Abstract
To develop lipstick products with superior moisturizing effect using moisture base, bound water capacity and water holding capacity were investigated by DSC. Bound water capacity of the lipstick sample excluding moisture base is found to be 5.12 %. DSC measurement showed that bound water capacity and the concentration of moisture base were positively correlated. Additionally, DSC measurements and in vitro effective water holding capacity measurement showed similar patterns. Therefore, measuring of bound water capacity by DSC can predict the moisturizing effect of lipstick products.
