This invention discloses a supported anti-sulfurization reducing agent and its preparation method, relating to the technical field of rubber additives. A supported anti-sulfurization reducing agent includes an adhesive layer and an inner capsule. The adhesive layer is formed by blending a carrier rubber and a fatty acid salt. The inner capsule includes a core material and an inner capsule wall. The core material is the anti-sulfurization reducing agent, while the inner capsule wall is formed by reacting and curing an amino-modified liquid isoprene rubber and a urea-formaldehyde prepolymer. This application, by using microencapsulation, prepares an anti-sulfurization reducing agent with a double-layered supported structure. This not only effectively improves the problems of poor compatibility and difficult dispersion of pure anti-sulfurization reducing agents in rubber compounds, but also effectively protects the active ingredients, which is beneficial for improving the actual utilization rate of the anti-sulfurization reducing agent, reducing the amount of anti-sulfurization reducing agent added, and thus reducing the production cost of rubber products.

The invention relates to an artemisia apiacea-containing penetration enhancing composition with skin cell repairing and relieving effects, and a preparation method and application thereof, and belongs to the technical field of cosmetics. The research finds that the anti-inflammatory effect generated by only inhibiting an upstream anti-inflammatory path of an NF-kappa B channel is limited, and the anti-inflammatory effect can be remarkably enhanced by blocking a downstream conduction chain while inhibiting the NF-kappa B channel. On the basis, through the artemisia apiacea extract and the flos magnoliae extract, an upstream anti-inflammatory path is inhibited, recruitment and infiltration of inflammatory cells are reduced, a downstream conduction chain is blocked, and the anti-inflammatory effect is synergistically improved. Besides, through cooperation of the oat kernel oil, the jasmine flower oil and the squalane, on one hand, the solubility of fat-soluble active matter is improved, on the other hand, the composition can participate in repairing, stabilizing and optimizing the lipid structure of the skin cuticle, synchronously open the skin fat-soluble channel and convey the active matter more efficiently, and therefore the excellent relieving, repairing and stabilizing effects are achieved.

This application relates to the fields of biotechnology and agricultural waste resource utilization technology, specifically disclosing a solid-state fermentation agent for livestock and poultry manure used as feed for black soldier fly larvae and its application. The fermentation agent comprises lactic acid bacteria, yeast, Bacillus subtilis, cellulase, protease, β-glucanase, nutrient carrier, complex enzyme activator, trace element additives, and antioxidants. The preparation method involves: pre-activating the bacterial strains and preparing a culture medium; mixing the solid components with the culture medium; performing two-stage solid-state fermentation; drying and pulverizing; and finally granulation, coating, and secondary drying. This fermentation agent can be used to treat livestock and poultry manure. Adding it at a ratio of 1-5% and fermenting it at room temperature with regular turning converts the manure into black soldier fly feed. It has the advantages of efficiently degrading organic matter in manure and reducing harmful residues. The preparation method is stable, ensures the activity of the fermentation agent, and is simple to operate, facilitating large-scale production.

The present application relates to a skin cell soothing and repairing composition containing artemisia and its preparation method and application, and belongs to the technical field of cosmetics. The present application finds that only by inhibiting the upstream anti-inflammatory pathway of the NF-kappa B pathway, the anti-inflammatory effect is limited, while inhibiting the NF-kappa B pathway, the downstream transmission chain is blocked, and the anti-inflammatory effect is significantly enhanced.
