Hyaluronic acid skin care film, preparation method and application

Abstract

The invention relates to the technical field of hyaluronic acid, in particular to a hyaluronic acid skin care film. The hyaluronic acid skin care film is prepared from 12%-36% of hyaluronic acid or hyaluronate, 12%-30% of acetylated hyaluronic acid or acetylated hyaluronate, 12%-36% of hydrolyzed hyaluronic acid or hydrolyzed hyaluronate, 1%-30% of a moisturizer, 0-20% of an emollient, 0-20% of other active ingredients and 5%-15% of water. The hyaluronic acid and derivatives thereof are taken as main components of an instant soluble film, the mechanical property of the film is remarkably improved, the flexibility is enhanced, functions of a film forming agent, a thickening agent and a skin nutrition moisturizer and the like are integrated, and besides, the hyaluronic acid has an absorption promoting effect and a synergistic effect on the other added active ingredients; the product is small in size and convenient to carry and adopts a novel form.

Description

technical field [0001] The invention relates to the technical field of hyaluronic acid, in particular to a hyaluronic acid skin care film, and also relates to a preparation method and application of the hyaluronic acid skin care film. Background technique [0002] Instant film agents are usually composed of water-soluble film-forming materials, plasticizers, disintegrants, fillers, drugs, etc. Film-forming materials are the largest proportion of excipients in instant film formulations, accounting for more than 45% of the dry weight of film formulations. Among them, pullulan, gelatin and hypromellose are the most commonly used film-forming materials. Other commonly used film-forming materials include polycarbophil, cellulose derivatives, pullulan, xanthan gum, carob gum, guar gum, carrageenan, sodium alginate, chitosan, polyepoxy Ethylene, polyvinyl alcohol, etc. Different film-forming materials will significantly affect the mechanical properties and use experience of the f...

Problems solved by technology

[0010] In order to solve the problems of low hyaluronic acid content in hyaluronic acid film products in the prior art and complex system components, poor stability, and inconvenient transportation and carrying in emulsified composition products, this application provides a hyaluronic acid and Its derivative is the hyaluronic acid skin care film (hereinafter referred to as the care film or instant film) of the film-forming material. Hyaluronic acid is also a main nutritional active ingredient. It is necessary to add other active ingredients or drugs to give the instant film different skin care effects or the effect of treating diseases
