Frequently asked questions

Salvalco Eco-Valve is a brand new valve designed to enable aerosols to be propelled successfully by harmless gases such as nitrogen or simply compressed air, while offering a spray performance that is similar to LPG-propelled products. A truly ‘game changing’ achievement, Eco-Valve is a highly versatile and environmentally friendly aerosol solution that can be used in over 85% of aerosol applications offering suppliers and manufacturers the technology of tomorrow, today.

Salvalco Eco-Valves utilises patented Bubbly-Flow Technology developed by the Spray Research Group (SRG) at the University of Salford in the UK. It is this technology that enables aerosols to be propelled successfully by harmless compressed inert gases. Significantly better for the environment, it is also far safer than conventional LPG propellants, which typically are hydrocarbons.

Eco-Valve has been in the market now for a number of years, providing brands with an effective, tried and tested sustainable aerosol solution.

Salvalco is continually innovating and will be bringing out further new technologies in the future.

Consumers love the aerosol format. Less favourable however is the impact LPG propellant and the build up of VOCs (Volatile Organic Compounds) can have on our health and the environment. As such brands and consumers have been increasingly looking for alternatives.

It’s the reason why we have spent years developing our highly innovative aerosol solution powered by nitrogen, while offering all the great performance benefits of traditional valves. Eco-Valve is now being adopted by leading brands worldwide.

The inception of Eco-Valve involved decades of R&D at the University of Salford (UoS) by the Spray Research Group (SRG).  A valve system was designed and developed that would enable an aerosol to be propelled by inert gases (nitrogen). Giving a high quality consumer spray performance.

It’s this research by the SRG, guided by the leadership of Professor Ghasem Nasr that has led to the development of Salvalco Eco-Valve.

Eco-Valves are highly versatile and can be used in a range of application fields including personal care, household, food and industrial.
The technology is also a cost-effective alternative to BOV, offering great performance benefits and a superior spray quality.

Eco-Valve can be filled on conventional aerosol filling lines without the need for significant investment in change parts.

What are the key benefits
of using Eco-Valve?

Each time a Salvalco Eco-Valve is used with nitrogen or air, harmful propellants, VOCs and greenhouse gases are kept out of the environment.

The use of Eco-Valves also offer greater safety and less risk with the potential for aerosols to be categorised as non-hazardous.

The benefits: 

  • Nitrogen has zero Hydrocarbon VOC impact
  • Low quantity of inhalable particles
  • Nitrogen is non-flammable
  • No danger of misuse or abuse

So how do the performance benefits of Eco-Valve compare with more traditional LPG/Butane options and what did consumers say they liked?

The benefits:

  • Preferred the performance to LPG propellant
  • Dry and soft spray
  • Consistent flow and spray performance to the end of the can
  • No gas smell

Eco-Valve also delivers on performance with a number of favourable technical attributes.

The benefits:

  • Can be used across a broad range of aerosol applications
  • Compatible with the use of natural/ organic ingredients
  • Consistent performance throughout the pack
  • Standard filling procedure with only minor modifications to existing lines needed
  • Rapid, continuous R&D improvements to technology


Using Eco-Valve also supports the bottom line too!

The benefits:

  • A more cost-effective solution to Bag-on-Valve (BOV)
  • Using nitrogen is more economical reducing costs across the supply chain (manufacturing, storage, transportation and insurance)
  • Improved profit margin with typically higher final pack price
  • Possibility to increase longevity of pack and increase value to consumer


The use of Eco-Valve is helping to future proof business, enabling companies to remain compliant with industry regulations

The benefits:

  • Future proofing against potential government legislation
  • Meet international and industry targets
  • Supporting the industry to meet government and corporate sustainability goals
