Lipstick is composed of wax, oil, moisturizer and pigment. The exact recipe varies from manufacturer to manufacturer. However, a mixture of several different types of waxes is normally used, including beeswax, carnauba wax and paraffin. The ratio of the ingredients is carefully formulated so that the lipstick has a high enough melting point so it won't melt on hot days.
First, the various ingredients are measured and added to a mixer. Heat is applied and the ingredients are mixed until a uniform consistency is achieved. The molten mixture is then transferred into molds in the shape of the individual sticks. The molds are cooled until the mixture solidifies. The sticks are then removed from the molds and placed inside plastic lipstick containers.
