What Is C20-24 Olefin?
C20-24 Olefin is a synthetic hydrocarbon derived from petroleum. It belongs to a class of ingredients known as olefins—unsaturated hydrocarbons with a double bond in their chemical structure. In skincare formulations, it functions primarily as a skin conditioning agent.
This ingredient is used in very small amounts across skincare products, appearing in approximately 0.1% of formulations. Its role is to help improve the texture and feel of a product on the skin, contributing to a smoother application and finish.
How It Works
C20-24 Olefin works by forming a light occlusive layer on the skin's surface. This helps to smooth fine texture and creates a more uniform appearance without leaving a heavy or oily residue. The ingredient's conditioning properties allow it to improve the overall sensory experience of a skincare product.
Clinical Evidence & References
Published clinical research specifically examining C20-24 Olefin in skincare is limited. The ingredient's use is supported primarily by industry experience and cosmetic science principles rather than extensive peer-reviewed studies. It is generally recognised as a safe and effective conditioning agent in the concentrations used in cosmetic formulations.
How to Use
C20-24 Olefin is typically incorporated into formulations at very low concentrations (well below 1%), so no special application technique is needed. Use products containing this ingredient as directed on the label, and combine with other appropriate actives or moisturisers based on your individual skin needs.
