Nanocellulose-based eco-friendly hair dye technology
Innovative hair dye technology using nanocellulose hydrogel, hair care acids, and basic dyes to create long-lasting pastel tones with improved durability and eco-friendliness.
Overview
This innovative hair dye technology utilizes nanocellulose hydrogel as a carrier, combined with hair care acids and basic dyes, to create eco-friendly pastel hair colors that last up to four weeks or more. The use of nanocellulose enhances dye adherence and color fixation, while hair care acids aid in dye absorption, ensuring vibrant and long-lasting pastel tones. This solution aims to offer a sustainable alternative to traditional hair dye methods by improving fastness properties and safety.
Technical specifications
- Nanocellulose Hydrogel: Used as a dye carrier, with a concentration range of 0.5% to 2%, enhancing dye adherence and color fixation.
- Hair Care Acids: Includes hyaluronic acid, salicylic acid, lactic acid, lysine, and glycolic acid to maintain correct pH for optimal dye absorption and scalp compatibility.
- Basic Dyes: Utilizes basic yellow 13, basic blue 3, basic green 3, and basic violet 1 for vibrant pastel tones.
- Fastness Properties: Evaluates color fading, bleeding, and washing resistance to ensure long-lasting results.
Technology readiness level
The technology is at TRL 2, with ongoing research focusing on developing a method for optimal acid and dye combinations, application time, and safety assessments to further validate its effectiveness and commercial potential.
About University of Georgia
The University of Georgia is a comprehensive public land‑grant research university serving a large student body across multiple campuses, known for applied scholarship and community partnership. Industry partners access core facilities and pilot‑scale capabilities—including the Food Product Innovation and Commercialization Center—for prototyping, scale‑up, and product validation. A downtown Innovation District and a statewide Cooperative Extension network link campus expertise to companies across Georgia, while proximity to Atlanta’s corporate and logistics hubs lowers barriers to engagement. Research is supported by competitive federal funding from agencies such as NIH, NSF, USDA, and DOE. A dedicated technology transfer office provides IP services, licensing, startup support, and incubator space to accelerate commercialization.
