About
Hydroxyethyl Tallowdimonium Chloride is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
This quaternary ammonium compound is derived from hydrogenated tallow fatty acids and hydroxyethyl groups. It functions as an antistatic agent and hair/skin conditioning ingredient. The tallow-derived alkyl chain (typically C16–C18) is well-characterized and considered low in toxicity. It is not individually listed in EU Annex II or III, and standard quaternary ammonium safety limits apply. Typically used at 0.1–3% in rinse-off hair care products.
