Description

The effect of cosmetics is to keep the skin clean and healthy according to the Pharmaceutical Affairs Law, and moisturizing ingredients, whitening ingredients, anti-inflammatory ingredients, etc. have been developed and formulated. However, the function of cosmetics is not limited to such a function, but it is also certain that there is a favorable effect induced by comfort by using the cosmetic. On the other hand, it is also known that psychological conditions such as stress overload induce rough skin, and using cosmetics has a direct effect on the skin and is also used at the same time. through the comfort sensitive to induce relaxation of psychological aspects, than Te, it is thought as that exerts also indirectly improves the action of the skin condition from the inner surface (e.g., Patent documents 1 2, Patent Document 3, Patent Document 4, Patent Document 5, Patent Document 6, and Patent Document 7) . Furthermore, as the element acting in such psychological aspects, without stopping to tactile stimulation of feeling, that have been known to also achieved by visual stimuli (e.g., see Patent Document 8). As described above, it can be said that it is desired to adjust the tactile sensation to a preferable state in use in a skin external preparation administered to the skin which is a sensitive sensory organ such as cosmetics.

Organically-modified clay minerals such as dimethyl distearyl ammonium modified hectorite forms an oil component and a gel, resides the property of incorporating water into the gel, by utilizing this property, that has been used as an emulsifying component ( for example, see Patent Document 9, Patent Document 10). Further, N-lauroyl-L-glutamate di (cholesteryl / behenyl / octyldodecyl), N-lauroyl-L-glutamate di (cholesteryl / octyldodecyl), N-lauroyl-L-glutamate di (phytosteryl / behenyl / octyldodecyl) , N- lauroyl -L- diester of acylated glutamate such as glutamic acid di (phytosteryl / octyldodecyl) is that known to be incorporated into cosmetics as an amino acid derivative useful oil as a carrier for active ingredients sparingly soluble ( For example, refer to Patent Document 11) . Also, extracts of clove, the hair cosmetic composition, that is known to be contained in the skin-beautifying cosmetics (e.g., refer to Patent Document 12, Patent Document 13, Patent Document 14). However, an emulsifier form containing 1) an extract of the fruit of Cestoniaceae, 2) an organically modified clay mineral, and 3) a dialkyl (carbon number) ester of N-acyl (carbon number 10-30) glutamic acid No external preparation for skin is known, and it is not known at all that it is possible to obtain an external preparation for skin having a feeling of use that induces tactile stimulation suitable for stress relaxation at the time of use by adopting such a configuration. .

In view of such a situation, the present inventors have made extensive research efforts in search of a water-in-oil emulsifier form that is stable and suitable for stress relief, and that is comfortable in use. An emulsifier-type skin comprising 1) an extract of the fruit of Cestoniaceae, 2) an organically modified clay mineral, and 3) a dialkyl (carbon number) ester of N-acyl (carbon number 10-30) glutamic acid The inventors have found that an external preparation has such characteristics, and have completed the invention. That is, the present invention is as follows.
(1) It contains 1) an extract of the fruit of the myrtaceae clove, 2) an organically modified clay mineral, and 3) a dialkyl (carbon number) ester of N-acyl (10 to 30 carbon atoms) -modified glutamic acid. An emulsifier type external preparation for skin.
(2) extract of the fruit of the Myrtaceae clove is, which is defined eugenol as an indicator substance, and wherein a content of the eugenol is 1 to 10 mass% with respect to extract the total amount The external preparation for skin according to (1).
(3) The skin external preparation according to (1) or (2), wherein the extract of the fruit of the Myrtaceae clove is obtained by extracting the fruit of the Myrtaceae clove with alcohol.
(4) The skin external preparation according to any one of (1) to (3) , wherein the organically modified clay mineral is dimethyl distearyl ammonium modified hectorite.
(5) The skin external preparation according to any one of (1) to (4) , wherein the emulsifier form is an oil-in-water oil emulsifier form.
(6) The external preparation for skin according to any one of (1) to (5) , wherein the external preparation for skin is a cosmetic that imparts a feeling of stability to the mind through its feeling of use.
(7) The external preparation for skin according to (6) , wherein the external preparation for skin has an indication that it is a cosmetic that imparts a sense of stability to the mind through its feeling of use.
