Ditallow dimethyl ammonium chloride

Ditallow dimethyl ammonium chloride (CAS 68783-78-8), also marketed as Armosoft M, is a dialkyl quaternary ammonium compound derived from tallow fatty acids.

Where is Ditallow dimethyl ammonium chloride used?

• Textile processing: fabric softener and antistatic agent that reduces fiber friction
• Rinse-cycle and industrial finishing formulations: improves handle
• Personal care: hair conditioners and rinse-off treatments, adsorbing onto negatively charged hair surfaces for detangling and softness
• Water treatment: flocculant aid and biocidal additive that destabilizes suspended solids
• Industrial effluent systems: controls microbial growth
• Leather and paper finishing: surface modifier for flexibility, water repellency and substrate uniformity
• It functions as a cationic surfactant, delivering softening and antistatic effects.

Good to know: Specifications vary by active content and tallow source, whether hydrogenated or non-hydrogenated; this affects color and odor profile, relevant during end-use selection.

Commercial specifications

• Active matter concentrations of 50–75%
• Specifications vary by active content and tallow source
