What the product description says
“KOYA Double Cleanse 2-In-1 Facial Cleanser”
From product name

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (capric acid, cocamidopropyl betaine, glyceryl stearate, hydrogenated lecithin, lauric acid, myristic acid, palmitic acid, peg-100 stearate, 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: cocamidopropyl betaine

Palmitic acidEffect: HighAn emollient that is naturally present in skin and helps soften it~3.8–4.6%

Glyceryl stearateEffect: HighAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~0.95–1.2%
Capric acidEffect: High~0.5–0.75%
Hydrogenated lecithinEffect: HighHelps to retain moisture by creating a protective barrier on the skin. Rich in fatty acids. Improves product texture and helps with the penetration of other ingredients.~0.25–0.5%
