    • A process for the incorporation of microcapsules with anionic charge into a structured aqueous concentrated liquid detergent comprising at least 30 wt%, preferably at most 65 wt%, total surfactant of which at least 5 wt% based on the total composition is anionic surfactant, including soap, and an external structurant, the process comprising the combining of two premixes; Premix A which is the structured aqueous concentrated liquid detergent composition without microcapsules and Premix B which comprises an aqueous dispersion of the microcapsules with anionic charge, characterised in that: Premix B is a slurry of microcapsules with a maximum viscosity at 25°C of 100 mPas and at least 90 wt% of the microcapsules having a particle size in the range 5 to 30 microns, and that Premix B is added to Premix A and the resulting combined mixture is passed through a static in-line mixer with an energy input of from 20 to 500 J/kg to form, immediately after the mixer, a structured liquid comprising less than 10%, based on the total number of groups of microcapsules, agglomerated groups of microcapsules, an agglomerated group of microcapsules being defined as a group having more than 5 microcapsules grouped together.
    • 含有阴离子电荷的微胶囊结合含水浓缩液体洗涤剂的方法包括至少30重量%,优选至多65重量%的总表面活性剂,其占总组合物至少5重量%是阴离子表面活性剂,包括 肥皂和外部结构剂,该方法包括组合两种预混物; 预混合物A,其是没有微胶囊的结构化水性浓缩液体洗涤剂组合物和预混物B,其包含具有阴离子电荷的微胶囊的水性分散体,其特征在于:预混合物B是在25℃下最大粘度为100mPas的微胶囊 并且至少90重量%的微胶囊具有5至30微米的粒度,并且将预混物B加入到预混物A中,并将所得的组合混合物通过静态在线混合器,其能量输入为 20至500J / kg以在混合器之后立即形成包含小于10%的结构化液体,基于微胶囊组的总数,微胶囊的团聚组,凝聚的微胶囊组被定义为具有更多 超过5个微胶囊组合在一起。
