Described is a stable initial impact and continuous impact fragrance and/or benefit agent- imparting aqueous suspension of microencapsulated fragrance and/or benefit agent, e.g., malodour counteractant suspended in a non-confined fragrance-containing and/or benefit agent-containing liquid phase oil-in-water emulsion. On storage, the viscosity of the suspension undergoes a minimal increase over an extended period of time thereby avoiding undesirable agitation resistance during the blending of the suspension with other materials. The suspension is thus useful for imparting a benefit or an aroma to a consumable material such as a liquid anionic, cationic, non-ionic or zwitterionic detergent, a shampoo, a bodywash, liquid soaps, hair conditioners, skin lotions, antiperspirants, deodorants or liquid fabric softener and/or conditioner compositions. Also described is a process for preparing such stable suspensions and apparatus for carrying out such process.
所述的是一种稳定的初始影响和持续影响香味和/或益效剂的水性悬浮液,该悬浮液由微胶囊化的香味和/或益效剂(如恶臭抑制剂)组成,悬浮于非封闭的含香味和/或益效剂的液相水包油型乳液中。在储存过程中,悬浮液的粘度在较长时间内的增加幅度很小,从而避免了在悬浮液与其他材料混合时出现不理想的搅拌阻力。因此,该悬浮液可用于向液体阴离子、阳离子、非离子或齐聚物洗涤剂、洗发水、沐浴露、液体肥皂、护发素、护肤乳液、止汗剂、除臭剂或液体织物柔软剂和/或护理剂组合物等消耗材料中添加益处或香味。此外,还介绍了制备这种稳定悬浮液的工艺和实施这种工艺的设备。
