Croda has announced new data demonstrating the efficacy of KeraBio K31, a next-generation biomimetic hair repair ingredient that uses biotechnology to act as a vegan keratin recharge.
According to the company, the data reveals that KeraBio K31 (INCI: Water (Aqua) (and) Hydrolyzed sr-(Tripeptide-137 Hexapeptide-40 sh-Polypeptide-184 sh-Polypeptide-146)) 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.
Key Hair Repair Benefits
According to the company, KeraBio K31:
- Repairs bonds within the hair,
- Delivers 100% stronger hair than the leading bond builder,
- Improves with continued use and
- Resets to virgin hair profile.
Stephanie Neplaz, head of the 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."
Biomimetic Bond Building
Neplaz added that the ingredient sets a new benchmark in biomimetic bond-building technology and delivers a step-change in what Croda can now offer customers to elevate hair health and sustainability.
KeraBio K31 has reportedly been shortlisted for the Product Innovation Award at the BBIA Demeter Awards 2025, which highlights leadership in advancing sustainable, bio-based technologies. The winners will be announced at the Royal Society of Chemistry in London on Nov. 17, 2025.
