1. Basic Attributes

• Product Name: HYDRAPOL RP90, categorized as a linear ethoxylated fatty alcohol nonionic surfactant and an environmentally friendly alternative to traditional nonylphenol ethoxylate (NP-10).
• Core Component: Polymer of C₁₀-C₁₃ linear fatty alcohol and ethylene oxide, with an average ethoxylation degree of 9-10 and a theoretical molecular weight of approximately 580-620.
• Key Certifications: HLB value of 13 (Hydrophilic-Lipophilic Balance). Complies with EU REACH Regulation, US EPA environmental standards, and China’s GB/T 26396-2011 Test Method for Biodegradability of Surfactants, with no residues of NP (nonylphenol) or APE (alkylphenol ethoxylate).

2. Core Physicochemical Properties

3. Functions and Typical Application Scenarios

• Core Functions:

  1. Efficient Wetting and Penetration: Rapidly reduces the surface tension of liquids (lowering water’s surface tension from 72 mN/m to 32-35 mN/m), promoting liquid penetration into gaps on solid surfaces and improving cleaning or treatment efficiency.
  2. Stable Emulsification and Dispersion: Uniformly disperses oil phases (e.g., mineral oil, grease) or solid particles (e.g., pigments, pesticide technical materials) in water phases to form stable emulsions or suspensions, preventing stratification.
  3. Mild Cleaning Ability: Combines surface activity with low irritation, capable of removing contaminants such as oil stains and dust, while causing minimal corrosion to metals, fabrics, and skin.

• Typical Application Fields:

  • Industrial Cleaning: Used in formulations of metal surface degreasers, electronic component cleaners, and automotive parts cleaners. With an addition amount of 2%-5%, it can increase oil-stripping speed by over 30%.
  • Agrochemical Industry: Serves as an emulsifying dispersant for pesticide suspension concentrates (SC) and emulsifiable concentrates (EW), compatible with high-electrolyte formulations (e.g., foliar fertilizers containing potassium sulfate or ammonium chloride). An addition amount of 1%-3% ensures thermal storage stability of the formulation.
  • Household Daily Chemicals: Used in laundry detergents, dishwashing liquids, and kitchen heavy oil cleaners to replace NP-10 for environmental compliance. With an addition amount of 3%-8%, it enhances decontamination while reducing skin irritation.
  • Emulsion Polymerization: Acts as an emulsifier for styrene-acrylic emulsions and vinyl acetate emulsions, controlling latex particle size (adjustable to 0.1-0.3 μm) and improving the film-forming property and adhesion of the emulsion.

4. Usage Specifications and Precautions

• Recommended Addition Amount: Adjust according to application scenarios—2%-5% for industrial cleaning, 1%-3% for agriculture, and 3%-8% for daily chemicals. Small-scale tests are recommended to confirm the optimal ratio.
• Compatibility: Can be compounded with anionic (e.g., sodium dodecylbenzenesulfonate), cationic (e.g., cetyltrimethylammonium chloride), and other nonionic surfactants without compatibility issues. Avoid long-term contact with strongly acidic (pH＜3) or strongly alkaline (pH＞12) substances to prevent component degradation.
• Storage Requirements: Seal and store in a cool, ventilated place (5-35℃), avoiding direct sunlight and high temperatures. Use as soon as possible after opening to prevent moisture absorption or oxidation; unopened shelf life is 24 months.
• Safety: Acute oral toxicity LD50 (rat) ＞5000 mg/kg, classified as low-toxicity. For industrial-grade products, gloves are recommended during operation to avoid prolonged direct skin contact.
