METHOD OF MODIFYING SURFACTANT PROPERTIES Russian patent published in 2012 - IPC C11D11/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of producing detergents and cleaners and more specifically to methods of producing surfactants. The method of modifying surfactant properties involves adding ultrafine carbon particles with size from 2 to 200 nm and effective specific surface area of not less than 700 m²/g to a saturated solution or concentrate of the surfactant. The weight content of ultrafine carbon particles in the obtained mixture ranges from 0.3 to 10%. The obtained mixture is stirred until complete saturation of the ultrafine carbon particles with the saturated solution or concentrate of the surfactant. After mixing the mixture of ultrafine carbon particles with the surfactant, the mixture is heated to temperature lower than the boiling point of the mixture. Heating is carried out for not less than 30 minutes, followed by filtration, drying and vacuum treatment of the obtained product.

EFFECT: invention increases surface activity and penetrating power of a surfactant with minimal expenses, high cleaning efficiency of the surfactant, simple process of modifying surfactant properties.
