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, anti-perspirants, 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.
本发明涉及一种稳定的初始冲击和连续冲击香气和/或效益剂-传递微囊化香气和/或效益剂的水悬浮液,例如,恶臭对抗剂悬浮在非限制香气含量和/或效益剂含量的液相油包水乳化液中。在储存过程中,悬浮液的粘度在长时间内仅略微增加,从而避免了在将悬浮液与其他材料混合时产生不良的搅拌阻力。因此,该悬浮液可用于向可消费材料(例如液体阴离子、阳离子、非离子或双性洗涤剂、洗发水、沐浴露、液体肥皂、护发素、皮肤乳液、止汗剂、除臭剂或液体柔顺剂和/或调理剂组成)传递效益或香气。还描述了一种制备这种稳定悬浮液的方法和用于执行这种方法的设备。
