The Plan
Bag-on-Valve aluminium aerosol
Laminated bag welded to the valve inside an alu can; compressed air squeezes the bag — propellant never touches the formula.
Pros99% evacuation · continuous 360° spray · protects formula → suits reduced-preservative formulas (sensitive-skin gold) · non-flammable
Consviscosity ceiling ~5,000 cP (confirm vs valve spec) · specialist filling · 15–25% dearer than standard aerosol
~$2.50–5.00/unit filled (est.) · MOQ 5,000 (Aeropac ✅)
WhoAeropac (fill, NSW) · Jamestrong (AU cans) · Aptar valves via Ultrapak AU
MVP fallback
Fine-mist pump + aluminium bottle
Pre-compression pump, fine mist per stroke. Same no-touch experience, no aerosol rules.
Proscheapest · no specialist filling — New Directions AU fills from 100 units · keeps the metal look · easy DTC shipping
Consnot continuous · thin formulas only (HV inserts exist for serums)
US$1.82 bottle+sprayer listed ✅ (SKS 80ml) · MOQ from 1 case
WhoUltrapak (Aptar pumps) · SKS/Cary · New Directions (fill)
Alternative
Continuous-mist pump (Flairosol-type)
Spring-piston chamber gives seconds of propellant-free mist per priming stroke.
Prosaerosol-like mist, zero propellant, no DG shipping, low MOQ stock
ConsPET plastic bottle — clashes with the aluminium/tool aesthetic unless sleeved
~US$2–4/unit small qty (est.)
Alternative
Airless pump bottle
Piston/pouch, no dip tube — vacuum draws product; near-total evacuation.
Prosbest preservation short of BOV · handles serum-to-cream viscosity
Consdosed, not continuous spray
US$1.62 listed ✅ (SKS 50ml) · China ~$0.20–0.70 @5k (est.)
Ruled out
Standard aerosol (LPG propellant)
Whypropellant mixes into the formula, flammable, cold-blast feel, 90–95% evacuation — wrong fit for sensitive skin
