Cocodimethylamine Oxide (CAS NO : 61788-90-7)

No. Biggest functional difference between them: Cocodimethylamine is not amphoteric. Being base. In water, it stays basic or can become cationic (positively charged) if neutralised with an acid. It does not carry a negative charge. On the other hand Cocodimethylamine Oxide is amphoteric (or "pseudo-amphoteric"). Its charge changes depending on the pH of the liquid it's in: In acidic environments: It becomes cationic (positive charge), providing conditioning properties. In neutral/alkaline environments: It behaves like a non-ionic surfactant, providing stable foam and cleaning power.
