Preparation method for film-forming liquid

Abstract

The invention relates to a preparation method for a film-forming liquid. A film-forming polymer solution is obtained by dissolving a film-forming polymer into a solvent, then an active substance is added into the solution, and the solution is stirred uniformly, so that the film-forming liquid is obtained. The film-forming liquid is prepared by blending the film-forming polymer and the active substance, and the preparation technology is simple and high in efficiency. The prepared film-forming liquid is usable as a sunscreen cream and realizes the effect of resisting radiation. The active substance can be absorbed by skin through pores, so that metabolism of tyrosine and tryptophan in amino acids is promoted, human body life is prolonged, and anti-stress capability and immunity of human body to external environment are enhanced, deposition of skin melanin is reduced, and thus black spots and freckles are reduced, and the film-forming liquid gives play to effects of whitening skin, retaining moisture and resisting oxidation, can be applied for a long time, and is convenient to clean, good in effect and low in cost.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a method for preparing a film-forming liquid. Background technique [0002] At present, when the skin is exposed to excessive ultraviolet rays outdoors, the epidermal cells will be damaged. Under strong ultraviolet radiation, it may also cause skin inflammation and burns. In severe cases, it may lead to pigmented skin cancer. Prevent the skin from being damaged by ultraviolet rays by rubbing sunscreen on the skin. The principle of sunscreen is to isolate the skin from ultraviolet rays, thereby preventing skin damage; It does not have sunscreen effect, and cannot moisturize, whiten, or resist oxidation on the skin; common chemical sunscreens usually contain harmful chemical components and heavy metal elements, which are prone to greasy feeling when used, and need to be reapplied frequently For a long time, it is easy to cause skin allergies, and in more serious cases, it ...
