Keratin-targeted peptide/small-molecule repair platform

Overview

The keratin-targeted peptide/small-molecule repair platform is designed to address the chemical damage inflicted on keratin fibers by bleaching, heat, and grooming. By leveraging low-molecular-weight keratin-binding peptides or peptide mimetics, this solution enhances fiber integrity through durable crosslinking interactions such as hydrogen/ionic bonds and thiol-disulfide linkages. This platform excludes hazardous crosslinkers, focusing on cosmetic-safe alternatives that penetrate and stabilize porous or damaged fibers.

Technical specifications

Key features:

• Utilizes peptides and small molecules for keratin binding to repair damaged fibers
• Establishes durable crosslinking (e.g., hydrogen/ionic, thiol-disulfide)
• Excludes hazardous crosslinkers, ensuring cosmetic safety
• Compatible with cosmetic pH and withstands repeated wash cycles
• Screening and ranking of candidate chemistries based on safety, mechanism, and formulation compatibility

Technology readiness level

This platform has achieved a Technology Readiness Level of 3, indicating it is in the experimental proof-of-concept stage. It involves analytical R&D support, candidate screening, and validation planning. Future phases of development will refine the platform through testing and co-development with partners.
