Sodium Carboxymethyl Cellulose FAQs

Q: What are the primary applications of カルボキシメチルセルロースナトリウム in the food industry?

A: カルボキシメチルセルロースナトリウム (Sodium CMC) is widely used as a thickener, stabilizer, and emulsifier in foods like ice cream, salad dressings, and bakery products. It prevents ice crystal formation in frozen desserts, improves texture in sauces, and acts as a fat replacer in low-calorie products.

Q: How does carboxy methyl cellulose differ from other cellulose derivatives?

A: Carboxy methyl cellulose (CMC) stands out for its high water solubility and ability to form viscous solutions at low concentrations. Unlike methylcellulose or hydroxypropyl methylcellulose, CMC has carboxymethyl groups that enhance its ionic properties, making it ideal for applications requiring pH stability and electrolyte tolerance.

Q: What safety regulations apply to sodium CMC in pharmaceutical formulations?

A: Sodium CMC is classified as GRAS (Generally Recognized as Safe) by the FDA and is approved in pharmaceuticals as an excipient for tablets, ophthalmic solutions, and topical creams. It must meet USP/NF purity standards, with limits on heavy metals and microbial contaminants.

Q: Can カルボキシメチルセルロースナトリウム be used in water treatment processes?

A: Yes, カルボキシメチルセルロースナトリウム acts as a flocculant and stabilizer in water treatment. Its anionic nature helps remove heavy metals and suspended particles by binding to contaminants, improving sedimentation efficiency in industrial and municipal wastewater systems.

Q: How does the degree of substitution (DS) affect the properties of carboxy methyl cellulose?

A: The DS of カルボキシメチルセルロース influences its solubility, viscosity, and salt tolerance. Higher DS (0.8–1.2) provides better solubility in acidic conditions and resistance to electrolytes, making it suitable for acidic foods and personal care products. Lower DS grades (0.5–0.7) are preferred for applications requiring gel formation, such as in ceramic glazes.
