Phytosteryl/ Octyldodecyl lauroyl glutamate is used as an emollient and skin conditioning agent in cosmetic products. As mentioned earlier it fills up the gaps in between the skin cells in the epidermis and forms a firmer structure. It forms a thin film on the surface of the skin. It forms a barrier and protects the skin from allergens, bacteria, and irritants which pass into deeper layers of the skin. Otherwise which may lead to conditions like acne, eczema, dryness, and itchiness on the skin. Dry skin is more susceptible to various irritating skin conditions as mentioned before.
