[0041] Test Example: Sensory Evaluation of Amine Odor

[0042] After mixing 50 g of the agent 1 and 30 g of the agent 2 described in Table 4, hair dyeing was conducted by applying the mixture on a hair tress. The odor of amine was evaluated immediately after the dyeing, 20 minutes after the dyeing and after washoff.

[0043] The sensory evaluation was conducted by 15 people aged in their 20s to 40s with experiences in hair dyeing. Their average age was 31.5 years (5 men and 10 women). The criteria of the sensory evaluation was as follows.

[0044] Criteria of Sensory Evaluation

[0045] Score 1: Very intense amine odor (similar to squid smell).

[0046] Score 2: Intense amine odor.

[0047] Score 3: Moderate amine odor.

[0048] Score 4: Weak amine odor.

[0049] Score 5: Very weak amine odor.

[0050] The result of sensory evaluation immediately after the dyeing is shown in Table 5. The result of sensory evaluation 20 minutes after the dyeing is shown in Table 6. And, the result of sensory evaluation after the washoff is shown in Table 7.

[0051] Referring to the result of Table 5, there was a significant difference in amine odor between Comparative Example 1 not treated with a perfume and Comparative Example 2 treated with the existing perfume immediately after the dyeing. In addition the amine odor-masking effect was improved as the content of the aldehyde perfume was increased.

[0052] Referring to the result of Table 5 and Table 6, when comparing the results for Comparative Example 1 and Comparative Example 2 immediately after the dyeing and 20 minutes after the dyeing, the amine odor was stronger 20 minutes after the dyeing than immediately after the application of the hair dye. However, for Examples 1-9 wherein the aldehyde perfume was contained, the amine odor was comparable or slightly weaker 20 minutes after the dyeing.

[0053] Referring to the result of Table 7, the amine odor-masking effect was superior for Comparative Example 2 wherein the general-use perfume was contained as compared to Comparative Example 1 wherein no perfume was contained after washing off the hair dye, suggesting that a perfume has an odor-masking effect.

[0054] In addition, the odor-masking effect was more superior for Examples 1-9 wherein the aldehyde perfume composition was contained as compared to Comparative Example 2. The correlation coefficient was calculated to be 0.976, which suggests that the amine odor-masking effect is more superior as the content of the aldehyde perfume is higher.
