Croda unveils breakthrough data for KeraBio™ K31: Biotech-driven hair repair with exceptional potency

20 October 2025: Croda International Plc (“Croda”), the company that uses smart science to create high-performance ingredients and solutions that improve lives, is proud to announce breakthrough new data demonstrating the exceptional efficacy of KeraBio™ K31, its next-generation biomimetic¹ hair repair ingredient. 

Built on over 15 years of proteomics² research, KeraBio K31 harnesses the power of biotechnology to act as a vegan keratin recharge at the molecular level, rebuilding and strengthening hair beyond conventional repair. The new data reveals that KeraBio K31 delivers full efficacy at just 0.05% active inclusion, while higher concentrations can provide even greater results, giving formulators flexibility to design high-performance products with lower active use, supporting reduced environmental impact.  

This innovation has just been shortlisted for the Product Innovation Award at the BBIA Demeter Awards 2025, highlighting Croda’s leadership in advancing sustainable, bio-based technologies that combine exceptional performance with environmental responsibility. The winners will be announced at the Royal Society of Chemistry, London, on 17 November 2025. 

Stephanie Neplaz, Head of Hair Category at Croda Beauty commented: "KeraBio K31 continues to redefine what’s possible in hair repair.  Its remarkable potency enables formulators to develop products that deliver superior results while using less active ingredients. It sets a new benchmark in biomimetic bond building technology and delivers a step-change in what we can now offer our customers to elevate hair health and sustainability." 

KeraBio K31 has had the following performance backed by science³: 

• Repairs bonds within the hair
• Delivers 100% stronger hair than the leading bond builder
• Performance improves with continued use
• Resets to virgin hair profile

KeraBio K31 is 99% naturally derived (ISO 16128), vegan-suitable, biodegradable, phenoxyethanol-free, and EU/UK REACH compliant. With this breakthrough data, Croda Beauty continues to set new standards in sustainable, high-performance hair care innovation. By uniting biotechnology and biomimicry, KeraBio K31 represents a new era in molecular hair repair, where advanced science meets environmental consciousness.  

¹ Biomimetics is defined as the imitation of biological processes or models from nature to address complex biological problems, such as material characterisation.  

² Proteomics is the study of the interactions, function, composition, and structures of proteins and their cellular activities.
