Croda International Plc (Croda), the company that uses smart science to create high-performance ingredients and solutions that improve lives, confirms the official INCI (International Nomenclature Cosmetic Ingredient) name for its advanced hair repair ingredient, KeraBio K31, Hydrolysed sr-(Tripeptide-137 Hexapeptide-40 sh-Polypeptide-184 sh-Polypeptide-146).
Outperforming the benefits of animal-derived keratin
KeraBio K31 is a novel, bio-based product which is the next step up in hair repair outperforming the benefits of animal-derived keratin. The ingredient, which is designed to repair and strengthen hair, sets a new standard in hair care performance and innovation for the professional hair salon market. The biotech-powered biomimetic bond builder delivers a vegan keratin recharge at the molecular level, elevating hair strength beyond repair.
This pioneering innovation is a great example of close cooperation across Croda’s global R&D, biotech, operations, and marketing teams, supported by key external scientific contributors:
The team at their Biotechnology Research and Technology site, Daresbury, UK, led the creation of the novel keratin structure that met the performance and sustainability specifications.
Additional insights about KeraBio K31’s unique mode of action, particularly its role in forming internal hair bonds, were developed by the UK R&D team, strengthened by data generated in collaboration with trusted external partners, adding depth to our understanding of this advanced technology.
In parallel, their R&D team in the USA delivered robust in-vitro performance data, demonstrating KeraBio K31’s ability to significantly improve hair strength and resilience, validating its benefits in real-world application.
- Supporting the scale-up process, its Process Innovation team brought critical expertise to ensure KeraBio K31 was production-ready at a commercial scale, preserving its integrity and performance in formulation.
Sandra Breene, president of Consumer Care commented, “KeraBio K31 is a strategic response to evolving consumer expectations around efficacy, sustainability, and science-led performance.”
“This launch is the result of extensive collaboration across our global business. By bringing together our innovation, sustainability, and formulation teams, we have developed a biomimetic keratin technology that not only reflects our commitment to pioneering high-performance beauty solutions but also demonstrates how we innovate together to shape the future of hair care.”
