    • 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 stabilized 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.
    • 清洁组合物包含(a)去污表面活性剂和(b)聚(氨基酸)化合物或其前体,所述组分(b)被保护不会与碱度水平接触,从而导致其降解。 组分(b)可以通过例如用有机酸化合物或成膜聚合物涂覆来稳定化; 通过使其与受控量的碱性或碱性反应化合物(例如碳酸钠)结合; 通过与非离子表面活性剂的混合物喷雾成粒; 通过用硅氧烷基树脂包封它; 或通过将其并入非碱性的组合物中。 从而提高了组合物的储存稳定性。

    • Disclosed is a process for making a detergent composition comprising the steps of:i) making a detergent based composition comprising a solid acid source;ii) coating the solid acid source with a detergent surfactant; andiii) further adding an alkaline source and agglomerating said alkaline source with said acid source;and wherein the alkaline source and the acid source are capable of reacting together to produce a gas. Detergent compositions thus prepared show improved dispersability. Methods of laundering fabrics using such detergent compositions are disclosed.
