Problems solved by technology

There are many whitening products on the market, but these whitening ingredients are prone to oxidative discoloration and unstable performance, and high concentrations of whitening ingredients may also irritate the skin and affect the balance of the skin surface
[0003] Chinese invention patent CN201310414407.4 discloses a whitening liposome-coated microcapsule composition. By wrapping the whitening ingredients, the stability of the whitening ingredients is improved and the irritation is reduced. However, a surfactant is added in the preparation process, so that The product will produce a dry feel after use, and the skin feeling effect is not good
Chinese invention patent CN201910083518.9 discloses a freckle-removing, whitening and anti-aging cream, which increases the compatibility of whitening ingredients and other ingredients by adding liposome-encapsulated retinol, but the active ingredients can only react on the skin surface and are not easy to enter Skin base, so whitening, moisturizing effect is not good

Embodiment 1

[0042] A mild and high-efficiency whitening composition comprises, in parts by weight, 55 parts of glycerin, 5 parts of whitening agent, 13 parts of oil-soluble components, 20 parts of water and 6 parts of thickener.

[0043] The oil-soluble components include lecithin, hydrogenated phosphatidylcholine, cholest-5-en-3β-ol, α-tocopherol, sunflower seed oil, and the lecithin was purchased from Doosan Group, Korea, and the model is DS- SUN PC65; the hydrogenated phosphatidylcholine was purchased from Doosan Group, Korea, the model is DS-Soya HPC90; the cholest-5-en-3β-ol was purchased from Nippon Seika Co., Ltd.; the α-tocopherol was purchased from From the Royal DSM Company; the sunflower seed oil was purchased from the Hallstar Company of the United States, the brand name Sunflower Oil REF.

[0044] The weight ratio of cholest-5-en-3β-ol, α-tocopherol, and sunflower seed oil is 2:0.5:0.5.

[0045] The whitening agent is 4-butyl resorcinol, and the weight ratio of the lecithi...

Embodiment 2

[0055] A mild and efficient whitening composition and preparation method thereof, the specific steps are the same as those in Example 1, except that the weight ratio of the cholest-5-ene-3β-ol, α-tocopherol, and sunflower seed oil is 0.8: 1.2:1.5.

Embodiment 3

[0057] A mild and efficient whitening composition and preparation method thereof, the specific steps are the same as those in Example 1, except that the weight ratio of the lecithin, hydrogenated phosphatidylcholine and 4-butylresorcinol is 4:1: 8.

Abstract

The invention discloses a mild and efficient whitening composition which is prepared from the following raw materials in parts by weight: 50-80 parts of a water-soluble component, 5-10 parts of a whitening agent, 7.5-25 parts of an oil-soluble component and 10-30 parts of water. Through synergistic compounding of phospholipid, hydrogenated phosphatidylcholine and 4-butylresorcinol, the problems that 4-butylresorcinol is difficult to dissolve and easy to oxidize and discolor are solved, effective components are more easily absorbed by skin, the whitening and spot-fading effects are improved, and through adoption of cholest-5-ene-3 beta-alcohol, the whitening and spot-fading effects are improved. Through combination and compounding of 4-butylresorcinol, alpha-tocopherol and sunflower seed oil, irritation of 4-butylresorcinol to skin is reduced, the tenderness of a final product is greatly improved, meanwhile, through compounding of phospholipid, hydrogenated phosphatidylcholine and cholest-5-ene-3 beta-alcohol, the lipidosome has good stability, does not contain a surfactant, and is free of toxic and side effects. The use skin feeling of the product is greatly improved, and the skin is fine and smooth and not tight.

Description

technical field [0001] The invention relates to a mild and high-efficiency whitening composition, relates to A61K, and in particular relates to the field of cosmetic preparations. Background technique [0002] Whitening and freckle removal is an effect that beauty lovers have been pursuing. Skin darkening is due to the deposition of melanin produced by melanocytes into the skin. Whitening products achieve whitening effect by inhibiting the production of melanin. There are many whitening products on the market, but these whitening ingredients are prone to oxidative discoloration and unstable performance, and high concentrations of whitening ingredients may also irritate the skin and affect the balance of the skin surface.
