Abstract (en)
[origin: ES8205902A1] The invention relates to formulations which are stable to metal ions and contain a stilbene fluorescent whitening agent which is substituted by sulfo groups, and an acid phosphoric acid ester of an oxyalkylated fatty amine of the formula < IMAGE > wherein R is an aliphatic hydrocarbon radical of 8 to 22 carbon atoms, Y1 and Y2 are preferably hydrogen, X is the acid radical of phosphoric acid and the sum of n+m is 2 to 30, preferably 4 to 20. The formulations can additionally contain various assistants such as non-ionic or anionic surfactants and/or organic solvents or polar compounds. The formulations are used for whitening natural and synthetic fabrics, e.g. made from polyamide, cellulose and blended fabrics, as well as paper.
