December 2014 Spray 21 Joe Wolfgang, Malvern Instruments, spoke on particle size analysis and the company’s instruments used to measure it. Particle size is of particular importance to the aerosol industry, due to concerns among consumers about inhalation of small particles, especially with sun care products. Particle size matters not just for preventing health hazards such as inhalation or optical contamination, Wolfgang argued, but also for product performance, such as drying time for spray paints or pharmaceutical products designed to be inhaled. It was noted that spray particle quantity—as well as volume— should always be considered. Hazi Mistry and Amy Lawrence of Safeware Quasar delivered the day’s final presentation. Perhaps appropriately, International Aerosol Shipping served as the global complement to the day’s first presentation on domestic shipping requirements. The presentation primarily focused on changes resulting from standardization efforts in accordance with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), and the differences between U.S. and EU requirements. Lawrence described the GHS labeling system and its use of precautionary statements, along with pictograms and signal words. Any product which may cause physical, health or environmental hazards must be labeled, they said. Hazcom 2012, in alignment with GHS, goes into effect June 1, 2015.
