Problems solved by technology

In the case of ensuring 95% cell survival, deoxyarbutin has the best inhibitory effect on tyrosinase activity, which is 10 times that of hydroquinone, 38.5 times that of α-arbutin, and 350 times that of β-arbutin. And the safe concentration is more than 4 times higher than that of hydroquinone, but deoxyarbutin is easy to decompose under light conditions

preparation example Construction

[0092] The preparation method of the above-mentioned liposome with whitening and freckle-removing function comprises the following steps:

[0093] 1) Mix sodium hyaluronate, hydrolyzed collagen and water at 60-70°C to obtain a buffer solution;

[0094] 2) Take a part of the buffer solution, add compound whitening and freckle-removing ingredients, and mix evenly at 40-50°C to obtain the content liquid;

[0095] 3) mixing soybean lecithin and oil evenly at 40-50°C, then evaporating to dryness under reduced pressure to obtain a phospholipid film;

[0096] 4) Take a part of the phospholipid film, add the content liquid, and use the supercritical fluid reverse evaporation method to obtain a monolayer-wrapped liposome;

[0097] 5) Take a part of the buffer solution to disperse the liposomes wrapped in a single layer, add a part of the phospholipid film, and use the film extrusion method to obtain the liposomes wrapped in a double layer, and then repeat the operation to obtain the l...

Abstract

The invention discloses a lipoid with skin-whitening and freckle-removing functions as well as a skin-care product composition. The lipoid has multiple phospholipid bimolecular layer and is prepared from the following raw materials in percentage by weight: 10 to 40 percent of compound whitening and freckle-removing component, 10 to 25 percent of soyabean lecithin, 0.1 to 5 percent of sodium hyaluronate, 0.1 to 5 percent of hydrolyzed collagen, 0.1 to 5 percent of grease and the balance of water. The lipoid is added in the skin-care product composition. The lipoid and the skin-care product composition have good skin-whitening and freckle-removing effects and is favorable for improving the elasticity of skin and the water content of cuticle; and the preparation process is simple and suitablefor industrialized large-scale production.

Description

technical field [0001] The invention relates to a liposome and a skin care product composition with the function of whitening and removing spots. Background technique [0002] Skin is composed of three layers of epidermis, dermis and subcutaneous tissue. The epidermis is the outermost layer of the skin, and can be divided into five layers from the outside to the inside: stratum corneum, transparent layer, granular layer, spinous layer and basal layer. The stratum corneum is located in the outermost layer of the epidermis and is composed of 4 to 8 layers of flat anucleated cells; the transparent layer is composed of 2 to 4 layers of flat anucleated cells; the granular layer is composed of 2 to 4 layers of spindle or rhomboid cells; the spinous layer is composed of 4 to 8 layers of polygonal cells; the basal layer is located in the deepest part of the epidermis and is composed of a single layer of cylindrical cells. Melanocytes, also known as dendritic cells, are mainly loca...
