Sodium Carboxymethyl Cellulose (CMC) is a highly versatile chemical compound with applications spanning numerous industries. However, not all CMC is created equal. The effectiveness of CMC is heavily dependent on its grade, which is determined by factors such as the degree of substitution (DS), viscosity, and purity. As a leading carboxymethyl cellulose manufacturer and supplier, we understand the importance of selecting the right CMC grade for optimal performance.

Broadly, CMC grades can be categorized based on their intended applications: Food Grade, Pharmaceutical Grade, Industrial Grade (including Detergent, Textile, Paper Making, Ceramic, and Oil Drilling grades), and Toothpaste Grade. Each category has specific requirements for purity, viscosity, and other physical properties to ensure compliance and effectiveness.

Food Grade CMC, characterized by high purity (often 99.5% or higher), is primarily used as a thickener, stabilizer, and emulsifier in food and beverage products. Its ability to improve texture, mouthfeel, and shelf-life in items like ice cream, yogurts, sauces, and baked goods makes it invaluable. When you buy CMC food grade, ensure it meets relevant food safety standards.

Pharmaceutical Grade CMC adheres to stringent pharmacopoeial standards (e.g., USP, EP). It functions as a binder, disintegrant, suspending agent, and lubricant in tablets, capsules, suspensions, and ophthalmic solutions. Its low impurity profile and consistent viscosity are critical for drug safety and efficacy.

Industrial Grade CMC encompasses a wide array of applications. In detergents, it acts as an anti-redeposition agent to prevent soil from resettling on fabrics. For textiles, it serves as a thickening agent for printing pastes and a sizing agent. In oil drilling, CMC is used to control viscosity and fluid loss in drilling muds. Its water-retaining properties also make it useful in construction materials and ceramics. For these applications, businesses often look to purchase CMC from reliable industrial chemical suppliers.

When selecting a CMC product, consider the following: the required viscosity, the necessary purity level, the target application, and regulatory compliance. As a comprehensive CMC supplier in China, we offer a diverse portfolio of grades to meet these varied needs. Our technical team can assist you in identifying the most suitable CMC for your specific requirements.
