Microencapsulation for controlled release of oxidants
Innovative microencapsulation technology for controlled release of oxidants like carbamide peroxide onto hair fibers, utilizing water-triggered mechanisms for temporary hair adhesion and customizable release rates.
Overview
This innovative solution leverages microencapsulation technology to control the release of oxidants, such as carbamide peroxide, onto hair fibers. The encapsulated particles are designed to temporarily adhere to hair and release their contents when triggered by water. This approach allows for customizable release rates and quantities, making it suitable for various hair care applications. With over 75 years of expertise in microencapsulation and particle design, this technology offers a reliable and precise method for oxidant delivery.
Technical specifications
- Encapsulation Process: Utilizes hydrophobic matrices and functional polymer overcoatings to promote hair adhesion.
- Controlled Release: Water-triggered mechanism ensures precise timing and location of oxidant release.
- Customization: Formulations can be tailored to meet specific release rate and quantity requirements.
- Development Steps: Includes material selection, process optimization, and pilot-scale sample preparation.
Technology readiness level
This technology is at TRL 3, indicating that proof of concept has been demonstrated. The next steps involve process optimization and preparation of pilot-scale samples for client testing.
