Fragrances are volatile. They react with other components and are susceptible to heat, moisture and various other factors. Therefore, it is important to control the release of fragrance raw materials over a desired site and at a desired rate.

Controlled-release Mechanisms of Fragrances

Fragrances are volatile and susceptible to oxidation, and can escape from a finished product over time. This limited longevity has led to the development of encapsulation and controlled-release techniques. The present article reviews methods for controlling the release of fragrance in personal care products, and describes their mechanisms of action.

Polymers in Personal Care

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.
