Technical information GPS Safety Summary Propane Substance name Propane CAS-No. 74-98-6 General Statement Propane is a colorless, combustible gas with a very faint odor. It is easily condensable under pressure. The substance is soluble in hydrocarbons, alcohols and ethers, but virtually insoluble in water (<0,1 g/l at 20 °C). Propane is classified as extremely flammable. It is stored and transported as a liquified gas. As a saturated alkane it is chemically relatively stable. As a very pure substance it is for example a valuable aerosol propellant for various products. Chemical identity Name Propane Brand names Propane, DRIVOSOL 78 Chemical name (IUPAC) Propane CAS number 75-28-5 Molecular formula C3H8 Structure H3CCH2CH3 Chemical characterization Short chain saturated hydrocarbon Evonik Industries Industries AG | GPS Safety Summary | November 2011 | Version 1 | page 1/6 Uses and application Propane is used mainly used as an aerosol propellant for various products including cosmetics. It is used as a foaming agent in polymer production. Propane can also be used as energy fuel (Liquified petroleum gas, LPG). The substance is often used in mixture with the very similar substances Isobutane and n-Butane which have very similar properties. Physical/chemical properies Propane is an extremely flammable gas. The boiling point indicates that the substance has a high volatility. Water solubility is low. In case of a release the majority will distribute in air. Property Value Physical state Liquified gas Color Colorless Odor Very faint Density 0.528 g/cm3 (liquified gas) Melting / boiling point -189.9°C / -42.1 °C Flammability extremely flammable gas Explosive Properties Not to be expected in view of the structure, however may form explosive mixtures with air: explosion limits 1.8% (V) - 11.2 % (V) Self-ignition temperature 450 °C Vapor pressure ca. 7800 hPa (20°C) Molecular weight 44,10 g/mol Water solubility <0,1 g/l Flash point Ca. -80°C Octanol-water partition 2.28 coefficient Health effects Effect Assessment Result Acute toxicity (oral, dermal Low acute toxicity, but due to oxygen loss and inhalation) narcotic effects at very high concentrations possible Eye / Skin irritation No data available because product is a gas. Contact with liquid causes frost-bite. Sensitization Not considered to be sensitizing Evonik Industries Industries AG | GPS Safety Summary | November 2011 | Version 1 | page 2/6 Toxicity after repeated Low level long-term toxicity exposure Genotoxicity/mutagenicity Not mutagenic in a battery of in-vitro test systems. In vitro and animal experiments revealed no evidence of potential for hereditary genetic changes. Carcinogenicity According to the results for repeated dose toxicity and mutagenicity tests, carcinogenic effects are not to be expected Toxicity for reproduction No adverse effects on fertility and not selectively toxic to the fetus Environmental Environmental effects Effect Assessment Result Aquatic toxicity The substance is a highly volatile gas. Therefore relevant concentrations in aquatic environment which may cause harmful effects are not to be expected Fate and Behavior Result Biodegradation Substance is a volatile gas. Therefore tests are technically not possible. Structure activity calculations demonstrate readily biodegradability. Bioaccumulation potential Because of the low partition coefficient n-Octanol-water not to be expected. PBT / vPvB conclusion Neither considered to be PBT nor vPvB Propane is not expected to persist in the environment because it is predicted to degrade rapidly in water and air, has a low potential for adsorption to organic matter and has a low potential for bioaccumulation. Exposure Human health Propane is a highly flammable gas and bigger amounts must therefore be handled in closed systems with low level of exposure. Production and use take place in chemical industry with an according safety standard. Evonik Industries Industries AG | GPS Safety Summary | November 2011 | Version 1 | page 3/6 For consumer use where no personal protective measures are presumed to be in use for limitation of exposure it is essential to observe the instructions on product packaging. Environment Because the substance is a highly volatile gas no relevant concentrations in the aquatic environment are to be expected. Released substance will distribute in air where it is photochemically degradable. Risk management recommendations Industry use, production and formulation • The usual protection measures when highly flammable gases are handled have to be observed. • Wear personal protective equipment • Avoid contact with skin and eyes. • Do not inhale vapors / aerosols. • Provide good ventilation or extraction. • Ensure good room ventilation at floor level too. • Vapors are heavier than air and may spread along floors. • Take precautionary measures against static charges, keep away from sources of ignition. • Explosion protection equipment required. • Keep away from flames and hot surfaces. • Avoid heat effect and sources of ignition. • No smoking. • Do not empty into drains. • If positive displacement pumps are used, these must be fitted with non-integral pressure relief valve. • Priority should be given to closed-system units. • Observe special instructions applicable to compressed gases. • Keep containers tightly closed in a cool, well-ventilated place with exclusion of air/oxygen Consumer use To limit exposure for consumer use it is essential to observe the instructions on product packaging.
