Description

  The present invention relates to a cosmetic composition.

  In various cosmetics such as cleaning agents and deodorant agents, green tea extract is used as a natural deodorant component (see Patent Document 1). However, if the concentration of the green tea extract in the cosmetic is increased to enhance the deodorizing effect, there is a problem that the extract odor peculiar to the green tea extract becomes stronger. Masked deodorant cosmetics are known (see Patent Document 2).

JP 2014-47165 A JP 2011-116667 A

  However, when the odor of the green tea extract is masked by the fragrance compound as in the deodorant cosmetic described in Patent Document 2, the fragrance itself of the fragrance itself used for masking becomes stronger, and the fragrance becomes stronger as a whole cosmetic. It may be too much. In particular, detergents used by foaming body soap and the like tend to have a fragrance, and the tendency of the smell of green tea extract and fragrance to be too strong compared to other cosmetics is remarkable.

  An object of the present invention is to provide a cosmetic composition in which the odor of the green tea extract is reduced and the cosmetic as a whole has an appropriate fragrance even if it contains a high concentration of the green tea extract. .

The present invention
Ingredient A: Green tea extract,
Component B: Synthetic aldehyde, and Component C: a cosmetic composition containing rosemary oil and / or eucalyptus oil, wherein the content of Component A is 0.01 to 1.0% by mass, It is related with the cosmetics composition whose mass ratio (component B / component A) of the said component B with respect to the said component A is 0.005-0.1.

  ADVANTAGE OF THE INVENTION According to this invention, even if it contains a high concentration green tea extract, the odor of a green tea extract can be reduced and the cosmetic composition which has moderate aromaticity as the whole cosmetics can be provided.

The cosmetic composition of the present invention comprises:
Ingredient A: Green tea extract,
Component B: contains cinnamon oil and / or cinnamic aldehyde, and component C: contains rosemary oil and / or eucalyptus oil. Synamic aldehyde has a high masking action on the odor of the green tea extract, and the odor of the green tea extract can be reduced. However, since the dynamic aldehyde itself also has a strong odor, if the odor of the green tea extract is masked only with the cinnamaldehyde, the odor of the cinnamaldehyde will become stronger. Therefore, in the present invention, it is found that the fragrance of the entire cosmetic is moderately harmonized mainly by “matching” by further adding rosemary oil and / or eucalyptus oil to the cosmetic composition. It was. “Masking”, which masks bad odors with a strong scent, is a technology that is designed to feel bad smells and make them feel good as a whole by combining scents that harmonize with bad smells. Marie oil and eucalyptus oil have a masking action on the odor of the green tea extract, but can be blended with the odors of both the green tea extract oil and the cinnamon oil and can be blended into a soft scent. Thus, according to the present invention, the odor of the green tea extract is reduced despite containing a relatively large amount of the green tea extract, and the fragrance is too strong for the entire cosmetic composition. No cosmetic composition can be obtained.

  Component A is a green tea extract. The green tea extract is an extract obtained by extraction from green tea. The extraction method is not particularly limited, and examples thereof include a dry distillation method and a solvent extraction method.

(Evaluation)
About 5 g of each cosmetic composition obtained in the examples and comparative examples was picked up, and a small amount of water was added to lather, and then the fragrance was evaluated. The results are shown in Tables 2 and 3. The evaluation was performed by three professional evaluators, and the evaluation of each evaluator was comprehensively determined.

(1) Tea odor The strength of the odor of the green tea extract (green tea dry distillation extract) was evaluated according to the following criteria.
A (Excellent): The smell of the green tea extract is not felt at all or is faintly felt.
○ (Good): The green tea extract smells weak.
X (defect): The smell of the green tea extract is clearly felt.

(2) Keihi odor The strength of the odor of the synthetic aldehyde (keihi oil) was evaluated according to the following criteria.
A (excellent): The smell of the synamic aldehyde is not felt at all or is faintly felt.
○ (Good): The smell of synamic aldehyde is felt weak.
X (Bad): The smell of synamic aldehyde is clearly felt.

(3) Odor of the entire cosmetic composition A (excellent): The odor of the entire cosmetic composition is very weak.
○ (Good): The odor of the entire cosmetic composition is weak.
X (defect): The smell of the whole cosmetic composition is strong.

From the above results, it can be seen that the cosmetic compositions of Examples 1 to 8 have the tea odor and Keihi odor suppressed, and the odor of the entire cosmetic composition is also suppressed.
On the other hand, in Comparative Example 1, the amount of cinnamic aldehyde is too small to suppress the tea odor, and in Comparative Example 2, the amount of cinnamic aldehyde is too large to suppress the cha odor, The Keihi smell is tight.
Similarly, even in Comparative Examples 3 and 7 that do not contain rosemary oil and eucalyptus oil, the tea odor can be suppressed, but the cinnamon odor is tight. Moreover, even in Comparative Examples 4 to 6 containing other perfume oil instead of rosemary oil and eucalyptus oil, the cinnamon odor cannot be suppressed.
In Comparative Examples 8 and 9 containing other aldehydes instead of the synthetic aldehydes, the tea odor cannot be suppressed.

  Formulation examples of the cosmetic composition of the present invention are shown in Tables 4-6.

  The cosmetic composition of the present invention can be used as a cleaning agent, a deodorant agent and the like.
