The invention relates to a melogabalin besylate patch as well as a preparation method and application thereof. The melogabalin besylate patch is prepared from the following raw materials in percentage by mass: 0.5 to 10 percent of melogabalin besylate, 25 to 40 percent of matrix, 0.1 to 1.5 percent of antioxidant, 0.05 to 0.15 percent of functional additive, 0.5 to 10 percent of cosolvent, 0.1 to 10 percent of transdermal enhancer, 36.5 to 48 percent of plasticizer and 13 to 32 percent of tackifier. On the basis of the total mass of the melogabalin besylate patch, the transdermal enhancer is prepared from the following components in percentage by mass: 0 to 2 percent of L-menthol and 0.5 to 1.5 percent of sucrose laurate; the antioxidant is butylated hydroxytoluene; the functional additive is chitosan oligosaccharide. The patch has good physical adhesion, and the release rate gt of the medicine after 24 hours; the cumulative permeation amount gt of the medicine after 24 hours; the medicine is convenient and safe to use, and the medicine effect is stable.

The invention discloses a scheelite combined collecting agent and a preparation method and application thereof, and belongs to the technical field of mineral processing. The combined collecting agent comprises the following components in percentage by mass: 2%-5% of sucrose laurate, 85%-92% of C16-C18 fatty acid salt and 6%-10% of hexamethyldisiloxane. The combined collecting agent is applied to flotation of scheelite, and efficient recovery of scheelite can be achieved through closed-loop flotation of one-time roughing, three-time refining and two-time sweeping. According to the combined collecting agent, the problem that a traditional fatty acid collecting agent is poor in solubility is solved, the combined collecting agent is simple in preparation process, good in collecting performance and selectivity, good in dispersity and solubility and good in environmental protection property, and the grade and the recovery rate of scheelite concentrate can be remarkably improved.

The present application provides a kind of whitening, improve skin barrier composition and its preparation method and application, it is related to skin care product technical field.The composition raw material includes: plant extract 30-42 parts, Lotus nut extract 13-17 parts, Beauveria extract 12-14 parts, malt oligosaccharide glucoside 1.2-1.6 parts, raspberry ketone glucoside 2-3 parts, oligopeptide 4-6 parts, sucrose laurate 1-2 parts, humectant 2-4 parts, thickening agent 1-1.8 parts, water 280-340 parts.The present application can inhibit tyrosinase activity by the synergistic effect of specific plant extract, Lotus nut extract, Beauveria extract, malt oligosaccharide glucoside, raspberry ketone glucoside, oligopeptide and other raw materials, achieve good whitening effect, and make each active ingredient transdermal absorption, protect skin keratin layer lipid bilayer structure from being destroyed, maintain the water-retention capacity of skin, avoid water loss, thereby play the role of improving skin barrier.

The invention discloses a method for improving the fermentation yield of human milk oligosaccharides, belongs to the technical field of human milk oligosaccharides, and solves the problems of how to optimize a fermentation process and realize effective synthesis of 2 '-FL by taking glucose and lactose as substrates due to the fact that a microbial whole-cell synthesis method of 2'-FL has the characteristics of mild conditions, low cost and the like and is the most common 2 '-FL synthesis method. Comprising the following steps: S1, transferring activated glycerol tube seeds into a slant culture dish for culture, and then inoculating the seeds into a seed shake flask for culture; s2, inoculating the seeds in the step S1 into a fermentation container for fermentation; s3, fermentation is conducted for 48 h, sucrose laurate is added, and fermentation is continued. In the later period of fermentation, the surfactant is added, so that the permeability of a cell membrane structure is improved, absorption of glucose and lactose and excretion of human milk oligosaccharide are promoted, the fermentation period is prolonged, the fermentation yield is increased, sucrose laurate has low toxicity and biodegradability, and the sucrose laurate has the advantages of being environmentally friendly and free of pollution. The pollution to the environment can be reduced, and the safety of the product can be ensured.
