It’s able to trap moisture into the skin by forming ah occlusive layer. This is very beneficial for dry-very dry skins as it will reduce irritation and help sooth the skin while reducing flakiness.
Propanediol can also function as a humectant meaning it can attract moisture to the skin from the environment.
