Triethanolamine-modified poloxamer temperature-sensitive hair care gel for intelligent controlled release of sodium thioglycolat

Abstract A triethanolamine-modified poloxamer temperature-sensitive hair care gel was formulated in order to reduce the adverse health effects associated with sodium thioglycolate (TGA(Na)), the active component in hair treatment agents, while maintaining excellent efficacy. It was found that TEA-3 gelled at 32 °C with a triethanolamine concentration of 3 %. This formulation exhibited a reversible phase transition, transitioning to a solid state upon contact with the scalp (>32 °C) and reverting to a liquid state when in contact with hair (<32 °C). The release behavior of TGA(Na) from the gel was assessed by both in vitro release studies and transdermal experiments. In addition, it was observed that the triethanolamine-modified poloxamer gel exhibited improved hair care efficiency compared to conventional hair care agents. These results suggest that the triethanolamine-modified poloxamer gel is a promising alternative to conventional hair care products, offering improved efficacy while minimizing potential adverse health effects.
