Description

The present invention relates to a skin cleansing composition that is hypoallergenic to the skin and has excellent foam quality.

Conventionally, cleaning agents using amino acid-based surfactants have excellent low irritation to the skin and are comfortable to use, and provide a moist texture, but the foam quality is significantly inferior to cleaning agents using higher fatty acid salts. Various improvements have been made to foam quality (Patent Documents 1 and 2).
