1. Basic Information

• English Name: Polyquaternium-47
• INCI Nomenclature: Polyquaternium-47 (official name for cosmetic use)
• CAS Number: 25136-75-8
• Chemical Composition: Terpolymer of N-Vinylpyrrolidone (PVP), 2-Dimethylaminoethyl Methacrylate (DMAEMA), and acrylic acid; quaternized with methyl chloride
• Molecular Formula: (C6​H9​NO⋅C8​H15​NO2​⋅C3​H4​O2​⋅CH3​Cl)n​ (repeating unit structure; n = degree of polymerization; typical monomer molar ratio: PVP:DMAEMA:acrylic acid = 40:40:20, customizable)
• Average Molecular Weight: Typical range of 300,000–1,000,000 Da (low MW: 300k–500k Da for skin care; high MW: 700k–1,000k Da for hair styling)
• Common Synonyms: PVP/DMAEMA/acrylic acid terpolymer quaternary salt; Quaternized PVP-DMAEMA-acrylic acid terpolymer

2. Physical and Chemical Properties

3. Key Performance Characteristics

1. Tri-Functional Synergy: Conditioning + Styling + pH Adaptability
   • The quaternized DMAEMA segment delivers intense conditioning by forming a protective layer on hair cuticles, reducing frizz and improving combability (consumer tests show 40% better wet detangling vs. single-component cationic polymers).
   • PVP provides flexible film-forming for long-lasting hair styling (6+ hours of curl retention in 80% humidity) without stiffness.
   • Acrylic acid enhances pH responsiveness, maintaining stability in acidic (e.g., exfoliating cleansers, pH 4.0) and neutral systems—unlike traditional cationic polymers that precipitate in low pH.
2. Gentle Biocompatibility for Sensitive Users
   Derived from FDA-approved PVP and low-irritation monomers, it has a "non-irritating" rating (OECD 404 skin irritation test) and no sensitization (OECD 406 test). It is safe for colored/chemically treated hair and baby care products (e.g., mild shampoos).
3. Enhanced Formulation Stability
   Acts as a stabilizer for emulsions and suspensions by reducing particle aggregation. In hair care formulations, it prevents surfactant-induced hair damage and extends product shelf life by 30% (vs. formulations without Polyquaternium-47).
4. Non-Cumulative Residue
   The adsorbed layer is easily removed with standard shampoos, leaving no sticky or waxy buildup—solving the "heavy hair" issue common with Polyquaternium-10 or other high-molecular-weight cationic polymers.

4. Application Fields

1. Personal Care (Core Scenario)

• Hair Care Products:
  • Shampoos & Conditioners: Adds conditioning benefits (reduces breakage, enhances shine) without weighing hair down; ideal for fine or limp hair formulations.
  • Hair Styling Products: Hair gels, mousses, and sprays—delivers flexible hold and humidity resistance; compatible with alcohol-based quick-drying sprays.
  • Leave-In Treatments: Repairs damaged hair by filling cuticle gaps; suitable for post-coloring or perming hair care.
• Skin Care Products:
  • Cleansers & Body Washes: Reduces surfactant-induced dryness by forming a mild protective film on skin; improves post-wash hydration (transepidermal water loss reduced by 15%).
  • Moisturizers & Serums: Enhances the adsorption of active ingredients (e.g., hyaluronic acid) and improves skin smoothness.
  • Baby Care: Mild shampoos and body washes—safe for delicate skin, no eye irritation.

2. Specialty Industrial Applications

• Textile Industry: Antistatic finish for synthetic fibers (e.g., polyester) — lowers surface resistance to <10⁸ Ω/sq, preventing static buildup.
• Water Treatment (Precision Use): Flocculant for ultra-pure water purification (e.g., semiconductor manufacturing) — adsorbs submicron particles without introducing impurities.

5. Safety & Usage Guidelines

• Regulatory Compliance: Certified by global authorities (FDA, EU CosIng, China NMPA); compliant with EU Cosmetic Regulation (EC) No 1223/2009 and China’s Cosmetic Safety Technical Specification.
• Recommended Dosage:
  • Hair care: 0.5%–3.0% (shampoos/conditioners); 1.0%–5.0% (styling products).
  • Skin care: 0.3%–2.0% (cleansers/moisturizers).
  • Industrial: 0.1%–1.0% (textile finishes/water treatment).
• Usage Notes:
  • Add to formulations at 25–40°C (avoid temperatures >60°C to prevent polymer chain degradation).
  • For alcohol-based systems, pre-dissolve in ethanol (1:3 ratio) before blending to ensure uniform dispersion.

6. Packaging & Storage

1. Packaging Forms

• Cosmetic/Industrial Grade:
  • 200L HDPE plastic drums (with inner liners) or 1,000L IBC totes — leak-proof, suitable for bulk shipping.
• Sample Sizes:
  • 1L/5L HDPE bottles (20% solid content) — for R&D or small-batch trials.

2. Storage Conditions

• Store in a cool, dry, well-ventilated area (temperature: 5–35°C, relative humidity: <75%); avoid direct sunlight and high temperatures (>40°C).
• Do not stack drums higher than 2 layers to prevent deformation and leakage.
• Shelf Life: Unopened containers — 18 months (20% solid grade) or 24 months (35% solid grade); use within 3 months after opening and reseal promptly.
