Description

  The present invention relates to a perfume booster composition used to enhance the perfume persistence of a perfume. Furthermore, this invention relates to the fragrance | flavor composition and fragrance | flavor composition containing the said fragrance | flavor booster composition.

  In recent years, with the diversification of palatability for fragrance, various fragrance compositions using natural and synthetic fragrances have been developed, and various fragrance compositions such as fragrance deodorants, cosmetics, cleaning agents, foods, etc. It is used by adding to perfumed products in the field (for example, see Patent Document 1). Such scented products are required to release a persistent and homogeneous scent during the period of use.

  However, in general, fragrances are used in combination with various fragrance ingredients with different volatilization rates, so the quality and strength of the fragrance released from the scented product may change or attenuate during the period of use. There is a drawback that it will be. In addition, human olfactory sensation is a property that becomes insensitive to scents in daily life and scents in daily living space (hereinafter, this property may be referred to as “nasal habituation”). There is. In fact, in an environment where a certain aroma is released, a person who is not used to the nose can perceive the aroma sufficiently, but a person who is accustomed to the nose may not be able to perceive the aroma.

  Therefore, no matter how new and unique fragrances have been developed in the past, the quality and strength of the fragrance may not be maintained uniformly. In addition, in the case of conventional fragrances, in combination with the decrease in fragrance quality and strength due to the passage of the usage period and the user's habituation, the user accelerates the fragrance as the usage period elapses. May become impossible to perceive.

Against the background of such conventional technology, we have developed a fragrance composition that can continuously release a homogeneous fragrance, and in particular, a fragrance composition that can be perceived without losing the quality or strength of the fragrance even when used for a long time. There is a need to provide a perfumed composition using the perfume composition.

From these results, a perfume booster composition containing [compound of general formula (A-2-2)] / [compound of general formula (A-1-2)] at 1 / 1.25 to 1/20 (implementation) When Examples 7-1 to 7-7) were used, it was confirmed that the fragrance strength was the same immediately after the start of volatilization and after the weight reduction, and the scent image did not change. That is, it was confirmed that the aroma of the fragrance can be sufficiently perceived with the scent image kept constant as the use period elapses. On the other hand, when the fragrance booster composition was not blended, the intensity of the fragrance felt weak after weight reduction, and the fragrance of the fragrance could not be perceived sufficiently. In addition, the compatibility between the scent image and the actual scent was lowered.

試験例８
試験例１に記載の「液体芳香消臭剤の調製」に従って、実施例1-4又は比較例1-1のブースター組成物とラベンダー香料を用いて、液体芳香消臭剤を調製した。各液体芳香消臭剤につきそれぞれ５０名のモニターに生活空間の中で使用してもらい、香りの強さを５段階（満足、やや満足、どちらともいえない、やや不満、不満）で評価させた。なお、液体芳香消臭剤は約１２帖の部屋に設置し、香りの評価時期は、揮散開始から３０日後（減量率：約３０％）および６０日後（減量率：７０％）とした。

Test Example 8
According to “Preparation of liquid aroma deodorant” described in Test Example 1, a liquid aroma deodorant was prepared using the booster composition of Example 1-4 or Comparative Example 1-1 and a lavender fragrance. Each liquid fragrance deodorant was used by 50 monitors in the living space, and the intensity of the scent was evaluated in five levels (satisfactory, slightly satisfied, neither can be said, somewhat dissatisfied, dissatisfied). . The liquid aroma deodorant was installed in a room of about 12 cm, and the fragrance evaluation time was 30 days after the start of volatilization (weight reduction rate: about 30%) and 60 days after (weight reduction rate: 70%).

  The results obtained are shown in Table 28. From this result, when a fragrance booster composition containing [compound of general formula (A-2-1)] / [compound of general formula (A-1-2)] at a specific ratio is used, the weight loss rate is 30%. It was confirmed that the fragrance of the fragrance could be sufficiently perceived as the use period progressed without the decrease in the intensity of the fragrance being felt. On the other hand, the specific gravity of [compound of general formula (A-2-1)] / [compound of general formula (A-1-2)] in the fragrance booster composition is less than 1/1. In the case of a large amount, after the weight reduction, after the weight reduction, the intensity of the fragrance felt weak, and the fragrance of the fragrance could not be sufficiently perceived, and the user's satisfaction could not be obtained. In addition, by adjusting the pH of the liquid fragrance deodorant prepared using the booster composition of Example 1-4 and the lavender fragrance to pH 9.5 with diethanolamine, the evaluation after 60 days of evaluation time was “satisfied”. The ratio of can be increased to 36%.
