[0004] Chinese patent 201410268341.7 discloses a whitening and moisturizing Tencel mask essence containing lecithin, which is composed of EDTA-2Na, lecithin / C12-16 alcohol / palmitic acid complex, glycerin, 1,3-propylene glycol, hyaluronic acid, hydroxyl Ethyl cellulose, etc. are used as raw materials, and the whitening and moisturizing essence containing lecithin is stored in the Tencel mask cloth. The prepared mask is more docile, soft, breathable and comfortable, and has better whitening and moisturizing effect, but the general mask cloth only carries Nutrient solution, its transdermal absorption effect is yet to be discussed
Although the emulsion uses a variety of surfactants, its stability is greater than the transdermal property, and it is only for the single substance salidroside, so the transdermal absorption is limited

Abstract

The invention discloses a moisturizing emulsion which is prepared from the following components: seaweed extract, hyaluronic acid, allantoin, vitamin E acetate, synthetic squalane, stearin, 1,3-butanediol, amino acid moisturizing agent, xanthan gum, carbomer, cetostearyl alcohol and cetearyl glucoside, essence, preservative and water. The raw materials of the moisturizing emulsion are easy to obtain, and the cost is low; by adding herbal plant extracts, the moisturizing emulsion is fresh and natural as well as comfortable and non-irritant and is not greasy; the moisturizing performance of the emulsion is excellent; the particle size of the emulsion is about 100nm, belonging to the scope of a micro-emulsion; and the molecular size of the moisturizing emulsion is farther less than that of other emulsions, so that the absorption to nutrient substances by the skin is facilitated and the transdermal absorption effect is good.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and in particular relates to a moisturizing emulsion and a preparation method thereof. Background technique [0002] Skin cells and tissues are prone to water loss, and the lack of water will lead to dry, dull skin, dandruff, and wrinkles. Moisturizing is an essential part of daily skin care. Professional hydrating and moisturizing cosmetics, which can deeply and effectively hydrate, nourish and moisturize the skin. [0003] Generally speaking, due to the lipids of the skin and the presence of the stratum corneum, hydrophilic molecules are difficult to be absorbed by the body through the skin barrier. The characteristics of the active substance molecule, such as molecular size and lipophilicity, the delivery vehicle, such as dosage form and penetration enhancer, and the tissue of the application site all affect the absorption effect of the skin.
