Description:
Part I of this report discusses the U.S. aerosol industry's experience in converting from chlorofluorocarbon (CFC) propellants to alternative aerosol formulations. Detailed examples of non-CFC formulations are provided for 28 categories of aerosol products. ydrocarbon propellants, which cost less than CFCs, are most often selected as the propellants of choice unless special properties such as increased solvency or reduced flammability are needed. imethyl ether is the next most preferred CFC alternative, although it is flammable and a strong solvent. arbon dioxide, nitrous oxide, and nitrogen are inexpensive and widely available, but have been underused as aerosol prepellants. pecial equipment is often needed to add them to the aerosol containers. A variety of alternative aerosol packaging forms are discussed in Part II, with special focus on those most like regular aerosols in characteristics. Advantages and drawbacks of several types of alternative dispensing devices are discussed in detail and examples are provided of the types of consumer products which have successfully utilized these alternatives.
