ISOBUTANE.

Valuable CAS 75-28-5 / PROPELLANT

Isobutane is a highly volatile hydrocarbon utilized primarily as an aerosol propellant, enabling efficient product delivery from spray formulations. It also functions as a foaming agent and a solvent, evaporating rapidly upon application to minimize skin contact.

Summary

propellant solvent foaming agent

Science

Mechanism of Action

Isobutane works as a pressurized gas within aerosol systems, creating the force needed to expel formulations from containers. Its rapid evaporation upon release facilitates the quick dispersion of products and leads to minimal residual presence on the skin, reducing potential for interaction.
