Description

SKIN CLEANSING COMPOSITION THAT PROVIDES AN IMPROVED PERFUME DEPOSIT Background of the Invention Fragrances have been used in skin care compositions for hundreds of years. These fragrances have a number of uses. These provide a recognizable scent for the user of the composition or a person in close juxtaposition to that person. Fragrances mask the odor produced by the bacteria that grows on the skin. The fragrances can work as a solubilizing agent for the organic materials in the composition. However, the effects on the skin care compositions, particularly those of the "rinse" type, are not of long duration. Assuming they remain on the skin during the small time contact and are not washed during the skin care process, their adherence to the skin may be weak and / or their skin detachment occurs at a rapid rate, so It does not leave any significant odor after a short period of time after rinsing. Therefore in order to provide an appropriate fragrance to the upper space above the skin, there must be a proper combination of amount of fragrance in the skin, adhesion to the skin and its release from the skin over a period of time appropriate. This combination may provide a "persistent" odor over a significant period of time.

A new composition has been discovered which can provide these benefits of the fragrance. The composition is a rinse cleansing composition which provides an improvement in the benefits of the fragrance.

Synthesis of the Invention According to the invention, there is a method for cleansing the skin and providing an increased fragrance benefit after rinsing the skin of the cleansing composition which comprises, applying to the skin a composition having: a: one or a mixture of surfactants in an amount sufficient to clean the skin; b: a fragrance in sufficient quantities to provide a scent; c: a silicone or a hydrocarbonaceous component or mixtures thereof in sufficient amounts to originate the increased fragrance benefits; and rinsing 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 recurs. Examples of such materials are those that boil at temperatures below about 500 ° C. The highly volatile, low boiling perfume ingredients typically have boiling points of around 250 ° C or lower. The moderate volatile perfume ingredients are those that have boiling points of about 250 ° C to about 300 ° C. The less volatile, high-boiling perfume ingredients are those that have boiling points of about 300 ° C to about 500 ° C.

More preferably, there is zero or about 2 percent weight of another surfactant thereof. Bars having a small amount of soap within the range of the soap usually have a mild synthetic surfactant thereon such as sodium cocoyl isethionate at moderate to high levels.

If present, the amount of hydrocarbonaceous component should be at least about 0.1, preferably about 0.54 weight percent of the composition. Although about 7 or 8 percent by weight, material can be employed, it is preferable to have a maximum of about 5 percent by weight, preferably about 4.5 percent by weight of the composition. If a silicone is present in the composition, the minimum amount is about 0.01 percent by weight of the composition, preferably at least about 0.1 percent by weight. The maximum may vary but is generally not above about 7 or 8 percent by weight, preferably about 5 percent by weight, more preferably about 4.5 percent by weight of the composition.

When a cationic polymer is used in the composition, the amount of polymer is from about 0.01 to about 3.0 weight percent of the composition preferably about 0.02 weight percent as a minimum and more preferably about 0.03 weight percent as a minimum. The maximum is generally no more than about 0.9 percent by weight, or about 0.75 percent by weight, although lower maximums such as about 0.6 percent by weight can be employed.

The form of the composition can be liquid, solid or gel. The solids can be formulated in a "bar" which can be hand gel for cleaning purposes. Liquids can be formulated with such viscosities to be pourable from containers or for example expelled by means of a pump activated by hand.

The benefits of the fragrance, used in this specification, may include an improved deposit on the skin, extended release of the fragrance from the skin, selective deposit on the skin of the specific compounds associated with providing a scent, and the like. The fragrance should be present in amounts to provide a scent. Generally, at least 0.01 weight percent, preferably at least about 0.1 weight percent of the composition is a fragrance. A maximum amount is generally dependent on the strength and the amount of aroma desired. Usually no more than about 2 percent by weight, preferably no more than about 1.5 percent by weight of the fragrance composition is employed.

Claims (8)

R E I V I N D I C A C I O N S

1. A method for cleansing the skin and providing an increased fragrance benefit after rinsing the skin of the cleansing composition comprising applying to the skin a composition having: a) one or a mixture of surfactants in an amount sufficient to clean the skin, b) a fragrance in sufficient quantities to provide a scent, c) a silicone, a hydrocarbonaceous component or a mixture thereof in amounts sufficient to provide an increase in the benefit of the fragrance, and rinsing said composition.

2. The method as claimed in clause 1 characterized in that the cationic polymer is also present in the composition.

3. The method as claimed in clause 1 characterized in that from 0 to less than about 0.01% by weight of a silicone is present in a 1 composition and the hydrocarbonaceous component is present.

. The method as claimed in clause 1 characterized in that from 0 to less than about 0.1% by weight of the hydrocarbonaceous component is present in the composition and the silicone component is present.

5. The use of a composition comprising: a) one or a mixture of surfactants in an amount sufficient to clean the skin, b) a fragrance in sufficient quantities to provide a scent, c) a silicone, a hydrocarbonaceous component or a mixture thereof in amounts sufficient to provide an increase in the fragrance benefit, in the preparation of a skin cleansing composition that provides an increased fragrance benefit.

6. The use as claimed in clause 5 characterized in that the benefit is the increased deposition of the fragrance on the skin.

7. The use as claimed in clause 1 characterized in that the benefit is the extended release of the fragrance from the skin.

8. A composition comprising (a), (b), and (c) as claimed in clause 1. SUMMARY A method for cleansing the skin and providing an increased fragrance benefit after rinsing the skin of the cleansing composition which comprises applying to the skin a composition having: (a) one or a mixture of surfactants in an amount sufficient to clean the skin; (b) a fragrance in amounts sufficient to provide a scent; (c) a silicone, a hydrocarbonaceous component or a mixture thereof in amounts sufficient to obtain an increased fragrance benefit, and a rinse of said composition.
