Solstice Propellant is currently being used in some novelty aerosols, OTC sprays, sunscreens, insect sprays, dusters and freeze sprays, and at least one insect spray. It is being evaluated in contact cleaners, mold releases, personal care products, household products and spray paints.
Solstice Propellant can be used in most products that currently use 134a. The major difference between the two is that Solstice Propellant has a lower vapor pressure than 134a. This might make it necessary to reformulate some aerosol products.
Solstice Propellant mixes with 134a, 152a, DME and the hydrocarbon propellants. It also mixes with commonly used solvents like alcohols, ketones and hydrocarbon solvents.
We have found Solstice Propellant to be compatible with tinplate steel aerosol cans, aluminum cans and many aerosol valves. However, it is always advisable to confirm the compatibility of a new propellant with your specific packaging components prior to filling cans for commercial distribution.
No. The reactions that cause Solstice Propellant to breakdown in the atmosphere do not occur under normal storage and use conditions. Solstice Propellant has been shown to have a high degree of thermal and hydrolytic stability. We have demonstrated long-term storage stability in storage containers, cylinders and aerosol cans.
Solstice Propellant has been added to the U.S. EPA TSCA inventory. It has also been added to EPA’s SNAP list of acceptable substitutes for ozone-depleting substances in aerosols and other applications. Solstice Propellant is registered in Europe under REACH, in Japan, China, Canada, Australia and South Korea. Registrations are in progress in New Zealand.
The American Industrial Hygiene Association has set a Workplace Environmental Exposure Level (WEEL) of 800 PPM for Solstice Propellant.
Solstice Propellant is commercially available. It is being supplied from Honeywell’s Baton Rouge, LA facility.
In the U.S., classification of chemicals as VOCs or non-VOCs is based on photochemical reactivity. Solstice Propellant has a very low photochemical reactivity and is classified as a non-VOC by the U.S. EPA. In other regions different definitions are used and Solstice Propellant may be classified as a VOC. In the EU, for example, the determination is based on structure and vapor pressure with no consideration of reactivity.
Solstice Propellant is a UN class 2.2 nonflammable liquefied gas.
Solstice Propellant is miscible with all of the other liquefied gas propellants (HFCs, hydrocarbons and DME). It is also miscible with commonly-used solvents like the lower alcohols, ketones, hydrocarbons and chlorinated solvents.
Yes. Pure Solstice Propellant and Solstice Propellant-based aerosols can be imported into Switzerland.
