    Abstract: Provided is a anti-dandruff shampoo composition comprising: (a) from about 8% to about 40%, by weight, of anionic detersive surfactant; (b) from about 0.1% to about 5%, by weight, of particulate anti-dandruff agent having an average particle size of from about 0.35 microns to about 5 microns; (c) from about 0.01% to about 1.0%, by weight, of a stabilizing agent for said anti-dandruff agent, said stabilizing agent being a soluble cationic polymer; (d)from about 50% to about 91.89%, by weight, water; wherein said shampoo composition is substantially free of suspending agents selected from the group consisting of crystalline suspending agents and anionic, nonionic, and amphoteric polymeric suspending agents. Also provided is a process used for making the present compositions wherein said particulate anti-dandruff agent and said cationic polymer are admixed in water in the presence of anionic detersive surfactant.

    Abstract translation: 提供了一种抗头皮屑洗发剂组合物，其包含：（a）约8重量％至约40重量％的阴离子去污表面活性剂; （b）约0.1％至约5％重量的平均粒度为约0.35微米至约5微米的颗粒状抗头皮屑剂; （c）约0.01重量％至约1.0重量％的所述抗头皮屑剂的稳定剂，所述稳定剂是可溶性​​阳离子聚合物; （d）约50％至约91.89％（重量）的水; 其中所述洗发剂组合物基本上不含选自结晶悬浮剂和阴离子，非离子和两性聚合物悬浮剂的悬浮剂。 还提供了用于制备本发明组合物的方法，其中所述颗粒状去头皮屑剂和所述阳离子聚合物在阴离子去污表面活性剂存在下混合在水中。
