About Aqualon sodium carboxymethylcellulose Chemistry: Cellulosics

Aqualon sodium carboxymethylcellulose

Chemistry: Cellulosics

Aqualon sodium carboxymethylcellulose (CMC) is made by reacting sodium monochloroacetate with alkalicellulose under rigidly controlled conditions. The resultant anionic polymer is purified and dried. Purified CMC for personal care and cosmetic applications is typically sold at 99.5 percent minimum purity. In addition to thickening aqueous systems, CMC is used in personal care products for water binding, syneresis control and its ability to suspend pigments and active ingredients in solution. Aqualon CMC is an anionic, water-soluble polymer.

A variety of CMC grades are available, with varying degrees of substitution, viscosities and particle sizes. S-types provide smooth solutions, based on uniform substitution. O-types provide solubility and viscosity stability on storage in low pH media. Aqualon CMC grades designated P or PH are compliant with the monograph requirements of the National Formulary.

Ashland provides cellulose gum under the trade names Aqualon, Blanose and Bondwell depending on the region in which we serve you.

Versatile Thickening and Stabilizing Agent

Aqualon sodium carboxymethylcellulose is widely utilized for its thickening, stabilizing, and binding properties across multiple industries. Its solubility in water and stable performance within a broad pH range make it ideal for applications ranging from food and beverages to pharmaceuticals, cosmetics, and industrial products. The technical grade quality ensures consistency, safety, and ease of formulation.

Safe, Sustainable, and Biodegradable Choice

With a high purity level above 99% and a composition free from significant heavy metals, Aqualon sodium carboxymethylcellulose provides non-toxic performance. Its biodegradability aligns with sustainable practices in modern manufacturing, while the absence of odor and low impurities supports sensitive applications such as in food and personal care products.

FAQs of Aqualon sodium carboxymethylcellulose Chemistry: Cellulosics:

Q: How is Aqualon sodium carboxymethylcellulose typically used in various industries?

A: Aqualon sodium carboxymethylcellulose serves as a thickener, stabilizer, binder, and film-former in applications such as food production, pharmaceuticals, personal care products, and industrial processes. Its ability to dissolve in water and modify viscosity makes it valuable for formulating gels, suspensions, coatings, and emulsions.

Q: What are the main benefits of using Aqualon sodium carboxymethylcellulose in formulations?

A: Key benefits include its non-toxic and odorless nature, biodegradability, wide pH stability (pH 410), and high purity (>99%). It helps achieve desired viscosity and stability, improves texture and consistency in products, and can be used safely in consumer goods.

Q: When should I use a specific viscosity grade of Aqualon sodium carboxymethylcellulose?

A: The viscosity grade required depends on the desired end products thickness or flow properties. For thinner formulations, select a lower-viscosity grade (around 400 mPas), while thicker gels or heavy-duty binding may call for higher-viscosity grades (up to 8000 mPas). The selection is application-specific, so consult technical data for optimal performance.

Q: Where should Aqualon sodium carboxymethylcellulose be stored to ensure quality and shelf life?

A: Store the product in a cool, dry place in its original 25 kg bag packaging. Proper storage conditions will prevent moisture absorption and help maintain the products quality throughout its 24-month shelf life.

Q: What is the process for dissolving Aqualon sodium carboxymethylcellulose in water?

A: Gradually add the powder into water while stirring continuously to avoid clumping and ensure even dispersion. Mixing at room temperature is usually sufficient; using hot water can increase dissolution speed for some grades, but always refer to supplier guidelines for best results.

Q: Is Aqualon sodium carboxymethylcellulose safe and environmentally friendly for use in food and personal care?

A: Yes, it is non-toxic, odorless, biodegradable, and tested for low levels of heavy metals (<20 ppm) and impurities. Its high purity and consistent quality make it suitable for use in food, pharmaceuticals, and personal care products while supporting sustainable, environmentally responsible practices.
