Hydroxyethyl Cellulose (HEC) is a nonionic, water-soluble cellulose ether with excellent thickening, film-forming, stabilizing, and water-retention properties. It is inert, non-toxic, and compatible with most additives, making it widely used in pharmaceuticals, cosmetics, construction, coatings, textiles, and other industries.
1. Pharmaceutical Industry
Thickener & Stabilizer: Used in oral suspensions, eye drops, topical gels, and creams to adjust viscosity, prevent sedimentation of active ingredients, and improve product stability. It ensures uniform drug distribution and enhances user compliance.
Film Coating Agent: Forms a thin, transparent, and flexible film on tablets and capsules, improving their appearance, masking bitter tastes or odors, and protecting drugs from moisture and oxidation.
Binder: Assists in granulation and tablet compression, improving the strength and integrity of tablets without affecting their disintegration and drug release rate.
Excipient for Controlled Release: Used in sustained-release formulations as a matrix material to regulate the release rate of drugs, achieving long-acting therapeutic effects.
2. Cosmetics & Personal Care
Rheology Modifier & Thickener: The core application in cosmetics—used in shampoos, conditioners, body washes, lotions, and creams to adjust product viscosity, create a smooth texture, and prevent phase separation.
Film Former & Moisturizer: Forms a breathable protective film on the skin and hair, locking in moisture, reducing water loss, and improving skin hydration and hair softness.
Stabilizer: Stabilizes emulsions (oil-in-water) in products like facial creams and sunscreens, preventing oil-water separation and extending product shelf life.
