However, among cosmetics containing chamomile extract, although emulsified cosmetics have a good feeling in use, they are sufficiently satisfactory in terms of the slight raw material odor derived from chamomile extract and the feel when applied to the skin. Was not.
Therefore, an object of the present invention is to provide a cosmetic containing a chamomile extract and having improved raw material odor and improved usability.

Therefore, the present inventor has prepared an emulsified cosmetic by blending a chamomile extract and an oil agent, and has variously studied the feeling of use and the fragrance thereof. It has been found that, when an emulsified cosmetic composition is prepared by mixing an oil agent and a specific sugar, an emulsified cosmetic composition having a good fragrance, less stickiness and less stickiness, and good elongation on the skin can be obtained, and the present invention is achieved. completed.

That is, the present invention provides the following components (A), (B), (C) and (D):
(A) Oil-soluble chamomile extract,
(B) Oil agent 0.1% by mass or more and 16% by mass or less,
(C) One or more saccharides selected from trehalose, inositol, erythritol and mannitol 0.1% by mass to 8% by mass, and (D) an emulsion cosmetic containing water.

The emulsified cosmetic composition of the present invention contains a chamomile extract, has a good scent, has little stickiness or stickiness, has good spreadability on the skin, and is excellent in usability.

The oil-soluble chamomile extract (A) used in the present invention is an extract of chamomile with an oil-soluble solvent, and includes both an extract solution with an oil-soluble solvent and a dry powder form obtained by drying the extract solution. From the viewpoint of improving various physiological effects, it is preferable to use the extract as an oil-soluble solvent.

Chamomile is a Japanese name for the annual plant chamomile (Scientific name: Matricaria recutita or Matricaria chamomilla) of the family Asteraceae (Compositae). Although there are various closely related species of chamomile, German chamomile is preferable from the viewpoint of physiological action. The chamomile may be extracted from any of whole plants, stems, leaves and flowers, but flowers are more preferable from the viewpoint of physiological action and aroma.

The solvent used for extracting the oil-soluble chamomile extract may be any oil-soluble solvent, but a lipophilic organic solvent is preferable from the viewpoint of obtaining an extract having excellent physiological action.

In addition, these may be plant-derived oils such as castor oil, persic oil, soybean oil, and sunflower oil. Generally, the type and amount of components contained in the extract differ depending on the lipophilic organic solvent used for extraction. In the present invention, an extract using squalane as a lipophilic organic solvent is preferable because it gives a particularly excellent physiological effect. The SP value is a measure of the compatibility between substances and can be determined by calculating the Hansen three-dimensional solubility parameter based on the method described in JP-A-10-194920.

The oil-soluble chamomile extract can be produced by, for example, extracting from chamomile using a lipophilic organic solvent by the method described in JP-A-10-194920. Specifically, it is preferable to add 1 to 100 times the amount of the lipophilic organic solvent to the dried chamomile flowers to the crushed dried chamomile flowers, and perform stirring and extraction at 10 to 90°C for 1 to 96 hours.

Examples 1-19 and Comparative Examples 1-7
An emulsified cosmetic (O/W) was produced by emulsifying using the components shown in Table 1 and Table 2. That is, the aqueous phase components (components (C), (D), (E), (F) and others) are heated and mixed at 80°C. On the other hand, the oil phase components (components (A) and (B)) are heated and mixed at 80°C. The oil phase was added to the aqueous phase at 80° C. and mixed with a propeller stirrer (300 rpm) to further emulsify the oil phase and further mix with a homomixer (1500 rpm) to reduce the size of the emulsified particles. After that, the homomixer was stopped and the mixture was cooled to 30° C. while continuing mixing with a propeller stirrer (300 rpm) to obtain an emulsified cosmetic. The obtained emulsified cosmetic was used to evaluate the scent and the feeling of use.

<Evaluation method>
(1) Evaluation of fragrance One expert panelist thoroughly washed the hands with a commercially available fragrance-free facial cleanser (Curel Foam Facial Cleanser, manufactured by Kao Corporation) and wiped it well with a towel. Then, place 0.1 mL of the emulsified cosmetic on the back of one hand, and use 3 fingers other than the thumb and little finger of the other hand, 1st to 3rd joints to make 1 rotation per second and draw a circle with a diameter of 6 cm. Thus, the odor of the back of the hand coated with the emulsified cosmetic was evaluated after 60 seconds. The case where the raw material odor was not felt at all was rated as 5, and the case where the raw material odor was felt very much was rated as 1 and was evaluated on a scale of 5 levels.

(2) Evaluation of feeling of use (a) Elongation at the time of application The emulsified cosmetic composition was applied to the back of the hand in the same manner as the method for evaluating the scent. In the first 5 seconds after the emulsified cosmetic was started to be extended, the case where no resistance was felt at all was 5 and the case where resistance was felt very much was set to 1 and was evaluated on a scale of 5 levels.
