It has many benefits, such as moisturizing the skin, lubricating the skin, protecting and softening the skin, as well as increasing the residence time of the water in the skin, which also affects the skin feel properties of the cosmetic formulation.

 

Regarding the chemical structure requirements of the molecules in the emollient composition, usually the presence or absence of polarity, unsaturation, presence or absence of branches in the molecular chain and its branch position and molecular size can affect the mutual emollients on the surface of the skin. The mechanism of action, which in turn affects its sensory properties to the skin.
