At Colworth, we are pioneers in industry-leading safety and sustainability science and in developing ice cream and iced tea innovations to delight consumers.

Today we are part of a dedicated science park situated in the scientific heart of the UK within the Oxford-Cambridge Arc that is home to many of our strategic suppliers and university partners.

This means we have access to some of the world’s smartest minds and skillsets in one location. And that agility and collaboration makes us an engine for R&D innovation that attracts global scientific talent to work with us.

An ecosystem nourishing progress


More than 40 companies and universities have a presence at Colworth Science Park including: Symrise, Bedfordia, chocolate specialist Barry Callebaut and Cranfield University. And Unilever R&D’s welcoming approach to open innovation has seen a growing number of collaborations driving product innovation forward.


Working jointly with Barry Callebaut, for example, led to the development of a new ‘dippable’ golden caramel chocolate that was a launch selling point of Magnum Double Gold Caramel Billionaire.

It’s also seen suppliers such as Firmenich, who work with us on flavour tonalities, move its UK operations to Colworth to foster closer links and work together on new opportunities.


We are also fortunate to be located within the Oxford-Cambridge arc and the Midlands Engine Catchment which gives us access to talent and partners beyond the sites environs that offer services including prototyping, engineering, scouting, sample production, 3PM audits and regulatory support.
