5results about How to "Improve smearing" patented technology

The invention belongs to the technical field of cosmetics, and particularly relates to a cosmetic composition containing deoxyarbutin and a preparation method of the cosmetic composition. The cosmetic composition is prepared from the following raw materials in percentage by weight: 2%-5% of deoxyarbutin, 9%-20% of polyol, 0.7%-1.5% of a bacteriostatic agent, 50%-75% of nanocellulose hydrogel, 0-5% of a humectant, 0-1% of a thickening agent and the balance of deionized water. According to the invention, oxygenolysis of deoxyarbutin in water is prevented, the texture and the smearing feeling of cosmetics are remarkably improved, the cosmetics can be better attached to skin, the product action time is prolonged, and the action effect and the use comfort feeling are improved.

The invention discloses a fish scale collagen skincare composition, a fish scale collagen cosmetic and a preparation method of the fish scale collagen skincare composition and the fish scale collagen cosmetic. The fish scale collagen skincare composition comprises 0.05-0.5 part of fish scale collagen, 0.05-0.5 part of madecassoside and 0.5-3 parts of a purslane extract. According to the invention, the fish scale collagen, madecassoside and purslane extract are combined to repair the skin barrier, calm and relieve nerves, relieve skin inflammatory response and improve sensitive skin in multiple aspects from the aspects of sensitive skin characteristics, possible mechanisms and the like instead of treating head pain and foot pain. The fish scale collagen, madecassoside and purslane extract are derived from fish scales, centella asiatica and purslane of perches respectively, are gifts given to human beings by the nature, are green and healthy, and can endow the perches with high economic value, and through the simple synergistic effect of the three components and the extremely small component addition amount, the basic state of the skin of sensitive skin is consolidated, and the skin care effect is improved. The symptoms of itching, redness and the like after the sensitive skin is stimulated are relieved.

This invention discloses an integrated probe for air-induced ultraviolet fluorescence detection. A detachable snap-in filter (1) is installed at the light inlet of the front end of the cylindrical metal shield shell. A photomultiplier tube (2) is installed close to the back of the filter. A photomultiplier tube base (3) is set at the bottom of the photomultiplier tube (2). A photomultiplier tube base fixing plate (4) is set at the bottom of the photomultiplier tube base (3). The photomultiplier tube base fixing plate (4), the high voltage divider plate (7), the signal processing readout and power supply board (8), and the hollow fixing plate (9) are connected by support columns (6) and fixed with support column fixing screws (5) on both sides. This invention solves the technical problem that existing photon counting detection equipment is difficult to balance low cost, low noise, and compact structure in the application scenario of ultraviolet fluorescence remote sensing induced by radioactive nuclides in the air.

The present invention relates to a chitosan oligosaccharide chromatographic separation medium and a preparation method and application thereof. Styrene, divinylbenzene, sodium chloride, polyvinyl alcohol and n-butyl ether are dissolved in water and stirred to obtain a mixture A; a methylene blue aqueous solution is added to the mixture A to obtain a mixture B; an initiator is added to the mixture B to obtain a mixture C; the mixture C is subjected to a program heating and cooling reaction to obtain a polymer ball D having a core-shell structure; the polymer ball D is sulfonated to obtain a core-shell type strongly acidic ion exchange resin E; an acyl chloride reagent is added for reflux reaction to obtain a core-shell type sulfonyl chloride resin F; the core-shell type sulfonyl chloride resin F is added with aminocarboxylic acid for reflux reaction to obtain a chitosan oligosaccharide chromatographic separation medium. The material of the present invention is simple to prepare, the functional group is stable and not easy to lose, the separation efficiency is high, the one-time sample processing amount of the medium per unit volume is large, the cost is lower than that of the existing method, and it has important application value for the separation, purification and industrial production of chitosan oligosaccharides with a single degree of polymerization.
