Problems solved by technology

The second type is glycerin-based water-based film, which is low in price, convenient to use, and good in safety; the disadvantage is that its water absorption and long-term moisturizing ability are only average
The third category is ordinary emulsion film, which contains ingredients such as oil and moisturizer, which can adjust the feeling of use and the ability to moisturize; it needs to be improved because it has no sebum film composition and no melting point similar to the sebum film. Poor compatibility with skin

Abstract

The invention relates to a skin protection film composition and a preparation method thereof. The skin protection film composition comprises the following components in parts by weight: 100 parts of phase A materials including ceteareth-12, myristyl myristate, glyceryl stearate, cetostearyl alcohol and potassium cetyl phosphate, phase B materials including water, glycerol, sodium hyaluronate, EDTAdisodium, betaine, hydroxypropyl guar gum / xanthan gum and lactic acid, phase C materials including sodium benzoate and gardenia extract, and phase D materials including chlorphenesin, ethylhexylglycerin, phenoxyethanol and 1,2-hexanediol. According to the skin protection film composition and the preparation method thereof, the skin protection film composition has the components similar to those of a skin lipid film, the melting point of lipid particles is 32-34 DEG C, and a layer of protection film capable of reducing transdermal water loss and resisting external invasion can be formed on theskin.

Description

technical field [0001] The invention relates to the technical field of skin protection films, in particular to a skin protection film composition and a preparation method thereof. Background technique [0002] The skin contains a lot of water, protein, sugar, lipids, electrolytes and vitamins, among which skin lipids play an important role in skin barrier, moisturizing and skin condition. Sebum is secreted by cortical cells belonging to the holocrine glands. The composition of sebum is relatively complex, mainly containing wax lipids, triglycerides, free fatty acids, and also mixed with phospholipids and cholesterol lipids produced after epithelial cell metabolism. Usually the pH of the skin is 4.5-6.5, and the weak acid can inhibit the reproduction of pyogenic bacteria and white tinea fungus that often exist on the skin surface, making it difficult to develop, thus having a bactericidal effect and achieving the purification effect of the skin itself. Skin surface lipids a...
