Description

ANTI-DAMPING SHAMPOO AND CONDITIONERS CONTAINING POLYALYKENGLYCOLES AND CATIÓN POLYMERS TECHNICAL FIELD OF THE INVENTION The present invention relates to shampoo compositions that provide a superior combination of anti-dandruff efficacy and conditioning. These compositions contain anionic surfactants, conditioning agents, antidandruff particulates, cationic polymers, polyalkylene glycols and water.

BACKGROUND OF THE INVENTION Shampoo compositions comprising various combinations of detergent surfactants and conditioning agents, especially silicone conditioning agents, are known in the art and are commercially available. It has been found that many of these compositions provide excellent cleaning and conditioning performance for the hair. For example, Shampoo Plus Conditioner with Pro-Vitamin-in-One of Pantene® containing anionic surfactants, a cationic polymer and silicone conditioning agents provide excellent benefits of cleaning, conditioning and hair feel at the time of application to the hair Anti-dandruff shampoos are also well known in the art and are also commercially available. Anti-dandruff shampoos usually incorporate an anti-dandruff active agent and detergent surfactants. Among the preferred types of antidandruff agents are crystalline, particulate anti-dandruff agents, such as, for example, sulfur, selenium disulfide and heavy metal salts of pyridinethione. Soluble antidandruff agents, such as, for example, ketoconazole are also known in the art. Anti-dandruff shampoos that also provide conditioning benefits are also known in the art. For example, U.S. Patent No. 5,624,666 exemplifies and claims shampoo compositions containing anionic surfactants, cationic polymers and zinc pyridinethione as an antidandruff agent. U.S. Patent No. 5,624,666 shows that conditioning agents, such as, for example, silicone fluids, can optionally be incorporated into the compositions herein. Anti-Dandruff Shampoo Head & Shoulders® plus conditioner is an example of a commercialized product that provides anti-dandruff and conditioning benefits at the time of shampooing hair. However, some consumers want a shampoo that provides a superior combination of anti-dandruff efficacy and conditioning performance against currently marketed products. This superior combination of efficiency and conditioning can be difficult to achieve. For example, it was previously believed that excellent anti-dandruff efficacy could be achieved by using a coacervate to deposit the antidandruff active agents on the hair and scalp. Unfortunately, the use of the most efficient coacervates to deposit the antidandruff actives on the hair or scalp can adversely affect the conditioning, specifically the sensation of cleansing the hair. In order to achieve good conditioning, the level of the anti-dandruff agent could be reduced, resulting in good conditioning, although with an anti-dandruff efficacy less than optimum.

However, applicants have now discovered that surprisingly, the bioavailability and scope of the anti-dandruff active agent are much more predictable for efficacy than the deposition of the active agent on the hair or scalp. In fact, the applicants have found that, in some cases, even when an active antidandruff deposited very well on the hair and scalp, an acceptable anti-dandruff efficacy has not been achieved. On the contrary, a good anti-dandruff efficacy could be achieved in situations where the active anti-dandruff agent has a good reach and was quite bioavailable, although it was not deposited superiorly on the hair or scalp. Thus, for a shampoo composition to provide a superior combination of anti-dandruff efficacy and conditioning compared to known shampoo compositions, it must meet certain criteria with "respect to bioavailability and scope, although it does not necessarily have to have the ability to deposit the active agent. Anti-Dandruff Superiorly on the Hair or Scalp One object of the present invention is to provide shampoo compositions having a superior combination of anti-dandruff efficacy and conditioning.An objective of the present invention is also to provide a method for cleaning and conditioning hair These and other objectives will be more readily apparent from the following detailed description.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to shampoo compositions that provide a superior combination of anti-dandruff efficacy and conditioning. These shampoo compositions comprise: (A) between about 5% and 50% by weight, of an anionic surfactant; (B) between about 0.01% and 10% by weight, of a non-volatile conditioning agent; (C) between about 0.1% and 4% by weight, of an antidandruff particulate; (D) between about 0.02% and 5% by weight of the composition of at least one cationic polymer; (E) between about 0.005% and 1.5% by weight of a polyalkylene glycol; and (F) water.

