Dodecylamine polyoxyethylene ether AC-1210 is a non-ionic surfactant that is readily soluble in water. It is typically used by direct addition or after pre-dilution before being added to the formulation system. The specific usage should be flexibly adjusted according to the application scenario.
Detailed Explanation
Dodecylamine polyoxyethylene ether AC-1210 (HLB value approximately 13.5, cloud point 60~80°C) is a colorless to slightly yellow liquid at room temperature, with good water solubility and chemical stability. In practice, it can be directly added to the formulation system and quickly dispersed and dissolved under appropriate stirring. For formulations with higher requirements, it is recommended to pre-mix this product with part of water or solvent into a homogeneous solution before adding it to the main reactor, which helps to more precisely control the addition amount and achieve uniform distribution. Due to its certain hygroscopicity, the container should be sealed immediately after use.
Its weak cationic nature and excellent compatibility allow it to be used in combination with anionic, non-ionic, cationic, and amphoteric surfactants. When blending, it is recommended to dissolve AC-1210 and anionic auxiliaries separately and then mix them in sequence to avoid possible local gelation. It maintains good surface activity in both acidic and alkaline media, but before long-term use under extreme pH conditions, it is recommended to first perform small-scale tests to verify stability.
Application Recommendations
Due to the wide range of applications of this product, the usage methods and recommended dosages (based on total formulation weight) vary significantly across different industries. The following values are general recommendations based on industry experience; the exact precise ratio should be determined through experiments:
- Textile dyeing leveling agent: Recommended dosage 0.5~2 g/L (dye bath). Add at the initial stage of dyeing, using its fiber-affinic weak cationic properties to occupy dye sites and slow down the dye uptake rate, thereby achieving uniform dyeing. Can be used in combination with non-ionic and anionic leveling agents.
- Metalworking fluids and acidic cleaners: Recommended dosage 2~8 %. As an emulsifier and corrosion inhibitor, it can be added to the oil phase before mixing the oil and water phases, stirred evenly, and then emulsified with the water phase to obtain a more stable emulsion and anti-rust effect.
- Personal care products (shampoo, body wash): Recommended dosage 0.5~3 %. Usually added when the system is cooled to 40~50°C, then stirred evenly. It effectively enhances the thickening performance and conditioning properties of the formulation, improving skin feel and hair feel during use.
- Pesticide formulations (emulsifiable concentrate, emulsion in water): Recommended dosage 5~15 % (based on oil phase). Mix this product uniformly with pesticide technical material and solvent, and use it as a key component of the composite emulsifier. Upon dilution with water, the mixture can automatically form a stable emulsion.
- Industrial heavy-duty oil stain cleaners: Recommended dosage 3~10 %. Directly add to alkaline or acidic cleaning base solutions; with its excellent penetration and emulsifying ability, it can quickly strip heavy oil stains and carbon deposits from metal surfaces.

Precautions
- Pre-treatment: Long-term storage at low temperature may cause increased viscosity or turbidity; this is a physical change and not deterioration. Before use, warm the product to 20~40°C and stir evenly to restore it.
- Operation safety: This product is classified as skin/eye irritant Category 2. When handling, must wear nitrile rubber gloves and chemical safety goggles. In case of eye contact, immediately rinse with plenty of water for at least 15 minutes and seek medical attention.
- Compatibility limitations: Although it has broad compatibility, side reactions may occur when directly mixed with high-concentration strong oxidizing agents; such operations should be avoided.
