Description

TECHNICAL FIELD The present invention relates to a hair cleansing composition containing miconazole nitrate.

Seborrheic dermatitis is one of the causes of dandruff. The main cause of seborrheic dermatitis is thought to be the overgrowth of a fungus called Malachia, one of the resident bacteria of the scalp. When Malachia spp. Grows abnormally, triglycerides in sebum are decomposed more than necessary, and fatty acids are produced more than necessary. Unnecessary fatty acids can irritate the skin, which is the cause of seborrheic dermatitis.

In order to prevent seborrheic dermatitis, a detergent composition containing an azole antifungal agent, particularly miconazole nitrate, as disclosed in Patent Document 1 has been studied from the viewpoint of its effect on Malassezia sp.
