This ingredient operates as an antistatic agent by neutralizing electrical charges present on surfaces, particularly beneficial for hair to reduce frizz and flyaways. Furthermore, it serves as a hair conditioning agent, facilitating easier combing, imparting softness, smoothness, and shine, while also contributing to hair volume and lightness.

The Environmental Working Group (EWG) rates this ingredient as 'Unacceptable' for their VERIFIED products due to concerns including low neurotoxicity, low endocrine disruption, low-moderate non-reproductive organ system toxicity, moderate respiratory effects, some developmental/endocrine/reproductive effects, and acute aquatic toxicity. Additionally, studies on quaternary ammonium compounds, the ingredient's class, indicate potential effects on cholesterol biosynthesis and neurodevelopment at a cellular level.
