Setramidopropyl Diethylamine

Setramidopropyl Diethylamine is a cationic conditioning agent widely used in hair care formulations, especially conditioners, masks, and shampoos.
It provides excellent detangling, softness, anti-frizz, and conditioning performance, particularly on damaged, dry, and chemically treated hair.

In formulations, it is typically neutralized with an acid (e.g., citric or lactic acid) to form an effective conditioning salt, delivering smoothness and improved combability.
