About

An imidazoline-based surfactant and antistatic agent derived from tallow (animal fat), used in hair care products for conditioning and static reduction.

Tallow Hydroxyethyl Imidazoline (CAS 90411-99-7) is an imidazoline-type amphoteric surfactant derived from tallow fatty acids and hydroxyethyl imidazoline. Imidazoline derivatives are used as antistatic agents and surfactants in hair care formulations. The tallow origin raises ethical/vegetarian considerations but does not represent a safety restriction under EU cosmetics law. Some imidazoline compounds have been subject to review for skin sensitisation potential, and the substance should be used within established concentration limits.
