INCI name Behentrimonium Chloride
CAS number 17301-53-0
Behentrimonium chloride is a quaternary ammonium salt derived from canola (Brassica rapa olifera). This waxy, water-insoluble solid has a fishy odor and requires no stabilizing agent. With 22 carbon atoms, it offers superior lubricity and conditioning compared to cetrimonium chloride. It is commonly used in hair and skincare formulations for its effective conditioning properties.
Purpose
Behentrimonium chloride acts as an antistatic agent, reducing frizz and flyaways in hair. Its emulsifying properties help blend oil and water-based ingredients in formulations. As a hair conditioning agent, it softens, smooths, and enhances manageability. Additionally, it has mild preservative effects, contributing to product stability and longevity.
Origin
Behentrimonium chloride is sourced from canola oil, extracted from canola seeds through heating and mechanical pressing using screw presses or expellers. To maximize yield, solvents are applied to the leftover presscake, followed by a steam and heat process to remove the solvent. The final compound is produced by quaternizing behenyl dimethylamine with methyl chloride in a 30% dipropylene glycol solution.

Deep Conditioning & Long-Lasting Smoothness
Behentrimonium chloride has a strong affinity for hair fibers, forming a conditioning layer that lasts even after rinsing. This makes it highly effective in reducing frizz and improving hair texture over time.
Exceptional Detangling & Slip
Unlike many other conditioning agents, it provides superior slip, making hair easier to comb through, especially for curly, coily, or damaged hair. It helps prevent breakage caused by tugging and knots.
Powerful Antistatic & Anti-Frizz Properties
As a cationic surfactant, it neutralizes negative charges on the hair, preventing static buildup and flyaways, resulting in smoother and more manageable hair.
Non-Greasy & Lightweight Feel
Unlike heavier conditioning agents, Behentrimonium Chloride conditions without leaving hair greasy or weighed down, making it suitable for both fine and thick hair types.
Gentle on Scalp & Hair
Compared to harsher quaternary ammonium compounds, Behentrimonium Chloride is mild and non-irritating, making it a preferred choice for sensitive scalps and clean beauty formulations.
Versatile & Stable in Formulations
It works well in a wide range of haircare products, including shampoos, conditioners, hair masks, and leave-in treatments. It also stabilizes emulsions in skincare products like lotions and creams.
Naturally Derived & Biodegradable
Sourced from rapeseed oil, it is an eco-friendly alternative to synthetic conditioning agents, breaking down more easily in the environment while still delivering high-performance results.
