What the product description says
“Rinka Cleansing Gel”
Source: Yesstyle

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (cocamide dea, coco-betaine) 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

Coco-betaineEffect: HighHelps oil and water mix together and works as a cleansing agent. Can be allergenic~5.3–7.9%
Cocamide deaEffect: High~2.4–3.6%
