  2. Thermally reversible gelation behavior—forms clear, non-ionic gels upon heating and re-dissolves upon cooling.

  3. Outstanding film-forming capability with good flexibility, clarity, and barrier properties.

  4. Consistent batch-to-batch performance ensured by Ashland’s stringent GMP-compliant manufacturing controls.

  5. Low ash content and high purity, meeting requirements for pharmaceutical and food-contact applications where applicable.

Typical Applications Of Ashland Benecel K99C Methyl Cellulose

  1. Pharmaceutical tablet coatings and controlled-release matrix formulations.

  2. Water-based adhesives and construction mortars requiring extended open time and sag resistance.

  3. Personal care gels and emulsion stabilizers in leave-on and rinse-off products.

  4. Food-grade thickeners and texturizers in dairy alternatives and plant-based beverages.

  5. Ceramic tile adhesive additives to enhance workability and bond strength under variable humidity conditions.
