Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a pore-astringing composition film spraying agent and a preparation method thereof.

Background

The large pores in the face are common skin problems, mainly caused by the fact that sebaceous glands secrete vigorously, skin elasticity is reduced, and hair follicles are large. The inducing factors of pore enlargement include exogenous and endogenous factors, such as sex, genetic susceptibility, aging, chronic ultraviolet exposure, exogenous irritant substances, acne, seborrheic dermatitis and the like, the pore size is related to aging, the skin has reduced elasticity to cause skin integrity deterioration, and the appearance of the pores can be changed due to the relaxation of the support structure around the hair follicle. The size of the hair follicle volume is related to the size of the dermal papilla, and since dermal papilla cells express androgen receptors, they can be regulated by androgen, which becomes the main factor affecting the size of the hair follicle and thus the size of the pore.

Various treatment methods related to the large facial pores are available, and mainly include photoelectric device treatment (for example, a non-peeling dot matrix laser device is generally considered to be capable of effectively improving the large facial pores), chemical skin-changing operation and the like. The methods all can achieve certain effects, but have defects and application limitations. However, most of the existing cosmetic products with the pores converging are in the form of films such as cotton sheets and facial masks or in the mode of matching emulsion and cosmetic cotton, the action duration is short, after long-term storage, due to gravity factors, the functional components of the cotton sheets or the facial masks cannot be completely attached to the carrier, and the product effect is greatly reduced. The mode of using the emulsion and the cosmetic cotton together is very easy to be polluted by the outside and the clothes due to repeated use, and the use is very inconvenient.

The spray film agent is used as a new dosage form, combines the advantages of film agents and spray patch, is prepared into spray, and is sprayed on the surface of skin to form a layer of soluble biological film, so that the retention time on the surface of the skin is prolonged, the drug effect is improved, other dressings are omitted, and the effects of isolating and killing pathogenic microorganisms and the like are achieved through a brand new dual antibacterial mechanism of physics and biology.

At present, the film forming agent is mostly focused on the application of antibiosis or skin trauma, and is rarely used in cosmetics, and the current film forming agent materials are mostly glycerol, ethanol, tween or polyvinylpyrrolidone and the like, so that the film forming time is long, the brittleness of the film is high, the stretching force is insufficient, and the product is inconvenient to use. Patent document CN103550248A discloses a bacterial cellulose/chitosan composite film spraying agent, which uses N-methylmorpholine as a solvent and has irritation to skin and mucous membrane. Patent document CN107638570A discloses a chitosan/ethyl cellulose long-acting film spraying agent with pharmacological activity, which is added with a large amount of auxiliary materials, and has the advantages of complex process, strong skin irritation, easy occurrence of agglomeration phenomenon and poor product stability.

The skin stratum corneum which is normal in metabolism has about 10 to 15 layers, and the uppermost layer can continuously fall off to make room for the newly-grown cells which are pushed upwards. However, due to the influence of factors such as poor external environmental conditions, unbalanced drinking and eating, abnormal daily work and rest, night stay, smoking, drinking, emotion and the like, modern people often slow down the metabolism speed and show skin problems such as large pores, oily light, darkness and the like, the abnormal metabolism causes that keratinocytes cannot naturally fall off and are thickly accumulated on the surface, and lactic acid and sodium lactate are selectively added in the formula aiming at the characteristic of thick horny layer of the large pores to achieve a certain effect of helping the exfoliation of the horny layer; meanwhile, the pH value of the formula can be adjusted, and the stable faintly acid is maintained, so that the skin can be recovered to be normal; while lactic acid and sodium lactate are good humectants.

In addition, the film spraying agent is added with skin conditioners such as FOMES OFFICINALIS extract, palmitoyl tripeptide-5, 10-hydroxydecanoic acid, sebacic acid, 1, 10-decanediol, royal jelly and the like, so that the problem of excessive secretion of skin grease is effectively solved, and the effect of astringing pores is achieved.