When silicones with high refractive index are used in the anti-dandruff and conditioning shampoo compositions of the present invention, they are preferably used with an extension agent, such as a silicone resin or a surfactant, to reduce the surface tension in a sufficient amount to improve the extension and, thus, improve the luster (after drying) of the hair treated with the composition. In general, an amount of the extension agent is used which is sufficient to reduce the surface tension of the high refractive index polysiloxane fluid by at least about 5%, preferably at least about 10%, most preferably at least about 15% even more preferably at least about 20%, with the highest preference, of at least about 25%.

Thus, it is contemplated that proportions significantly greater than 1000: 1 may be used. Suitable silicone fluids for use in the anti-dandruff and conditioning shampoo compositions of the present invention are set forth in U.S. Patent No. 2,826,551, U.S. Patent No. 3,964,500, U.S. Pat. No. 4,364,837, British Patent 849,433 and Si li with Compounds, Petrarch Systems, Inc. (1984), all of which are incorporated herein by reference. v. Silicone resins Silicone resins may be included in the silicone conditioning agent. These resins are highly crosslinked polymeric siloxane systems. 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 clear to one of ordinary skill 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 that are incorporated in the silicone resin. In general, silicone materials having a sufficient level of trifunctional and tetrafunctional siloxane monomer units (and, therefore, a sufficient level of crosslinking) so that they dry to form a rigid or hard film, are considered as resins of sylicon. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone resins suitable for use in the anti-dandruff and conditioning shampoo compositions of the present invention will generally have at least about 1.1 oxygen atoms for each silicon atom. Preferably, the ratio between oxygen atoms: silicon is at least about 1.2: 1.0. Silanes in the manufacture of silicone resins include, but are not limited to: monomethyl-, dimethyl-, trimethyl-, mono-phenyl-, diphenyl-, methylphenyl-, monovinyl- and met-vinyl-chlorosilanes and tetrachlorosi-lane, where the silanes met ilsubstituted are the most commonly used.

Commercially available silicone resins will generally be supplied in a form dissolved in a volatile or non-volatile, low viscosity silicone fluid. The silicone resins for use herein should be supplied and incorporated into the compositions herein in dissolved form, as will be readily apparent to those of skill in the art. Silicone materials and silicone resins, in particular, 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 silicone 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) 3SiO0.5; D denotes the difunctional unit (CH3) 2SiO; T denotes the trifunctional unit (CH3) SiO? .5; and Q denotes the quadri or tetrafunctional unit Si02. The prime signs in the unit symbols (for example, M ', D1, T' and Q ') denote substituents other than methyl and must be specifically defined each time they are present. Typical alternating 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 that indicate the total number of each type of units in the silicone (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. The high relative molar amounts of T, Q, T 'and / or Q' relative to D, D 'M and / or M' in a silicone resin are indicative of high levels of crosslinking. However, as discussed above, the general level of crosslinking can also be indicated by the oxygen to silicon ratio. Suitable silicone resins for use in the anti-dandruff and conditioning shampoo compositions of the present invention include, but are not limited to: MQ, MT, MTQ, MQ and MDTQ resins. The preferred silicone substituent is methyl.

