Croda has confirmed the official INCI (International Nomenclature Cosmetic Ingredient) name for its biomimetic hair repair ingredient, KeraBio K31.
The INCI name is Hydrolysed sr-(Tripeptide-137 Hexapeptide-40 sh-Polypeptide-184 sh-Polypeptide-146).
KeraBio K31 is a novel, bio-based product said to outperform the hair repair benefits of animal-derived keratin.
The 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 Croda’s 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 its understanding of this advanced technology.
In parallel, Croda’s 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, Croda’s 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, said: “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.”
