The molecular structure of Dodecylamine Polyoxyethylene Ether AC-1205 (CAS No.: 26635-75-6) determines its unique "dual ionic properties": under conventional conditions, it behaves as a nonionic type, endowing the product with excellent formulation compatibility, allowing harmonious combination with other surfactants and auxiliaries; when the system switches to an acidic environment, the amine group in the molecule undergoes protonation, exhibiting cationic characteristics, thus providing excellent adsorption and strong affinity for negatively charged surfaces. This switchable ionic property is the core highlight distinguishing this product from ordinary nonionic surfactants.
In terms of performance, AC-1205 demonstrates five significant advantages: ① Efficient emulsification ability, quickly reducing oil/water interfacial tension to form a stable and fine emulsion system, especially suitable for formulations with high electrolyte content or extreme temperature conditions; ② Lasting dispersion stability, providing excellent dispersion and suspension effects on pigments, solid particles, and active substances, effectively preventing sedimentation, flocculation, and agglomeration; ③ Excellent wetting and spreading property, significantly reducing the contact angle of working fluids on substrates such as fabrics, metals, and plastics, improving penetration rate and uniformity; ④ Superior chemical resistance, maintaining stable surface activity and dissolution state in acid, alkali, and hard water systems; ⑤ Antistatic and conditioning function, the molecular structure imparts good antistatic effects on fibers and surfaces, while providing a soft and smooth touch modification.
In practical applications, AC-1205 covers a wide range of fields including agrochemical formulations (pesticide emulsifiers, dispersible oil suspension adjuvants, tank mix synergists), textiles and leather (high-temperature leveling agents, fiber antistatic agents, post-dyeing soaping agents), daily chemicals (hair conditioners and shampoo conditioners, fabric softeners, hard surface cleaners), industrial and metal processing (metal cutting and grinding fluid additives, pigment and coating dispersants), as well as petroleum and energy sectors (crude oil demulsifiers and desalting agents, oilfield acidizing corrosion inhibitor synergists), with extremely broad application areas.
