METHOD OF PREPARING ADDITIVE FOR SYNTHETIC DETERGENTS Russian patent published in 1998 - IPC

FIELD: synthetic detergents production. SUBSTANCE: invention relates to preparing detergent components of antiresorption additive based on carbohydrates and their derivatives, in particular, on carboxymethylcellulose sodium salt by way of mixing it with disperse component, in which use of ingredients in another aggregation state and use of other conditions of mixing ensures essential reduction in consumption of extremely scarce initial reagent (carboxymethylcellulose Na salt) and simultaneously increases antiresorption capability of additive giving rise to higher quality of detergent expressed in improved whiteness of washed cloth. The task is solved by mixing carboxymethylcellulose Na salt with disperse component in air-dry state at weight ratio 1:(5.5-30.0) and mixing energy 10-100 kJ/kg. As a result, carboxymethylcellulose salt consumption is reduced by 4.4 to 25.6 times. EFFECT: essentially reduced cost. 1 tbl
