Product Innovation Propelled
With the Kigali Amendment to the Montreal Protocol, many countries are phasing out hydrofluorocarbons (HFCs) due to high global-warming potentials (GWPs). It’s time for a fresh perspective about how we can help preserve our planet without compromising on product performance.
Look to Solstice® Propellant (HFO-1234ze(E)), a groundbreaking, Earth-friendly aerosol propellant to help create creamy, shiny, and easy to spread foams in aerosol-based products for face, body, hair, and sun care products. And using our nonflammable propellant in cosmetic and cosmeceutical formulations creates the ability to spray small-sized droplets for quick dry time.
Solstice Propellant offers an ultra-low GWP alternative to HFC-152a and other HFCs. Our nonflammable propellant meets VOC targets, and is a proven alternative to flammable propellants or high GWP HFCs. Solstice Propellant is VOC-exempt (U.S. EPA), and is classified as a UN class 2.2 nonflammable liquefied gas.
Our nonflammable solution can be blended with other common propellants such as HFC-152a, DME, butane, isobutane and propane, and commonly used solvents including alcohols, acetone, halogenated and hydrocarbon solvents. It is thermally and hydrolytically stable and exhibits good compatibility with plastics, elastomers, and metals.
Solstice® Aire can be used to replace your existing propellant in meter dose inhalers. A GMP grade is available for testing.

MAXIMIZES PACKAGING DESIGN FLEXIBILITY
Solstice Propellant is the only liquefied propellant that enables packaging in plastic aerosol bottles:
- Nonflammable liquefied gas propellant allows formulation of nonflammableproducts which can be transportedunder current regulations
- Suitable vapor pressure rangefor developing formulationscompliant with U.S. DOT plastic aerosol pressure restrictions
- Compatible with PET plastic aerosol bottles: No degradation after >12 months at 104°F (40°C)
- Very low loss rate: Diffusion rate throughPET is 1/29th that of carbon dioxide
EFFICIENT AND EASY CONVERSION
Minimal conversion costs: Honeywell’s experienced team helps ensure a smooth, efficient transition
Compatible with existing equipment: Few changes to existing storage and filling equipment are required
Focus on safety: The only nonflammable, ultra-low GWP liquefied gas propellant available today; hydrocarbons may require special flammable materials handling equipment
CONSISTENT, EFFECTIVE SPRAY PERFORMANCE
Medium pressure (49 PSIG at 70°F /21°C): Provides even, consistent spray with minimal overspray. Ideal for hair and facial applications
Higher liquid density (1.17 g/cc at 70°F/21°C): Enables better solubility in viscous formulations; works very well in formulations containing inorganics, such as zinc oxide
