Description: ANTI-DANDRUFF 4ND CONDITIONING SHAMPOOS CONTAINING POLYALKYLENE GLYCOLS AND CATIONIC POLYMERS TECHNICAL FIELD OF THE INVENTION The present invention relates to shampoo compositions which provide a supenor combination of anti-dandruff efficacy and conditioning These compositions contain anionic surfactants, conditioning agents, anti-dandruff particulates, catiomc polymers, polyalkylene glycols, and water BACKGROUND OF THE INVENTION Shampoo compositions comprising vanous combmations of detersive surfactants and conditioning agents, especially sihcone conditioning agents, are known m the art and are commercially available Many of these compositions have been found to provide excellent hair cleansmg and conditioning performance For example, Pantene® Shampoo Plus Pro- Vitamin Conditioner-in-One formulas which contam anionic surfactants, a catiomc polymer and sihcone conditioning agents provide excellent cleaning, conditioning and hair feel benefits upon application to hair Anti-dandruff shampoos are also well known in the art and are also commercially available Anti- dandruff shampoos typically incorporate an anti-dandruff active and detersive surfactants Among the preferred type of anti-dandruff agents are particulate, crystallme anti-dandruff agents, such as sulfur, selemum disulfide and heavy metal salts of pyndinethione Soluble anti-dandruff agents, such as ketoconazole, are also known in the art Anti-dandruff shampoos which also provide conditioning benefits are likewise known in the art For example, U S Pat No 5,624,666 exemplifies and claims shampoo compositions which contam anionic surfactants, catiomc polymers and zmc pyndinethione as an anti-dandruff agent U S Pat No 5,624,666 teaches that conditioning agents such as sihcone fluids can optionally be incorporated into the compositions therein Head & Shoulders® -Dandruff Shampoo Plus Conditioner is an example of a marketed product which provides both anti-dandruff and conditionmg benefits upon application of the shampoo to hair Nevertheless, some consumers desire a shampoo which provides a supenor combmation of anti- dandruff efficacy and conditionmg performance versus currently marketed products Such a supenor combmation of efficacy and conditioning can be difficult to achieve For example, it was previously believed that excellent anti-dandruff efficacy could be achieved by utilizing a coacervate to deposit anti-dandruff actives on the hair and scalp Unfortunately, the use of coacervates to deposit anti-dandruff actives on the hair or scalp can negatively affect conditioning, specifically clean hair feel In order to achieve good conditioning, the level of anti-dandruff agent could be reduced, resultmg in good conditionmg, but less than optimal anti-dandruff efficacy Applicants have now discovered, however, that, surprisingly, bioavailabi ty and coverage of the anti-dandruff active are much more predictive of efficacy than deposition of the active on the hair or scalp In fact, Applicants have found that, in some cases, even when an anti-dandruff active deposited very well on the hair and scalp acceptable anti-dandruff efficacy was not achieved Conversely, good anti-dandruff efficacy could be achieved in situations where the anti-dandruff active had good coverage and was highly bioavailable, but did not deposit superiorly to the hair or scalp Thus, in order for a shampoo composition to provide a superior combination of anti-dandruff efficacy and conditioning compared to known shampoo compositions, it must meet certam criteria with respect to bioavailability and coverage, but it does not necessarily have to have the ability to deposit the anti-dandruff active superiorly on the hair or scalp It is an object of the present invention to provide shampoo compositions, which provide a supenor combmation of anti-dandruff efficacy and conditionmg It is also an object of the present mvention to provide a method for cleansmg and conditionmg the hair These, and other objects, will become readily apparent from the detailed description below SUMMARY OF THE INVENTION The present invention relates to shampoo compositions which

