CarboxyMethyl Cellulose (CMC) Detergent Grade
$0.01 Original price was: $0.01.$0.00Current price is: $0.00.
CarboxyMethyl Cellulose (CMC) Detergent Grade is a water-soluble polymer that is derived from cellulose, which is a naturally occurring polymer found in plant cell walls. CMC is produced by chemically modifying cellulose through the addition of carboxymethyl groups, which gives it its unique properties such as high water solubility, thickening ability, and film-forming properties.
CMC is widely used in a variety of industries, including food, pharmaceuticals, cosmetics, and textiles, as a thickener, binder, stabilizer, emulsifier, and dispersant. It is commonly found in food products such as ice cream, salad dressings, and baked goods as a thickener and emulsifier, as well as in cosmetics and personal care products such as toothpaste and shampoo as a binder and stabilizer.
