Description

Percutaneous is given so that the patch of skin-whitening materials
The present invention relates to make the novel form of the cosmetic material of whiteness of skin, particularly percutaneous is given so that the patch of skin-whitening materials, what contain in this patch that one or more have a tyrosinase inhibitory activity makes skin-whitening materials as effective ingredient, and in during prolonging these active compounds is released on the skin.
Usually there is multiple factor can make skin darkening.One of them factor is melanic generation in the body, is that skin is exposed to the result that tryrosinase under the sunlight acts on tyrosine, and skin darkening is played a crucial role.
So far, for example ascorbic acid and derivant, kojic acid and derivant thereof, N-glucamine or hydroquinone and the blended cosmetic composition of derivant thereof have been used for treating skin darkening or facial wrinkles with having the active active compound of restraint of tyrosinase.Yet these routines are used for some problem of cosmetic composition of whiteness of skin.For example, the most frequently used reactive compound ascorbic acid is unstable in aqueous medium, contacts with air and is oxidized to hydroascorbic acid easily.Long term store also can overstrike.
For the stability of improving ascorbic acid had once been done many trials, for example, announced among the patent disclosure NO.Phyung 1-283208 of Japanese not substantive examination phosphate to be added in the ascorbic acid method that the reuse magnesium salt is transformed.Japan not substantive examination patent disclosure No.Phyung 1-228977,1-228978 and 1-228989 have narrated the method with fatty acid such as stearic acid or Palmic acid esterification ascorbic acid.
These methods can be improved the stability of ascorbic acid to a certain extent.Yet because ascorbic acid inherent instability, the low solubility in beauty treatment usefulness substrate and low absorbability of skin in aqueous medium, these chemical compounds fail to provide satisfied whiteness of skin effect.
The Japan not patent disclosure No.Sho 64-79105 of substantive examination has also proposed ascorbic acid is added in the facial film.But with the whiteness of skin effect that the facial film form obtains is unsatisfied.
In addition, also attempt oral have make whiteness of skin character reactive compound so that whiteness of skin.Yet this oral way is inappropriate because these reactive compounds before arrive desired area and present its effect in liver by metabolism, therefore can not take the reactive compound of high effective dose.
Like this, need provide a kind of new dosage form, can in the long time, give the skin-whitening materials that makes of high effective dose, and can not produce any stimulation skin.
In addition, the drug research person provides medical patch, and it can transfer heavy dose of medicine at the long period transdermal.For example Gale etc. has announced that in USP 4615699 transdermal that can transfer nitroglycerin (a kind of effective vasodilator) transfers system, and the transdermal amount is very high.Gale etc. have narrated in USP 4698062 and can carry out the therapy equipment that the pulsed transdermal transfers to bioactivator.USP 4738670 has announced the anti-inflammatory agent plaster, and it is made up of coat, bin-storing layer and the protective layer that can remove.
Yet the patch of the therapeutic purposes that relate in all these patents all designs for transdermal transfers medicine such as anti-inflammatory agent and vasodilator.Therefore, the present invention provides to contain the patch preparation that makes skin-whitening materials first.
The purpose of this invention is to provide a kind of novel form that is used to make the cosmetic material of whiteness of skin.
Another object of the present invention provides the patch that containing of a kind of percutaneous medication makes the material of whiteness of skin, and this class material can be controllably in a long time, with the percutaneous absorption of big effective dose ground.
Another object of the present invention provides that a kind of percutaneous is given so that the patch of skin-whitening materials, and this patch is by a coat, and a bin-storing layer and a protective layer that can remove are formed.
Another object of the present invention provides that a kind of percutaneous is given so that the patch of skin-whitening materials, and this patch is by a coat, a bin-storing layer, the film of a sustained release speed, and an adhesion coating and a protective layer that can remove are formed.
