What Makes KeraBio™ K31 Different
Developed by Croda’s biotechnology division, KeraBio™ K31 is a bioengineered keratin fragment that precisely replicates the amino acid sequence of the human hair keratin protein K31, one of the key structural components responsible for strength and resilience in healthy hair.
Unlike traditional hydrolyzed keratin, which sits on the surface of the hair fiber, KeraBio™ K31 targets damaged sites at the molecular level, bonding to restore integrity and rebuild strength from within. The result is true biomimetic repair, visible after the first use.
The Science Behind the Shine
Using recombinant protein technology, Croda engineered KeraBio™ K31 to have high bioaffinity to the hair cortex, allowing it to integrate seamlessly into the damaged keratin structure. In testing, KeraBio™ K31 has demonstrated:
- Up to 80% recovery of tensile strength after chemical or heat damage
- Enhanced elasticity and flexibility, reducing breakage
- Improved shine, softness, and manageability with continued use
This precision engineering represents a major step forward in the science of hair restoration—offering formulators a high-performance, sustainable, and biotech-powered alternative to traditional protein treatments.
DMI Solutions: Now Creating Prototypes using KeraBio™ K31
At DMI Solutions, our formulation and innovation teams have begun working with KeraBio™ K31 to develop concept formulas that showcase its unique performance and sensory benefits. From bond-repair masks and leave-in creams to protective styling and overnight repair treatments, we’re pushing the limits of what’s possible with this new ingredient technology.
We’re also exploring synergistic blends with botanical actives, ceramides, and amino acid complexes to create complete repair systems that target both fiber and scalp health.
We invite beauty and haircare brands to partner with DMI Solutions and explore how KeraBio™ K31 from Croda can power their next breakthrough product. Whether you’re developing a high-performance salon line, a clean biotech brand, or a skinification-inspired hybrid concept, our team is ready to collaborate and bring your vision to life.
Connect with our R&D and innovation teams to explore prototype formulas, discuss custom applications, or schedule an innovation session focused on your brand’s unique positioning.
