Liquid foam: measurement, formulation, R&D, innovation, industrialization

Liquid foams are complex systems formed by gas bubbles dispersed in a liquid. Widely used in many industrial sectors – food, cosmetics, pharmaceuticals, chemicals, materials – they play an essential role due to their texture, stability, visual appearance, and functional performance.

Fragile by nature, they are strongly influenced by the formulation, surfactants or stabilizers, process conditions and the environment. Foam also sometimes appears undesirably.

Rheonis services around liquid foams

Rheonis supports its customers in understanding and optimizing liquid foams through a comprehensive approach:

• Measured : characterization of stability, texture, density, size and distribution of bubbles, viscosity and rheology of foams.
• Studies and modeling : analysis of dynamic behaviors (drainage, coalescence, collapse), interactions between formulation and process, prediction of lifespan.
• Development and innovation : formulation of foams suitable for industrial use or final product, optimization of expansion and packaging processes.
• Training and transfer : support for R&D and production teams to better master the science of foams.

Specific measurement and methods

Among the analyses implemented on liquid foams, Rheonis uses advanced approaches:

• Stability and drainage analysis (phase separation kinetics).
• Texture and consistency measurement (compression and penetration tests).
• Rheology and viscoelasticity mosses.
• Bubble size distribution by imaging and optical methods.
• Apparent density measurement and evolution over time.

Industrial applications

Mastering liquid foams is crucial in many areas:

• Food : whipped creams, dessert mousses, airy breads and pastries, sparkling drinks.
• Cosmetic : cleansing mousses, styling mousses, airy sensory textures.
• Pharmaceuticals and health : controlled release formulations, topical medical foams.
• Materials and Chemistry : insulating foams, foaming agents for polymers and lightweight concrete.
