AI Technical Summary
Existing technologies struggle to efficiently dissolve hair keratin under mild conditions. Conventional solvents and some eutectic solvents suffer from high dissolution temperatures and high costs, limiting the resource utilization of hair keratin.
Using choline chloride as a hydrogen bond acceptor and ethanolamine, diethanolamine, or N-methyldiethanolamine as hydrogen bond donors, a eutectic solvent is formed. By appropriately mixing these components, hair is dissolved at 60-85 °C, and then treated with a coagulant to achieve efficient extraction of hair keratin.
Under mild conditions, the hair dissolution rate can reach up to 85%, and the extraction rate can reach up to 67%, which reduces production costs, maintains the structural integrity of keratin, and has good potential for industrial applications.
