The significance of complex polysaccharides in personal care formulations

Complex polysaccharides have numerous pharmacological activities, such as antioxidant, antibacterial, antiviral, immunomodulating, anticoagulant and anticancer effects. In personal care products, these biopolymers are used as thickener and stabilizing agents or as moisturizing ingredients that could be beneficial to the skin. Various polysaccharides, such as glycosaminoglycans (GAGs), hyaluronic acid (HA), carrageenan, fucose, fucoidan, chitin, chitosan, etc., have applications in cosmeceutical industries. GAGs and HA incorporated in moisturizing creams strengthen the skin barrier by forming a protective layer which prevents transdermal water loss. Therefore, these polysaccharides have been formulated into potential cosmeceuticals and biopharmaceuticals.
