Reinventing UV protection from agricultural waste.

CARDASUN develops novel bio-based UV absorbers from cashew nut shells.

One technology platform.
Multiple applications.

Our bio-based UV absorbers are designed for applications across Personal Care, Plastics & Coatings, and Agrochemistry.

Personal Care

UV protection for skin and cosmetic formulations, with important applications in anti-aging skincare.

Under pressure.

UV protection is more important than ever - but the chemistry behind it is under pressure.

Several widely used legacy UV filters are facing increasing regulatory scrutiny.

More and more regions ban certain UV filters for environmental concerns

Petrochemical dependency for organic UV filters creates risk

Our Vision.

We make high-performance UV protection biorenewable and safe

Circular & Biorenewable

We turn agricultural waste into a renewable source for petrochemical-free UV actives.

Safety by design

We develop our molecules with human and environmental safety at the core.

Local value creation

We promote the production where our renewable raw material originates.

01.

What is the difference between organic, mineral and bio-based UV filters?

Conventional organic UV filters are produced from petrochemical feedstocks, while mineral UV filters rely on mined resources such as zinc and titanium. Both depend on finite resources. Bio-based UV filters use renewable biological feedstocks instead, offering a new route to high-performance UV protection.
