Event Details


There is an ever increasing demand for effective formulation and efficient product development. A deeper understanding of the role of surfactants will help in meeting these demands.



This is an advanced course and provides an overview of surfactants, including their functions and applications, at a more in depth level than the “An Introduction to Surfactants” course.



Chemists and technologists with a working knowledge of surfactants and surface chemistry.


The course tutor is Dr Bob Hefford who has many years’ experience in surface and colloid chemistry working for Unilever and Bristol-Myers Squibb where he was Director of their EMEA R&D laboratory. His responsibilities included both basic research and product development. Bob now runs an independent consultancy offering advice on advice and direction on colloid science, cosmetic science, formulation and regulation. He maintains an on-going interest in education particularly in the area of surfactant science.


Feedback from those attending previous courses includes:


‘The correct depth of information was supplied - very clear and concise’; ‘Good starting point to surfactants’; ‘It was good, well presented, thought out, etc’; ‘The presentation and explanation meant the course was very easy to understand’

‘I found the content just right as it covered everything I personally work on. The tutor was excellent’

‘The delivery and knowledge of the speaker was excellent - involved people in a positive manner’; ‘Very informative and relevant’


BACS members are offered priority booking with attendance limited to 20 delegates to ensure that the course is interactive. Attendees will receive both electronic and a hard copy of the course material.




Registration and refreshments




Introduction to fundamentals:


- What is a surfactant? (functional names, structures, major   categories)


- Micelle formation (what a micelle is, morphology, critical micelle   concentration (CMC), factors affecting CMC)


- Phase and phase diagrams (rheology, typical phase diagrams, basic   aggregate types)


- Solubilisation


- Precipitation (hardness tolerance)


- Wetting (contact angles)


- Adsorption at gas/liquid and solid/liquid interfaces (importance,   mechanisms)










- Foams and defoaming (what a foam is, why foams are important,   defoaming)


- Emulsions and microemulsions (importance, definitions, mechanisms,   role in detergency, demulsification)


- Dispersions (role in stabilisation, rheology, importance of   adsorption)


- Detergency (role of surfactant types)


- Examples of practical formulations
