Cellulose ethers are modified cellulose compounds with versatile uses across various industries due to their solubility in water and ability to form gels, thicken, and stabilize. Key applications include:
1. **Construction**: Cellulose ethers, like hydroxypropyl methylcellulose (HPMC), are used in cement and mortar to improve water retention, workability, and adhesion. They help prevent cracks and enhance the durability of construction materials.
2. **Pharmaceuticals**: As inactive ingredients, cellulose ethers act as thickeners, binders, and stabilizers in tablets and capsules. They also serve as coating agents, helping to control drug release rates.
3. **Food Industry*
