What the product description says
“5.5 Cleansing Foam EX”
Source: Yesstyle

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (coco-betaine, palmitic acid, potassium cocoate, potassium cocoyl glycinate, sodium cocoyl isethionate, stearic acid) and should be able to cleanse the skin gently. Still keep in mind that any cleansing can disrupt the skin barrier, and most people do not need to cleanse their skin more than once per day.

Even though this formulation is mild, the following cleansing agents could trigger an irritation or allergy for some people: coco-betaine

Sodium cocoyl isethionateEffect: HighHelps water and oil mix together. Can be used as a cleansing agent~9.8–12%
Potassium cocoyl glycinateEffect: High~2.3–2.9%
Coco-betaineEffect: HighHelps oil and water mix together and works as a cleansing agent. Can be allergenic~2–2.4%
Stearic acidEffect: HighHelps oil and water mix together and works as an emollient~2–2.5%
Potassium cocoateEffect: HighHelps oil and water mix together and works as a cleansing agent~1.4–1.7%
Palmitic acidEffect: HighAn emollient that is naturally present in skin and helps soften it~0.45–0.7%
