Do you have a novel, more efficient technique for turning our liquids into free-flowing powders?


AkzoNobel Specialty Chemicals produces various products in the liquid phase which are supplied to the market as a powder. For many applications our customers require these products to be dry, non-hygroscopic, and free-flowing.

Examples of these products include:

  • Powders which are dried emulsions that can be redispersed in water, restoring the product properties of the original liquid
  • Chelates and micronutrients which are used in applications such as household cleaning and agriculture
  • A range of personal care products 

The performance and ease of handling of these materials are highly dependent on the drying process. These drying processes include techniques like precipitation, crystallization, and spray drying.

Converting a liquid to a powder often involves multiple process steps in order to get the desired properties. Final product properties depend on structure, particle size, and particle shape. Given increasing demand for more advanced product technology, traditional drying techniques no longer provide the complete answer and we need new approaches to keep meeting the needs of our customers.

Issues to consider

We are looking to further optimize our drying processes in terms of waste, energy, storage stability of the powder, and sustainability. We are also open to radically new approaches. Irrespective of the drying technique used, final products need to meet certain specification and performance criteria after drying, such as bulk density, particle size distribution, and flowability.

What are we looking for?

We are looking for solutions that fit a range of technologies that we can use to make the production of our dry powder products more efficient. The technology should cover one or more of the following aspects: crystallization control, particle size and shape control, or particle hygroscopicity control.

Both process and chemical modification approaches are in scope, provided they are cost-effective.

What are we NOT looking for?

We are not looking for new suppliers of standard drying technologies.


  • Contribution to sustainability: energy saving or contributing to our no-waste vision; chemical solutions should contribute to the sustainability profile of the end product
  • Economically feasible and capable of being retro-fitted to existing facilities
  • Fit to current AkzoNobel Specialty Chemicals technologies and markets
  • Impact of the idea in the short term (revenue, quality, scalability, time to market, etc.); technology should be ready to be implemented  on a large industrial scale within 2 to 3 years 
  • Quality and maturity of the team
