Hydroxyethylcellulose (HEC) is a synthetic polymer that is used in a variety of industries for a variety of purposes. It is a non-ionic, water-soluble polymer that is derived from cellulose, and is used as a thickening agent, emulsifier, stabilizer, and suspending agent.
HEC is manufactured by a variety of companies, including Dow Chemical, BASF, Ashland, AkzoNobel, and Clariant. Dow Chemical is one of the largest manufacturers of HEC, and produces a variety of grades of HEC, including the Dowfax and Natrosol brands. BASF produces the Cellosize brand of HEC, while Ashland produces the Aqualon brand. AkzoNobel produces the Aqualon and Aquasol brands of HEC, and Clariant produces the Mowiol brand.
Each of these companies produces a variety of grades of HEC, which differ in terms of molecular weight, viscosity, and other properties. The molecular weight of HEC can range from 100,000 to 1,000,000, and the viscosity can range from 1 to 10,000 cps. The grades of HEC produced by each company also vary in terms of their solubility, stability, and compatibility with other ingredients.
In addition to the major manufacturers of HEC, there are also a number of smaller companies that produce HEC. These companies include Lubrizol, and Kima Chemical . Each of these companies produces a variety of grades of HEC, which differ in terms of their properties.
Overall, there are a variety of companies that produce HEC, and each company produces a variety of grades of HEC. The grades of HEC produced by each company vary in terms of their molecular weight, viscosity, solubility, stability, and compatibility with other ingredients.
