The invention relates to a method for preparing a nano-cellulose antibacterial composite material through on-line culture. The method comprises the following steps of: (1) inoculating an activated bacterial cellulose producing strain into a liquid culture medium, performing amplification culture, transferring the liquid culture medium into a bioreactor, culturing, adding an antibacterial material into the liquid culture medium, and continuing to culture to obtain an unpurified antibacterial bacterial cellulose composite material; and (2) peeling a bacterial cellulose membrane from a framework or directly soaking the composite material in a NaOH solution, treating in water bath, and washing until an obtained product is neutral to obtain the nano-cellulose antibacterial composite material. The preparation efficiency is high, and the method is simple, convenient, feasible and low in cost; and the surface of the bacterial cellulose composite material has a nanoscale three-dimensional fibrous mesh-shaped structure, the tensile strength of the material is greatly improved compared with that of a pure bacterial cellulose membrane, and the material can be widely applied to products such as facial masks, wound dressings, plasters, artificial skins and the like.

Preparation method of layer-by-layer self-assembled hollow fiber forward osmosis membrane

The invention discloses a preparation method of a layer-by-layer self-assembled hollow fiber forward osmosis membrane. The preparation method comprises the steps of: preparing hollow fiber forward osmosis base film, modifying hollow fiber ultrafiltration base film, repeating layer-by-layer assembly of polycation and polyanion layers, performing interface cross-linking polymerization for preparinga selective functional layer, conducting moisturizing, and carrying out treatment and storage so as to prepare the layer-by-layer self-assembled hollow fiber forward osmosis membrane. The surface of the hollow fiber self-support base film which is prepared by using a phase conversion method is activated firstly, layer-by-layer assembly of polycation and polyanion is repeated on the surface of thefilm so as to form an functional polarization layer for an electrolyte solution, and the polyamide selective layer is prepared through interfacial chemical cross-linking polymerization. The prepared hollow fiber forward osmosis membrane has a controllable thickness and an internal polarization layer with a high charge capacity, and the internal concentration polarization phenomenon can be alleviated effectively during the forward osmosis process; therefore, the hollow fiber forward osmosis membrane can simultaneously obtain high flux and low reverse salt flux, has high filtration separation efficiency, easy cleaning and a long service life, and can be widely applied to seawater desalination and concentration and desalination of brine.

Freeze-dried powder, solvent and application of freeze-dried powder and solvent

The invention belongs to the technical field of cosmetics, and particularly discloses a freeze-dried powder containing a stem cell supernate and micro-molecule polypeptide, a solvent containing a transdermal penetration enhancer and a cosmetic set containing the freeze-dried powder and the solvent. According to the prepared freeze-dried powder, the stem cell supernate and the micro-molecule polypeptide are compounded, so that the stem cell supernate and the micro-molecule polypeptide exert a synergistic effect, and the prepared freeze-dried powder has the functions of significantly delaying aging, reducing fine wrinkles, moisturizing and tendering the skin and the like; the solvent used for dissolving the freeze-dried powder specifically contains the transdermal penetration enhancer, the situation is promoted that active components of cell factors, micro-molecule polypeptide and the like in the freeze-dried powder permeate into the dermis through the transdermal penetration enhancer, and therefore the skin protection effect of the solvent is further improved. According to the freeze-dried powder, the solvent and the cosmetic set, the freeze-dried powder and the solvent are individually packaged, the quality guaranteeing period of the cosmetic set is prolonged, no preservative is added into the freeze-dried powder, and it is effectively ensured that the active components in the freeze-dried powder are not influenced.

Multi-moisturizing double-layer makeup remover and preparation method thereof

The invention provides a multi-moisturizing double-layer makeup remover. The multi-moisturizing double-layer makeup remover is characterized by being prepared from, by weight, 20%-35% of grease, 1%-15% of alcohol moisturizer, 0.25%-2.5% of sugar moisturizer, 0.01%-0.25% of macromolecular moisturizer, 5%-20% of surfactant, 0.25%-2.5% of natural moisturizing factors (NMF), 0.1%-0.6% of preservative, 0.1%-0.4% of anti-allergic agent and the balance deionized water. The double-layer makeup remover greatly integrates cleansing oil and cleansing water and adopts an oil-water separation structure, the bottom layer is water, and the upper layer is oil. Before the makeup remover is used, the makeup remover is needed to be shaken to be uniform, the water-oil proportion is adjusted to reach the state that the makeup remover is non-irritant to the skin, the advantage of string makeup removing capability of the cleansing oil is played, and a mild and non-irritant effect is also achieved. In addition, the composite moisturizing system formed by four different types of moisturizing components serves as a whole, the defect that single moisturizing components are not comprehensive and not remarkable in effect is greatly overcome. Furthermore, the invention further provides a preparation method of the multi-moisturizing double-layer makeup remover.