Cationic polymer The anti-dandruff and conditioning shampoo compositions of the present invention comprise between about 0.02% and 5% by weight of the composition, preferably between about 0.05% and 3%, most preferably between about 0.1% and 2%, most preferably between about 0.5% and 1%, of at least one polymer for cationic deposition and conditioning, organic, suitable for application to hair or skin. It is believed that cationic polymers provide an anti-dandruff efficacy and enhanced conditioning for the shampoo compositions described herein. These cationic polymers must be physically and chemically compatible with the essential components described herein and should not otherwise unduly damage the stability, aesthetics or performance of the product. 1. Characteristics of the cationic polymers The cationic polymers useful in the present invention should be selected and should be present at a level such that the cationic polymers are soluble in the shampoo composition and that they are preferably soluble in a complex coacervate phase in the composition of shampoo, at the time of dilution. This coacervate is described in detail later. The physical properties of the cationic polymers and suitable counterions are also detailed. i. Coacervate formed from the cationic polymer At the time of dilution of the shampoo composition, a coacervate is formed between the cationic polymer and the anionic detergent surfactant component (described above) of the present invention. It is believed that the cationic entity of the polymers binds with the cationic entity of the surfactant to form an insoluble complex that precipitates at the time of dilution (the coacervate). Complex coacervates of the cationic polymer can also be formed with other optional anionic components of the shampoo composition (described below). The formation of the coacervate depends on a variety of criteria, such as, for example, molecular weight, concentration of the component and proportion of the ionic interacting components, ionic strength (which includes the modification of the ionic strength, for example, by the addition of salts ), charge density of cationic and anionic components, pH and temperature. Coacervate systems and the effect of these parameters have been described, for example, in J. Caelles, et al., "Anionic and Cationic Compounds in Mixed Systems", Cosme ti cs & Toile tri es, vol. 106, (April 1991), pp. 49-54; C. J. van Oss, "Coacervat ion, Complex-Coacervat ion and Flocculation ", J. Dispersion Science and Tech., Vol.9 (5.6), (1988-89), pp. 561-73, and in DJ Burgess," Practical Analysis of Complex Coacervate Systems ", J. of Coll Oid and Infa ce Sci in CE, Vol 140, No. 1, (November 1990), pp 227-38, all descriptions are incorporated herein by reference The shampoo compositions described herein, usually have a proportion of an anionic detergent surfactant component for the cationic polymer component of between about 25: 0.02 and 1: 5, preferably between about 20: 0.1 and 12: 1. It is believed that coacervates provide conditioning benefits, in special conditioning benefits during the use of the product when the hair is wet, by helping to deposit the conditioning agents on the hair and scalp It is also known in the art that coacervates aid in the deposition of other types of particulates. It is known that this it occurs when concentrating the particulates within the limits of the coacervate at the time of dilution. It has also been found that the characteristics of the polymer in these compositions can affect the bioavailability / range of the antidandruff particulates, these characteristics include molecular weight and charge density of the cationic guar polymer. Guar with low molecular weight are preferred, guar with low charge density are preferred. Guar with low molecular weight and low charge density are quite preferred. It is believed that these select guars impart modified physical properties (ie, rheology) to the formed coacervates. The techniques for analyzing the formation of complex coacervates are known in this field. For example, microscopic analyzes of the shampoo compositions, at any selected dilution step, can be used to identify a coacervate phase has been formed. This coacervate phase can be identified as an additional emulsified phase in the composition. The use of dyes can be used to distinguish the coacervate phase from other insoluble phases dispersed in the shampoo composition. ii. Physical Properties of the Cationic Polymer The average molecular weight of cationic conditioning polymers suitable for use herein is typically between about 5,000 and 10,000,000, preferably between about 100,000 and 2,000,000, more preferably between about 200,000 and 1, 500, 000, more preferably between about 250,000 and 850,000, more preferably between about 350,000 and 850,000, with the highest preference of between about 350,000 and 500,000. The polymers have a cationic charge density typically between about 0.2 meq / g and 7 meq / g, as measured at the pH of the intended use of the shampoo composition, preferably between about 0.4meq / gm and 5meq / g, of greater preference of between about 0.6meq / g and 2 meq / g, more preferably between about 0.5meq / g and O.lmeq / g, most preferably between about 0.5meq / g and 0.9meq / g. The pH of the intended use of the shampoo composition normally ranges from about pH 3 to pH 9, preferably from about pH 4 to pH 7. iii. Counterions used to form the cationic polymer Any anionic counterions can be used together with the cationic polymers with the proviso that the cationic polymers remain soluble in water, in the shampoo composition, or in a coacervate phase of the shampoo composition and with the condition that the counterions be physically and chemically compatible with the essential components of the shampoo composition or otherwise not unduly impair the performance, stability or aesthetics of the product.

A suitable method for preparing the anti-dandruff and conditioning shampoo compositions described in the following Examples I-XV (below): about one-third of all is added to the ammonium laureth sulfate (added as 25% by weight solution) to a deposit for jacketed and heated mixture between about 60 ° C and 80 ° C with slow stirring to form a surfactant solution. Cocamide MEA and fatty alcohols are added (where appropriate) to the tank and dispersed. Salts (eg, sodium chloride) and pH modifiers (eg, citric 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, the preservative is added to the surfactant solution. The resulting mixture is cooled to between about 25 ° C and 40 ° C and collected in a finishing tank. As a result of this cooling step, the EGDS crystallizes to form a crystalline lattice in the product. The rest of the ammonium laureth sulfate and other components, including silicone and antidandruff particulate, are added to the tank to finish with agitation to ensure homogeneous mixing. The cationic polymer is dispersed in water as an aqueous solution of between about 0.1% and 10% and then added to the final mixture. Once all the components have been added, the viscosity and pH modifiers can be added, as necessary, to the mixture to adjust the viscosity and pH of the product to the desired degree.
