Summary on Grant Application Form |

This proposal is part of the ENVIROSPRAY' LINK proposal, led by Lionstar and Reckitt and Benckiser (the largest manufacturer of Household and Personal Care Aerosol products in the UK). Novel Lionstar manufacturing technology permits very complex one-piece internal actuator and nozzle designs to be mass produced, but with cost savings over conventional aerosol actuators/nozzles. Using this technology the use of internal flow control devices has been proven, by the proposers, for the maintenance and improvement of two formats of household aerosol, with greatly reduced content of butane propellant. This project will extend these concepts to the more challenging case of completely VOC-free aerosols, propelled by finger/trigger pumps, for which spray quality must be greatly improved over what is currently possible, but without significantly increasing manufacturing cost. The UMIST responsibilities towards this and are, (a) design and model making of (perspex) pre-prototype actuator nozzles, incorporating flow-control devices, (b) testing these designs for spray pattemation, consistency with time and drop size (using PDA and other laser instruments), and (c) utilising computational fluid dynamics as a design aid for the flow control devices. This programme will be applied with the aim of replacing at least three of the VOC-containing product formats of Reckitt and Benckiser. In addition to this work on actuator/nozzle designs, new pump formats will be developed by Llonstar, and these will be tested for flow rates, pressures, actuation force and consistency, as part of the MIST contribution.
