Abstract (en)

[origin: WO9414939A1] A cleaning composition contains (a) a detersive surfactant and (b) a poly(amino acid) compound or a precursor thereof, the said component (b) being protected from contact with a level of alkalinity as would cause degradation thereof. The component (b) may be stabilised by, for example, coating it with an organic acid compound or with a film-forming polymer; by agglomerating it with a controlled level of alkaline or alkaline-reacting compound (e.g. sodium carbonate); by spray-granulating it in admixture with a nonionic surfactant; by encapsulating it with a silicone-based resin; or by incorporating it in a composition that is non-alkaline. The storage stability of the compositions is thereby improved.
