In reality CFCs haven't been used as aerosol propellants since 1978. In focus groups consumers indicated they often look to product labels for information. In response the aerosol industry is moving to place a universal "No CFCs" logo or statement on every aerosol can. Thus far about one-third of the aerosol industry has agreed to modify their labeling. Such well-known aerosol products as those marketed by SC Johnson Wax Racine WI already bear the logo and CAPCO is hopeful other manufacturers will follow suit. Developing the universal logo meant winning the Environmental Protection Agency's (EPA) approval since the agency does not allow listing an ingredient not contained in a registered package on the label. The logo also had to meet the standards of the Federal Trade Commission's environmental labeling guidelines.
