Problems solved by technology

[0006] At present, the whitening ingredients that are widely used in the market can be simply divided into synthetic and plant-extracted ingredients according to their sources. These two categories of whitening ingredients have their own advantages and disadvantages. Synthetic ingredients are generally low in cost and cheap. The compatibility of ingredients is good, but the disadvantage is that the efficacy is relatively single and the scope of efficacy is narrow, while plant extracts are natural ingredients, safe, and contain a variety of similar structures, so that they can play their functions from multiple angles and in multiple ways. to a good synergistic effect, but its disadvantage is that the cost is far more than synthetic ingredients

Embodiment 1

[0023] The whitening composition of the present invention includes component A, component B, component C, and component D, wherein the total weight percentage of the composition contains: component A mulberry bark extract 10%, chamomile extract (endothelium antagonistic Agent) 10%, Rhodiola rosea extract 10%, grape seed extract 10%, licorice extract 8%, chicken mulberry extract 5%; component B: arbutin 9%, kojic acid dipalmitate 5 %, Nicotinamide 3%, Tetrahydrocurcumin 2%; C component 27.6% 1,3-butanediol solution, D component preservative Zema 0.2%, and methyl paraben 0.2%.

[0024] The invention adopts chicken mulberry extract, mulberry bark extract and kojic acid dipalmitate to directly modify and modify tyrosinase, so that it loses its effect on melanin precursor tyrosine, thereby inhibiting melanin The purpose of formation: Arbutin uses tyrosine analogues to compete with tyrosine for tyrosinase, effectively inhibiting the formation of melanin; licorice extract inhibits and i...

Embodiment 2

[0027] The whitening composition of the present invention includes component A, component B, component C, and component D, wherein the total weight percentage of the composition contains: component A mulberry bark extract 7%, chamomile extract (endothelium antagonistic Agent) 7%, Rhodiola rosea extract 8%, grape seed extract 8%, licorice extract 7%, chicken mulberry extract 3%; component B: arbutin 7%, kojic acid dipalmitate 3 %, Nicotinamide 2%, Tetrahydrocurcumin 1%; C component 1,3-butanediol 46.6%, D component preservative Jema 0.2%, and methyl paraben 0.2%.

Embodiment 3

[0029] The whitening composition of the present invention includes component A, component B, component C, and component D, wherein the total weight percentage of the composition contains: A component Morus alba extract 8.5%, chamomile extract (endothelium antagonistic Agent) 8.5%, rhodiola extract 8.5%, grape seed extract 8.5%, licorice extract 10%, chicken mulberry extract 4%; component B: arbutin 8%, kojic acid dipalmitate 4 %, nicotinamide 2.5%, tetrahydrocurcumin 1.5%; C component 1,3-butanediol 35.6%, D component preservative Jema 0.2%, and methyl paraben 0.2%.

[0030] The preparation method of the whitening component of the present invention has specific steps: 1) When 1,3-butanediol in component C is heated to 50°C-60°C, kojic acid dipalmitate in component B is uniformly dissolved completely, After adding D component preservative methyl paraben to dissolve evenly, when the solution is reduced to 30℃, add B component arbutin, nicotinamide, and tetrahydrocurcumin in sequenc...

Abstract

The invention discloses a skin whitening composition which comprises a white mulberry root-bark extract, a chamomile extract, a rhodiola rosea extract, a grape seed extract, a licorice extract, a morus australis extract, arbutin, kojic acid dipalmitate, nicotinamide, tetrahydrodiferuloylmethane, a moisturizer and a preservative. The effective skin whitening ingredients of the skin whitening composition can inhibit the activity of tyrosinase, can block the transportation of melanin and can inhibit the formation of melanin; the skin whitening composition can be applied to skin whitening cosmetics and is safe and effective.

Description

1. Technical Field [0001] The present invention relates to a skin whitening composition, which has an excellent skin whitening effect without causing any side effects, and includes various plant extracts and composites. 2. Background technology: [0002] People are increasingly pursuing healthy and fair skin, making the demand for whitening compositions increasing. Skin tissue is the first protective barrier of human beings. It is broadly divided into three parts: epidermis, dermis and subcutaneous tissue. The color of the skin is mainly determined by the amount, size and distribution of melanin contained in skin cells. There are two aspects to skin whitening, one is intracellular whitening, and the other is cell whitening. [0003] For intracellular whitening, we should first prevent melanin synthesis. In this regard, there are more studies on inhibiting tyrosinase activity. Tyrosinase is a kind of polyphenolase, belonging to the class of oxidoreductases, which can catalyze the...
