Understanding the technology, sensory effects and health benefits of aerosols can make a company truly trendsetting, writes Joanne Hunter


Trendsetting companies understand the art of spray and the art of foam, technical and organoleptic constraints and the relationship between texture and taste and texture and palate. The mouth can enjoy bubbly, light, rich and smooth among a multitude of sensations. While in healthcare, aerosols have a serious role to play helping to make lives better.

The Aerosol Forum event from 9-10 March in Paris will reflect the immense breadth and reach of an ever-advancing technology. The sector’s sustainable development, its moves in healthcare and the inventiveness of the food industry in finding new applications will be among the key talking points.

The French institute for food research IRFAQ provides expertise in developing formulations. Its aerosol know-how stirs the imagination of food producers, as delegates will hear.

To illuminate technological advantages and potential of the aerosol in the food category, organiser Oriex is featuring the Paris Aerosol Restaurant with a tasting session led by a professional French chef to demonstrate how aerosols add to the presentation and eating experience of dishes.

Aerosol systems can spray and dispense pure water, olive and canola oils, and deliver from light and foamy espumas to highly viscous products such as honey, cheese and liver pâté. LindalAerosol says aerosols that double up as a kitchen utensil offer consumers the convenience of adding comfort and saving time in the kitchen: a can of whipped cream avoids hand mixing, for example.

Polenghi – Coltivia is an aerosol food product research and packaging unit whose products are manufactured under client brands and distributed in Europe and the USA. Its director, Edoardo Ruga, says in many instances when an aerosol is built into the concept of the product it provides for safety and a long shelf life for the finished product, without heat treatment, and aerosols retain these inherent advantages ‘from first to last use’.

The conventional approach can be used whereby the propellant is mixed with the product; or the dual compartment aerosol (bag or piston), which separates the propellant and product.

Adaptations of aerosol lines to food products must account for a humid environment, cleaning, aseptic conditions, frequent and quick dismantling, and flexibility and versatility, says Mr Ruga. Anti-bacteriological contamination packaging technology in many instances can replace post-pasteurisation, he adds.

Appetites grow incessantly for cost-effective aerosol cans. In cost performance analysis various technologies using steel and aluminium offer operating windows that makers may switch between to benefit themselves and their customers, claims Mall+Herlan. The manufacturer of complete lines for aerosol production says it can help reap the advantages of using recycled aluminium and lightweighting to improve the carbon footprint.

Plasticum, of The Netherlands, will join these Forum speakers, taking as his theme ‘green aerosol sprays’, touching on smart technologies, optimised production, recyclability and savings.

The worlds of aerosols and pharmaceuticals are closely linked. Delegates will hear how many treatments based on the spraying of extremely small particles are combining state-of-the-art technologies with increasing ease of use, to make life simpler and improve the compliance of patients in all age groups.

In cosmetics and pharmaceuticals it is essential to characterise and to predict realistically the performance throughout the life cycle of a product, says Dr. René Bommer, of PharmAccel Consulting, in Germany. Various physical parameters define the quality of an aerosol cloud. In addition, the possible interaction between the substrate materials in the device and the respective formulation can alter the performance over time.

ColepCCL has introduced an application system that allows for powerfully boosted vaporised, liquid or gel formulae, using bag-onvalve technology. Known as Wings, it controls actuation into the user’s mouth or hand without the need to pump. Due to its targeted functionality the system ‘perfectly’ fits nutrition, oral care and pharmaceutical healthcare applications, says ColepCCL.
