BEHENAMIDOPROPYL ETHYLDIMONIUM ETHOSULFATE.

Valuable CAS 68797-65-9 / ANTISTATIC, HAIR CONDITIONING

A specialized quaternary ammonium conditioning agent that imparts a silky, lubricious feel to the skin surface. It functions as both a sophisticated emollient and a film-former, bridging the gap between sensory elegance and functional barrier support.

Skin conditioning Antistatic Emollient Film former

Science

This molecule carries a positive (cationic) charge that allows it to bond substantively with the skin's naturally negative surface. It creates a micro-thin, breathable barrier that neutralizes static, smooths texture, and physically inhibits transepidermal water loss (TEWL) while facilitating the deposition of lipophilic active ingredients.

Key findings

  1. 01 Clinical evaluations demonstrate a measurable increase in skin hydration and a significant reduction in TEWL within the 0.5% to 5.0% range.
  2. 02 Ocular and dermal safety assessments confirm the ingredient is non-irritating and can actively mitigate the irritation potential of anionic surfactants in the same formula.
