Science
Mechanism of Action
This compound primarily functions by neutralizing electrical charges on surfaces, thereby reducing static and promoting hair manageability. As a conditioning agent, it forms a protective layer around the hair cuticle, which aids in locking in moisture, resulting in smoother, softer hair with increased shine and reduced susceptibility to breakage and split ends. Its application is specifically noted for hair, not skin.

Safety
Safety Profile
This ingredient, part of the long-chain alkyl hydroxyethyl imidazoline group, is classified as corrosive and necessitates hazard classification. Related compounds have demonstrated severe effects, including necrotic tissue damage at 5% concentration in a rabbit study and corrosive skin responses after 1-hour and 4-hour exposures. While acute dermal toxicity is generally low and sensitization at cosmetic levels is not anticipated, there is a likely risk of respiratory irritation. In its solid form, it can cause irritation to the skin, eyes, and respiratory system. The Cosmetic Ingredient Review (CIR) has not yet assessed this ingredient.
