Abstract (en)
[origin: WO9208781A1] Aqueous surfactant pastes, in particular those containing non-ionic surfactants of the alkylglycoside type, are given excellent storage stability against microbial attack when, following an oxidative bleaching procedure to remove alkali-sensitive pigments, the pH is adjusted to a value of at least 11 by the addition of alkaline substances.
