Foresight Group has iinvested £1.6 million into The Salford Valve Company, which provides aerosol valves for use with ecologically sustainable propellants, from Foresight Williams Technology EIS Fund.

Salvalco has developed aerosol valve technologies (referred to as Eco-Valves) from original research carried out by Professor Ghasem Nasr of the Spray Research Group at the University of Salford, that enable safe inert gases such as simple fresh air or nitrogen to be used as a propellant in aerosols. This is significantly better for the environment and far safer than conventional propellants, most of which are hydrocarbons. The Company has developed a family of valve designs for a wide range of aerosol products and applications.
