Stockholm University researchers have developed a fully biological hair conditioner using lignin gel emulsions, offering a sustainable and environmental alternative to conventional hair products.
Hair conditioners generally contain 20-30 ingredients, many oil derivatives and oleochemicals, which generates concerns about sustainability and environmental impact. A new study published in Scientific advancesIt shows that micellar lignin gels can effectively stabilize emulsions with natural oils, reducing the need for synthetic tension and complex stabilizers commonly used in commercial formulations. The research team, led by Mika Sipponen at the University of Stockholm, sought to explore lignin, a common and renewable component in wood biomass, such as a multifunctional component for hair conditioning.
“Our findings highlight the potential of lignin as a stabilizer in oil emulsions in water, which allows a more natural and sustainable approach to hair conditioning,” says Mika Sipponen. “When using wood derived lignin directly without any chemical modification, we not only simplify the list of ingredients but also eliminate the need for organic solvents, which makes the process more ecological.”
Comparable to commercial hair conditioners
The lignin gel conditioner was tested against a commercial hair conditioner, which shows the stability of the comparable emulsion, viscosity and conditioning performance. A formulation with 6 percent of coconut oil effectively lubricated damaged hair, reducing the humid combination force by 13 percent, as confirmed by means of combination force and analysis of multiscala microscopy. It is important to highlight that the product was easily rinsed from paper and skin with cold water despite its dark color, which demonstrates practical usability.
New opportunities in cosmetics and food
IEVGEN PYLYPCHUK, who has been fundamental in the development of the lignin gel as a versatile platform material, highlights its broader potential: “Our lignin gel technology extends beyond personal care applications. Your unique ability to stabilize Emulsions and interact with various biomolécular opportunities in cosmetics, food, food and even biomedical formulations, offering a sustainable alternative to conventional ingredients. “
This innovation paves the way for the most ecological solutions of hair care that are aligned with the growing demand of consumers of sustainable personal care products. Researchers anticipate a greater exploration of lignin -based formulations for broader applications in the personal care industry.
