What the product description says
“Cucumber De-Tox Foaming Cleanser”
Source: Sephora AU

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (cocamidopropyl betaine, coco-glucoside, decyl glucoside, glyceryl oleate, lauryl glucoside, peg-40 hydrogenated castor oil, peg-7 glyceryl cocoate, polysorbate 20, sodium cocoamphoacetate, sodium cocoyl glutamate, sodium lauryl glucose carboxylate, sodium methyl cocoyl taurate, trideceth-9) 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: cocamidopropyl betaine, coco-glucoside, decyl glucoside, glyceryl oleate, sodium methyl cocoyl taurate
