I have been wandering around the aerosol industry for the last 35+ years both as an employee of major CPG companies, and, for the past 15 years as an independent aerosol technical consultant. While the attention to safety issues has dramatically improved over time, I am still amazed how often the simplest safety precautions are sometimes overlooked when filling aerosols with flammable propellants. I'll save my horror stories for another time, except for one particularly relevant example at the end of this article.
This series, "Aerosol Anatomy," will dissect and examine various technical topics in aerosol technology, including product development, new technology, components of the aerosol system, and quality control.
This article continues the Aerosol Anatomy series, which dissects and examines various technical topics in aerosol technology, including product development, new technology, components of the aerosol system, and quality control of aerosol products.
This is a continuation of the Aerosol Anatomy series, which focuses on dissecting and examining various technical topics in aerosol technology, including product development, new technology, components of the aerosol system, quality control and other related topics of interest to formulators and manufacturers of aerosol products.
Dr. Charles R. Anderson has long specialized in the Characterization of Surfaces, Interfaces, Thin Films and Coatings. Since 1972 he has applied surface and near-surface analysis techniques such as x-ray photoelectron spectroscopy (XPS or ESCA) and Auger microprobe to the solution of surface chemistry and coating problems. He worked for the U.S. Navy and Lockheed Martin Laboratories prior to starting his own laboratory in 1995. Dr. Anderson served as an officer of the ASTM Committee E-42 on Surface Analysis and as U.S. Expert on several sub-committees of the ISO Technical Committee 201 on Surface Chemical Analysis. He especially enjoys integrating the results of multiple analytic techniques (surface analysis, thermal analysis, FTIR, SEM/EDX, optical microscopy)to solve tough materials problems. Dr. Anderson has extensive experience in materials science as a result of solving the materials problems of many industries with the aid many analytical techniques. He is available to provide Expert Witness Services for legal matters involving Materials Failure, Intellectual Property Theft, Misrepresentation, Failure to Meet Contract Specifications, Materials Identifications and Characteristics, or Quality Issues. To ensure the accuracy and integrity of his testimony, Dr. Anderson and his staff independently analyze the relevant materials in most cases. View Consulting Profile.
