Liquid foams and emulsions: generation, stability and properties
Technicians, engineers and researchers working in the pharmaceutical or cosmetic sector, food industry, household care products, optimisation of solid foams, etc.
- Acquire fundamental physicochemical concepts related to the generation of foams and emulsions, their structure, stability, and macroscopic properties (including rheology).
- Develop a comprehensive, multiscale understanding of liquid foams and emulsions.
- Become familiar with key techniques for generating and characterizing interfaces, thin films, foams, and emulsions.
- Understand and manage the interplay between physical and chemical parameters in foam and emulsion systems.
- Build effective problem-solving reflexes for diagnosing and addressing issues involving foams and emulsions.
Day 1: 10:00 to 17:30
- Introduction (Training, teachers, and participants)
- Properties of gas/liquid and liquid/liquid interfaces
- Surfactants at interfaces and in thin liquid films
- Generation of foams/emulsions
- Practicals
Day 2: 09:00 to 17:30
- Structure of foams/emulsions
- Stability of foams/emulsions & antifoams
- Practicals
Day 3: 09:00 to 16:00
- Rheology of interfaces and of foams/emulsions
- Practicals
- Optimisation of foams/emulsions by formulation
- Open exchanges
Topics covered in the Practical sessions (groups of 3-4 participants):
- Techniques for measuring interfacial tension and interfacial rheology
- Techniques for the generation of foams and emulsions
- Characterisation techniques of individual films at the bubble / drop scale
- Characterisation techniques for foams/emulsions (imaging, conductimetry, rheology)
The participants should have at least a bachelor in chemistry, physics or related subjects.

Each training day includes approximately two-thirds of theoretical lectures, supported by numerous demonstration experiments. The remaining third is devoted to hands-on laboratory practicals, carried out in small groups of 3–4 participants, formed according to participants’ backgrounds and interests.
A binder and a course material will be provided to the trainees.

This training is designed as an upskilling and competency-development program.
Participants will receive an attendance certificate upon completion.
A final evaluation is carried out to measure participant satisfaction and the achievement of the training objectives (knowledge, skills, engagement, confidence), in accordance with Levels 1 and 2 of the Kirkpatrick model for training effectiveness.
