ABSTRACT:
FIELD OF THE INVENTION
This invention relates to fragrance enhancing compositions which may be used in a variety of products, especially in underarm products such as deodorants and antiperspirants, to give a deodorant effect against malodor from underarm perspiration and enhance the performance of the fragrance components of such products.
BACKGROUND OF THE INVENTION
A variety of approaches have been and continue to be taken for reducing and or eliminating human body malodor, especially from underarm perspiration. These approaches include reducing/eliminating perspiration itself, reducing/eliminating odor at the root cause (for example, interfering with the degradation of perspiration on skin caused by the action of bacteria) as well as masking the odors themselves.
U.S. Pat. No. 5,540,853 to Trinh et al describes personal treatment compositions and cosmetic compositions containing enduring perfume wherein the enduring perfume is evaluated by a “calculated log P” parameter. PCT application WO 97/30689 to Trinh et al describes personal treatment compositions which can be used as leave-on products which are evaluated by the same criteria.
EP patent application 0 760 243 A1 to Groverman et al describes the use of allylic perfumes as a malodor reduction agent.
EP patent application 0 545 556 A2 to Behan et al teaches a perfume composition containing at least 50% by weight of specific components (in minimum percentages of each component) selected from the group consisting of ethers, salicylates, alcohols, acetate/propionate esters and methyl ethyl ketones where members of at least 4 of the groups must be included.
U.S. Pat. No. 5,601,809 teaches the neutralization of axillary malodor.

U.S. Pat. No. 5,354,737 to Barr et al describes selected fragrancing compositions such as Tonalid in deodorant products.
There is still a need, however, for improving the way that cosmetic compositions are fragranced. Thus it is an object of the invention to provide fragrancing compositions which are useful in controlling malodor, especially underarm malodor. It is another object of this invention to provide fragrance enhancing components of a fragrance system for cosmetic products so that the amount of the overall fragrance components can be reduced. It is a further object of the invention to provide fragrance enhancing components that improves the performance of conventional fragrancing products. It is still another object of the invention to reduce the overall irritation potential of cosmetic products by reducing the amount of fragrance needed to provide a satisfactory product. It is also an object of the invention to provide fragrancing compositions which exhibit improved ability to mask underarm odor. It is yet another object of the present invention to provide improved underarm products such as deodorants and antiperspirants containing such fragrancing compositions. These and other objects of the invention will become apparent from the following description of the invention.
SUMMARY OF THE INVENTION
This invention relates to fragrance enhancing compositions which are capable of controlling malodor from a human body to a significant extent thereby reducing the overall amount of fragrance required to achieve a satisfactory cosmetic product, especially an underarm product. The fragrance enhancing compositions of the invention are formulated with selected components with high olfactory impact properties and good substantivity (for example, 24 hour endurance) which are combined for controlling human malodor, especially underarm sweat malodor. The fragrances made with the fragrance enhancing compositions of this invention are long lasting (enduring) as evaluated by accepted panel evaluations. By using the compositions of this invention it may also be possible to lower the amount of fragrance normally used in such cosmetic products (usually in the range of 0.1-10% by weight based on the total weight of the cosmetic composition) to some lesser amount.
The fragrance enhancing compositions of this invention are made by combining at least three components from the group consisting of the following non-nitromusk materials:
(1) Cinnamon Leaf Oil Ceylan {a Natural Essential Oil—predominantly 2-methoxy 4 allyl phenol};
(2) Vetiver Oil Java {a Natural Essential Oil—predominantly Vetiverol alcohol};

(7) Cassis 345 B {a multi-component proprietary formulation available from Firmenich SA, Geneva, Switzerland; this material is primarily composed of alcohols and esters with minor amounts of natural extracts from essential oils};
