| In California, aerosol products must be manufactured in compliance with the state's Clean Air and Water Act. Current legislation requires that there be no more than 80% volatile organic compounds (VOCs) in these products. Before the year 2000, this limit will be reduced to 55%, thus requiring manufacturers to reformulate their products.; This study addressed these regulations as they apply to hair spray. The objective was to develop new formulas, and identify packaging components to facilitate compliance with these regulations, while maintaining the same features and quality that consumers demand.; The program was primarily concerned with the formulation, and testing of hair sprays that meet the new standards. The investigation compared the proposed 55% formulations to current 80% formulations as well as to previous non-regulated formulations. The criteria examined include the physical, subjective, chemical, safety, stability and cost factors. Reliability outcomes based on these data are also presented. |
