Japanese Unexamined Patent Publication No. 7-25742 Japanese Unexamined Patent Publication No. 8-73324 Japanese Unexamined Patent Publication No. 8-92056 Japanese Unexamined Patent Publication No. 10-72336 JP-A-2007-161666

However, in recent years, the level of consumer demand has increased, and among cosmetics containing chamomile extract, emulsified cosmetics have a good usability, but have a slight raw material odor derived from chamomile extract and when applied to the skin. The existing cosmetics were not sufficiently satisfactory in terms of the feel and the like.
Therefore, an object of the present invention is to provide a cosmetic containing a chamomile extract, which has an improved raw material odor and a further improved usability.

Therefore, the present inventor has produced an emulsified cosmetic by blending a chamomile extract and an oil agent, and has studied various feelings and aromas thereof. As a result, an oil-soluble chamomile extract was adopted as the chamomile extract. If an oil agent, 1,3-propanediol and a specific surfactant are mixed to make an emulsified cosmetic, an emulsified cosmetic having a good fragrance, less stickiness and stickiness, and good spread on the skin can be obtained. We have found that it can be obtained and completed the present invention.

That is, in the present invention, the following components (A), (B), (C), (D) and (E):
(A) Oil-soluble chamomile extract,
(B) Oil agent 0.1% by mass or more and 20% by mass or less,

(D) One or more surfactants selected from polyoxyethylene alkyl ethers, polyglycerin fatty acid esters, sucrose fatty acid esters, alkyl glucosides, anionic surfactants and cationic surfactants 0.005 mass by mass It provides an emulsified cosmetic containing% or more and 4% by mass or less, and (E) water.

The emulsified cosmetic of the present invention contains a chamomile extract, has a good scent, is less sticky and sticky, has good spread on the skin, and has an excellent usability.

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

Chamomile is the Japanese name for the annual herb chamomile (scientific name: Asteraceae (Composite)) Mayweed genus (scientific name: Asteracea recutita or Matrixaria chamomile). There are various closely related species of chamomile, but German chamomile is preferable from the viewpoint of physiological action. The chamomile extraction site may be whole plant, stem, leaf or flower, but flower is more preferable from the viewpoint of physiological action and fragrance.

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

Further, 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 the 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 refers to a measure of compatibility between substances, and is obtained by calculating Hansen's three-dimensional solubility parameter based on the method described in JP-A-10-194920.

The oil-soluble chamomile extract can be produced, for example, by extracting from chamomile with a lipophilic organic solvent by the method described in JP-A-10-194920.

At a temperature of 80 ° C., the components (A), (B), (D) and other oily components were heated and mixed with a propeller stirrer under a stirring condition of 300 rpm to obtain an oil phase. Then, at 80 ° C., an oil phase was added to the aqueous phase, and the mixture was mixed with a propeller stirrer under stirring conditions of 300 rpm, and then cooled to 25 ° C. at a speed of 1 ° C./1/1 minute to obtain an emulsified cosmetic. Using the obtained emulsified cosmetics, the scent and the feeling of use were evaluated. The results are shown in Tables 1 and 2.

<Evaluation method>
(1) Fragrance A panelist specializing in fragrance washed his hands thoroughly with a commercially available unscented washing pigment (Curel foam washing pigment manufactured by Kao Corporation) and wiped them thoroughly with a towel. Then, 0.1 mL of emulsified cosmetic was placed on the back of the hand on one side. Using 3 fingers other than the thumb and little finger of the other hand, and the 1st to 3rd joints, make one rotation per second and extend for 60 seconds in a circle with a diameter of 6 cm. The case where the raw material odor was not felt most after 60 seconds was set to 9, and the case where the raw material odor was felt most was set to 1, and the evaluation was made on a 9-point scale.

(2) Nobi One expert panelist washed his hands thoroughly with a commercially available unscented washing pigment (Curel foam washing pigment manufactured by Kao Corporation) and wiped them thoroughly with a towel. Then, 0.1 mL of emulsified cosmetic was placed on the back of the hand on one side. Using 3 fingers other than the thumb and little finger of the other hand and the 1st to 3rd joints, make one rotation per second and extend it in a circle with a diameter of 6 cm. The case where the feeling of resistance was the least in the first 5 seconds of stretching was set to 9, and the case where the feeling of resistance was the highest was set to 1, and the evaluation was made on a 9-point scale.

(3) Stickiness (horizontal direction)
One expert panelist washed his hands thoroughly with a commercially available unscented washing pigment (curél foam washing pigment manufactured by Kao Corporation) and wiped them thoroughly with a towel. Then, 0.1 mL of emulsified cosmetic was placed on the back of the hand on one side. Using 3 fingers other than the thumb and little finger of the other hand, and the 1st to 3rd joints, make one rotation per second and extend for 60 seconds in a circle with a diameter of 6 cm. After that, when the other palm or finger is pressed against the back of the hand to which the emulsified cosmetic is applied and moved horizontally, the case where it is most difficult to stick horizontally is 9 and the case where the skin sticks to the hand most horizontally is 1 , Evaluated on a 9-point scale.

(4) Stickiness (vertical direction)
One expert panelist washed his hands thoroughly with a commercially available unscented washing pigment (curél foam washing pigment manufactured by Kao Corporation) and wiped them thoroughly with a towel. Then, 0.1 mL of emulsified cosmetic was placed on the back of the hand on one side. Using 3 fingers other than the thumb and little finger of the other hand, and the 1st to 3rd joints, make one rotation per second and extend for 60 seconds in a circle with a diameter of 6 cm. After that, when the other palm or finger is pressed against the back of the hand to which the emulsified cosmetic is applied and moved in the vertical direction, the case where it is most difficult to stick in the vertical direction is 9, and the case where the skin sticks to the hand in the most vertical direction is 1. , Evaluated on a 9-point scale.
