Embodiment Construction

[0029] In order to illustrate the central idea of ​​the present invention expressed in the column of the above-mentioned summary of the invention, it is expressed in specific embodiments. Various components in the embodiments are drawn in proportions suitable for illustration rather than actual components, and are described first.

[0030] The applicant's previously approved Taiwan No. I313177 patent provides a method for extracting a mixture containing tyrosinase inhibitors from lemon peel: take fresh lemon peel, chop it, and then add propylene glycol to mix it. The mixing ratio is: add 100-1000ml of propylene glycol per 100g of crushed lemon peel. The mixed solution is fully mixed, treated with ultrasonic waves for 1 to 59 seconds to break the cell wall, then sterilized by microwave irradiation, and then the mixed solution is centrifuged, and the upper layer is obtained as the tyrosine-containing enzyme inhibitor of the present invention. Whitening mixture. If 100g of crus...

Abstract

The invention discloses a whitening composition containing a tyrosinase inhibitor which comprises 0.1%-2.5% of tyrosinase inhibitors CitrusC, 0.1%-2.5% of vitamin C glucosides (Ascorbic Acid 2-Glucoside) and 0.1%-2.5% of Tranexamic Acid (Tranexamic Acid) by weight. The above components interact in cooperation to enhance skin whitening.

Description

technical field [0001] The present invention relates to a cosmetic, more specifically, a whitening composition containing a tyrosinase inhibitor, which can inhibit the action of tyrosinase to prevent its spontaneous polymerization in the skin Melanin is formed. Background technique [0002] Not only in hot summer, but in all seasons of the year, whitening has always been the most popular topic among Asian women. According to A.C.Nielsen's research report, Taiwanese women's love for whitening is the second highest in the world, second only to South Korea. [0003] see figure 1 It has been shown that the synthesis of melanin in melanosomes depends on the catalysis of various enzymes, one of the most important enzymes being tyrosinase. Tyrosinase first hydroxylates tyrosine to L-3,4-dihydroxyphenylalanine (Duba; L-dopa). DOPA is quickly converted to dopaquinone. Dubaquinone is a watershed intermediate product in the process of melanin formation. When cysteine ​​(cysteine)...
