74 results about "Sorbitan Sesquioleate" patented technology

Sorbitan sesquioleate. Sorbitan sesquioleate is derived from sorbitol, a humectant. Uses. This medication is used as a moisturizer to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations (e.g., diaper rash, skin burns from radiation therapy).

Preparation method for novel drug-loaded chitosan nano-microspheres

The present invention discloses a method for preparing drug-loaded chitosan nano-microspheres, wherein sorbitan sesquioleate is adopted as an emulsifying agent, vanillin is adopted as a cross-linking agent, and an emulsifying and cross-linking method is adopted. The method comprises: dissolving a certain amount of chitosan and a certain amount of 5-fluorouracil in a certain amount of an acetic acid solution with a mass fraction of 1%; after completely dissolving, slowly adding the resulting solution to a certain amount of a liquid paraffin oil phase, and rapidly stirring at a room temperature to form a white emulsus water-in-oil emulsion, wherein the resulting solution is adopted as the water phase, the liquid paraffin oil phase contains a certain amount of an emulsifying agent; adding a certain amount of a cross-linking agent solution to the reaction system, and continuously stirring for a certain time; carrying out centrifugal separation, collecting the prepared drug-loaded nano-microspheres, completely washing respectively by petroleum ether and acetone, carrying out freeze drying to obtain the yellowish drug-loaded chitosan nano-microsphere powder, wherein the particle size of the prepared drug-loaded chitosan nano-microspheres is 100-150 nm, the sphericity is good, the controlled release effect is good, the encapsulation efficiency is 90-96%, the drug loading rate is 20-25%, and the drug-loaded chitosan nano-microspheres can meet clinical oral requirements and injection requirements. In addition, the method has a simple process, and is applicable for the large-scale production.

BB Cream (Blemish Balm Cream) added with dense silica-coated pearl powder

The invention relates to a BB Cream (Blemish Balm Cream) added with dense silica-coated pearl powder, which is prepared by mixing, emulsification and homogenization of double-PEKG/PPKG-14/14 polydimethylsiloxane, sorbitan sesquioleate, dimethyl silicone polymer, cyclomethicone, isononyl isononanoate, titanium dioxide, dense silica-coated pearl powder, quaternary ammonium-18 bentonite, iron oxide, glycerol, butanediol, chlorine sodium, methyl hydroxybenzoate, propyl hydroxybenzoate, EDTA (Ethylene Diamine Tetraacetic Acid) disodium, algae extract, bis(hydroxymethyl) imidazolidinyl urea, essence and deionized water. Due to the adoption of the dense silica-coated pearl powder instead of mineral powder in the traditional BB Cream, the damage of directly added pearl powder to an emulsion system of cosmetics can be avoided. The BB Cream (Blemish Balm Cream) added with the dense silica-coated pearl powder is prepared by simple processes, not only can cover defects and has an isolation protection effect but also can nourish the skin with deep pearl nutrient contents and increase the skin elasticity, has a good whitening effect, and gives full play to a plurality of effects such as whitening, isolation, radioresistance and the like of the pearl powder.
