Description

A kind of composite humectant and application thereof
Technical field
The present invention relates to cosmetic field, specifically composite humectant and application thereof.
Background technology
We are from biochemical viewpoint, the water content of skin moisture-keeping and skin, and effect and the epidermis of skin emollient keep the effect of moisture relevant.Under generic condition, when the water content of epidermis and its steaming pressure ratio surrounding height, moisture can be evaporated by skin surface and scatter and disappear; Under the condition of low humidity, or due to reasons such as lower layers of skin hydration deficiency and air flowings, cause the excessive dehydration of epidermis, skin just there will be xerosis shape.Only in drying, the skin surface of fragility applies one deck lipid material can not make epidermis soften, but exists even without lipid material, as long as skin re-starts hydration, and the softness that will become and flexible.Therefore think, in keratodermatitis, moisture maintains skin softness and elastic most important factor.
From physiological angle, the intercellular clayey of dry skin mesocuticle has defect.The pliability of skin is not only relevant with water content, and with skin contained by the quality of fat relevant.The diffusion of the barrier that lipid is formed controlled moisture turnover skin, lipid barrier is connected with keratin, and keratin makes water be combined with skin, contributes to scattering and disappearing of anti-sealing.Barrier action is physical action, depends on osmotic pressure and diffusion, i.e. humidity, cuticular thickness and integrity thereof.If skin barrier damages, transdermal moisture dissipation speed speeds.Epidermis is from basal layer, and between each layer, water content is in the trend reduced, and there is the concentration difference of water.When after the evaporation of outermost layer horny layer moisture, the moisture of internal layer, just to external diffusion, compensates the loss of cutin moisture.Hydrone may be dissolved in lipid, can permeate and by lipid layer, and this pattern can be described through scattering and disappearing (being called for short TEWL) of stratamocornium moisture preferably.
It is generally acknowledged that the mechanism of action of preserving moisture and protecting skin cosmetics can be divided into two kinds: one to be the oil film protective layer forming one deck closure at skin surface, reduce or stop moisture to evaporate from skin surface, making lower layers of skin diffuse to cuticular moisture and the further hydration of horny layer; Two is from air, absorb moisture make skin keep moistening, is better simply physical process, i.e. evaporation of water, diffusion and absorption.Wetting agent in cosmetics has water absorption, makes horny layer from top to bottom form steam gradient, supplements the loss that surface moisture evaporates to dry atmosphere environment.And some oils, directly can not make skin emolliency, be form closure oil film at skin surface, and horny layer softens indirectly, makes skin soft and moist.
In recent years, Elias proposes " fragment of brick-mud " model theory and explains cuticular labyrinth and function.
The main following a few class of wetting agent in cosmetics: polyalcohols wetting agent, hyaluronic acid wetting agent, lactic acid and sodium lactate, pyrrolidone sodium carboxylate, ceramide type wetting agent, amide-type wetting agent, glucose esters wetting agent, collagen protein class wetting agent, chitin derivative and chitosan etc.They are existing defects in some respects, such as: although the glycerol of the polyalcohols moisture absorbed in air reaches the effect of moisturizing, can not form the effect of protecting film and deep water supplement.The moisture retention of hyaluronic acid solution is embodied in the thin film forming viscoelasticity and has very strong water-retaining property (having water-retaining property as the hyaluronic acid in the intercellular matrix of skin conjunctive tissue), it is completely transparent, without remnant and greasy feeling, and have softness, the level and smooth sensation with lubricating.But it can not permeate the defect (even if the hyaluronic acid degradation thing of the short chain of 5 ~ 10 disaccharide units also not easily passs through horny layer of epidermis) of horny layer of epidermis.
Moisturizing mechanism due to skin suppresses moisture based on often being secreted the sebum film being coated on skin surface by sebaceous gland, through skin evaporation and the two kinds of effects being present in the water solublity hygroscopic component (being called nature moisturizing factor NMF) in horn cell.If Shortcomings in one aspect, will there will be and make xerosis cutis and coarse, the problem such as follow the string.
