Light-mediated controlled hydrogen peroxide release for hair bleaching
A novel light-activated catalyst generates hydrogen peroxide for controlled hair bleaching, allowing precise localization and intensity adjustment using visible light. Compatible with existing hair care products, it offers enhanced bleaching control and efficiency.
Overview
This innovative solution utilizes a light-activated catalyst to generate hydrogen peroxide from oxygen and a donor molecule under visible light irradiation. The catalyst's ability to be tuned for various wavelengths, including infrared, allows precise control over where and when bleaching occurs. This method can be integrated into hair care products like shampoos or gels, enabling users to achieve desired bleaching results with spatial and temporal precision. Users can adjust the bleaching intensity and area by controlling light exposure, making this a versatile and user-friendly approach.
Technical specifications
- Catalyst Activation: Utilizes a small molecule catalyst activated by visible light.
- Adaptable Wavelengths: Catalyst can be tuned for different light wavelengths, including infrared.
- Localized Control: Light sources such as lasers or screens can localize hydrogen peroxide generation to specific areas.
- Formulation Compatibility: Can be integrated into shampoos or gels, with light exposure converting the gel into hydrogen peroxide.
- Adjustable Bleaching: Concentration of hydrogen peroxide can be controlled through the oxygen and donor molecule concentration.
Technology readiness level
This technology is currently at TRL 3, with ongoing development focusing on optimizing gel composition, catalyst ratios, and suitable light sources. Further studies will determine the ideal conditions for effective bleaching, including exposure time and light intensity.
