The European Commission’s (EC) Scientific Committee on Consumer Safety (SCCS) has adopted an opinion in relation to the EC’s request for clarification of the meaning of the term ‘sprayable applications/products’ used in three nanomaterial-related opinions. The Committee is accepting comments on this opinion until 10 November 2014.
The request from the EC was made earlier this year, and the terms of reference were:
- ‘In light of the different definitions of spray [used], could the SCCS clarify the product types included in the term ‘sprayable applications/products’ used in the conclusions of the safety assessments for the nano forms of Carbon Black CI 77266, Titanium Oxide and Zinc Oxide?
- For clarity of the future safety assessments, could the SCCS adopt a harmonised terminology that will allow a distinction between aerosol (with propellant), spray (spray bottles) and pump dispensers (single-dose creams)?’
Experts in the SCCS determined that ‘the term ‘spray’ or ‘sprayable’ will mean that a formulation is either dispensed by the use of propellant gas as defined in Directive 75/324, or by a spray bottle with a pump dispenser that forces a liquid through a nozzle generating a spray stream or a mist of a liquid…the term ‘pump dispenser for dosing cream’ will mean a formulation is dispensed through a mechanical pump in the form of a single dose, where the process does not generate a significant quantity of airborne particles or droplets that are either respirable as such, or become respirable as a result of drying while airborne’.
The scientific committee then used this harmonised terminology to make changes to the three definitions for nanomaterials. In most cases it was used to clarify that the Committee meant ‘spray applications that might lead to exposure of the consumer’s lungs to [nanomaterial] nanoparticles by inhalation’.
