The research work is showcased in the film, with external experts – including Dr Timothy E H Allen of the University of Cambridge Toxicology Unit – recognising Unilever’s contribution to furthering international confidence in non-animal testing methods.

The film premiered in June at the virtual Cosmetics Europe Trade Association’s industry event. It is one of 24 films created for the Essentials for Daily Life series, produced by BBC StoryWorks, which offer a behind-the-scenes view into how the often-overlooked cosmetics and personal care sector is enhancing people’s lives, supporting the planet and improving products.
