2. Physical and Chemical Properties

3. Key Performance Characteristics

Versatile Surface Activity
Combines hydrophobic lauryl chains (for oil solubility) and hydrophilic polyoxyethylene chains (for water solubility), enabling multi-functional performance:

2. • Detergency: Emulsifies oils and dirt, lifting contaminants from surfaces (e.g., fabric fibers, metal parts).
   • Emulsification: Stabilizes oil-in-water (O/W) or water-in-oil (W/O) emulsions (e.g., textile lubricants, cosmetic creams) with low dosage (0.5%–2%).
   • Wetting/Penetration: Reduces surface tension to accelerate liquid penetration into porous materials (e.g., plant seeds, textile yarns).
3.  

Mildness and Compatibility
As a nonionic surfactant, it has lower skin/eye irritation than anionic surfactants (e.g., SLES, LAS). Skin irritation tests (OECD 404) rate it "mild," and it is compatible with anionic, cationic, and amphoteric surfactants—no precipitation or efficacy loss when blended (e.g., with Polyquaternium-10 in hair care).

Temperature Adaptability
Grades with different EO units (n) offer tailored cloud points:

6. • Low EO grades (n=3–5): Cloud point <10°C, suitable for cold-water applications (e.g., cold laundry detergents).
   • Medium EO grades (n=9–10): Cloud point 90–96°C, ideal for high-temperature processes (e.g., textile dyeing at 80–90°C).
   • High EO grades (n=15–20): Soluble in cold water, used in cosmetic emulsions (e.g., facial creams).
7.  

Environmental Friendliness
Meets global biodegradability standards: 28-day biodegradation rate ≥90% (OECD 301B), with no persistent organic pollutant (POP) residues. It is compliant with EU ECOLABEL and US EPA Safer Choice criteria, reducing environmental impact.

4. Application Fields

1. Textile Industry (Core Scenario)

• Leveling Agent: Added to dyeing baths (0.2–1 g/L) for cotton, polyester, and blended fabrics—prevents uneven dye absorption, ensuring bright, consistent colors (reduces dye defects by 40%).
• Diffusing Agent: Enhances dye penetration into thick fabrics (e.g., denim, canvas), improving color fastness (washing fastness ≥Grade 4).
• Stripping Agent: Removes excess dye from fabric surfaces (e.g., in corrective dyeing) without damaging fibers.
• Lubricant Emulsifier: Emulsifies mineral oil-based lubricants (1–3% dosage) for textile weaving, reducing yarn breakage by 30%.

2. Industrial Cleaning

• Metal Degreaser: Formulated into industrial detergents (5–10% dosage) for aluminum, steel, and copper parts—removes cutting oil, grease, and rust inhibitors efficiently (degreasing rate ≥95% in 10 minutes at 60°C).
• Glass Fiber Cleaner: Cleans glass fiber surfaces (0.5–2% dosage) to remove sizing agents, improving resin adhesion in composite manufacturing.
• Hard Surface Cleaner: Used in floor cleaners, equipment detergents (3–5% dosage)—effective on oil stains and compatible with disinfectants (e.g., quaternary ammonium salts).

3. Daily Chemicals (日化)

• Detergents: Added to laundry detergents (2–5% dosage) and dishwashing liquids—enhances oil emulsification and reduces surfactant irritation (suitable for sensitive-skin detergents).
• Cosmetics: Low-EO grades (n=3–5) as solubilizers in perfumes, high-EO grades (n=15–20) as emulsifiers in creams/lotions (1–3% dosage)—improves product texture and stability.
• Personal Care: Used in mild shampoos and body washes (0.5–2% dosage)—reduces scalp irritation and enhances foam stability.

4. Agriculture & Other Fields

• Agricultural Penetrant: Added to pesticide formulations (0.1–0.5% dosage)—improves pesticide penetration into plant leaves and insect cuticles, boosting efficacy by 25%.
• Seed Treatment: Used in seed-soaking solutions (0.2–0.3% dosage)—enhances water absorption by seeds, increasing germination rate by 15–20%.
• Pharmaceuticals: As a solubilizer in oral liquids and topical ointments (USP-grade)—improves drug solubility and bioavailability.

5. Safety & Usage Guidelines

• Hazards & Precautions:
  • Skin/Eye Contact: Solid/liquid forms are mild, but prolonged contact with high-purity (≥99%) product may cause dryness. Wear gloves during handling; rinse with water for 15 minutes if contact occurs.
  • Thermal Stability: Avoid heating above 120°C to prevent decomposition (releases toxic ethylene oxide).
  • Incompatibility: Do not mix with strong oxidizers (e.g., concentrated nitric acid) or strong acids (pH <2) to avoid degradation.
• Recommended Dosage:
  • Textiles: 0.2–1 g/L (leveling agent); 1–3% (lubricant emulsifier).
  • Industrial Cleaning: 5–10% (metal degreaser); 3–5% (hard surface cleaner).
  • Daily Chemicals: 2–5% (detergents); 1–3% (cosmetic emulsifiers).

6. Packaging & Storage

1. Packaging Forms

• Industrial Grade (n=9–10, solid/flake): 200 kg galvanized iron drums, 50 kg HDPE plastic drums, or 25 kg woven plastic bags (with PE liners)—moisture-proof and sealed to prevent caking.
• 日化 Grade (n=15–20, paste/liquid): 25 kg HDPE plastic buckets or 1000 L IBC totes—food-grade compliant for cosmetic/detergent use.
• Sample Sizes: 100 g aluminum foil bags (solid) or 1 L HDPE bottles (liquid)—for R&D trials.

2. Storage Conditions

• Store in a cool, dry, well-ventilated warehouse (temperature 5–35°C, relative humidity <75%); avoid direct sunlight and moisture (prevents caking).
• If caking occurs (due to moisture), gently crush and heat to 40–50°C to restore uniformity—do not use open flame heating.
• Shelf Life: Unopened containers—24 months (industrial grade); 18 months (日化 grade). Use opened packages within 3 months and reseal promptly.
