The solubility in organic solvents is superior to that in water. Chemicalbook is soluble in anhydrous methanol and ethanol solutions, as well as in organic solvents such as chlorinated hydrocarbons and ketones. It is soluble in water, and its aqueous solution has surface activity. After drying, it forms a film. After heating and cooling, it undergoes a reversible conversion from sol to gel. It can be used alone or in combination with other emulsifiers and stabilizers in cold drinks, with a maximum dosage of 1%. In recent years, it has been widely used in industries such as petrochemical, papermaking, leather, textile printing and dyeing, pharmaceuticals, food, cosmetics, etc., as dispersants, thickeners, adhesives, excipients, capsules, oil resistant coatings, and fillers.
