Polyquaternium-7

Description

1. Product Overview
Polyquaternium-7 is a high-performance, cationic copolymer of acrylamide and diallyldimethylammonium chloride, engineered for superior conditioning and rheology control. It is primarily used as a film-forming and conditioning agent in personal care formulations, as well as a flocculant in industrial water treatment. The key value proposition lies in its exceptional ability to deliver soft, manageable hair and skin feel without buildup, while simultaneously enhancing process efficiency in wastewater clarification. Strategically, Polyquaternium-7 is critical for manufacturers seeking to balance premium end-product performance with regulatory compliance and cost-efficient operations in a tightening global supply chain for specialty polymers.

• Solid content: 8–10% (typical), 9.0% ± 0.5%

• Viscosity (Brookfield, 25°C): 8,000–15,000 cP

• pH (neat): 5.0–7.0

• Charge density: High (approx. 1.2–1.6 meq/g)

• Density (25°C): 1.02–1.06 g/cm³

• Packaging options: 200 kg HDPE drums, 1,000 kg IBC totes, bulk tanker (20 MT)

• Shelf life: 24 months when stored in original sealed containers at 5–35°C, away from freezing and direct sunlight

3. Core Industrial Applications

• Personal care & cosmetics (primary industry):

  • Shampoos, conditioners, body washes, and styling gels – Provides smooth wet combing, reduced flyaways, and a silky after-feel.

  • Why superior: Unlike Polyquaternium-10 or -11, Polyquaternium-7 offers higher substantivity to damaged hair and better compatibility with anionic surfactants, reducing the need for multiple conditioning agents.

• Industrial water treatment:

  • Primary coagulation and flocculation in municipal and industrial effluent – Agglomerates suspended solids and colloids.

  • Performance advantage: Achieves faster settling rates and clearer supernatant than nonionic or anionic polymers, especially in high-turbidity or variable-pH streams.

• Textile & paper processing:

  • Antistatic treatment and surface modification – Reduces static charge on synthetic fibers and improves paper wet strength.

  • Cost advantage: One-step application replaces separate antistat and binder, lowering chemical inventory and labor costs.

• Enhanced oil recovery (EOR) – niche use:

  • Friction reducer in water injection – Outperforms conventional PAM in high-salinity brines due to cationic stability.

4. Competitive Advantages

• Quality consistency: Batch-to-batch solid content and viscosity variance < ±2% (ISO 9001:2025 certified production).

• Supply reliability: Dual-sourced raw materials (acrylamide and DADMAC) with strategic warehousing in North America, Europe, and Southeast Asia.

• Logistics capability: 48-hour dispatch for drum/IBC orders; 10-day lead time for bulk tankers.

• Price competitiveness: Cost per active solid 12–18% below European and North American branded equivalents, with volume-based tiered pricing.

• Sustainability: Low-residual monomer (< 5 ppm acrylamide) – compliant with EU REACH and US EPA Safer Choice criteria.

• Technical support: Full documentation including CoA, MSDS, TDS, and formulation guides; direct access to application engineers for optimization trials.
