How are Lipsticks Made?

There are three major steps required in manufacturing lipsticks such as melting and mixing, pouring the mixture to the tube and then packaging the product for sale. Because the lipsticks can be mixed and stored, the mixing does not take place at the same time as pouring. If the lipstick is already placed into the tube, the packing for retail sale is done first and it highly varies, depending the how the product is going to be marketed.

Melting and mixing:

  • The raw materials for the lipstick are first to be melted and then mixed. This is separately done due to the various types of ingredients used. On mixture is containing the solvent, and the second contains oils and then the third one contains the waxy materials and fats. All of these are heated separately in stainless steel or any ceramic container.
  • The solvent solution and liquid oils are combined with the color pigments. After the pigmenting mass is mixed, the hot wax mass is added until consistency and uniform color is achieved. In case the fluid lipstick is to be immediately used, the melt is maintained at temperature with pressure in order for the trapped air to escape.

Molding:

  • After the lipstick mass is mixed and totally air-free, the next step is to pour it inside the tube. Variety of machine setups is used, depending on the manufacturer’s machine. The melted mass is distributed into a mold, consisting the bottom portion of the plastic or metal tube and the shaping portion that closely fits with the tube. The lipstick is poured upside down in order for the bottom of the tube to be at the top of the mold.
  • Then the lipstick is cooled and separated from the mold. It passes through a flaming cabinet for pinhole sealing and to improve finish.

Labeling and packaging:

  • After retracting the lipstick and capping the tube, the lipstick will now be ready for labeling and packaging. The labeling is done to identify the batch and then the packaging, which is the final step, is done by choosing among the different packaging options available.
