Croda unveils new data for Crodabond™ CSN: effective SPF boosting for high performance sun care

3 November 2025: Croda International Plc (“Croda”), the company that uses smart science to create high-performance ingredients and solutions that improve lives, has recently unveiled new SPF-boosting data for Crodabond™ CSN.  

Already established in Croda Beauty’s hair care portfolio, Crodabond CSN is a 100% naturally derived emollient proven to provide long-lasting cuticle sealing and split-end repair for damaged hair. New data reveals its ability to enhance the efficacy of both organic and inorganic UV filters, offering a cost-effective solution to achieve high SPF claims.  

This ingredient boosts SPF and UVA protection by up to 111% by improving film formation, UV filter distribution and speadability on the skin. By facilitating the use of less UV filter, it enables formulators to create sunscreens with lower environmental impact, without compromising on performance or sensory aesthetics.  

Hannah Critchley, Head of Marketing - Skin Care, Croda Beauty, said: "At a time where consumers are looking for science-backed beauty products, our latest data for Crodabond CSN embodies that principle, helping brands create sun care formulations that deliver consistent, proven protection through enhanced film formation and optimised UV filter distribution. Creating reliable sun care formulations that consumers trust is ever more important with increased scrutiny of SPF testing practices.”   

At Croda, we believe that true innovation goes beyond efficacy, it builds trust. We are committed to helping our customers create the next generation of sustainable, high-performance sun care solutions. By improving SPF performance and reducing the amount of UV filter requires, this biodegradable SPF booster supports formulation efficiency while helping to cut the carbon footprint of sunscreens containing inorganic UV filters by up to 13.5%.  

At Croda, we are always striving to meet customer demands and with growing consumer awareness of the dangers of sun exposure driving desire for high performance products, this innovation provides a proven solution that combines reliable performance, natural credentials, and sustainability benefits in every formulation.
