Applications and Industries
Microfoams are important materials to a range of industries. The TLT Foamer technology may offer a new sustainable approach for products, devices, materials, and processes.
Foods and Beverages
Whipped and aerated foods and beverages can offer the consumer indulgent and rich textures, as well as visual quality cues. These products are very familiar to us, such as whipped cream, foamed soda toppings, mousses, coffee crema, and latte milk foams.
However, foods microfoams might also be used as structuring agents and fat mimetics in products that would not normally be foamed. An example of this would be a foamed low fat formulation of a dressing traditionally high in fat e.g. Ranch or Caesar salad dressing. The microfoam structure may add a rich mouthfeel and viscosity usually associated with high fat recipes.
Whipped and aerated foods and beverages are most commonly produced by mechanical whipping, or via the use of nitrous oxide. The TLT foamer may offer a simple and sustainable method of generating foods and beverage microfoams on demand from aerosols, devices or in manufacturing.

Medical and Healthcare
Cleaning, Sanitizing, and Home Care
Foams, especially high stability microfoams, are favorable formats for dispensing cleaning, sanitizing, and decontamination products. Such products include surface and carpet cleaners, hand sanitizers, and large scale decontamination formulations used in disease and infection control.
Stable microfoams allow the user to visualize where and how much of a product or formulation has been dispensed and applied to a treatment area. This is important for product efficacy. The stability of the foam may increase the efficacy of a sanitization or decontamination treatment by allowing a slow collapse of the foam, extending the contact time of active ingredients.
The TLT Foamer is suitable for integration into refillable pressurized sprayer systems, as well as single use aerosol formats. It can also produce liquid microfoams with high stability due to the resulting foams having a low polydispersity (narrow bubble size range).
Liquid microfoams are already used in agricultural and horticultural applications. Microfoams allow small doses of active compound to be applied to target plants, or a specific part of a plant, such as a growing tip. The structure of the microfoam allows it to remain limited to the area of application, unlike sprays which may suffer overspray, drift, or drainage away from the intended site of treatment. For similar reasons microfoams are used for control of pests e.g. ant and wasp nests.
The TLT Foamer technology can be used in existing applications, dispensing high quality microfoams from aerosol packaging, and pressurized hand application systems. However, the design of the TLT Foamer makes it suitable for implementation in nozzles, and could therefore be used to continuously produce streams or sheets of foams from larger application systems such boom sprayers. This flexibility means that the TLT Foamer may offer more sustainable methods of applying agrochemicals, or facilitate the development of new products or completely novel approaches to crop protection and management.
Foams have a diverse range of applications in the industrial sector. The materials properties of microfoams, be they liquid or solid foams, allows them to carry out a broad range of functions from the suspension and distribution of active ingredients, to noise dampening, and insulation. The kinetics of many multi-phase industrial processes, such as gas scrubbing, gas-liquid reactions, and absorption may be enhanced by increasing the interfacial surface area by the formation of microfoams. Hence, the use of microfoams in fire suppression, gas scrubbing, insulation, separation processes, decontamination, and functional materials.
The TLT-Foamer, with its ability to generate microfoams, may offer process and materials advantage in a range of industrial applications.
