Carboxymethylcellulose SodiumThird Party Manufacturing in India

Carboxymethylcellulose (CAS 9004-32-4), typically formulated as Carboxymethylcellulose Sodium, works by providing lubrication and protection to the ocular surface, relieving dry eye symptoms. As a high-molecular-weight polymer, it acts as an ophthalmic demulcent that mimics natural mucins in tears. When applied to the eye, the polymer hydrates and binds to the corneal and conjunctival epithelial cells. This binding action increases the viscosity and stability of the tear film, preventing rapid evaporation and ensuring longer retention of moisture on the eye. The viscoelastic properties of Carboxymethylcellulose allow it to shear during blinking, which provides a smooth, low-friction protective barrier that reduces irritation and mechanical friction. By coating the ocular surface, it protects injured epithelial tissues from further environmental irritation, accelerates healing of the corneal surface, and restores comfort. Unlike lower viscosity lubricants, it provides sustained relief from dryness without causing significant, prolonged blurring of vision, making it highly suitable for daily management of ocular discomfort.

We provide comprehensive support for Carboxymethylcellulose third party manufacturing in India, delivering premium ophthalmic formulations to international distributors. Carboxymethylcellulose (CAS 9004-32-4) eye drops are widely used to treat ocular dryness and irritation, supporting patient eye health.

Therapeutic Uses

Carboxymethylcellulose is indicated for the treatment of:

• Dry Eye Syndrome: Alleviating dryness, burning, and irritation caused by insufficient tear production or rapid tear evaporation.
• Environmental Irritation: Protecting the eyes from wind, sun, smoke, dust, and prolonged computer screen exposure.
• Post-Surgical Lubrication: Soothing the eyes and promoting corneal epithelial healing after refractive or cataract surgeries.

Choosing a Carboxymethylcellulose Manufacturer

For eye care brands and third party buyers, partnering with a WHO-GMP certified Carboxymethylcellulose manufacturer is critical to ensuring product quality. Ophthalmic formulations demand absolute sterility and precise chemical stability.

The manufacturing of Carboxymethylcellulose eye drops requires advanced sterile liquid filling lines, typically utilizing blow-fill-seal (BFS) technology. Our manufacturing partners operate WHO-GMP certified facilities that produce Carboxymethylcellulose 0.5% w/v and 1% w/v drops. This ensures that ophthalmic distributors, PCD franchise owners, and export businesses receive exceptionally pure, sterile products that meet rigorous IP, BP, and USP standards.
