Is HFC-152a a VOC?
Is HFC-152a a VOC?
Figure 1 below shows a simplified hypothetical aerosol deodorant body spray product formulation using a propellant system of ethanol, liquified petroleum gas (LPG) and HFC-152A and has 75% VOC content by weight.
Is 152a flammable?
Although stable, HFC-152a is a flammable gas with a lower flammability limit of 3.9% (Table 1); contact with open flames and high temperatures must thus be avoided. HFC-152a will form HF and possibly carbonyl fluoride (COF2) on decomposition.
Is Difluoroethane a fluorocarbon?
This colorless gas is used as a refrigerant, where it is often listed as R-152a (refrigerant-152a) or HFC-152a (hydrofluorocarbon-152a). It is also used as a propellant for aerosol sprays and in gas duster products….1,1-Difluoroethane.

Is HFC-152a toxic?
Hydrofluorocarbon 152a has a low order of toxicity on both an acute and chronic basis. Although a TLV® has not been established for HFC-152a, a value of 1,000 ppm (v/v; 8-hour TWA) seems appropriate based on its low toxicity and analogy to other fluorocarbons.
What is hydrofluorocarbon used for?
Hydrofluorocarbons (HFCs) are greenhouse gases (GHGs) commonly used by federal agencies in a wide variety of applications, including refrigeration, air-conditioning (AC), building insulation, fire extinguishing systems, and aerosols.
What is HFC propellant?
Honeywell HFC-134a Genetron 134a is a non-ozone depleting, non-VOC propellant which is used in a variety of industrial aerosol formulations where nonflammability is desireable or essential. It has a vapor pressure profile similar to that of CFC-12 and is miscible with a variety of propellants and solvents.
Is 152a a hydrocarbon?
As a result, HP 152a and HP 152a/hydrocarbon blends can be used to produce aerosol formulations possessing a lower degree of flammability than their hydrocarbon-propelled counterparts. This may be an advantage in products with high propellant levels, e.g., antiperspirants.
What is Difluoroethane used in?
1,1-Difluoroethane is a colorless and odorless gas which is used as a liquefied compressed gas. It is used as a cooling agent, as an aerosol propellant, and in the manufacture of other chemicals.
Is difluoroethane heavier than air?
Difluoroethane is heavier than air and vapors of the gas can travel a considerable distance to a source of ignition and flashback. When involved in a fire, this material may decompose and produce toxic gases (i.e. carbon dioxide, carbon monoxide, hydrogen fluoride).
What does hydrofluorocarbon 152a do for hair?
Hydrofluorocarbon 152A is used as propellant and foam expansion agen in our Hair Care products such as hairsprays and styling mousses. A propellant is needed to expel the product through the nozzle during application and for a homogenous distribution of the product on hair.
