Product Overview

Lauramine Oxide (also marketed as Lauryl Dimethyl Amine Oxide, LDAO or DDAO) — CAS 1643-20-5 — is a non-ionic/cationic-character amine oxide surfactant and gentle foam booster with excellent detergency, wetting, emulsification and antistatic properties. It improves foam volume and stability, enhances viscosity and thickener compatibility, and conditions hair and skin in personal care systems. Typical grades include 30% aqueous LDAO and technical concentrates.

This product is mainly used in dishwashing detergents and industrial liquid bleaches. It has the effect of increasing and stabilizing foam, and can improve the compatibility of thickeners and the overall stability of the product. It is also used in cosmetic and personal care product formulations, particularly in hair care products as a foaming agent, fragrance ingredient, viscosity builder, stabiliser, conditioner, emulsifier, wetting agent and antistatic agent.

Primary Applications & Benefits

Household & industrial detergents: dishwashing liquids, laundry, and industrial cleaners — increases and stabilizes foam, boosts detergency and wetting.
Personal care & haircare: foaming agent, viscosity builder, stabilizer, conditioner and antistatic agent in shampoos, bodywash and shower gels.
Formulation aid: improves compatibility with thickeners and polymers, reduces irritation vs some harsher surfactants.
Specialty cleaning & biocide formulations: used as a foam booster or co-surfactant in disinfectant and industrial bleach formulations.

Grades, Packaging & Supply

Grades: technical concentrates and standardized solutions (e.g., 30% LDAO).
Packaging: drums, IBCs and bulk tanks for large orders.
Supply & documentation: steady export supply; samples available on request.

Safety, Storage & Handling

Store in cool, dry, well-ventilated area away from strong oxidizers. Use PPE when handling concentrated materials; avoid contact with eyes and prolonged skin exposure. Lauramine Oxide is generally stable but combustible under extreme conditions.
