Solid sunscreen described in natural polymer described in step (a), step (b) as previously mentioned.
In step (a), described aqueous solution refers to the solution that acid is formed with water, alkali and water, salt and water or polymer and water, and wherein the quality of water accounts for the 50%-99.9% of aqueous solution quality, is preferably 75-99.5%, is more preferably 85-99%.Described acid is mineral acid or its mixture such as the organic acid such as acetic acid, citric acid or phosphoric acid, hydrochloric acid, sulphuric acid, and described alkali is sodium hydroxide, potassium hydroxide, ammonia or its mixture.Described salt is for containing Na
+, K
+, Mg
2+, Ca
2+, Zn
2+, NH
4 +deng and water-soluble salt under normal temperature and pressure state, as sodium chloride, potassium chloride, sodium sulfate, calcium chloride etc.
As is known to the person skilled in the art, according to natural polymer dissolubility and concentration, suitable temperature can be chosen, add acid or alkali, shearing force, make it be dissolved in the water.Such as deacetylated chitosan can be dissolved in the water under pH is less than the normal temperature condition of 4, needs to add acetic acid when dissolving; Low solubility agarose can be dissolved in water at about 80 DEG C; Agar dissolves under needing the temperature more than 100 DEG C; Cellulose needs just can be dissolved in water under low temperature, highly basic, Strong shear power condition, also needs to add highly basic in course of dissolution, and as sodium hydroxide solution, after certain hour is freezing, high speed machine stirs again; During dissolution of high-concentration cellulose solution, required shearing force is larger than low concentration solution, and dissolution of high-concentration agarose solution is temperature required higher than low concentration agarose solution.
The solid sunscreen be wrapped by can be liquid in preparation process, if butyl methoxydibenzoylmethise melting when high temperature (more than 95 DEG C) is liquid, also can be solid particle state, as zinc oxide, titania nanoparticles.
In preparation process, also can liquid sunscreen together be joined in the solution that step (a) obtains with solid sunscreen (preferably after melting), obtain the microcapsule simultaneously wrapping up solid sunscreen and liquid sunscreen.Liquid sunscreen is various liquid sunscreen known in the art, as ethylhexyl methoxy cinnamate (OMC), 2-cyano group-3,3-diphenyl 2-Propenoic acid-2-ethylhexyl ester etc.
In described step (b), organic solvent can be added, as ethanol, isopropyl alcohol, methanol, acetone, silicone oil, liquid paraffin, olive oil, Oleum Cocois, Oleum Ricini, hardened soybean oil or its combination etc. in the solution that described step (a) obtains.Surfactant can be added if Tween is (as Tween20 in the solution that described step (a) obtains, Tween40, Tween60, Tween80 etc.), Triton (as TX-100), SDS, CTAB, SDBS, sodium alkyl sulfate, polyoxyethylene ether is (as PO-500, PO-310), alkylglycoside, cithrol, sorbitan sesquioleate (as Arlacel83), polyoxyethylene hydrogenated Oleum Ricini, sorbitan trioleate (as Span85), sorbitan monooleate (as Span80), anhydrous sorbitol tristearate (as Span65), or its combination, promote sunscreen dispersion.Also can add stabilizing agent in the solution that described step (a) obtains as polyvinyl alcohol, Polyethylene Glycol, polyvinylpyrrolidone, gelatin, xanthan gum, hydroxypropyl cellulose, phosphate, polyphosphate or its combination, promote sunscreen dispersion.Such as, when sunscreen is butyl methoxydibenzoylmethise, surfactant Tween20, Tween80 and TX-100 can be added, be distributed under the condition of high speed shear in agarose solution and form O/W emulsion; For solid-state sunscreen, as titania nanoparticles, surfactant can be added as polyoxyethylene ether, cithrol etc., under the condition of high speed shear, first be distributed to cellulose aqueous solution be mixed to form S (solid)/W (water) dispersion liquid.Sunscreen be liquid and solid mixture time, surfactant and stabilizing agent can be added simultaneously and dispersible in chitosan-acetic acid solution form S/O/W dispersion liquid as ethylhexyl methoxy cinnamate and Zinc oxide nanoparticle mixture add Tween20 and PEG-10000.The dispersion effect that also can reach in conjunction with dispersing modes such as ultrasonic, grindings.Organic solvent, surfactant, stabilizing agent or its consumption combined are the 0-50wt% of S/W dispersion liquid or O/W emulsion gross weight, and preferably, being 0.5-40wt%, is more preferably 5-35wt%.
Oil phase described in step (c) be in preparation process for liquid, be insoluble to solution that step (a) formed and adding the solution formed with step (a) under lipophilic surfactant condition and can be formed the compound of emulsion, can be silicone oil, liquid paraffin, olive oil, Oleum Cocois, Oleum Ricini, hardened soy bean wet goods country allow to use in cosmetics and be grease or its combination of liquid at the operational.In oil phase consumption and step (b), S/W dispersion liquid or O/W emulsion consumption mass ratio are 1:10-10:1, if mass ratio is too little, microcapsule diameter is difficult to control; If mass ratio is too large, microcapsule productive rate is too low.
Lipophilic surfactant described in step (c) is dissolved in used oil phase, can be selected from sorbitan sesquioleate (as Arlacel83), polyoxyethylene ether (as PO-500, PO-310), polyoxyethylene hydrogenated Oleum Ricini, sorbitan trioleate (as Span85), sorbitan monooleate (as Span80), anhydrous sorbitol tristearate (as Span65), alkylglycoside, cithrol etc.In oil phase, lipophilic surfactant consumption is the 0.5-10wt% of oil phase, if consumption, is difficult to control microcapsule diameter very little; If consumption is too many, the control of particle diameter is not improved.
According to the stability of polymer solution, the temperature of corresponding set-up procedure (c).As when polymer be agar and agarose time, the temperature of step (c) is 40 DEG C-100 DEG C; When polymer is cellulose, the temperature of step (c) is-10 DEG C-40 DEG C.In addition, step (c) is prepared in S/W/O emulsion or O/W/O emulsion process except adding aqueous phase, oil phase, surfactant, the compound making emulsion-stabilizing can also be added, as stabilizing agents such as polyvinyl alcohol, Polyethylene Glycol, polyvinylpyrrolidone, gelatin, xanthan gum, hydroxypropyl cellulose, phosphate, polyphosphates.Wherein, aqueous phase refers to the described S/W dispersion liquid that step (b) obtains or O/W emulsion.
In step (d), S/W/O emulsion or O/W/O emulsion solidify to form the condition of granule can depending on natural polymer dissolution properties.For the polymer of high-temperature digestion low-temperature setting, as agar, agarose, solidification that the S/W/O emulsion formed as embedded material or O/W/O emulsion (can be less than 40 DEG C of even ice baths) at a lower temperature.The S/W/O emulsion that the cellulose dissolved for low temperature, highly basic, Strong shear power condition is formed as embedded material or O/W/O emulsion can be solidified under the condition of room temperature, acid adding.In addition, cross-linking agent can be added in step (d), microencapsulated material is solidified under the process conditions of suitable control, as microencapsulated material be chitosan time, aldehydes, hexandial, glutaraldehyde etc. can be added, or phosphoric acid salt, tripolyphosphate, four Quadrafos etc. shorten the hardening time of chitosan.
