Melbourn Scientific has introduced a suite of aerosol characterisation services to support the general aerosol industry.
Inhalation of spray particles is one of the health risks that aerosol manufacturers have to address following the update to the Aerosol Dispensers Directive 75/324/EEC, which comes into force in April 2010.
From 29 April, manufacturers of personal and domestic aerosol dispensers are required to perform a hazard analysis to demonstrate they understand the health implications of their products.
This hazard analysis includes assessment - where appropriate - of the risk of spray droplet inhalation and this requires knowledge of the aerosol droplet size distribution, along with the physical and toxicological properties of the formulation.
Mark Hammond, chief executive officer at Melbourn Scientific, said: 'Much of our work in the healthcare arena is aimed at ensuring that particles or droplets are the right size for delivery to a specific area of the respiratory tract.
'For example, we routinely measure nasal sprays to show that the product is targeted to deliver to the nasal cavity and the risk of inhalation is minimal.
'Conversely we routinely perform formulation and testing services for clients who wish to deliver products directly to the lungs.
'The knowledge gained in this highly regulated area enables us to work with clients to ensure tests are best suited to their products,' he added.
Melbourn Scientific is collaborating with Malvern Instruments and Copley Scientific on a series of studies aimed at refining the techniques and technologies available to meet the needs of aerosol manufacturers.
