Abstract
The invention provides a kind of photochromic sunblock particles, a kind of human body surface coating comprising this photochromic sunblock particles is also provided, and the application of this coating on antitan agent, body painting, the hidden material in field.Human body surface coating of the present invention with the addition of photochromic material as ultraviolet absorber, and its absorbing wavelength is between 280-400nm, UVA and UVB is radiated the wave-length coverage on ground just, and absorption efficiency is high, improves UV resistance effect; Stable performance, life-span length, cold-resistant good in thermal property, and endurance can reach more than 10,000 times; This surface application thing, while absorption ultraviolet light, becomes beautiful gay colours of all kinds, when being applied in human body surface, irradiates in the sun, and meeting turn colors, for this characteristic, can be used as body painting, the hidden camouflage material in field etc.; In addition, by observing the situation of variable color and the depth of color, also can assess the intensity of solar ultraviolet, prompting people carry out certain ultraviolet protection.
Description
Technical field
The present invention relates to cosmetic field, be specifically related to a kind of human body surface coating.
Background technology
Ultraviolet belongs to Non-ionizing radiation in electromagnetic wave, the sun is ultraviolet main source, wave-length coverage is at 100-400nm, according to wavelength, ultraviolet is divided into again C section (UVC, 100-290nm), B section (UVB, 290-320nm) with A section (UVA, 320-400nm), ultraviolet is through atmosphere, in ozone layer, ozone molecule is less than 290nm(C section wavelength) ultraviolet all absorb, also absorb 290-320nm(B section in a large number) ultraviolet in scope, be radiated ground surface mainly 320-400nm(be mainly UVA) solar ultraviolet, can to people, biology etc. impacts.
But along with increasing the weight of of atmospheric pollution, ozone layer is day by day thin, the ultraviolet energy arriving ground constantly strengthens, cause the solar dermatitis in global range, the even obvious increase of skin carcinoma patient, one of sun-proof hot issue becoming cosmetic field, all kinds of sun-proof facial cream, the cosmetics such as emulsion constantly emerge, existing sun care preparations, the ultraviolet absorber generally selected is benzophenone, o-amino benzoyl ketone, salicylic acid esters, para-amino benzoic acid class, the organic compound such as cinnamate derivative, they only can shield a kind of ultraviolet (mainly UVB), and it is unstable, life-span is short, there is certain toxicity and zest, if addition is uncomfortable, chemical allergy can be produced, even skin carcinoma may be caused, in order to overcome this defect, Ge great cosmetics company constantly brings forth new ideas sun care preparations manufacturing technology in recent years, microcapsule technology is (as microsphere, polymer nanoparticle, solid lipid nanoparticle) safety and effect of Orangic sunscreen can be improved, improve its light stability in formula and the compatibility.This technology is constantly perfect, in recent years there have been developed capsule of nano method.
But current sun care preparations, the absorption for UVA is still seldom measured, and comprehensively cannot intercept the injury of ultraviolet to human body.Photochromic material, that a class can the organic compound of sensitization discoloration, its dominant absorption 280-400nm ultraviolet, just in time cover the wave-length coverage of UVA, be extraordinary UV absorbent, joined at present in the plastic foils such as PVC, solar irradiation is mapped on film, it absorbs ultraviolet color-changing, plays the effect of UV harms protection on the one hand, also reaches the object of conversion color, novelty attractive in appearance on the other hand.If by special processing technology, join in human body surface coating, such as, in all kinds of facial cream, emulsion, make-up paint, more excellent ultraviolet absorption effect will be produced.
Summary of the invention
The object of this invention is to provide a kind of ultraviolet absorption effect good, can beautiful, the safety and environmental protection of sensitization discoloration, color, can a kind of human body surface coating containing photochromic sunblock particles of UV harms protection.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of photochromic sunblock particles, comprise photochromic material and embedding medium, the concrete manufacture method of this photochromic sunblock particles is: be dissolved in by 2g photochromic material in 5.2g tetraethoxysilane, obtained mixed liquor under the effect of high speed shear emulsion dispersion, above-mentioned mixed liquor and 24g are contained the aqueous solution emulsifying of 1% hexadecyl trimethoxy ammonium chloride, the emulsion obtained is poured in the reactor of the sodium hydrate aqueous solution that the adjusted pH11.3 of 35g is housed, stirred at ambient temperature reacts 24 hours, centrifugalize product, use deionized water wash product, namely spraying dry obtains described photochromic sunblock particles.
Described photochromic sunblock particles also can be resuspended in the polyvinylpyrrolidone of 1%, obtains stable dispersion liquid, adds using in substrate.
The present invention also provides a kind of human body surface coating comprising this photochromic sunblock particles, and its preparation method is: photochromic sunblock particles adds in different substrates with weight ratio 5-10% ratio, mix homogeneously and get final product.
Described human body surface coating refers to paste, liquid cosmetics, skin care item, greasepaint, sunscreen product etc.
Described substrate is the basis making all kinds of cosmetics, is the compositions of oils and fats, surfactant, water etc.
The present invention also provides a kind of application comprising the human body surface coating of photochromic sunblock particles, and this coating is applied to antitan agent, body painting, the hidden camouflage material process in field.
Photochromic material of the present invention is can the compound of sensitization discoloration, mainly selects following six large classes:
