A composition causing different skin sensations
European Patent EP1121927
Publication date: Dec. 8, 2010
Assignee: Takasago International Corp.

The present invention relates to a composition including a cooling sensate, a warming sensate and a tingling-type sensate, which when used in combination, imparts an immediate initial sensation. The initial sensation can best be described as a tingling or a stinging impression, which also enhances the sensation of the other sensates used in the composition. In addition, the composition of the present invention also helps moderate the harsh and stimulative effects of the cooling agents.

Various types of products incorporate ingredients which impart some kind of sensation to the mucous membranes, oral cavity, throat or skin. These ingredients may be used as flavors or fragrances in a wide range of products such as personal care products (perfumes, deodorants, cosmetics, shampoos, skin creams, toothpastes and the like), pharmaceuticals (such as cough syrups, cough drops and the like) and foods (such as chewing gum, soda and the like). For example, ℓ-menthol and 3-(ℓ-menthoxy)propane-1,2-diol are used as active ingredients in products to impart a cooling sensation to the mouth or skin.

In the new sensate of the present invention, Jambu oleoresin is combined with a cooling sensate and a warming sensate to impart an immediate sensation upon contact that also provides an emollient effect on the cooling sensate. The cooling sensate can be a single cooling sensate or a combination of different cooling sensates. The warming sensate can be a single such sensate or a combination thereof. There are no specific limitations to the relative amounts of the compounds of the composition. However, it is preferred that vanillyl butyl ether is used in a relative amount with respect to the cooling agent so that no discernable warming effect occurs. Preferably, vanillyl butyl ether is used on a weight basis, from 1/1000 to 2 times as much as the cooling agent. More preferably, the vanillyl butyl ether is present in the composition from 1/200 to 1 time the amount of the cooling agent on a weight basis.
