Pharmacueticals:
1. Binding agent: HPMC acts as a dry binder in tablet manufacturing, improving granule cohesion and tablet hardness.
2. Disintegrant: Facilitates rapid disintegration of tablets in aqueous environments.
3. Controlled-release matrix: Forms gel networks for sustained drug release, especially in oral dosage forms.
4. Film forming agent:
Enteric coatings: Provides pH-dependent release by forming films that resist dissolution in acidic conditions but release in alkaline environments.
Immediate-release coatings: Enhances tablet stability and appearance.
5. Lubricant: Used in artificial tears and eye drops to improve viscosity and retention on ocular surfaces.
Capsule application: HPMC is widely used as a non-animal-derived capsule shell material to replace traditional gelatin capsules, particularly suitable for vegetarian, religious, or allergy-sensitive populations.

Cosmetics:
1. Thickening Agent
Liquid products: Used in shampoos, shower gels, and liquid soaps to improve viscosity and texture.
Gels: Acts as a gelling agent in transparent gels for skincare or hair styling products.
2. Stabilizer & Emulsifier
Emulsions: Prevents phase separation in creams and lotions by stabilizing oil-water interfaces45.
Suspensions: Maintains uniform dispersion of solid particles in scrubs or masks.
3. Moisture Retention
Hydrating creams: Enhances water retention in moisturizers, prolonging skin hydration.
Leave-on treatments: Reduces water evaporation in serums or overnight masks.
4. Film-Forming Agent
Hairsprays & styling products: Forms flexible films for hold without stiffness.
Peel-off masks: Creates a film that can be removed easily after drying

Foods:
1. Thickening & Stabilizing Agent
Sauces & dressings: Improves viscosity and prevents separation in ketchup, mayonnaise, and salad dressings.
Dairy products: Acts as a stabilizer in yogurt and ice cream to enhance texture and prevent ice crystal formation.
2. Emulsifier & Water Retention
Baked goods: Retains moisture in bread and cakes, extending shelf life.
Meat products: Enhances water binding in processed meats like sausages
3. Film-forming & Coating
Edible films: Used for food packaging to extend freshness (e.g., fruit coatings).
Confectionery: Provides gloss and prevents sticking in candies

Package: 25kg/Drum
