To modulate the hardness of the solid lipstick, this study investigates the factors that might affect the hardness of simple oil-wax systems such as viscosity and polarity of various cosmetic oils with polyethylene wax. The crystallization and structures of the low molecular weight PE wax in such systems were investigated by DSC and SEM. Then the correlation between the hardness of the lipstick and its deposit amount on the bioskin is discussed.
