Description

COMPOSITION OF ANTISTATIC SHAMPOO This invention relates to shampoo compositions and the use of components of the compositions. It is widely believed that Malassezia yeasts, such as Malassezia fúrfur, are the main cause of dandruff. The main intervention strategy, if not the only one, currently used in the market for the treatment of dandruff is the topical application of antifungals, such as zinc pyrithione (ZnPTO), climbazole, octopirox and ketoconazole, which are normally delivered from a shampoo. These antifungal agents remove (or at least reduce the level of) the Malassezia of the scalp and provide effective treatment of the anti-dandruff condition. Certain compositions used in the treatment of dandruff are perceived as harsher for the hair, leaving the treated hair dry, rough and difficult to comb. CA 2078375 describes a shampoo composition for the treatment of headaches and pain comprising specific amounts of natural anti-pain and headache oils, as well as beeswax and silicone oil. There is no mention of anti-dandruff agents in CA 2078375 or disclosure regarding the function of beeswax or silicone oil. EP 0502616 describes a mild cosmetic composition comprising an alkylpolyglycoside surfactant, a wax and optionally one or more thickening agents, wherein the composition has a specified viscosity. The wax can be beeswax. However, EP 0502616 does not disclose any anti-dandruff composition or composition comprising silicones. EP 041341 7 describes a conditioning shampoo for hair comprising a specified anionic detergent, a water-insoluble hair conditioning aid, such as silicones, polyethylenes, paraffins, isoparaffins, petrolatums, microcrystalline waxes, C 8 -36 fatty acids (mixed) and / or triglycerides, stearyl stearate and beeswax, a stabilizer and an aqueous medium. It is stated that the improvement in hair conditioning is due to the inclusion of the specified anionic detergent. EP 0471606 discloses liquid and stabilized skin and fiber compositions which have improved high temperature stability due to the inclusion of stabilizing agent, which is a long chain alcohol or suitable derivative thereof. The compositions further comprise a liquid medium, an emulsifying agent and a skin or fiber treatment material that is insoluble in the liquid medium. Examples of the skin treatment material include: petrolatum paraffin waxes; isoparaffins; mineral oils; microcrystalline waxes; bee waxes; organosilicon compounds, including silicones and aminosilicones; polyethylenes; triglycerides of C1 8 -36; perfumes; sunscreen agents and anti-dandruff agents. In particular, EP 0471606 discloses anti-dandruff compositions comprising specified amounts of an anionic detergent, an anti-dandruff agent insoluble in water, a long chain alcohol and water.

There is still a need for effective shampoo compositions for treating dandruff, which can deliver improved foam quality and which can leave treated hair with improved conditioning properties such as, for example, softer feel, larger body and better combability dry without compromising the effectiveness of the treatment for dandruff. Also, there is a need for shampoo compositions having improved softness and / or improved foam quality and / or smoothness and / or conditioning benefits. According to a first aspect of the present invention, there is provided a shampoo composition comprising: an antidandruff agent in an amount from 0.01% to 10% by weight; beeswax in an amount from 0.01% to 10% by weight; and a silicone in an amount from 0.01% to 10% by weight. In a further aspect of the present invention, there is provided the use of a combination of beeswax and silicone in a shampoo composition to provide one or more selected properties of increased softness, improved foam quality, improved conditioning and improved hair handling benefits. By the term "improved" is meant that the properties of shampoo compositions comprising a combination of beeswax and silicone according to the invention, are superior to shampoo compositions which do not contain the combination of beeswax and silicone. In still a further aspect of the present invention, there is provided the use of beeswax and silicone in a composition of anti-dandruff shampoo to provide improved foam properties and effective deposition of an anti-dandruff agent. The present invention relates in part to the surprising finding that a combination of beeswax and a silicone in a shampoo composition can lead to unexpected improvement in such properties as, for example, softness, foam quality, conditioning and benefits of manageability of hair, such as smoothness, ease of combing, reduced hair volume and the like. In particular, the compositions of the present invention can provide shampoos that are soft and still produce foams that possess properties such as unexpected creaminess. It is known that mild shampoo compositions usually produce foams that have a lower sense of quality and appearance and as a result soft shampoos may be less attractive to the consumer. Without wishing to be bound by a theory, it is believed that there is a synergistic interaction between beeswax and silicon that can lead to the improved hair handling benefits of the present compositions. Additionally, the present invention relates in part to the finding that silicone and beeswax may not interfere with the deposition of anti-dandruff agents of anti-dandruff shampoo compositions in which they are both included and may therefore provide Anti-dandruff compositions having, for example, improved foam properties. The anti-dandruff agent can suitably be any anti-dandruff agent known to the person skilled in the art who is capable of treating and / or prevent the formation of dandruff. In particular, the anti-dandruff agent can be any antimicrobial agent that is suitable for the treatment and / or prevention of dandruff.

