Quaternium-45

Quaternium-45 (CAS 21034-17-3) is a quaternary ammonium compound used in personal care formulations for surface modification and stabilization. It functions as a conditioning and wetting agent, helping to improve the feel and performance consistency of cosmetic products.

In hair care formulations, this compound is used to modify surface charge on hair fibers, improving combability and reducing static. Skin care and leave-on products incorporate it to enhance ingredient adhesion and uniform distribution across the skin surface.

It also serves a stabilizing role in emulsion-based formulations, helping to maintain system integrity over shelf life. Conditioning rinses and treatment masks may include it at low concentrations to deliver targeted surface-active effects during application.

Quaternium-45 is typically supplied as a solid or powder. It is available in cosmetic-grade specification, with purity levels suited to personal care manufacturing requirements. Buyers should confirm grade documentation and batch consistency with suppliers.

Supply volumes for this specialty quaternary compound tend to be limited to small and mid-scale quantities. This makes it an ideal choice for niche cosmetic lines and specialized treatment products requiring high-performance surface modification properties.

The material is handled according to standard chemical safety protocols for quaternary ammonium salts. Manufacturers should ensure that the specific grade meets their internal quality control benchmarks for stability and compatibility within complex aqueous systems.
