Polymer use began in the 1800s with cellulose derivatives, the vulcanization of rubber, and styrene synthesis; but in reality, it started more than four million years ago with the formation of DNA and proteins. Polymers are a diverse class of chemistry. By definition, they are large molecules made up of chains or rings of linked monomer units—simple reactive building blocks. Smaller molecules or monomers are combined to form polymers that possess a characteristic chain structure of multiple repeating units that can be related or different.

The authors describe how the use of amphiphilic silicones or surfactant silicones has allowed formulators to efficiently incorporate silicone polymers into personal care products. These materials act by lowering the surface tension in the oil phase of a formulation, allowing for easier spreading on skin and hair.
