Figure 2: IR Image of formulation with 6% Solstice Enhance (left) vs 6% Iso-pentane(right) over time
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. Additional benefits include:
Environmentally Preferred
• Stays ahead of changing requirements and
environmental regulations
• Meets VOC targets
Easy Conversion
• Minimal conversion costs
• Compatible with existing equipment
• Focus on safety
Quick Drying
• Fast evaporation properties
Packaging Flexibility
• Solstice liquefied propellant enables packaging in
plastic aerosol bottles
Consistent Spray
• Medium pressure (49 PSIG at 70°F /21°C)
• Higher liquid density (1.17 g/cc at 70°F/21°C)
Inspiring new product ideas
Honeywell’s Solstice Enhance (HFO-1233zd(E)) delivers a refreshing
cooling sensation on contact. An IR image of formulations
with Solstice Enhance vs. Iso-pentane revealed that cooling from
Solstice Enhance lasted much longer than Iso-pentane and was
more uniform. With these additional benefits, formulators can
take formulations to a whole new level:
• Make safer cooling formulations for skin, hair and body.
• Develop new and cooling sensation-based body gels and skin
crackling lotions
• Develop formulations with an instant and prolonged cooling effect
when combined with Solstice Propellant and/or Isopentane
• Achieve a refreshing cooling sensation on contact for the next
breakthrough product idea
Innovative contract manufacturing firms have been working with
Solstice Enhance and Solstice Propellant to develop and commercialize
new concepts in cooling. Scott Carpenter, VP Marketing &
Partner Innovation, Formulated Solutions, noted:
“Formulated Solutions has enjoyed a long and mutually beneficial
working relationship with Honeywell, whose materials have helped
to enable some of the breakthrough custom formulations we’ve been
able to offer to our brand partners in the consumer health care and
prestige personal care categories, including in cryogenic applications.
