FAQS on use of carboxymethylcellulose

Q: What is the primary use of carboxymethylcellulose?

A: Carboxymethylcellulose (CMC) is primarily used as a thickening, stabilizing, and binding agent in food, pharmaceuticals, and cosmetics. It enhances texture and viscosity in products like ice cream and lotions. Its water-retention properties also make it useful in industrial applications.

Q: How is carboxymethylcellulose used in eye drops?

A: Carboxymethylcellulose in eye drops acts as a lubricant to relieve dryness and irritation. It forms a protective layer on the ocular surface, retaining moisture. This makes it ideal for treating conditions like dry eye syndrome.

Q: What distinguishes sodium carboxymethylcellulose from standard CMC?

A: Sodium carboxymethylcellulose is the sodium salt form of CMC, offering higher solubility and stability in aqueous solutions. It is commonly used in pharmaceuticals, including artificial tears. Its enhanced properties make it suitable for sensitive applications like eye care.

Q: Is carboxymethylcellulose safe for use in pharmaceutical products?

A: Yes, carboxymethylcellulose is generally recognized as safe (GRAS) by regulatory bodies for pharmaceutical and food use. It is non-toxic, non-allergenic, and biocompatible. However, purity grades must align with intended applications to ensure safety.

Q: Can sodium carboxymethylcellulose cause side effects in eye drops?

A: Side effects from sodium carboxymethylcellulose in eye drops are rare and typically mild, such as temporary blurred vision or discomfort. These effects usually resolve quickly. Consult a healthcare provider if irritation persists.
