Solstice® Propellant: Product Innovation Propelled

Solstice Propellant is an exciting advancement for aerosol-based personal care products, which are becoming increasingly popular among consumers.

As these products become even more competitive, there is a growing trend toward propellants that enable packaging design that can set your products apart from the crowd.

Solstice Propellant 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. It is classified as a UN class 2.2 nonflammable liquefied gas, and has a WEEL of 800 ppm.

  • Environmentally-Preferred
  • Easy Conversion
  • Quick Drying
  • Packaging Flexibility
  • Consistent Spray

STAY AHEAD OF CHANGING REQUIREMENTS: With the Kigali Amendment to the Montreal Protocol, many countries are eventually phasing out hydrofluorocarbons (HFCs) due to high global-warming potentials (GWPs). Solstice Propellant offers an ultra-low GWP alternative to HFC-152a and other HFCs.

MEETS VOC TARGETS: Solstice Propellant is VOC-exempt (U.S. EPA).

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: It is the only nonflammable, ultra-low GWP liquefied gas propellant available today. Hydrocarbons may require special flammable materials handling equipment.

FAST EVAPORATION: Spray small-sized droplets for quick dry time.

Solstice Propellant is the only liquefied propellant that enables packaging in plastic aerosol bottles:

  • Nonflammable liquefied gas propellant allows formulation of nonflammable products which can be transported under current regulations
  • Suitable vapor pressure range for developing formulations compliant 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 through PET is 1/29th that of carbon dioxide

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.
