This is a 70% solution of cetyltrimonium chloride in alcohol. It is a white to off-white paste that dries very quickly and mixes well with other ingredients. Because it is alcohol-based, it is suitable for systems where the addition of water is not recommended, such as some sprays or quick-drying formulations. Its pH is stable between 6 and 8, making it suitable for most general applications.
What It Does
Cetrimide adheres to typically negatively charged surfaces, such as hair and fabric fibers. Upon application, it forms a smooth film that reduces static and makes the surface feel softer. In alcohol-based systems, it spreads and dries quickly, so you don't have to wait too long to notice the conditioning effects. It's often used as a cationic conditioning agent in both personal care and fabric care applications because it helps make things feel smoother and less likely to stick together.
Where It Works Best
This ingredient is often found in lightweight hair care products—think leave-in conditioners and detangling sprays—to help hair manage easily and leave it feeling soft and smooth. It's also useful in fabric softeners and anti-static sprays, especially for synthetic fibers. Its fast evaporation makes it a popular choice for hygiene products or surface care products that require quick drying and minimal residue.
How to Use It in a Formula
Because of its high concentration, you don't need to use a large amount to see results. It works well with a wide range of ingredients, especially nonionic or amphoteric ones. Its alcohol base makes it easy to incorporate into water-free systems, and its fast drying time is a major advantage in formulations where speed is key—from personal care sprays to industrial cleaners.
