A non-pyrogenic preparation containing nanoparticles synthesized by magnetotactic bacteria for medical or cosmetic applications. The nanoparticles are constituted by a crystallized mineral central part including predominantly an iron oxide, as well as a surrounding coating without material from the magnetotactic bacteria.

The invention refers to novel dermatic and cosmetic compositions to protect against impaired pigmentation of the skin. Locally caring Ginkgoloides are selected out of pure, high quality products comprising phospholipids and lecithins to antagonize alkyl-acyl GPC. The Ginkgoloides are bound to one or more transport proteins, carrier proteins, peptides, amino acids and these carriers contain at least one acetyl group and/or Acetyl CoA. The entire transdermal compositions then endocrinologically equilibrate the skin and the skin cells whereby acetylating compounds locally act as sun screening agent.

The multi-lamellar gel emulsion includes about 0.5 wt % to about 4.0 wt % of cosmetically acceptable emulsifying fats, a cosmetically acceptable non-ionic surfactant, a water-soluble suspending polymer, and at least 80 wt % of water.

The present invention provides a solid mask and a preparation method thereof. The solid mask includes a hydrophobic substrate layer and a nanofiber layer, the nanofiber layer has a three-dimensional structure and is electro-spun onto the hydrophobic substrate layer through uniaxial electrostatic spinning technology, and the nanofiber layer is prepared by the following food-grade raw materials in parts by mass: 10 to 30 parts of gelatin, 1 to 30 parts of soya bean lecithin and 0.1 to 10 parts of a functional substance. The present invention provides a solid mask, using gelatin and soya bean lecithin as the framework. The nanofiber layer is a three-dimensional laminate made of fibers having a diameter of a few hundred nanometers. The nanofiber layer has a membrane structure similar to the extracellular matrix. The raw materials of the solid mask are all food-grade raw materials or natural extracts.

The invention relates to the process for producing an microemulsion system of nano essential oil, the process comprising the following steps: (i) preparing a dispersed phase of essential oil; (ii) preparing of a carrier formed from a mixture of diethylene glycol monoethyl ether and lecithin; (iii) adding the carrier to the dispersed phase while keeping the dispersed phase temperature between 60 and 100° C. after addition of the carrier, while simultaneously stirring under vacuum; then pass the entire solution mixture through the system of high-pressure homogeneous machine integrated dispersion nozzle; (iv) adding the solution mixture obtained in step (iii) to Capryol 90 while keeping the mixture temperature between 60 and 100° C., and stirring at a rate ranging from 400 up to 800 rpm under vacuum; (v) cooling the mixture, homogenizing the mixture by ultrasonication to achieve a droplet size smaller than 100 n.

The present disclosure relates to an emulsified liposome composition and a method for preparing the emulsified liposome composition. The emulsified liposome composition includes a lecithin, wherein the lecithin includes a phosphatidylcholine, and the amount of the phosphatidylcholine in the lecithin is 25% to 40%.
