What is it?

Behentrimonium Chloride (BTAC-2) — a long-chain quaternary ammonium salt (C22, behenic acid). Its cationic nature allows it to adsorb onto the negatively charged surface of hair and skin. The longer carbon chain (C22 vs. C16 in cetrimonium) provides a gentler action and better tolerance. Used in concentrations of 0.5–3% in conditioners, masks, and styling products.

A basic component of conditioners, balms, and hair masks. A softer and skin-safe alternative to cetrimonium chloride. Suitable for sensitive scalp and fine hair.

Key Benefits

✦

Conditioning and easing combing

Adsorbs onto the hair surface, smoothing the cuticles and reducing friction between strands. Significantly eases combing of wet hair — reducing combing force by 40–60% compared to unconditioned hair. Leaves hair soft without weighing it down.

◈

Antistatic effect

The cationic charge neutralizes the negative static charge on the hair surface, which occurs from friction and dryness. The effect is noticeable immediately after application — especially relevant for fine and porous hair in dry weather.

✧

Softness and reduced irritability

The longer C22 chain forms a denser layer on the surface — less washes out and penetrates less into cells. Clinically shown to have better tolerance on the scalp compared to cetrimonium chloride at the same concentrations. An optimal choice for "sulfate-free and silicone-free" products.

Behentrimonium vs Cetrimonium

Cetrimonium chloride (C16) — more common and cheaper, but a stronger irritant. Behentrimonium chloride (C22) — more expensive, but gentler, with a better safety profile. Behentrimonium is more commonly found in premium conditioners. Both are effective conditioners, but behentrimonium is better tolerated by sensitive skin.
