A kind of whitening cosmetic and preparation method thereof

Abstract

The invention discloses a whitening cosmetic and a preparation method thereof. The present invention uses a variety of plant compositions as main raw materials, mainly including rice bran extract, rhodiola rosea extract, ginkgo leaf extract, tea polyphenols, lemon juice concentrate, chitosan, kudzu root extract, konjac fine powder , sunflower disc extract, sunflower seed kernel extract, saponins kernel, hemicellulose, honey; in addition, it also contains a small amount of glycerin, 1,3-propylene glycol, squalane, sodium hyaluronate, carbomer, three Ethanolamine, Allantoin, Nano Titanium Dioxide, Collagen Powder, Antibacterial, Isooctyl Ferulate and Glutathione. The composition can be used in whitening formulations, and has the effects of whitening skin, moisturizing, antibacterial and anti-inflammation, eliminating free radicals, inhibiting melanin formation, and inhibiting the activities of dopachrome intermutation enzyme and tyrosinase.

Description

technical field [0001] The invention relates to the field of natural product utilization, in particular to a whitening cosmetic and a preparation method thereof. Background technique [0002] It is everyone's nature to pursue a beautiful appearance, and the condition and appearance of the skin is an important part of it. Healthy and fair skin is what everyone pursues. For this reason, the demand for whitening cosmetics has always been at the top of the demand for various cosmetics. At present, whitening products in the national daily chemical industry account for one-third. There are more than 3,800 daily chemical companies in my country. Each company has no less than 10 types of whitening products, and some even account for 80% of the products. Guangdong Province alone has More than 1,300 cosmetics manufacturers. [0003] Skin tissue is the first layer of human protective barrier, broadly divided into epidermis, dermis and subcutaneous tissue. The color of the skin is mai...

Problems solved by technology

[0010] (2) Product stability is low. Many anti-oxidant chemical functional ingredients of whitening cosmetics have one or several unsaturated double bonds. These functional ingredients can inhibit melanin in the skin due to their strong reduction , but when it is made into finished cosmetics, because it is exposed to the air for more than a month or even a few days, the unsaturated bonds are denatured and inactivated under the action of oxygen, light, metal ions, etc., and the whitening activity is lost, so that the whitening effect is relatively weak. Difference

[0011] (3) The whitening pathway is single, and melanin is produced through a series of complex chemical reactions, and there are multiple pathways to inhibit its production

However, various whitening additives can only inhibit one pathway, but fail to fully inhibit melanin.

[0012] (4) Existing whitening cosmetic products intentionally add a variety of chemical ingredients and use hormones in order to reflect the effect. Although they have a whitening effect on the skin and can reduce wrinkles, some cosmetic companies will add prohibited and restricted substances to their products ( such as antibiotics)

[0015] There are many whitening active ingredients that have been proven to have significant whitening effects, but due to various defects such as irritation and instability, the application and efficacy of the products are greatly limited
