What it is
Toners, essences and face mists share one water-based system in different packs: a thin solution of humectants, soothing ingredients and sometimes mild acids. Toners are swept on with a pad, essences are patted in from a bottle, and mists are sprayed from a fine-mist pump. All three layer easily and suit refreshing top-ups during the day.

Lab notes
Preservation
Required, as water activity is high and hydrosols need low starting microbial counts. Challenge test to ISO 11930.
Stability testing
Storage at 40–45 °C and 4 °C, light exposure for clear packs, clarity and cloud point, and spray pattern and pump function over time.
Regulatory, Australia
Cosmetic; anti-acne toners stay cosmetic only when presented as controlling or preventing acne solely through cleansing, moisturising, exfoliating or drying the skin, and contain no substance in Schedules 2, 3, 4 or 8 of the Poisons Standard. Aerosol mists are dangerous goods for transport and storage.
