Decyldimethylamine oxide

Decyldimethylamine oxide (CAS 2605-79-0), also known as capric dimethyl amine oxide, is an amphoteric surfactant that shifts between cationic and nonionic behavior depending on pH.

Where is Decyldimethylamine oxide used?

• Personal care: boosts foam volume and stabilizes lather in shampoos
• Body washes and facial cleansers: improves the feel of the rinse
• Industrial and institutional cleaning: enhances detergency and supports emulsification
• Water treatment: dispersing action that breaks down organic deposits
• Textile and paper processing: softening and conditioning aid for surface modification during wet finishing
• It helps break down oils and greases at lower active concentrations.

Good to know: Personal care-grade versions meet the purity requirements expected for rinse-off and leave-on cosmetic applications.

Commercial specifications

• Aqueous solution, typically 30% active content
• Drum and IBC packaging for commercial quantities and bulk logistics
