferred embodiment as depicted in Fig. 3, the applicator has a channel 41 directly beneath the base of the bristles 42, the channel being in communication with the dispensing passage. The channel 41 delivers the treated water to a plurality of projections, one being 43. By arranging the projections so that they are more or less equally distributed, as depicted in Fig. 4, a relatively equal flow of treated water is provided to the entire area of the applicator, thereby, to the hair. The applicator can be made of any applicable material, such as plastics, rubber, and combinations thereof. Preferred materials for the applicator include polyethylene, polypropylene, plastics, and combinations thereof.
Other possible variations, functions, and method of manufacturing of the hand held container are disclosed in detail in WO 98/16438 and WO 99/07272, both assigned to The Procter & Gamble Company.