In a particularly preferred embodiment, the anti-dandruff agent is climbazole. The compositions of the invention include beeswax. The beeswax can vary in color from white to yellow through coffee to black depending on the type of pollen carried by the bees that produce it. Any of these forms may be suitable for the present invention. By the term "beeswax" it is intended to include natural beeswax of combs either in an unpurified or preferably purified state and synthetic beeswax and substitute, as well as beeswax which has been modified, for example, organically modified. The term "synthetic and substitute" beeswax includes substances that have properties similar to those of naphural beeswax.

In a particularly preferred embodiment, the weight ratio of beeswax to silicone is about 2: 1. Various methods for making emulsions of silicone particles for use in the invention are available and well understood and documented in the art. For example, emulsions can be prepared by high-mechanical mechanical mixing of silicone and water, or by emulsifying the silicone with water and an emulsifier (by mixing the silicone in a heated solution of the emulsifier, for example), or by a combination of emulsification. Mechanics and chemistry A proper technique additional for the preparation of emulsions of silicone particles is the emulsion polymerization. Polymerized emulsion silicones as such are described in U.S. Pat. 2,891, 820 (Hyde), U.S. Patent No. 3,294,725 (Findlay) and U.S. Patent No. 3,360,491 (Axon). The viscosity of the silicone itself (not the emulsion or the final shampoo composition) preferably ranges from 10,000 cps to 5 million cps. The viscosity can be measured by means of a glass capillary viscometer as further disclosed in Dow Corning Corporate Test Method CTM004 (Dow Corning Corporate Test Method), July 20 1970. Suitable silicones include polydiorganosiloxanes, in particular polydimethylsiloxanes having the CTFA dimethicone designation.

Apparatus 1. Canetail tips of 6.67 g / 25 cm (3 for each composition) made from moored Yugoslav red hair. 2. Horizontal bar with safety locks to suspend the ends of the hair. 3. Trial matrix. 4. Panel of advisers. 5. Plastic comb (8 teeth / cm, 0.025 cm tooth width).

Operator deviation The test should be conducted with double ciedgo to avoid the possibility that the test operator (person conducting the test) influences the decision of the assessor (person who judges the different products).

Procedure 1. Before performing the test, the tail tips are balanced to ensure that there are no "blush" tips in the assembly.

Wash each tip of the glue with 2 x 0.5 ml SLES 2EO at 16% and let it dry, either in a oven set at 50 ° C for 1 hour or at room temperature overnight. . According to the test matrix, suspend the tail ends in pairs from the horizontal bar (first tail tip on the left). 3. Ask the panelist to close his eyes and "narrow" the tip of the tail between the index and middle fingers of the hand with which he does not write and pass down each tail tip in turn. Then ask the assessor to judge which of the tail ends feels softer. A "no difference" judgment is not allowed. 4. The results are analyzed using the VITRO computer program. 5. If no significant differences are found between the set of 3 tail tips, then proceed to 6. If significant differences are found, identify the tail tip (s) of "rouge". Repeat the balancing procedures with a second wash with 2 x 0.5 ml of SLES 2EO at 16%. If differences are found again, then new tail ends are required. 6. Treat the acrylic tail tips with the compositions of the invention and the comparative compositions and repeat steps 2 through 4.
