White crystal powder without any visible foreign matters. Soluble in water, slightly soluted in alcohol, dissolvable in benzene, ether and petroleum ether etc., Esters will be formed by reaction with common organic acid; No reaction take place when it is heated with dilute caustic solution. application Pentaerythritol is used in the manufacture of Alkyd resins, fatty acid rosin and tall oil esters and to make paint and coatings, printing ink, coating adhesives, explosives, sealants, varnish, lacquer, vinyl chloride, synthetic rubber and miscellaneous including Pentaerythritol tetranitrate (PETN), urethane coatings, flame retardant paints, polyvinyl chloride stabilizers, olefins antioxidant and Pentaerythritol triacrylate.
Application of nitrocellulose Nitrocellulose, also known as cellulose nitrate or nitrocellulose, is an organic polymer compound with the chemical formula (C6H7N3O11) n. It is the product of the esterification reaction between cellulose and nitrate, usually in the form of white or slightly yellow cotton fluff, insoluble in water, but soluble in organic solvents such as esters and acetone Nitrocellulose, also known as cellulose nitrate ester, abbreviated as NC, commonly known as nitrocellulose, is the product of the reaction between cellulose and nitrate. Nitrocellulose made from cotton fibers is called nitrocellulose. Nitrocellulose is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis, and various oils. Different degrees of polymerization result in different strengths, but they are all thermoplastic substances. Easy to change color under sunlight and highly flammable. Attention should be paid to safety in production, processing, packaging, storage, transportation, sales, and use.

Application 1.Glycerol monocaprylate is a pure plant-derived glycerol fatty acid ester (medium carbon chain). It has good multi-functional properties such as emulsifying, dispersing, anti-corrosion, moisturizing and stabilization. It is safe, gentle and easy to use. It is a multifunctional moisturizer, fatliquor and preservative. 2. Mainly used as auxiliary emulsifier, emollient, moisturizer, natural preservative in cosmetics (such as cream, lotion, microemulsion, etc.). It can effectively maintain oil and water stability. It is a natural, efficient and safe preservative with better corrosion resistance than glycerol monolaurate.
