Description

skin care gel with synergistic whitening effect and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to skin-care gels with a synergistic whitening effect and a preparation method thereof.

Background

East asian women were beautiful with white from ancient times, and many methods such as milk bath and the like were used for whitening. Even many toxic substances, such as the early lead and mercury facings, were used until the last century. Many whitening agents have been developed and selected since the recent years.

Currently, , the most effective skin lightening active, is hydroquinone, however, hydroquinone has a small molecular weight, destroys melanocytes, and may induce inflammation, and therefore, hydroquinone is subject to strict regulations in most countries throughout the world and is banned from use as a cosmetic ingredient.

Rhododendrol was once the whitening active mastered by the japanese famous cosmetics company however, there was a later outbreak of over-whitening problem the company's patent was regrouped with the customer for this problem.

Azelaic acid is a naturally occurring medium chain length fatty acid which is an important skin lightening agent with tyrosinase inhibiting effect, however, there are technical and formulation problems in application firstly azelaic acid must be effective at high concentrations where it does not dissolve making formulated cosmetic quality poor, especially very thick systems difficult to wipe.

L-ascorbic acid and its derivatives and licorice extract are easy to discolor, and its stability is not a little problem, and special attention is required for use.

Moreover, in order to make a short-term profit, some illegal merchants add glucocorticoid to cosmetics such as facial masks, which can produce whitening and firming effects in a short term, but have very serious consequences on human skin after long-term use.

The skin color is controlled by various factors, but mainly depends on the content and distribution of melanin, melanin is produced by melanocyte, which is important constituent cells of skin and is in the form of dendriform, melanin formed in cells is transported into stratum corneum cells through the dendriform, the dendriform forms epidermal units with keratinocytes in a ratio of 1: 36, exists in the epidermal basal layer, and the melanocyte determines the skin color by synthesizing melanin and can absorb ultraviolet rays so as to prevent the body from being damaged by the ultraviolet rays.

Recently, many companies developed whitening compositions, and more than products with simple additive effects are difficult to achieve the expected effects, so how to develop a high-efficiency, safe and stable whitening scheme with synergy becomes difficult points in the cosmetic industry.

Disclosure of Invention

In order to overcome the technical defects, of the present invention is to provide skin care gels with synergistic whitening effects, which not only can inhibit tyrosinase activity and melanin transfer to achieve the purpose of whitening, but also can act synergistically in other aspects to achieve the outstanding whitening effect and simultaneously achieve balanced cooperation without negative feedback.

In order to solve the problems, the invention is realized according to the following technical scheme:

skin care gel with synergistic whitening effect, which comprises the following components in percentage by mass:

wherein the whitening complex 1 comprises water, butylene glycol, arbutin, citric acid, sodium sulfite, acetyl tyrosine, strawberry saxifrage extract, peony root extract, aminopropanol ascorbic acid phosphate, scutellaria root extract, glutathione, hydrolyzed cherry plum;

the whitening compound 2 comprises glycerin, butylene glycol, extract of bearberry (Arctostaphylylos UVA URSI) leaf, extract of Psidium guajava (MITARCARPUS SCABER), sodium metabisulfite, and biotin.

Nicotinamide has outstanding effects in inhibiting melanosome transfer and accelerating damaged DNA repair. When the content of the nicotinamide in the skin care gel is lower than 1%, the overall whitening effect is greatly weakened through tests; when the nicotinamide content is more than 3%, the cytotoxicity is too high through in vitro cell tests. Therefore, the content of nicotinamide is 1-3%.

The citrus peel extract in the skin care gel disclosed by the invention has the effect of coordinating with other components to enable the skin to be smoother and brighter, and the total flavone content and the types of the citrus peel extract are standards of the quality of the citrus peel extract, the citrus peel extract in the skin care gel disclosed by the invention adopts a carbon dioxide supercritical extraction technology, the total flavone content of the citrus peel extract extracted by the technology can be more than 2.5%, is obviously higher than that extracted by other modes, and has the advantages of environmental friendliness and energy conservation.

Arbutin has the ability to inhibit the activity of tyrosinase, a key enzyme in the process of melanin production, and also has the effect of absorbing ultraviolet rays. Because arbutin has similarity with tyrosine in structure, the arbutin can compete with tyrosine to bind tyrosinase in the process of synthesizing melanin by tyrosine, thereby reducing the effect of tyrosinase on synthesizing melanin. In the test of the skin care gel of the present invention, when the content of arbutin is less than 0.1%, the whitening effect is very small; when the arbutin content is more than 0.5 percent, the skin care gel of the invention is easy to turn red in the storage process. Therefore, the content of arbutin is 0.1-0.5%.

In the whitening compound 1, arbutin and scutellaria root extracts can absorb ultraviolet rays; radix Scutellariae extract and radix moutan extract can inhibit inflammatory factor activity; arbutin can inhibit tyrosinase activity; the extract of herba Saxifragae, radix Scutellariae extract, and ascorbic acid phosphate aminopropanol can inhibit natural oxidative polymerization of melanin and reduce melanin formation; the extract of herba Saxifragae can repair DNA damage caused by ultraviolet; glutathione can promote the synthesis of pheomelanin but not eumelanin; acetyl tyrosine is able to compete with tyrosine for tyrosinase; the aminopropanol ascorbic acid phosphate and citric acid can promote cell proliferation and keratinocyte renewal; hydrolyzed cherry plum can inhibit melanin from being engulfed by keratinocyte. Through research and experimental analysis on the mechanism, in the skin care gel, when the dosage of the whitening compound 1 is less than 1%, the whitening effect of the skin care gel is not obvious; when the whitening complex 1 is used in an amount higher than 4%, the heat-resistant and light-resistant stability of the skin care gel of the present invention is deteriorated. Thus, the selective amount of whitening complex 1 is 1-4%.

In the whitening compound 2, the extract of the malpighia glabra contains hydrogenated quinine derivatives, and is compounded with the extract of the bearberry leaves, so that the malpighia glabra has a powerful inhibitory effect on the neuraminidase. In the skin care gel, when the dosage of the whitening compound 2 is less than 0.5%, the skin care gel has a non-obvious whitening effect; when the whitening complex 2 is used in an amount of more than 5%, the heat-resistant and light-resistant stability of the skin care gel of the present invention is deteriorated. Therefore, the selective amount of whitening complex 2 is 0.5-5%.
