Wool-derived porous polymer for controlled fragrance release

Overview

The wool-derived porous polymer is an innovative solution for controlled fragrance release, leveraging biodegradable keratin particles sourced from pure New Zealand wool. This technology addresses the need for sustained scent intensity in personal care products. By integrating fragrance into the porous structure of keratin particles, the polymer provides a dual function: high-capacity fragrance reservoir and a diffusion regulator. This results in a smooth skin feel and consistent delivery of fragrance, enhancing user experience in ointments, creams, and roll-on applications.

Technical specifications

Key features:

• Porous keratin particles: Derived from New Zealand wool, these particles are small (10-20 µm) and possess a high surface area, supporting efficient fragrance absorption (~150 g/100 g) and release.
• Compatibility: The system is compatible with various formulations, including ointments, creams, and roll-ons, due to its stability and smooth application.
• Biodegradable: The use of natural keratin ensures that the polymer is environmentally friendly.
• Fragrance retention: The technology has demonstrated superior scent retention in previous applications, like fabric softeners, maintaining intensity for over a week.

Technology readiness level

This technology is currently at TRL 6, having been validated in relevant environments with a focus on formulation stability and fragrance retention. Future validation steps include prototype formulation, stability testing, sensory evaluations, and scale-up feasibility for commercial production.
