Description

DEODORANT COMPOSITIONS IN GEL THAT HAVE ^ REDUCED LEVEL OF SKIN IRRITATION FIELD OF THE INVENTION The present invention relates to gel deodorizing compositions that provide a reduced degree of skin irritation. In particular, the present invention relates to deodorant gel compositions containing a gelling agent, deodorant active or fragrance, and a select combination of a polymeric alcohol and non-polymeric alcohols.

BACKGROUND OF THE INVENTION __ Topical deodorants have been formulated in a variety of forms and are intended for topical application on human skin to mask or prevent odors associated with human perspiration.These topical deodorants are usually applied topically To the armpit or other area of the skin in the form of soft deodorant gels or sticks.These product forms usually contain a gelling agent, solvent and perfume or an antimicrobial active.

Fatty acid soaps are commonly used as gelling agents in topical deodorant gels, examples of which include sodium or potassium salts of naturally occurring fatty acids. In general, the gelling agent is used in combination with a highly polar alcohol solvent to provide aesthetic properties such as, for example, clarity, ease of application, moderately cold and cool feel in the application, lack of dusty residue, and dry feeling. Monohydric and dihydric alcohols, especially propylene glycol and dipropylene glycol, are often used for this purpose. Many types of gel deodorizing formulations are known, including those comprising fatty acid salts and a solvent such as, for example, water, monohydric alcohols, or dihydric alcohols. A typical example of this formulation are alcohol-containing gels comprising a fatty acid salt or other similar gelling agent, triclosan or other deodorant active and a polar solvent such as, for example, ethanol, propylene glycol, dipropylene glycol or other higher molecular weight polypropylene glycols. . Although these deodorant gels containing alcohol are very popular and are commonly used, many of them are also very strong for the skin and can cause excessive skin irritation after topical application. Therefore, it is an object of the present invention to provide a deodorant gel composition containing alcohol that is mild to the skin and causes minimal or no irritation therein, and furthermore provide a composition containing a select proportion of an alcohol. polymeric and non-polymeric alcohols. A further object of the present invention is to provide a composition having a dry feel and other improved cosmetic benefits such as, for example, ease of application, emolliency, fragrance durability and / or reduced level of visible residue.

BRIEF DESCRIPTION OF THE INVENTION The present invention is directed to gel deodorant compositions comprising from about (a) 0.001% to about 50% by weight of a deodorant active, fragrance, or combination thereof; (b) from about 0.01% to about 20% by weight of a gellant; (c) from about 5% to about 90% by weight of a polymeric alcohol having at least one free hydroxyl group and also having from about 2 to about 80 alkoxylated radicals, each having from about 2 to about 6 carbon atoms; carbon; (d) from about 5% to about 90% by weight of a non-polymeric alcohol having at least two free hydroxyl groups and also having from about 3 to about 20 carbon atoms, wherein the weight ratio of the polymeric alcohol to non-polymeric alcohol is from about 18: 1 to about 1: 5; (e) from zero percent to about 10% by weight of glycerin; and (f) from approximately 0.01% to approximately! 89% by weight ~ of water. It has been found that the deodorant gel compositions of the present invention are gentle to the skin and are associated with minimal or no irritation thereof. These compositions also remain substantially clear or translucent for long periods of time and provide improved cosmetic benefits such as for example dry feel, ease of application, emolliency, deodorant efficacy, fragrance durability and / or no dusty residue.

DETAILED DESCRIPTION OF THE INVENTION The gel deodorant compositions of the present invention comprise as essential ingredients a gelling agent, a polymeric alcohol, a non-polymeric alcohol and a perfume and / or deodorant active. These gel deodorant compositions are intended for topical application in the armpit or other suitable areas of the skin. Preferably, the gel deodorizing compositions are in the form of solid solid or soft bars, but may also be formulated in a variety of non-stick formulations suitable for application to the armpit or other area of the skin. The term "environmental conditions" in the sense in which it is used herein refers to the surrounding conditions under about one (1) atmosphere of pressure, at about 50% relative humidity, and at about 25 ° C. The gel deodorant compositions of the present invention may comprise, consist of, or consist essentially of essential elements and limitations of the invention described herein, as well as also any other additional or optional ingredients, components, or limitations described in I presented. - All percentages, parts and proportions are by weight of the total composition, unless otherwise specified.

These active deodorants and perfumes include any deodorant or fragrance known or otherwise safe and effective for topical application to human skin. i Unless otherwise specified, the term "active" in the sense in which it is used herein generally refers to deodorant active or fragrances, while the term "deodorant active" specifically refers to materials topics that can avoid or eliminate bad smells that result in perspiration. The term "fragrance" in the sense in which it is used herein, specifically refers to any topical material that covers or masks odors that result from perspiration, or that otherwise gives the composition the aroma ^ of desired perfume. a) Active Deodorant. Deodorant actives suitable for use in the gel deodorant composition include any topical material that is known or otherwise effective in preventing or eliminating odors associated with perspiration.

Each of the exemplified compositions are prepared by combining all the components listed, except for the gellant and the fragrance where applicable, and heating with agitation the combination of the ingredients at a temperature above the melting point of the gellant but less than 1 í 0 ° C. The gelling agent is then added while continuing the heating and stirring of the mixture until it results in a clear single phase solution, at which point the mixture is cooled to a temperature of between 69 ° C and 80 ° C. . The fragrance is added with agitation to the cooled mixture. The mixture containing the fragrance is then emptied into an appropriate distributor or other container and allowed to solidify by cooling to room temperature.

The compositions described in Examples I-VI were also formulated with 0.25% triclocarban instead of 0.3% triclosan. Approximately 0.05% by weight of water was also added to the triclocarbano formulations.
