What the product description says
“by Petra Hydrating Milky Cleanser”
Source: Lookfantastic

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (cocamidopropyl betaine, glyceryl stearate, glycol distearate, myristic acid, palmitic acid, peg-100 stearate, sorbitan olivate, 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

Myristic acidEffect: HighHelps oil and water mix together. Could be comedogenic~7.3–8.9%
Palmitic acidEffect: HighAn emollient that is naturally present in skin and helps soften it~2.4–2.9%
Glyceryl stearateEffect: HighAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~2–2.4%
Glycol distearateEffect: HighHelps water and oil mix together~1.7–2%
Stearic acidEffect: HighHelps oil and water mix together and works as an emollient~1.5–1.9%
Cocamidopropyl betaineEffect: HighHelps water and oil mix together. Used as a cleansing ingredient. Could be an allergen~1.3–1.5%
Sorbitan olivateEffect: HighHelps oil and water mix together~1.2–1.4%
Peg-100 stearateEffect: HighHelps oil and water mix togehter and creates a nice product texture~0.8–1.2%
LecithinEffect: High, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.3–0.5%
