Dodecyl amine polyoxyethylene ether AC-1215 is a non-ionic surfactant polymerized from fatty amine (dodecylamine/laurylamine) and 15 moles of ethylene oxide, possessing both non-ionic and cationic characteristics, widely used in textile printing and dyeing, pesticide formulations, industrial cleaning, daily chemical care, and metalworking fluids.

Detailed Description

Dodecyl amine polyoxyethylene ether AC-1215 (CAS No.: 26635-75-6), also known as lauryl amine polyoxyethylene ether (15), PEG-15 lauryl amine, ethoxylated dodecylamine (15EO), etc., is a classic non-ionic surfactant produced by Guoli Chemical. Its molecular structure contains both amine functional groups and polyoxyethylene ether chains, endowing the product with excellent interfacial activity and multifunctional properties.

The product appears as a colorless to light yellow transparent liquid, with a pH of 8-10 (1% aqueous solution) and a density of about 0.95-1.05 g/cm³, exhibiting good water solubility. In acidic media, the protonation of amine groups in the molecule gives the product cationic surfactant behavior, extending its application range far beyond ordinary non-ionic surfactants. The product is resistant to hard water, acids, and alkalis, maintaining stable performance over a wide pH range.

AC-1215 integrates multiple functions such as emulsification, wetting, penetration, and dispersion: it can effectively reduce oil/water interfacial tension to form stable emulsions, promote liquid spreading on solid surfaces, and prevent flocculation and sedimentation of solid particles. At the same time, the product is easily biodegradable (BOD/COD ratio greater than 60% within 28 days) and does not persist in the environment, aligning with the development trend of modern green chemistry.

Application Suggestions

1. Textile Printing and Dyeing — Leveling Agent and Antistatic Agent: Provides excellent leveling effect in various fiber dyeing processes, reducing color difference and uneven dyeing; at the same time, imparts good antistatic properties to fabrics, lowering surface resistance and preventing tangling and adsorption caused by static accumulation during processing.

2. Pesticide Formulations — Emulsifying Dispersant: Suitable for formulations of emulsifiable concentrate (EC) and emulsion in water (EW), effectively reducing oil-water interfacial tension, improving emulsion stability and dispersion uniformity, ensuring active ingredients remain evenly distributed after dilution for a long time, significantly enhancing pesticide efficacy.

3. Industrial Cleaning — Solubilizer and Wetting Agent: Acts as an efficient solubilizer and wetting agent in industrial hard surface cleaning formulations, rapidly penetrating dirt layers and improving cleaning efficiency. Especially suitable for cleaning systems for hard surfaces such as metal, glass, and ceramics, compatible with both acidic and alkaline formulations.

4. Daily Chemical Care — Antistatic Conditioning Agent: Used in shampoos, conditioners, body washes, etc., providing excellent antistatic and conditioning functions, improving the feel of hair and skin, reducing frizz and static.

5. Metalworking Fluids — Emulsifying Antirust Agent: In formulations of cutting fluids, grinding fluids, etc., it combines emulsifying and antirust functions, forming a uniform protective film on metal surfaces to effectively inhibit rust, while ensuring system stability and lubricity.

6. Acidic Systems — Solubilizing Auxiliary: Used as a solubilizing aid in acidic cleaning, pickling, etc., utilizing the cationic characteristics of protonated amine groups to improve compatibility and solubility among components, preventing layering or precipitation.

Precautions

  • Safety Hazards: This product causes skin irritation (H315) and serious eye irritation (H319), and is harmful to aquatic life with long-lasting effects (H412). Wear protective gloves and goggles during operation.
  • First Aid Measures: In case of skin contact, rinse immediately with plenty of soap and water; for eye contact, rinse with clean water for at least 15 minutes, removing contact lenses if present and continuing rinsing; seek medical attention if irritation persists.
  • Storage Conditions: Store in a cool (5-35°C), dry, well-ventilated warehouse, keep container tightly closed, away from heat sources and strong oxidizers. The product may become pasty or solidify at low temperatures, which is normal.
  • Environmental Requirements: Do not discharge into drains or water bodies; disposal must comply with national and local regulations for hazardous waste management.
