When using Octadecylamine polyoxyethylene ether AC-1815, it is essential to focus on personal protection to avoid irritation to the skin, eyes, and respiratory tract, ensure adequate ventilation in the operating area, and strictly follow recommended storage conditions to maintain product performance and safety.
Detailed Explanation
Octadecylamine polyoxyethylene ether AC-1815 is a nonionic surfactant with unique ionic characteristic conversion capabilities, and special attention must be paid to its chemical properties during application. It exhibits nonionic characteristics under neutral or alkaline conditions, while converting to a cationic form in acidic systems. This conversion ability endows it with excellent adsorption and conditioning properties, but the pH environment of the formulation must be considered during compounding to avoid precipitation or failure when mixed with incompatible auxiliaries. The product has good chemical stability and is stable at room temperature, but direct contact with strong acids, strong bases, and strong oxidizers should be avoided.
Operational safety is the primary concern. According to GHS classification, this substance can cause irritation to the skin, eyes, and respiratory tract. Therefore, all personnel involved in weighing, feeding, or handling heated molten products must wear chemically resistant protective gloves, safety goggles or full-face shields, and appropriate protective clothing. Operations should be conducted in areas equipped with local exhaust or general ventilation to prevent accumulation of dust or vapor. After handling, thoroughly wash any exposed skin areas such as face and hands.
Product storage directly affects its service life and effectiveness. Octadecylamine polyoxyethylene ether AC-1815 is slightly hygroscopic, appearing as a white to light yellow waxy solid or paste, with a melting point of approximately 30-40°C. It should be stored sealed in a cool, dry, well-ventilated warehouse, away from fire and heat sources. The storage temperature is recommended to be below 40°C, avoiding direct sunlight and high humidity environments to prevent moisture absorption, caking, or melting and clumping due to high temperatures. Under unopened and properly stored conditions, the shelf life is up to 12 months.

Application Suggestions
- Textile Dyeing and Printing: When used as a high-temperature leveling agent or antistatic agent, it is recommended to add it at the initial stage of dyeing, utilizing its excellent migration properties to achieve uniform coloring. In synthetic fiber spinning oils, it serves as a smoothing and bundling component, effectively reducing the breakage rate.
- Metalworking Fluids: As an emulsifier and corrosion inhibitor in emulsifiable oils or semi-synthetic cutting fluids, its cationic adsorption film provides reliable inter-process rust protection for ferrous and non-ferrous metals. The recommended dosage should be determined through compatibility tests.
- Pesticide Formulations: When formulating emulsion concentrates (EW) or microemulsions (ME), it exhibits good emulsifiability for various organophosphorus and pyrethroid active ingredients, ensuring self-emulsification of the diluted liquid and enhancing wetting and spreading effects during field spraying.
- Household and Personal Care Products: As a co-emulsifier and viscosity modifier in shampoos and body washes, it provides antistatic and soft feel properties, improving wet and dry combability. It is typically used in combination with other surfactants.
Precautions
- Emergency Measures: In case of skin contact, immediately wash with plenty of soap and water and remove contaminated clothing; for eye contact, rinse the opened conjunctival sac gently with clean water for at least several minutes. Remove contact lenses if present and continue rinsing. If irritation persists, seek medical attention. If inhaled, move to fresh air. If ingested, do not induce vomiting; seek medical attention immediately and show this safety data sheet.
- Waste Disposal: Do not discharge the contents or contaminated containers into drains or the environment. Dispose of all waste in accordance with local, regional, and national regulations.
- Usage Restrictions: Although current data do not indicate carcinogenicity, mutagenicity, or reproductive toxicity, prolonged or repeated direct contact may cause skin defatting and dryness. Avoid continuous exposure.
