Product Description
What Is Lauryl Dimethylamine Oxide?
A common non-ionic surfactant in industrial, domestic, and personal care applications is Lauryl Dimethylamine Oxide (OA-12). It is derived from laurylamine (a fatty amine) and dimethylamine oxide. Excellent foaming, mildness, and conditioning properties are well-known attributes of the chemical.
Preparation Method:
Lauryl Dimethylamine Oxide is typically synthesized through the reaction of laurylamine (C12H27NH2) with dimethylamine oxide (N,N-dimethylhydroxylamine). The reaction occurs under controlled conditions, involving the addition of an oxidizing agent to introduce the oxygen atom into the nitrogen structure, creating the final oxide compound. The reaction is usually carried out in an aqueous solution, followed by neutralization and purification steps to obtain the desired product.

User Asked Question:
Q: How does Lauryl Dimethylamine Oxide compare to Cocamidopropyl Betaine (CAPB)?
A: There are two mild surfactants included in personal care products: Lauryl Dimethylamine Oxide and Cocamidopropyl Betaine. Lauryl Dimethylamine Oxide offers better foaming and conditioning properties, leaving hair and skin smoother. In contrast, Cocamidopropyl Betaine is primarily used for its foaming abilities and to reduce irritation from harsher surfactants. Both provide mild cleansing, but Lauryl Dimethylamine Oxide is more conditioning and suitable for sensitive skin.
