Method for prevention or treatment of periodontal diseases and composition for an oral cavity

A detergent composition comprising (a) 0.1 to 95% by weight of a saccharide nonionic surfactant and (b) 0.01 to 5% by weight of an antibacterial agent. The detergent compositions are outstandingly mild to the skin, exhibiting a high antibacterial effect, without influencing or weakening the cutaneous metabolic and barrier functions of the skin. The detergent compositions can effectively restrain the early occurrence of dandruff after shampooing when used as detergents for the scalp and the hair. They also exhibit high antibacterial effect when used as body detergents.
