<p>Provided is an 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 anionicdetersive surfactant.</p> |
