Cosmetics and personal care formulations typically comprise a wide range of ingredients required to fulfill various functional roles. Combining these, often very different, ingredients into a stable formulation without sacrificing their respective functionalities is an ongoing challenge for the cosmetic industry.
Recent advances in the field of reversibledeactivation radical polymerisation (RDRP – more commonly referred to as living radical polymerisation or controlled radical polymerisation)1 have provided novel polymers through unprecedented control over the composition, functionality and architecture of polymers. These methodologies are currently being applied to meet the demands imposed.
This contribution highlights the attributes of the RAFT (reversible additionfragmentation chain transfer) process2 as ground breaking in this context and arguably the most versatile of the RDRP methods.3–9 Polymers made by RAFT polymerisation provide the cosmetic chemist and formulator the right materials for solutions which are both simpler to implement and more effective than conventional alternatives.
