The main component of Dodecylamine Polyoxyethylene Ether AC-1210 is Polyoxyethylene (10) Dodecyl Ether, a nonionic surfactant synthesized from dodecyl alcohol (lauryl alcohol) as the hydrophobic group and 10 moles of ethylene oxide via addition polymerization.

Detailed Explanation

From a chemical perspective, AC-1210 is a high-purity fatty alcohol polyoxyethylene ether. According to the product database of Guoli Chemical, its molecular formula is C32H66O11, with an average molecular weight of approximately 626 g/mol. Although the product name includes "dodecylamine" due to its synthesis route, the final product structure does not retain free amine groups (the database clearly indicates that both "amine value" and "tertiary amine content" are "none"). Instead, the polyoxyethylene ether chain and tertiary amine group impart nonionic properties with weak cationic characteristics.

Its commercial aliases directly reflect the main component: it is often called Lauryl Alcohol Polyoxyethylene Ether (10) [AEO-10], POE(10) Lauryl Ether, or PEG-10 Lauryl Ether. The "10" represents the average number of moles of ethylene oxide added, which is a key naming factor. The product has an active content of over 99% and appears as a colorless to slightly yellow liquid, readily soluble in water and various organic solvents.

Application Recommendations

Based on the structural characteristics of its main component (long-chain alkyl and polyoxyethylene ether chains), AC-1210 exhibits excellent emulsifying, wetting, and dispersing capabilities. It is widely used in textile dyeing and printing as a leveling agent for acid dyes, in industrial cleaning as an emulsifier for heavy oil stains, and in pesticide formulations as a wetting and penetrating agent. In personal care products, it serves as a mild conditioner and thickener.

Precautions

Although this product is composed of high-purity alcohol ethers without free amines, according to the safety database, it may still cause skin and serious eye irritation. Gloves and goggles should be worn during operation, and it should be stored in a cool, dry place (recommended temperature 5–40℃). It is chronically toxic to aquatic organisms, and waste should not be discharged directly into water bodies.
