Formulation notes

Functions in pressurised aerosol cans. No skin-active function — propellant role only. Flammable — fire-safety labelling required on packaging.

Watchouts

Highly flammable — appropriate storage and use warnings required. LPG-derived; fossil fuel origin may be flagged by ultra-sustainable brands exploring compressed air alternatives.

Clean beauty perception

Generally accepted in clean beauty. Not present on clean ingredient ban lists. Fossil fuel origin occasionally noted but no established health concern at cosmetic use.
