活性剤に由来する刺激的な違和感が生じる問題がある。2. Description of the Related Art Various types of surfactants are incorporated in cosmetics according to the purpose. Among them, amphoteric surfactants are incorporated into various cosmetics as emulsifiers, solubilizers, cleaning aids and the like. However, when an amphoteric surfactant is added to cosmetics, it often causes a large stickiness, which is a problem particularly in skin cosmetics. In addition, when an anionic surfactant is contained, there is a problem that an irritating discomfort caused by the anionic surfactant occurs.
