TALLOW HYDROXYETHYL IMIDAZOLINE.

Insufficient Data CAS 90411-99-7 / ANTISTATIC, HAIR CONDITIONING, SURFACTANT - CLEANSING

Tallow Hydroxyethyl Imidazoline serves as a versatile ingredient in personal care, primarily functioning as a surfactant to facilitate the mixing of oil and water, essential for effective cleansing. It also imparts antistatic properties and acts as a hair conditioning agent, contributing to the overall performance of cosmetic formulations.

Science

Mechanism of Action

This compound reduces the surface tension of liquids, enabling the emulsification of oil and water. This action is crucial for cleansing, as it assists in lifting and washing away fat and soil particles from skin surfaces. Beyond detergency, it also provides wetting, film-forming, and emulsifying benefits.

Stability

Optimal stability and performance are achieved when the ingredient is protonated with an acid, demonstrating superior stability within a strongly acidic pH range of approximately 1.5 to 4. Solubility can be modulated: salting with lower molecular weight acids enhances water solubility, while longer chain organic acids improve oil solubility.

The Cosmetic Ingredient Review (CIR) has not yet evaluated Tallow Hydroxyethyl Imidazoline. While concentrated forms of related long-chain alkyl hydroxyethyl imidazolines are classified under GHS as corrosive to skin and eyes, these substances, when diluted for cosmetic applications, exhibit low acute dermal toxicity. They are not anticipated to be skin sensitizers or genotoxic. The US FDA generally deems tallow derivatives safe regarding infectious agent transmission.