Silicone resins Sihcone resms may be included m the sihcone conditiomng agent of the anti-dandruff and conditionmg shampoo compositions of the present mvention These resms are highly cross-linked polymenc siloxane systems The cross-linking is introduced through the incorporation of tπfunctional and tetrafunctional silanes with mono-functional or difunctional, or both, silanes durmg manufacture of the sihcone resm As is apparent to one of ordinary skill m the art, the degree of cross-linkmg that is required m order to result in a sihcone resm will vary accordmg to the specific silane units incorporated mto the sihcone resm Generally, sihcone matenals which have a sufficient level of tπfunctional and tetrafunctional siloxane monomer units (and hence, a sufficient level of cross-linking) such that they dry down to a rigid, or hard, film are considered to be sihcone resins The ratio of oxygen atoms to silicon atoms is indicative of the level of cross-linking in a particular sihcone matenal Sihcone resins suitable for use in the anti-dandruff and conditionmg shampoo compositions of the present mvention generally have 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 m the manufacture of sihcone resms mclude, but are not limited to monomethyl-, dimethyl-, tπmethyl-, monophenyl-, diphenyl-, methylphenyl-, monovmyl-, and methylvmyl-chlorosilanes, and tetra- chlorosilane, with the methyl-substituted silanes bemg most commonly utilized Preferred resms are available from General Electnc as GE SS4230 and GE SS4267 Commercially available si cone resms are generally supplied in a dissolved form m a low viscosity volatile or non-volatile sihcone fluid The sihcone resms for use herem should be supplied and incorporated mto the present compositions m such dissolved form, as will be readily apparent to one of ordinary skill in the art Sihcone mateπals and sihcone resms in particular, can convemently be identified accordmg to a shorthand nomenclature system known to those of ordinary skill m the art as "MDTQ" nomenclature Under 14 this system, the sihcone is descπbed according to presence of various siloxane monomer units which make up the sihcone. Briefly, the symbol M denotes the monofunctional unit (CH 3 ) 3 SιO 0 s; D denotes the difunctional unit (CH 3 ) 2 SιO; T denotes the tπfunctional unit (CH 3 )SιOι 5 , and Q denotes the quadra- or tetra-fϊinctional unit Sι0 2 .

Coacervate formed from cationic polymer A coacervate is formed, upon dilution of the shampoo composition, between the catiomc polymer and the amomc detersive surfactant component (described above) of the present invention It is believed that the catiomc moiety of the polymer binds with the amomc moiety of the surfactant to form an insoluble complex that precipitates, upon dilution (the coacervate) Complex coacervates of the cationic polymer can also be formed with other optional amomc components of the shampoo composition (descπbed below) Coacervate formation is dependent upon a vanety of criteπa, such as molecular weight, component concentration, and ratio of interactmg ionic components, ionic strength (including modification of ionic strength, for example, by addition of salts), charge density of the catiomc and amomc components, pH, and temperature Coacervate systems and the effect of these parameters have been described, for example, in J Caelles, et al , "Amomc and Catiomc Compounds in Mixed Systems", Cosmetics & Toiletries, vol 106, (April 1991), pp 49-54, C J van Oss, "Coacervation, Complex-Coacervation and Flocculation", J Dispersion Science and Tech , vol 9 (5,6), (1988-89), pp 561-73, and m D J Burgess, "Practical Analysis of Complex Coacervate Systems", J of Colloid and Interface Science, vol 140, no 1, (November 1990), pp 227-38, all of which descnptions are incorporated herem by reference The shampoo compositions descπbed herein, typically have a ratio of amomc detersive surfactant component to catiomc polymer component from about 25 0 02 to about 1 5, preferably from about 20 0 1 to about 12 1 Coacervates are believed to provide conditionmg benefits, especially conditionmg benefits duπng product use when the hair is wet, by helpmg to deposit conditioning agents onto the hair and scalp Coacervates are also known m the art to aid deposition of other types of particulates This is thought to occur by concentrating particulates within coacervate boundanes upon dilution It has also been found that the charactenstics of polymer m such compositions can affect the bioavailabihty/coverage of anti-dandruff particulates, such characteπstics include cationic guar polymer molecular weight and charge density Guars with lower molecular weight are prefeπed, guars with lower charge density are prefeπed Guars with lower molecular weight and lower charge density are highly prefeπed It is believed that these select guars impart modified physical properties (l e rheology) to the coacervates formed Techniques for analysis of formation of complex coacervates are known in the art For example, microscopic analyses of the shampoo compositions, at any chosen stage of dilution, can be utilized to identify whether a coacervate phase has formed Such coacervate phase will be identifiable as an additional emulsified phase m the composition The use of dyes can aid in distinguishing the coacervate phase from other insoluble phases dispersed m the shampoo composition ii.

