Embodiment 1 and comparative example 1-3

[0034] Example 1 and Comparative Examples 1-3 (testing the effect of fragrance diffusion rate and persistence of fragrance composition)

[0035] The perfume compositions of Example 1 and Comparative Examples 1-3 as shown in Table 1 were prepared according to common methods. Then, the fragrance diffusion rate and durability of these fragrance compositions were evaluated in the following manner. In order to evaluate the persistence of the fragrance, the affinity of the fragrance was tested.

[0036] (Test method for fragrance diffusion rate and affinity of fragrance composition)

[0037] Place 10.0 mg of the prepared fragrance composition weighed out on filter paper into the bottom of a wide-mouth bottle with a diameter of 40 mm and a height of 50 mm. The bottle was closed and left for 30 minutes to prepare an evaluation sample. When opening the bottle, immediately evaluate the fragrance diffusion rate of the sample in a sensory way. In this open system, then, the sample is allowed ...

Embodiment 2 and comparative example 4

[0044] Example 2 and Comparative Example 4 (test effect of bath composition)

[0045] According to the formula shown in Table 4 below, 100 g of the bath compositions of Example 2 and Comparative Example 4 each containing 1.0% by weight of the perfume composition of Example 1 and Comparative Example 1 were prepared. Then, 20 grams of each of these bathing compositions were dissolved in 180 L of hot water at a temperature of 40-42°C. Experts immediately evaluated the relative scent intensity of these prepared solutions. The fragrance intensity of these solutions was also evaluated after 30 minutes. It was evaluated 3 times by 11 perfume experts with more than 5 years of experience (33 experts in total). This evaluation was performed relative to Comparative Example 4.

Abstract

A fragrance composition having an excellent diffusivity and long-lasting property of fragrance and a cosmetic, toiletry, bath composition, food and drink and pharmaceutical having an excellent diffusivity and long-lasting property of fragrance by using a novel fixative. A compound represented by the following general formula (1) is incorporated in a fragrance composition or the foregoing products. The amount of the compound of the general formula (1) to be incorporated in the fragrance composition is preferably from 0.01 to 90% by weight. The amount of the compound of the general formula (1) to be incorporated directly in the foregoing products is preferably from 0.0001 to 2.0 times (by weight) the weight of the aroma composition and / or composition to be incorporated therein. In this arrangement, a fragrance composition or products having an enhanced diffusivity and long-lasting property of fragrance can be obtained without causing any safety problem on human being. Wherein A represents H or OH group; B represents H or methyl group; and n represents an integer of from 0 to 2.

Description

Field of invention [0001] The present invention relates to a method for improving the diffusion rate and durability of fragrance, and an agent for enhancing the diffusion rate and durability of fragrance components and / or fragrance compositions, and relates to a fragrance composition having excellent diffusion rate and durability, And cosmetics, toiletries, bath products, foods, beverages, and medicines that contain these ingredients and have excellent fragrance diffusion and durability. technical background [0002] In order to prepare excellent fragrance compositions by mixing fragrances or such fragrance compositions with various products, various fixatives have been used so far in order to maintain the required fragrance diffusion rate for the fragrance compositions and various products. And adjust the fragrance performance and durability of spices. Known fixatives include various compounds such as dipropylene glycol, triethyl citrate, benzyl benzoate, benzyl salicylate, and ...
