Abstract
Abstract An aqueous aerosol composition is composed of a homogenized dispersion of lecithin in water and contains a propellant, e.g., carbon dioxide or nitrous oxide, for pressurizing the composition in an amount sufficient to produce a release coating of lecithin on a surface when the composition is sprayed. Other ingredients such as preservatives, i.e., bacteriostats and/or fungistats, and supplemental emulsifiers can be included where desired or needed.
