Description

  The present invention relates to a fragrance composition having a changed fragrance and a skin cosmetic composition containing the fragrance composition.

  In general, it is known that the fragrance of a blended fragrance for products changes gently with time. Conventional blended fragrances have been studied for a configuration in which the scent of the scent does not change from the beginning to the end as much as possible, or a single scent continues.

  On the other hand, as a technique for intentionally changing the scent, two types of microcapsules are used, and fragrance components with different volatility are contained in these or the wall thickness of the microcapsules is changed to control scent volatilization. A method (Patent Document 1) and a method of stacking two or more fragrance component-containing layers containing different fragrance components (Patent Document 2) have been proposed.

Special Table 2003-500426 JP 2008-56613 A

  However, all of the techniques described in Patent Document 1 or 2 change the scent by using a fragrance holder (microcapsule or fragrance component-containing layer), and the fragrance composition alone changes the scent. It will not be realized. Therefore, the present invention provides a fragrance composition that can change the fragrance abruptly in a short time and make it feel two or more comfortable fragrances regardless of the use of the fragrance holder. The purpose is to provide.

  The present inventors have found that the above object can be achieved by combining two specific groups of fragrances.

Test example 1
The massage cream dough shown in Table 1 was fragranced with the fragrance shown in Table 2 alone, and the change in fragrance was evaluated.

(Evaluation method)
Each fragrance | flavor component was fragrance | flavored to the compounding prescription (Table 1) of a massage cream alone.
The scented massage cream was applied to the back of the hand and massaged for 3 minutes, and the intensity of the scent for each minute was evaluated in 6 levels from 0 to 5 according to the following criteria. When the intensity of the fragrance changed during 1 minute, the evaluation was made based on the highest intensity during that period.
The evaluation was conducted by two expert panelists, and the results of the discussion between the two are shown in Table 2. In addition, the intermediate case between grade 2 and grade 3 was set to “2.5”, and the intermediate case between grade 3 and grade 4 was set to “3.5”.

(Evaluation criteria)
5: Smells very strongly 4: Smells strongly 3: Smells clearly 2: Smells weakly 1: Slightly smells 0: Does not smell

  Since it is desirable that the material suitable as component A disappears quickly after massage, the score of 0-1 min-1 -2 min -2-3 min is 5-0-0. Materials suitable as component B are those having a 0 to 1 minute score of 3 or less and a 1 to 2 minute score of 3 or more. Materials suitable as component C are those having a score of 0 to 1 minute of 3 or less and a score of 2 to 3 minutes of 3 or more.

Examples 1 to 10 and Comparative Example 1
The fragrance | flavor composition shown in Table 3 was prepared, and the change of the fragrance was evaluated by the following method.
Examples 1 to 8 are reference examples and are not included in the scope of the claims.

(Evaluation method)
The fragrance | flavor composition of each Example or the comparative example was scented to the mixing | blending prescription (Table 1) of a massage cream (fragrance | flavor rate 0.2 mass%).
After applying the scented massage cream on the back of the hand, the degree of change in fragrance was evaluated in three stages according to the following criteria while massaging for 3 minutes.
The evaluation was performed by 4 expert panelists, and Table 3 shows the average value of 4 persons with each evaluation.

(Evaluation criteria)
3: I felt the change of fragrance clearly in the middle of evaluation 2: I felt a little change in fragrance in the middle of evaluation 1: I did not feel the change of fragrance in the middle of evaluation

Test Example 2 Change in Comfort with Massage Cream Flavored Product For the fragrance composition of Example 9 and Comparative Example 1, the change in comfort due to the scent was evaluated by the following method.

(Evaluation method)
The fragrance composition of Example 9 or Comparative Example 1 was perfumed (perfume rate 0.2 mass%) in the massage cream formulation (Table 1).
Apply 4g of scented massage cream thinly and evenly on the inside of the small cup, and after 30 seconds, present the scent to a specialized panelist. Table 4 shows the feeling of comfort (freshness, calmness) at that time. Evaluation was performed using the free scale shown. The evaluation was performed by having a pencil mark it as indicated by the diagonal lines in the free scale.

Next, after continuing to rub the portion where the massage cream was spread for 3 minutes in a small cup, the smell was presented to a specialized panelist and the same answer was given. This evaluation was similarly performed for the massage creams of Example 9 and Comparative Example 1.
Evaluation was performed by 11 expert panelists in Example 9 and 7 expert panelists in Comparative Example 1, and Table 5 shows numbers obtained by measuring the distance from the right end of the free scale.
As a result, compared with Comparative Example 1, it was measured that the comfort feeling of “fresh feeling” was lower and the comfort feeling of “gentle feeling” was higher from the beginning to the end of the measurement. .
