What Is Lauryl Trimethyl Ammonium Chloride?

LTAC starts with lauryl alcohol, a fatty alcohol most commonly sourced from coconut oil. It’s combined with trimethylamine, then quaternized (chemistry talk for a process that gives it that helpful positive charge).

The end result is an eco-friendly surfactant that softens fabrics and neutralizes their charge, which helps reduce the amount of dirt, grime, and other organic residues that get redeposited on clothes.

How Lauryl Trimethyl Ammonium Chloride Works

In the laundry world, opposites attract—literally. Most fabrics and dirt particles carry a negative electrical charge, while Lauryl Trimethyl Ammonium Chloride carries a positive one. When you add it to your wash or spray it on fabrics, those opposite charges bond together.

The result?

  • Reduced static
  • Fibers that lie flatter and feel smoother
  • Clothes that come out soft, refreshed, and ready to wear.


It’s a simple bit of chemistry that makes a noticeable difference in how your laundry looks, feels, and acts.
