Colorless Liquid Polyethylene Glycol PEG CAS 25322-68-3 Dispersants Lubricants Overview Polyethylene glycol is a polymer which is hydrolyzed by ethylene oxide. It has no toxicity and irritation. It is widely used in various pharmaceutical preparations. The toxicity of low molecular weight polyethylene glycol is relatively large. In general, the toxicity of diols is very low. Topical application of polyethylene glycol, especially mucosal drug, can cause irritant pain. In

White Powder Carbomer 980 CAS 54182-57-9 High-molecular Polymer Overview Carbomer 980 is a polyolefin. It can be viewed as polyethylene with carboxylic acid (CO2H) substituents on alternating carbons. Owing to these groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral). For this reason, acrylic acid exists in atactic, syndiotactic, and isotactic forms, although this aspect is rarely discussed. The polymerization is initiated with radicals and

Anionic Surfactants N-Hexadecyltrimethylammonium Chloride CAS 112-02-7 Protein Flocculation And Water Treatment Flocculation Disinfectant Introduction: Cetrimonium chloride, also known as hexadecyltrimethylammonium chloride, is a white crystalline powder. It is easily soluble in isopropyl alcohol and water. It produces a lot of foam when shaken. It has good compatibility with cationic, nonionic and amphoteric surfactants. It has good chemical stability and is resistant to

Surfactants Tetradecyl Trimethyl Ammonium Chloride CAS 4574-04-3 Catalyst Emulsifier Disinfectant Bactericide Antistatic Agent Introduction: Alkyl trimethyl ammonium salt type cationic surfactants are prepared by reacting higher fatty amines with methyl chloride in the presence of sodium hydroxide. This type of surfactant has a structure of a long-chain alkyl or hydrocarbon group (usually 8 to 22 carbon atoms) and three short-chain alkyl groups (1 to 7 carbon atoms), such as
