The present invention relates to a fragrance composition. Specifically, the present invention relates to a fragrance composition that has sensory stimulation.
In the related art, menthol, peppermint oil, vanillyl butyl ether, ginger oil, and the like as fragrance compositions used for the purpose of giving a cooling sensation or a warming sensation have been reported as sensory stimulation fragrance compositions (Patent Literatures 1 to 3 and Non Patent Literature 1).
However, in Patent Literatures 1 to 3 and Non Patent Literature 1, there is no mention of giving a warming sensation or a cooling sensation by sniffing through a nasal cavity and increasing or lowering a skin temperature.
It is known that a fragrance composition used for the purpose of giving a cooling sensation and a warming sensation is generally perceived subjectively through skin contact stimulation, including in the mouth, and does not lower the skin temperature even when coming into contact with the skin. In particular, a receptor that responds to the cooling sensation has been cloned and a mechanism of action has been elucidated. That is, it is known that physical cooling and components such as menthol have the following in common: activating the temperature receptor on the skin surface to excite cold fibers, and creating a sensation that the skin coated with menthol is cold, and do not lower the skin temperature. Similarly, a temperature receptor has been cloned for the warming sensation, and it is known that a similar mechanism causes a sensation that the skin is warm.
As a result of examining increase or lowering of the skin temperature due to non-contact of a fragrance component to the skin, the present inventors have found a solution consisting of the following composition, which is characterized by giving a warming sensation or a cooling sensation by sniffing through a nasal cavity and increasing or lowering the skin temperature. Thus, the present invention has been completed.
That is, the present invention includes the following contents.
According to the present invention, it is possible to provide a product that can appeal to a cooling or warming sensation effect not only for personal care and oral care in the related art, but also for a wide range of applications such as air care and fabric care.

It is preferable that one or more in the fragrance component group C are contained in the fragrance composition according to the present invention. A preferred range of a blending amount of the fragrance component group C in the fragrance composition is preferably 0.00001 mass % to 30 mass %, and more preferably 0.0001 mass % to 20 mass % in order to exhibit the effects of the present invention.
The fragrance composition according to the present invention can be prepared by appropriately adding and mixing various compounds, and the order and interval of blending are not particularly limited. The formulation form is also not particularly limited and can be appropriately selected depending on the purpose of use.
Known fragrance components or commonly used additives as described below can be incorporated into the fragrance composition according to the present invention within a range that does not impair the effects of the present invention, that is, within a quantitative and qualitative range that can give a cooling sensation and enhances lowering of the skin temperature or give a warming sensation and increases the skin temperature.
Examples of known fragrances include: hydrocarbons such as α-pinene, limonene, and cedrene; aliphatic saturated or unsaturated alcohols such as 1-octen-3-ol and nonanol; saturated or unsaturated chain terpene alcohols such as myrcenol, tetrahydrolinalool, and nerol; cyclic terpene alcohols such as α-terpineol and bornylmethoxycyclohexanol; sesquiterpene alcohols such as farnesol; aromatic alcohols such as γ-phenylpropyl alcohol and dimethylbenzyl carbinol; aliphatic aldehydes; terpene-based aldehydes; aromatic aldehydes; aliphatic ketones such as 7-acetyl-1,2,3,4,5,6,7,8-octahydro-1,1,6,7-tetramethylnaphthalene; terpene cyclic ketones; cyclic ketones; aliphatic esters; acetate esters; propionate esters; butyrate esters; benzoate esters; phenylacetate esters; salicylate esters; and anthranilate esters. Blending amounts of these known fragrance components in the present fragrance composition can be appropriately selected depending on the type of the fragrance to be blended, the purpose, or the like, and are not particularly limited.
The fragrance composition according to the present invention can be blended into, for example, a fragrance product, a detergent, a fabric softener, a cleaner, a kitchen detergent, a bleach, an aerosol agent, a deodorant/fragrant agent, incense, a miscellaneous good, food and beverages, and pharmaceuticals, and gives a cooling sensation and/or a warming sensation through the nasal cavity, and can thus be suitably used in a product not applied directly to the skin or to the mouth.
Examples of the detergent include a heavy laundry detergent, a light laundry detergent, a liquid detergent, a laundry soap, a compact detergent, and a powder soap. Examples of the fabric softener include a softener and a furniture care. Examples of the cleaner include a cleanser, a house cleaner, a toilet cleaner, a bathroom cleaner, a glass cleaner, a mold remover, and a drain cleaner. Examples of the kitchen detergent include a kitchen soap, a synthetic kitchen soap, and a dish detergent. Examples of the bleach include an oxidizing bleach (a chlorine bleach, an oxygen bleach, etc.), a reducing bleach (a sulfur-based bleach, etc.), and an optical bleach. Examples of the aerosol agent include a spray type and a powder spray. Examples of the deodorant/fragrant agent include a solid type, a gel type, and a liquid type. Examples of the miscellaneous good include tissue paper and toilet paper.
When the fragrance composition according to the present invention is blended in the above product, the amount may be determined as appropriate depending on the form and application of the product, and is not particularly limited. The amount is 0.0001 mass % to 100 mass %, preferably 0.001 mass % to 80 mass %, and more preferably 0.01 mass % to 50 mass %, based on a total mass of the product. When the amount is less than 0.0001 mass %, the fragrance component is too few to exhibit the desired cooling and warming sensation performance. When the amount is more than 80 mass %, a sufficient cooling or warming effect can be expected, but the cost may be too high, which may pose a commercial problem.
In addition, an effect of adjusting a sensible temperature and the skin temperature by the fragrance composition according to the present invention and a product containing the same is achieved within 5 minutes immediately after receiving olfactory stimulation, preferably 30 seconds to 4 minutes after receiving olfactory stimulation, and more preferably 1 minutes to 3 minutes immediately after receiving olfactory stimulation. It has been confirmed that when the time is longer than 5 minutes, the warming or cooling effect caused by olfactory stimulation weakens and returns to a steady state in a short period of time, which is a short-term lasting effect.

The effects of the fragrance compositions in Examples 1 and 2 and Comparative Examples 1 and 2 were determined by seven panelists using a peripheral skin temperature measurement method and subjective evaluation described below.
The peripheral skin temperature upon presentation of the fragrance composition was measured using a thermistor-type high-performance thermometer (LT-200SA, gram Inc.). A thermistor sensor was fixed to a nasal tip to measure a change in skin temperature at the nasal tip. The measurement was performed after 20 minutes or longer of acclimatization in a laboratory at 25° C. After a resting time as a control, a change in skin temperature was measured when a sample was presented. Experiment participants first rested for 5 minutes and then were exposed to 3.0 g of the sample presented to the tip of their nose for 5 minutes. The sample was presented in a light-shielding glass bottle at a position approximately 10 cm in front of the nasal cavity of the experimental participant.
A change in peripheral skin temperature was calculated by comparing the skin temperature at the start of sample presentation as a reference value with the skin temperature 150 seconds after sample presentation.
The subjective evaluation was performed after the sample presentation. The average value of sensory evaluation was calculated using the following evaluation criteria.
