Enquiries Eden Research plc 01993 862761 Clive Newitt, Managing Director St Helens Capital Partners LLP 020 7368 6959 Mark Anwyl Notes: Eden's strategy is focused on the development and commercialisation of its terpene-based encapsulation technology for agricultural and non-agricultural uses through appropriate regional or global partnerships. Terpenes are natural compounds which function as defence mechanisms in many plant groups and are released in response to infection, attack by pests, stress or mechanical injury. Terpenes are already widely used in the food flavouring, cosmetic and pharmaceutical industries. Historically, terpenes have had limited commercial use in the agrochemical sector due to their volatility, phytotoxicity and poor solubility. Eden's platform encapsulation technology provides the unique, natural solution to these problems and enables terpenes to be used as effective, low-risk agrochemicals.
