E-learning - Impact F online colloid training
 

 

 

 

If ongoing training and development is required, Impact F offers comprehensive web-based colloid science training comprising interactive in-depth learning modules for individual or company-wide continuing professional development.

 

 

Features of Impact F include:

  • Over 1500 web pages of online training
  • Engaging content, including interactive questions, experiments and simulations
  • Structured, yet flexible training that is also available for use as a reference resource
  • Expert authors

Examples of the e-learning modules are summarised below:

Optimising product stability

Formulation science involves the bringing together of many ingredients in order to fulfil the ultimate performance requirements of a product.  Often there is an active ingredient that needs to be delivered to a target site and the formulation must deliver this active in its required form, without disrupting its performance and while maintaining overall product stability. Instability of a product might be displayed by separation of components, creaming, sedimentation, aggregation, coalescence, oxidation or microbial attack.

The shelf life of a product needs to be determined in order to ensure quality and reproducibility of product. Identifying the key factors of product instability and devising appropriate shelf life tests is a major component of this module.


Surfactant chemistry and architecture

Surfactants in a formulation might act as a surface tension modifier or wetting agent, dispersant, emulsifier, structuring agent or it might be in the formulation as a key active ingredient such as in a detergent formulation. This module discusses the classification of surfactants, how they assemble in structures and how chemistry is key to their function.


Emulsion and microemulsion technology

Emulsions are used in many applications as a delivery system. They require mechanical energy to be formed and are stabilised by surfactants and polymeric dispersants to reduce the interfacial tension between oil and water, which lowers the energy of formation. They undergo several destabilising mechanisms which affect the shelf life of emulsion based formulations. Microemulsions form spontaneously given the correct mixture of surfactant, oil and water. They are more stable than emulsions and offer the formulator a number of different options. The choice of surfactant is critical when designing a microemulsion system.


Using dispersants in formulations

In order to stabilise a colloidal dispersion it is possible to use additives such as surfactants or polymeric dispersants or stabilisers. These stabilisers protect the dispersion from aggregation due to the balance between the affinity of the polymer with the particle and the solvent. This module looks at the classification of different dispersants, the decisions that need to be made when choosing an appropriate dispersant, how those dispersants should be added to the formulation and how that might affect the properties of the formulation.


An introduction to practical rheology

Liquid formulations experience many different flow conditions in their production and end-use lifetime.  In order to understand how a formulation will behave under these conditions we need to understand its rheology.  Dispersed colloidal systems behave differently to simple liquids, and this is due to the interactions between the components.  Being able to link an understanding of these interactions with a study of the rheology is extremely important in optimising the performance of a formulation.
