Abstract: A method for cleansing the skin and providing an increased fragrance benefit after rinsing the skin form the cleansing composition which comprises applying to the skin a composition having: (a) one or a mixture of surfactants in sufficient quantity to cleanse the skin; (b) a fragrance in sufficient quantities to provide an aroma; (c) a silicone, a hydrocarbonaceous component or mixture thereof in sufficient quantities to bring about an increased fragrance benefit, and rinsing off said composition.

Description: SKIN CLEANSING COMPOSITION PROVIDING ENHANCED PERFUMED DEPOSITION BACKGROUND OF THE INVENTION Fragrances have been employed in skin care compositions for hundreds of years. These fragrances have a number of uses. They provide a recognized aroma to the user of the composition or a person in close juxtaposition to that person. Fragrances mask the odor produced by bacteria growing on the skin. Fragrances can work as a solubilizing agent for other organic materials in the composition. However, not infrequently the effects of fragrances in skin care compositions, particularly those of the "rinse-off' type are short lived. Assuming they stay on the skin during the short contact time and are not washed off during the skin care process, their adherence to the skin may be weak and/or their detachment from the skin occurs at too quick a rate, thereby leaving no significant odor after a short period of time following πnse off. Therefore in order to provide an appropriate fragrance to the head space above the skin, there must be a proper combination of quantity of fragrance on the skin, adhesion to the skin and release from the skin over an appropriate time period. This combination will provide a "persistent" odor over a significant period of time. A new composition has been discovered which can provide these fragrance benefits. The composition is a rinse-off cleansing composition which provides an improvement in fragrance benefits. SUMMARY OF THE INVENTION In accordance with the invention, there is a method for cleansing the skin and providing an increased fragrance benefit after rinsing the skin from the cleansing composition which comprises, applying to the skin a composition having: a. one or a mixture of surfactants in sufficient quantity to cleanse skin; b. a fragrance in sufficient quantities to provide aroma c. a silicone or a hydrocarbonaceous component or mixtures thereof in sufficient quantities to bring about increased fragrance benefits and rinsing off said composition. DETAILED DESCRIPTION OF THE INVENTION By fragrance is meant any volatile perfume agent which provides an aroma to the final composition in which the fragrance residues. Examples of such materials are those boiling at temperatures below about 500°C. The highly volatile, low boiling, perfume ingredients typically have boiling points of about 250°C or lower. The moderately volatile perfume ingredients are those having boiling points of from about 250°C to about 300°C. The less volatile, high boiling, perfume ingredients are those having boiling points of about 300°C to about 500°C. Many of the perfume ingredients as discussed hereinafter along with their odor and/or flavor characters, and their physical and chemical properties, such as boiling point and molecular weights are given in "Perfume and Flavor Chemicals (Aroma Chemicals)," Steffen Arctander, published by the author, 1969, incorporated herein by reference. It is preferred that the personal cleansing products herein contain a fragrance having at least about 5% of its components, more preferably at least about 25%, and most preferably at least about 50% of the fragrance components as highly volatile perfume ingredients having a boiling point of 250°C or lower.

Some natural oils also contain large percentages of highly volatile perfume ingredients. For example, lavandin contains as major components: linalool; linalyl acetate; geraniol; and citronellol. Lemon oil and orange terpenes both contain about 95% of d limonene. Examples of moderately volatile perfume ingredients are: amyl cinnamic aldehyde, iso-amyl salicylate, beta-caryophyllene, cedrene, cinnamic alcohol, coumarin, dimethyl benzyl carbinyl acetate, ethyl vanillin, eugenol, iso-eugenol, flor acetate, heliotropine, 3-cis-hexenyl salicylate, hexyl salicylate, lilial (para tertiarybutyl-alpha-methyl hydrocinnamic aldehyde), gamma-methyl ionone, nerolidol, patchouli alcohol, phenyl hexanol, beta-selinene, trichloromethyl phenyl carbinyl acetate, triethyl citrate, vanillin, and veratraldehyde.

The preferred surfactant is an anionic surfactant such as soap, alkylisethionate such as sodium cocoylisethionate, a sulfonate, a sulfate (optionally ethoxylated) and the like. Mixtures of surfactants can be employed. There should be sufficient surfactant present to bring about a cleansing effect. The surfactant preferably anionic or mixtures thereof involving one or more from the other families of illustrated surfactants (amphoteric, nonionic and the like) with or without an additional anionic surfactant, can be present in the composition in various quantities. For example broad minimums of the surfactant can be present at 1, 2, 3, 4, 5, 10, 15 or 20 wt.% > of the compositions, particularly where the aqueous composition is a liquid. With respect to liquid, aqueous, compositions, the anionic surfactant is from about 2 to about 25 wt.% of the composition, specifically about 5 to about 20 wt.%. Other surfactants may be present such as an amphoteric, particularly a betaine, and a nonionic, particularly an alkylated polyglycoside. Their quantities are from about 1 to about 20 wt.% of the composition. Generally the total surfactant in a liquid composition is at least about 3 or 4 wt.%>, preferably at least about 5 wt.% and is generally no more than about 30 wt.%>, preferably no more than about 25 wt.% but can be as low as more than about 10, 15 or 20 wt.%>. For a solid composition, the total surfactant can be from about 60 to about 90 wt.%>, preferably from about 70 to about 85 wt.%, of the composition. Soap can be present at about 15 to about 100 wt.%) of the total surfactant. "Soap-bars" generally have from about 65 to about 90 wt.%) soap therein with less than about 10 wt.%>, preferably less than about 5 wt.%> of other surfactant therein. Most preferably, there is zero or zero to about 2 wt.% > of other surfactant therein Bars having a smaller quantity of soap within the disclosed range of soap usually have a mild synthetic surfactant therein such as sodium cocoyl isethionate at moderate to high levels. If present, the quantity of hydrocarbonaceous component should be at least about 0.1, preferably from about 0.5 wt.%> of the composition. Although about 7 or 8 wt.%), of the material can be employed, it is preferred to have a maximum of about 5 wt.%), preferably about 4.5 wt.%> of the composition. If a silicone is present in the composition, the minimum quantity is about 0.01 wt.%> of the composition, preferably at least about 0.1 wt.%>. The maximum can vary but generally is not above about 7 or 8 wt.%>, preferably about 5 wt.% 0 , more preferably about 4.5 wt.% 0 of the composition. When using a cationic polymer in the composition, the quantity of polymer is from about 0.01 to abut 3.0wt.%> of the composition preferably about 0.02 wt.% > as a minimum and more preferably about 0.03 wt.% as a minimum. The maximum is generally no more than about 0.9 wt.%>, or about 0.75wt.%, although lower maximums such as about 0.6wt.%> can be employed. The form of the composition can be liquid, solid or gel. The solids can be formulated into a "bar" which can be hand gel for cleansing purposes. The liquids can be formulated with such viscosities that are pourable from containers or expelled by a hand activated pump, for example. Fragrance benefits, used in this specfication, can include enhanced deposition on skin, extended release of fragrance from the skin, selective deposition on skin of specific compounds associated with providing an aroma, and the like. The fragrance should be present in quantities to provide an aroma. Generally, at least about 0.01 wt.%), preferably at least about 0.1 wt.%> of the composition is a fragrance. A maximum quantity is generally dependent upon the strength and quantity of aroma desired. Usually not more than about 2 wt.%>, preferably not more than about 1.5 wt.% of the composition of fragrance is employed.
