Sulfoethyl cellulose, also known as sodium carboxymethyl hydroxyethyl cellulose, is a water-soluble, non-ionic cellulose ether derivative. It is produced by reacting alkali cellulose with ethylene oxide and then sulfating the resulting product. This chemical is widely used in various industries, including pharmaceuticals, food, cosmetics, and oil drilling, due to its unique properties such as high viscosity, excellent film-forming ability, and stability in both acidic and alkaline environments. In pharmaceuticals, it serves as a binder, disintegrant, and viscosity-increasing agent, while in food, it acts as a stabilizer, thickener, and emulsifier. In cosmetics, it is used as a skin conditioning agent and in oil drilling as a drilling fluid additive. Its versatility and biocompatibility make sulfoethyl cellulose an essential component in many applications.
The CAS Registry Mumber 9032-46-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,3 and 2 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 9032-46: (6*9)+(5*0)+(4*3)+(3*2)+(2*4)+(1*6)=86 86 % 10 = 6 So 9032-46-6 is a valid CAS Registry Number.
