What the product description says
“2-in-1 Hair & Body Wash”
Source: 31st State

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (ammonium lauryl sulfate, cocamidopropyl betaine, decyl glucoside, sodium lauroyl sarcosinate) 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: ammonium lauryl sulfate, cocamidopropyl betaine, decyl glucoside

Ammonium lauryl sulfateEffect: High~9.5–14.2%
Cocamidopropyl betaineEffect: HighHelps water and oil mix together. Used as a cleansing ingredient. Could be an allergen~5–7.5%
Sodium lauroyl sarcosinateEffect: HighHelps oil and water mix together and works as a cleansing agent~1.8–2.7%
Decyl glucosideEffect: HighHelps oil and water mix together. Can be irritating~1.6–2.4%
