Absorbent Cotton Wool Roll 500g

Description

1. Product Overview

The Absorbent Cotton Wool Roll (500g) is a high-purity, medical-grade nonwoven cotton substrate engineered for superior fluid absorption and particle entrapment in clinical, pharmaceutical, and industrial hygiene applications. Its primary industrial use includes wound care management, surgical preparation, equipment cleaning in sterile environments, and filtration layering in medical device assembly. The key value proposition lies in its consistent hydrophilic performance, low non-absorbent residue, and lint-free composition—directly reducing procedure risk and operational waste. As global infection control protocols tighten, this product serves as a strategically critical consumable for ensuring compliance, patient safety, and process efficiency across healthcare supply chains.

2. Key Specifications & Technical Characteristics

• Material Composition: 100% pure cotton (Gossypium spp.), bleached without optical brighteners; free from synthetic fibers, adhesives, and chemical contaminants

• Purity Grade: USP/EP compliant (Type I – Highly Absorbent Cotton); meets ISO 11145:2019 for medical textiles

• Physical Characteristics:

  • Form: Continuous roll, evenly carded and pleated

  • Color: White (natural bleached, no dyes)

  • Fiber length: 15–25 mm

  • Absorbency rate: < 5 seconds (sinking time, distilled water, 23°C)

  • Water retention capacity: ≥ 24 g water / g cotton (dry weight basis)

  • Density: 2.8–3.2 g/cm³ (rolled)

• Packaging Options: Sealed PE-lined kraft roll bag with tamper-evident closure; bulk case: 24 rolls per carton

• Shelf Life: 5 years from manufacture when stored in dry, ventilated conditions (RH < 65%, temp 5–30°C)

3. Core Industrial Applications

• Healthcare & Hospital Supply Chains: Used for wound exudate management, surgical swabbing, and pre-operative skin preparation—outperforms synthetic alternatives due to higher fluid capacity and lower risk of fiber shedding.

• Pharmaceutical Manufacturing: Critical for cleaning filling lines, tablet press dies, and vial stoppers. The lint-free structure eliminates contamination risk, reducing batch rejection rates by an estimated 12–18% compared to blended polyester rolls.

• Dental & Veterinary Clinics: Provides rapid hemostasis during extractions or minor surgeries; superior cost-efficiency vs. gauze sponges per gram of absorbent material.

• Industrial Hygiene & Spill Control: Used in cleanrooms and electronics assembly to wick solvents and oils without scratching sensitive surfaces. The 500g roll size minimizes changeover downtime versus smaller retail units.

4. Competitive Advantages

• Quality Consistency: Batch-to-batch coefficient of variation (CV) for absorbency < 3% – verified via ISO 13485-certified testing protocols.

• Supply Reliability: Dual-source raw cotton supply contracts (India, Brazil) with 99.2% on-time delivery performance across 36 months.

• Logistics Capability: Direct container loading from port of origin; expedited customs documentation (CPC 9801.00.10 eligible in select markets).

• Price Competitiveness: 8–14% lower total landed cost than EU/US equivalent grades due to vertically integrated ginning and bleaching.

• Sustainability: Biodegradable and compostable (EN 13432); zero chlorine bleaching – hydrogen peroxide process; carbon-neutral roll transport available for orders ≥ 10 pallets.

• Technical Support: Full certificate of analysis (CoA), safety data sheet (SDS), and sterility validation protocol provided; on-call application engineering for integration into automated dispensing systems.

5. Commercial & Supply Information
