Ph sensitive film formers for enhanced active retention in haircare

Overview

The proposed solution involves the development of advanced pH-sensitive film formers designed to effectively retain active ingredients in haircare products. These film formers are particularly advantageous as they remain insoluble at high pH levels, thereby enhancing the contact time of oxidants and reducing active ingredient run-off. This results in improved deposition on hair fibers, leading to enhanced hair softness and shine, providing a superior consumer experience compared to traditional methods that may involve microencapsulation.

Technical specifications

This technology leverages positively charged film formers that are insoluble or have reduced solubility in high pH environments. The film formers are designed to be cationic, promoting strong fiber substantivity through electrostatic interactions. Key features include:

• High-pH-insolubility: Reduces active ingredient migration and run-off during alkaline processing.
• Electrostatic enhancement: Improves the deposition of active ingredients on hair fibers.
• Compatibility: Compatible with oxidative systems and a variety of active ingredients.
• Cost-effective: Offers a cheaper alternative to microencapsulation, avoiding microplastic regulations.

The development process involves screening various candidate film formers based on their charge density, molecular weight, and cosmetic acceptability. Characterization involves run-off testing on treated hair swatches, surface charge analysis, and compatibility assessments with oxidative treatments.

Technology readiness level

This technology is currently at Technology Readiness Level 2, indicating that initial research and screening of candidate film formers are underway. Further validation and development are planned to advance the technology towards commercial application.
