Where is Quaternium-18 used?

• Hair care and rinse-off conditioners: deposits onto negatively charged hair fibers to reduce static, improve combability and deliver a smooth feel
• Fabric softeners: imparts softness and antistatic performance to textile substrates
• Textile and leather processing: fiber lubricant and surface modifier that improves handle and reduces friction
• Industrial and institutional cleaning: biocidal or conditioning additive where cationic surface activity is required
• During rinse cycles it provides essential conditioning properties.

Good to know: Cosmetic-grade material meets high purity requirements, suitable for rinse-off and leave-on personal care formulations.

Commercial specifications

• 75% active concentrate in isopropanol or water-based carrier systems
• Bulk supply in drums and intermediate bulk containers (IBCs)
