Embodiment 1

[0027] Hydrolyzed pearl powder flexible nano liposome composition:

[0028] Soy Lecithin 5.5wt%

[0029] Sodium cholate 1.5wt%

[0030] Hydrolyzed pearl powder 1.5wt%.

[0031] The preparation method of hydrolyzed pearl powder flexible nano-liposome is realized through the following steps:

[0032] (1) Quantitatively weigh soybean lecithin, sodium cholate, and hydrolyzed pearl powder and dissolve them in chloroform;

[0033] (2) Water bath at 37.5°C, remove chloroform under reduced pressure;

[0034] (3) vacuumize and store for 5h;

[0035] (4) Add isotonic phosphate buffer (pH7.4), hydrate and then rotate on a rotary evaporator for 1 hour to remove the organic solvent, forming a hydrolyzed pearl powder flexible liposome suspension;

[0036] (5) The liposome suspension was placed in an ice-water bath, subjected to probe-type intermittent ultrasound for 30 minutes, and then filtered with a 0.2 μm filter head to obtain flexible nanoliposomes of hydrolyzed pearl powder.

Abstract

The invention provides a moisturizing and repairing lotion containing hydrolyzed pearl essence flexible nano-liposomes and sea buckthron oil. The lotion is prepared through emulsification and homogenizing of hydrolyzed pearl essence flexible nano-liposomes, sea buckthron oil, hyaluronic acid, an emulgator, a moisturizing agent, a stabilizer and deionized water. The lotion can effectively enhance the metabolism of skin epithelial cells and dermis and repair skin, and flexible nano-liposomes can penetrate through the human skin surface easily to make pearl essence fused with cells so as to become effective. Sea buckthron oil and hyaluronic acid which have great moisturizing and repairing functions are also added, and can moisturize keratinocytes deeply and improve the elasticity of skin dermis through intense hydration, the resistance of skin is improved, skin is tightened, and fine wrinkles are reduced. The lotion is natural, mild and nearly free of irritation, is suitable for long-term use so as to achieve skin barrier repairing, moisturize skin and make skin younger, has good moisturizing and repairing effects on dry skin and sensitive skin, and can effectively whiten skin and resist wrinkles and aging.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and relates to a skin care product, in particular to a seabuckthorn oil moisturizing and repairing milk containing hydrolyzed pearl powder flexible nano-liposomes, which can solve the problem of dull skin, decreased elasticity, dryness and aging. Problems, liposome skin care products with good moisturizing and repairing effects. Background technique [0002] Skin consists of epidermis, dermis, subcutaneous fat and appendages. The epidermis is the outermost layer of the skin and is divided from inside to outside: basal cell layer, acanthocyte layer, granule cell layer, clear cell layer and keratinocyte layer. Skin appendages include hair, hair follicles, sebaceous glands, and sweat glands. The skin absorbs external substances mainly through three ways, namely the stratum corneum, pilosebaceous glands and sweat duct orifices. Among them, the stratum corneum is the most important way for the sk...
