Embodiment 1

[0034] Dissolve 1.5 grams of trehalose, 0.2 grams of hyaluronic acid, 0.2 grams of Tween, and 0.03 grams of ethylparaben in 98 grams of water, and set aside. Dissolve 0.5 g of lecithin and 0.05 g of vitamin E in part of ethanol, then slowly inject into the standby solution of trehalose and hyaluronic acid stirred at 50°C, and stir until the ethanol is completely volatilized to obtain trehalose and hyaluronic acid lipids Body fluid, the liposome fluid can be directly used in cosmetics, and can also be processed by drying and other methods to obtain trehalose and hyaluronic acid liposome powder, and then used in cosmetics.

Embodiment 2

[0036] Weigh 0.30 g of Span 20, 1.05 g of Tween 20, 0.20 g of lecithin, 1.80 g of propylene glycol, and 0.37 g of isopropanol palmitate, mix well, and slowly add 95 g of purified water under stirring, then Add 1.00 g of trehalose and 0.10 g of hyaluronic acid and stir to obtain trehalose and hyaluronic acid microemulsion, which can be directly used in cosmetics.

Embodiment 3

[0038] Weigh 0.20 g of trehalose and 0.02 g of hyaluronic acid and dissolve them in 5 ml of water. After emulsifying this solution with 20 ml of dichloromethane solution of glycolic acid copolymer at high speed, add it to 100 g of purified water containing 1 g of Tween , stirring to remove dichloromethane, after the microspheres are solidified, filter, wash, and dry to obtain trehalose and hyaluronic acid microspheres, which can be directly used in cosmetics.

Abstract

A composition for cosmetics to clean, nurse and beautify the skin, hair and nails is prepared from trehalase, hyaluronic acid and other raw materials for cosmetics.

Description

Technical field: [0001] The invention relates to a composition containing trehalose (English: trehalose) and hyaluronic acid (English: hyaluronic acid, also known as hyaluronic acid) that can be used in cosmetics and a preparation method thereof, belonging to the technical field of cosmetics. Background technique: [0002] Skin and its derived appendages (including hair, nails, etc.) are important organs of the human body and play an important role in the health and fitness of the human body. However, harsh environments such as dryness and freezing seriously threaten the quality of the skin, affecting the normal metabolism of the skin and the health of the human body. For example, if the human body loses 10% of water, it will threaten life and health, and if it loses 20%, it will cause death; if the skin has a lot of water, it will appear plump and stretched, otherwise it will appear dry and old, with poor elasticity. However, the skin is most prone to lack of water, which ...
