Abstract

The use of brighteners of formula wherein R and R1, which can be the same or different from each other, are each -H, CH3, -CH2CH3, -CH2-CH2OH; X is the cation of sodium, potassium, ammonium, an amine or an alkanolamine residue, in the brightener of some kinds of detergent products.
The presence of the brighteners of formula (I) satisfactorily solves the problem of increasing the whiteness degree of the paste, or, in the case of a powder detergent, of the granules obtained after atomization.
