Rice bran wax-based emulsion for water-resistant coatings

Overview

The rice bran wax-based emulsion offers an innovative solution for creating water-resistant coatings on keratin-rich fibers such as wool, silk, and specialty bio-fibers. This emulsion takes advantage of the natural affinity between keratin's lipophilic surface and the long-chain esters in rice bran wax, providing an effective moisture-repellent barrier without compromising the texture or feel of the fibers. This solution is particularly suited for industries requiring durable and invisible water resistance.

Technical specifications

Key features:

• Utilizes long-chain esters (C46–C66) from rice bran wax for superior adhesion to keratin fibers
• Forms a thin, uniform film that maintains fiber flexibility and softness
• Water resistance measured using COBB values, ensuring high performance in moisture-rich environments
• Formulation tuning for optimal wax-to-emulsion ratios
• Surface characterization using Scanning Electron Microscopy (SEM) to ensure uniformity
• Safety validated through Human Repeat Insult Patch Tests (HRIPT) to guarantee biocompatibility

Technology readiness level

This technology is at TRL 8, indicating that it has been demonstrated in a relevant environment and is in the final stages of validation before full-scale deployment. The roadmap includes pilot scaling, industrial process validation, and quality control measures to ensure consistency and performance.
