Posted on August 25, 2026 By admin No Comments on OA-12 – Dodecyl Dimethyl Amine Oxide (CAS 1643-20-5)

Shandong Kairui Chemistry Co., Ltd. proudly presents OA-12, a high-performance dodecyl dimethyl amine oxide that stands as a benchmark in the surfactant industry. With CAS No. 1643-20-5 and a molecular formula of C₁₄H₃₁NO (molecular weight 229.4), Dodecyl Dimethyl Amine Oxide offers exceptional versatility across an extensive range of applications.

OA-12, also known as lauryl dimethyl amine oxide or lauramine oxide, is a premium amphoteric/nonionic surfactant that delivers outstanding performance in cleaning and personal care formulations. Its primary function as a foam booster and stabilizer makes it essential for products requiring superior lather characteristics. Additionally, OA-12 serves as an effective thickener that improves the compatibility of thickening agents and enhances overall product stability.

The compound’s versatility extends to its role as a conditioner, providing softening and antistatic properties that enhance the performance of hair and skin care products. It also functions as an emulsifier, wetting agent, and dyeing auxiliary, making it valuable in textile processing applications. Furthermore, OA-12 exhibits mild biocidal properties and can serve as a sterilizing agent in appropriate formulations.

The primary applications of OA-12 include dishwashing detergents, where it enhances foam and cleaning performance. In industrial liquid bleach formulations, it improves stability and efficacy. Shampoos, liquid detergents, and foam baths benefit from its foam-boosting, conditioning, and thickening properties. As a raw material for the synthesis of amphoteric surfactants, OA-12 plays a crucial role in the production of advanced surface-active agents.

Available as a 30% active aqueous solution with a density of 0.996 g/mL, OA-12 is easy to handle and formulate. Shandong Kairui Chemistry Co., Ltd. delivers consistent, high-quality OA-12 to meet your surfactant needs.
