Kew’s work with Procter & Gamble
Working together with Procter & Gamble (P&G) we’re using our world-class scientific knowledge and expertise to identify and authenticate key botanical ingredients in consumer products.

We're combining plant expertise and phytochemistry knowledge, use of Kew’s extensive living and dried collections, with the product expertise and performance testing methods of P&G. This allows us to collaborate on a joint vision to explore new and innovative ways of using botanical ingredients to create products for the future, for example those with antioxidant, antibacterial and moisturising properties.