A method such as that described m U.S. Pat. No. 5,837,661, which descnption is incorporated herein by reference, could be employed, wherem the anti-dandruff particulate of the present invention would typically be added m the same step as the sihcone premix is added m the '661 descnption. IV. Methods of Use The anti-dandruff and conditionmg shampoo compositions of the present mvention are used m a conventional manner for cleansing and conditionmg the hair or skin. They are particularly used m a conventional manner for treatmg the condition commonly known as dandruff. An effective amount of the composition for cleansmg and conditionmg the hair or skin is applied to hair, or other region of the body, that has preferably been wetted, generally with water, and then the composition is rmsed off. Effective amounts typically range from about lg to about 50g, preferably from about lg to about 20g. Application to the hair typically mcludes working the composition through the hair such that most or all of the hair is contacted with the composition. This method for providmg anti-dandruff efficacy and conditiomng hair compnses the steps of: (a) wetting the hair with water, (b) applying an effective amount of the shampoo composition to the hair, and (c) nnsmg the shampoo composition from the hair usmg water These steps may be repeated as many times as desired to achieve the cleansmg, conditiomng, and anti-dandruff benefits sought. It is also contemplated that when the anti-dandruff particulate employed is zmc pyπthione, and/or if other optional hair growth regulatmg agents are employed, the shampoo compositions of the present mvention, may, provide for the regulation of growth of the hair. The method of regularly usmg such shampoo compositions compnses steps a, b, and c (above). EXAMPLES The following are non-limiting examples of the anti-dandruff and conditionmg shampoo compositions of the present mvention. The examples are given solely for the purpose of illustration and are not to be construed as limitations of the present mvention, as many vaπations thereof are possible without departing from the spirit artd scope of the mvention, which would be recognized by one of ordinary skill in 36 the art In the examples, all concentrations are listed as weight percent, unless otherwise specified As used herein, "minors" refers to those optional components such as preservatives, viscosity modifiers, pH modifiers, fragrances, foam boosters, and the like. As is apparent to one of ordinary skill in the art, the selection of these minors will vary depending on the physical and chemical characteristics of the paπicular ingredients selected to make the present invention as described herem A suitable method for preparing the anti-dandruff and conditiomng shampoo compositions described in Examples I - XV (below) follows About one-third to all of the ammonium laureth sulfate (added as 25wt% solution) is added to a jacketed mix tank and heated to about 60°C to about 80°C with slow agitation to form a surfactant solution. Cocamide MEA and fatty alcohols, (where applicable), are added to the tank and allowed to disperse. Salts (e.g. sodium chloride) and pH modifiers (e.g. citπc acid, sodium citrate) are added to the tank and allowed to disperse. Ethylene glycol distearate ("EGDS") is added to the mixing vessel and allowed to melt. After the EGDS is melted and dispersed, preservative is added to the surfactant solution. The resultmg mixture is cooled to about 25°C to about 40°C and collected m a finishing tank. As a result of this coolmg step, the EGDS crystallizes to form a crystallme network m the product. The remainder of the ammomum laureth sulfate and other components, mcludmg the sihcone and anti-dandruff particulate, are added to the finishing tank with agitation to ensure a homogeneous mixture Catiomc polymer is dispersed m water as an about 0.1 % to about 10% aqueous solution and then added to the final mix. Once all components have been added, additional viscosity and pH modifiers may be added, as needed, to the mixture to adjust product viscosity and pH to the extent desired.
