Description of key information
Small amounts ofCorfree® M1 which are soluble in mutual solvents or alcohol blends was used to increase and improve fluid viscosity and/or reduce, lower or prevent fluid loss for aqueous fluids gelled with visco-elastic surfactants. Particularly suitable particles include, but are not necessarily limited to, solid, particulate dicarboxylic acids that are insoluble in both aqueous and hydrocarbon liquids, but which are soluble in mutual solvents or alcoholic blends. Particularly suitable dicarboxylic acids include, but are not necessarily limited to, dodecanedioic acid, undecanedioic acid, sebacic (decanedioic) acid, azelaic acid, suberic acid and mixtures.
Key value for chemical safety assessment
Additional information
Corfree® M1 is soluble in mutual organic solvents or alcohol blends. The method of measurement is not given.
