Dodecylamine polyoxyethylene ether AC-1205 (CAS No.: 26635-75-6) is a non-ionic surfactant prepared by ethoxylation with dodecylamine as the starting agent. Under conventional conditions, it exhibits non-ionic properties, but in acidic media, the amine group undergoes protonation, showing cationic characteristics. Before use, be sure to consult the Safety Data Sheet (SDS), and operators should receive professional training to be familiar with the hazardous properties and emergency measures of this product.
This product is classified under GHS as Skin Irritation Category 2 (H315) and Serious Eye Irritation Category 2 (H319). During operation, chemical safety goggles, protective gloves made of nitrile rubber or similar materials, and appropriate protective clothing must be worn. The operating area should be well-ventilated, and local exhaust ventilation should be installed if necessary. Avoid inhaling vapors, aerosols, or dust. If ventilation is insufficient, wear respiratory protection for particulates and organic vapors. Eating, drinking, or smoking is prohibited in the operating area.
This product is harmful to aquatic life with long-lasting effects (H412). The typical 96h LC50 for fish ranges from 1 to 10 mg/L, and it is not readily biodegradable in aquatic environments. Therefore, it is strictly prohibited to discharge this product or waste liquids containing it directly into sewers, surface waters, or soil. Spills should be collected using inert absorbent materials, and waste must be managed as hazardous waste and disposed of by qualified professional agencies.

Utilization in Acidic Systems: If the cationic characteristics need to be leveraged (e.g., for enhanced sterilization, fiber adsorption, corrosion inhibition, etc.), the system pH should be adjusted to an acidic range to protonate the amine groups, thereby achieving excellent adsorption and affinity. This property is particularly crucial in applications such as pesticide tank-mix adjuvants and oilfield acidizing corrosion inhibitors.
Emulsification/Dispersion Process: When preparing emulsions or dispersions, it is recommended to pre-dissolve AC-1205 in the oil phase or water phase (depending on the specific formulation) and then gradually mix in the other phase to fully utilize its ability to reduce interfacial tension. When used in formulations with high electrolyte content or extreme temperature conditions, its chemical tolerance advantage is prominent.
Dosage Reference: As an emulsifier, the typical addition amount is 2% to 8% of the system; as a leveling agent and antistatic agent, 0.5% to 3% is recommended. Specific dosages should be determined through experiments based on the actual formulation system and process conditions.
