Embodiment 1-5
[0032]
[0033]
[0034] Among the above raw materials, water is deionized water or water for injection.
[0035] Embodiments 1-5 are implemented through the following steps.
[0036] ① Disperse hydroxyethyl cellulose in the mixture of glycerin and butanediol evenly, add pentylene glycol, stir evenly, add 80% water in the system, and heat to 80-90°C. Then add sodium PCA, sodium acrylic acid / MA copolymer, caprylyl glycol, and 1,6-hexanediol, dissolve completely to obtain the material of phase A, and keep it warm at 80-90°C for later use;
[0037] ② Add purslane extract, lotus leaf extract, tea extract, guava leaf extract, Korean angelica extract, hydroxyphenylpropionamide benzoic acid, ceramide 3, and dipotassium glycyrrhizinate to the system 10% in the water, stir evenly to obtain the B-phase material;
[0038] ③Insulate the material of phase A at 80-90°C for 90 minutes, then start to cool down. After cooling down to 60°C, add the material of phase B and stir for 10 mi...

Abstract
The invention discloses a skin moisturizing and repairing composition and a preparation method thereof. The composition includes water, butanediol, glycerin, 1,2-pentanediol, sodium PCA, purslane extract, lotus leaf extract, tea leaf extract, guava leaf extract, Angelica gigas root extract, phenoxyethanol, a sodium salt of an acrylic acid / MA copolymer, hydroxyethyl cellulose, caprylyl glycol, 1,6-hexanediol, nicotinamide, hydroxyphenylpropionamidobenzoic acid, ceramide 3, dipotassium glycyrrhizinate and sodium hyaluronate. The invention also provides the preparation method of the skin moisturizing and repairing composition. The composition has a good product stability, can penetrate into deep skins, has a good moisturizing effect on the skins, also can remove excessive free radicals and promote skin barrier recovery, and can be used for the daily care of various types of skins, especially the protection and care of sensitive skins.
Description
technical field [0001] The invention relates to a composite preparation, in particular to a skin moisturizing and repairing composition and a preparation method thereof, belonging to the fields of pharmaceuticals, fine chemicals and personal care products. [0002] technical background [0003] The skin is the largest organ of the human body, and its total weight accounts for 5% to 15% of the body weight. It has two barrier functions: on the one hand, it prevents the loss of water, electrolytes, and other substances in the body; on the other hand, it prevents the invasion of harmful substances from the outside. . Moisture content is an important indicator of skin health. The moisture content of the skin of the elderly is only 75% of that of the young, so moisturizing the moisture content of the skin can improve the living environment of skin cells, promote metabolism, increase circulation, and achieve the purpose of delaying aging and moisturizing the skin. [0004] In rece...
