Abstract: Mild aqueous detergent, e.g., shampoo, compositions are disclosed based on a mixture comprising anionic surfactant and amphoteric surfactant, such as betaines, present in the composition at a level of from about 0.75 to 1.25 parts by weight per part by weight of anionic surfactant. The compositions also contain one or a mixture of therapeutic agents such as climbazole or a mixture of climbazole and one or more co-therapeutics such as salicylic acid. The combination of mild surfactant system and therapeutic agent serve to prevent or treat mild skin disorders such as scalp itch and scalp irritation when applied to the scalp as a shampoo. Shampoo compositions also preferably contain one or more conditioning agents and suitable suspending agents.
