4results about How to "Long-term storage stability" patented technology

A method for producing a dental filling material that includes polyvalent metallic element-including inorganic particles includes a step of treating the inorganic particles with a solution including a chelating agent.

This application relates to a nanodiamond radiation heat dissipation coating composition, its preparation method, and the product thereof. It belongs to the field of heat dissipation materials technology. The composition of this application uses silanization modification to solve the problem of nanodiamond agglomeration, resulting in uniform nanodiamond dispersion and long-term storage stability. It uses an organic-inorganic dual resin of silicon-modified polyurethane / inorganic siloxane protease, which balances adhesion, hardness, and temperature resistance, with a temperature resistance ≥600℃. The magma extract dispersant has three functions: dispersion, enhanced infrared radiation, and weather resistance. During spraying, surface drying at room temperature ≤5 minutes, complete curing ≤24 hours, insulation withstand voltage ≥4000V, and UV aging simulated life >10 years.

This invention belongs to the field of cosmetic technology and discloses a soothing and anti-hair loss hair growth liquid and its preparation method. The hair growth liquid is composed of a compound anti-hair loss active ingredient, a scalp soothing and repairing agent, a penetration enhancer, an alcohol solvent, a surfactant, a pH adjuster, a preservative, and water. The compound anti-hair loss active ingredient is obtained by gradient ethanol extraction and concentration of five raw materials, including Platycladus orientalis leaves and Drynaria fortunei, in a specific ratio. The scalp soothing and repairing agent is obtained by decoction and concentration of raw materials such as Salvia miltiorrhiza and Aralia elata root. During preparation, the final product is obtained through stepwise extraction, density control, specific sequential compounding, and low-temperature maturation processes. This invention, through the synergy of raw materials and processes, enables the product to have good effects in preventing hair loss, promoting hair growth, and soothing the scalp, and also exhibits good stability.

The invention provides a creatine kinase isoenzyme freeze-dried product as well as a preparation method and application thereof. The creatine kinase isoenzyme freeze-dried product is prepared from the following raw materials: a creatine kinase isoenzyme antigen, polygonatum polysaccharide and a chelating agent; the chelating agent comprises any one of citric acid, iminodiacetic acid and 1-hydroxyethylidene-1, 1-diphosphonic acid. The components such as the polygonatum polysaccharide and the chelating agent are adopted, so that double protection of oxidation resistance and dimer stability is realized, and the creatine kinase isoenzyme is good in activity after freeze-drying, stable in long-term storage and good in detection accuracy and repeatability.
