NONFLAMMABLE PROPELLANT

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.

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
