    Hydroxyethyl Cellulose CAS 9004-62-0

    Hydroxyethyl Cellulose (CAS 9004-62-0), commonly abbreviated as HEC, is a non-ionic, water-soluble polymer derived from alkali cellulose, utilized primarily as a high-performance thickening agent and rheology modifier in latex paints and architectural coatings. This Cellulose hydroxyethyl ether functions by forming a pseudoplastic network in aqueous phases, providing superior biostability and color acceptance compared to standard cellulose derivatives. As a versatile 2-Hydroxyethyl cellulose ingredient, it acts as a critical protective colloid and water-retention agent in cementitious building materials and joint compounds, ensuring workability and open time. We provide this industrial polymer with competitive factory pricing to support coating manufacturing and ensure bulk supply availability for continuous production. Our facility accommodates customized specifications for viscosity ranges (from low to high) and hydration times, while every shipment is fully documented with MSDS, TDS, COA files to meet technical and regulatory standards.

    • Enhances leveling and color uniformity

    2. Construction & Building Materials

    • Cement and gypsum-based plasters
    • Tile adhesives and grouts
    • Self-leveling compounds and crack fillers

    Key functions:

    • Strong water retention to improve cement hydration
    • Better workability and open time
    • Reduced shrinkage and improved bonding

    3. Oilfield Chemicals

    • Drilling fluids and completion fluids
    • Workover and fracturing fluids

    Key functions:

    • Controls fluid rheology and viscosity
    • Enhances carrying capacity for cuttings
    • Good salt tolerance and filtration control when properly formulated

    4. Household & Personal Care

    • Liquid detergents and cleaners
    • Shampoo, body wash, hand wash
    • Creams and lotions (where non-ionic thickener is preferred)

    Key functions:

    • Gentle thickening with smooth flow
    • Stabilizes emulsions and suspensions
    • Provides desirable skin-feel and product appearance

    5. Other Industrial Uses

    • Polymerization aid
    • Adhesives and binders
    • Ceramic and pigment suspension systems

    Storage Conditions

    • Store in a cool, dry and well-ventilated warehouse.
    • Keep away from moisture, rain and direct sunlight to prevent caking or premature gel formation.
    • Maintain the packaging tightly sealed when not in use.
    • Recommended storage temperature: ≤ 30 °C, avoid proximity to heat sources.
    • Avoid long-term storage in high humidity environments.

    Safety Precautions

    Hydroxyethyl Cellulose is generally regarded as low-toxicity and safe for normal industrial handling. However, as with all fine powders and industrial chemicals, basic precautions should be followed:

    • Avoid generating excessive dust during handling, charging or mixing.
    • Use local exhaust ventilation in dusty areas.
    • Wear suitable dust masks/respirators, protective goggles and gloves during handling.
    • Avoid inhalation of dust and prolonged contact with eyes or skin.
    • In case of contact with eyes, rinse immediately with plenty of water and seek medical attention if irritation persists.
    • Clean up spilled material carefully (avoid dry sweeping that may create dust; vacuum or gently shovel into suitable containers).
    • Do not discharge large quantities into drains or natural water sources.

    FAQ - Technical & Supply Chain

    • Q:

      How does the non-ionic nature of CAS 9004-62-0 affect its industrial application?

      A: CAS 9004-62-0 identifies Hydroxyethyl Cellulose as a non-ionic ether, which ensures it remains chemically inert and stable in formulations containing high salt concentrations or dissolved electrolytes, unlike anionic thickeners like CMC.
    • Q:

      Is this polymer suitable for water-based latex paints?

      A: Yes, this material is specifically intended for use in water-based latex paints to control viscosity, improve brushability, and prevent pigment settling during storage.
