Description
Technical field
The present invention relates to the preparation method of a kind of hypertonicity oiliness raw material used for cosmetic, belong to polyolefin field in synthetic oil.Described invention comprises the preparation of catalyzer, the preparation method of hypertonicity oiliness raw material used for cosmetic.
Background technology
The Transdermal absorption of makeup refers to that the effective constituent of makeup accumulates in not same-action skin layer by Cutaneous permeation and plays the process of various function, and the main barrier of osmotic absorption comes from stratum corneum.The shielding effect of keratoderma make the infiltration rate of a large amount of nutritive ingredients of the oiliness raw material in skin care product and interpolation and infiltration capacity minimum, had a strong impact on Transdermal absorption effect.The problem such as common skin infections and " skin oxidative ", mainly because skin surface makeup nutritive ingredient is superfluous, provides hotbed to parasitic bacteria breeding and causes.Although mineral oil and paraffin can make skin seem smooth in a short time, due to its osmotic absorption and poor air permeability, can cause on long terms skin greasing, unglazed, coarse, even acne, foxiness, macula, casting skin, wrinkle, even to dewater decortication.Therefore, mineral oil base-material being added in makeup while bringing skin care, also to bringing various injury in various degree, constraining its application in the cosmetics of super quality.Therefore, only have the performance of the Transdermal absorption promoting makeup, the overall performance of cosmetics series just can be improved accordingly, finally could reach maximum effect with minimum addition, thus benefit.
At present, adding penetration enhancer is solve the short permeating method the most general that cosmetic actives absorbs a difficult problem, and conventional osmotic absorption promotor has azone, oleic acid, Phospholipase C, lemon extract wet goods.Percutaneous absorption enhancer contributes to the obstacle that effective constituent overcomes keratoderma, the barrier action of change keratoderma that can be reversible, and do not damage any active cells, reach and increase makeup and the medicine solubleness at skin, make the object that the specific absorption of effective constituent and speed increase.But the effect of penetration enhancer is temporary transient, after taking out, skin can recover normal barrier function, therefore finds and improves aobvious very important of oil binder that makeup easily absorb.
Hydrogenated polyalphaolefins is a kind of pure saturated hydrocarbon compound, aromatic free and other group, therefore from toxicology and allergology angle be nontoxic, safe green, nonirritant, touch-safe.Research shows: the oiliness raw material that molecular weight is little is easily spread in the maximum barrier stratum corneum absorbed by the lipid bilayer diffusion in intercellular substance, and velocity of diffusion is larger more inward.Therefore, it is applied to skin surface and can infiltrates diameter that skin surface is covered with fast and absorbed about the pore of 60 nm and stratum corneum greatly because of mean diameter young pathbreaker for the hydrogenated polyalphaolefins of small-molecular-weight, thus the activeconstituents being wrapped by delivery can be made to be carried to epidermis deep layer until play a role in dermal tissue, overcome mineral oil to spread upon on skin and make cosmetic actives be difficult to enter dermal tissue and the absorbed difficult problem of subcutis by pore, simultaneously, hydrogenated polyalphaolefins also shows moistening, moisturizing, soft and moist, smooth, do not block pore, without greasy feeling, do not cause acne, anti-ageing characteristic of waiting for a long time, very excellent to the nutrition moisturizing effect of skin.Particularly to use it in personal care product (as makeup remover, emulsion, clean, frost, essential oil, lipstick, baby oil, hair products base oil) there is great using value.
Summary of the invention
The object of the invention is, provide the preparation method of a kind of hypertonicity oiliness raw material used for cosmetic.The ionic liquid catalyst systems activity of this system is high, repeatability is strong, cost is low, simultaneously, hydrogenated polyvinyl used for cosmetic prepared by the method not only has colourless, tasteless, odorless, safety, nontoxic, the performance such as non-stimulated, simultaneously, because the 3-D solid structure of the hyperbranched approximate sphericity of its uniqueness and molecular diameter are less than Nano grade 6 ~ 7 number magnitude characteristic, and show the Thief zone more superior than hydrogenated polyalphaolefins, high moisturizing lock water, highly air-permeable, do not block the effect such as pore and slowly-releasing, the oil binder product be well suited for as makeup/makeup uses.
