Granular Carboxymethyl Cellulose (G-CMC) is a high molecular weight cellulose ether compound made from natural cellulose through chemical modification. The introduction of carboxylmethyl groups into granular carboxymethyl cellulose's molecular structure makes it water-soluble, thickening, dispersible and stable. Granular carboxymethyl cellulose is a granular product, which is different from powder or fiber, and has better fluidity and operability.
From an industrial application perspective, the granular physical form of G-CMC significantly improves handling safety, dosing accuracy, and on-site operability compared with powder CMC. This makes Granular Carboxymethyl Cellulose particularly suitable for large-scale production environments such as oilfield drilling, mining, food processing, and pharmaceutical manufacturing, where stable quality, repeatability, and process efficiency are critical.
Core Application Areas
-
1. Granular carboxymethyl cellulose in food industry
The main functions of granular carboxymethyl cellulose in the food industry are as follows: in the food industry, it can be used as a food thickener, stabilizer (such as yogurt, ice cream), water-holding agent (baked food), and emulsifier.
Advantages of granular carboxymethyl cellulose: it forms an elastic colloid by combining with water molecules in food. It can also improve the texture and taste of food and extend the shelf life of the product.

2. Hondo granular carboxymethyl cellulose used in the pharmaceutical industry
Granular carboxymethyl cellulose has the following main uses in the pharmaceutical industry: tablet adhesive, sustained-release carrier, and ointment base.
One of the viscosity characteristics of granular carboxymethyl cellulose provides support for its bonding effect in the production of pharmaceutical tablets. At the same time, low-substituted granular carboxymethyl cellulose can be used as a sustained-release carrier for some tablet preparations because of its good disintegration effect. It can slowly release the drug effect after the drug enters the human body, and better play a therapeutic role.

3. Hondo granular carboxymethyl cellulose is used in daily chemical products
Granular carboxymethyl cellulose can be used in toothpaste, shampoo, and facial masks. In the production process of toothpaste, the unique molecular structure of cellulose is that granular carboxymethyl cellulose swells after combining with the water in the toothpaste, which can play a supporting role and become a good excipient, so that the toothpaste can be in a good state during use. In shampoo, granular carboxymethyl cellulose solution has a good suspension effect, which can make the active substances in the shampoo evenly dispersed, so that customers have a good experience during use. In facial masks, granular carboxymethyl cellulose mainly plays a role in water retention and moisturizing. It can lock water molecules and keep the skin moisturized for a long time.

4. Application of Hondo granular carboxymethyl cellulose in the petroleum industry
Granular CMC and Granular PAC is mainly used as a drilling fluid viscosity enhancer, filtration loss additive and dehumidifier in drilling, which can improve the mud's chip carrying capacity and protect the drill bit to prevent the well wall from collapsing. In addition, due to its rapid dissolution effect, granular carboxymethyl cellulose and polyanionic cellulose can greatly improve the efficiency of mud configuration in oil fields and improve work efficiency. Its unique network molecular structure can also play a good role in heat resistance and salt resistance, and is suitable for deep well and high-salt mine operations.
Features: High temperature resistance and salt resistance.

Ceramics: body enhancer.
Textiles: printing and dyeing paste thickener.
Papermaking: surface sizing agent.
Application Problem and Solutions
Stabilizing Texture & Moisture in Dairy Systems with Granular CMC
Food manufacturers often face texture instability, whey separation, and moisture loss during storage.
Granular CMC Solution:
Granular form allows dust-free feeding and uniform hydration, ensuring stable viscosity development and consistent mouthfeel across batches, especially suitable for continuous production lines.
Oil drilling Industry Field Challenge:
Powder CMC causes dust pollution, slow hydration, and inconsistent mud performance on-site.
Granular CMC Advantage:
Fast wetting, reduced fish-eyes, and controlled viscosity development make Granular CMC ideal for automated mud mixing systems and harsh drilling environments.
Functional Properties
Thickening and Suspension
Hondo Chem granular carboxymethyl cellulose can quickly dissolve in water and then form a high-viscosity colloidal solution. It is widely used in food, coatings and other fields. As a thickener and suspension stabilizer, granular carboxymethyl cellulose is conducive to the dispersion and synergy of other chemicals.
Water Retention and Film Formation
The unique network molecular structure of Hondo granular carboxymethyl cellulose and granular PAC can lock in moisture after combining with water molecules in bread and dairy products, extending the shelf life of such products.
Granular carboxymethyl cellulose or Granular Polyanionic Cellulose quickly combines with water to form a colloidal film on the surface of the product. Good film-forming properties make it suitable for drug coating or food preservation coating.
Biocompatibility
Granular sodium carboxymethyl cellulose or Granular Polyanionic Cellulose is non-toxic and degradable, suitable for the pharmaceutical and food industries. At the same time, it can synergize with other colloidal products to better achieve thickening and stabilization effects.
Advantages Of Hondo Granular Type
1. Granular Carboxymethyl Cellulose (CMC) do not have agglomeration when in contact with water, which can improve work efficiency.Optimized particle size and surface structure allow Hondo Granular CMC to hydrate evenly without fish-eyes. This ensures faster dissolution, predictable viscosity development, and stable performance in large-scale mixing, helping manufacturers shorten processing time and improve batch consistency.
2. Granular carboxymethyl cellulose or PAC has a good fluidity, easy for automatic metering and transportation.High flowability enables smooth feeding in silos and screw feeders, reducing blockage and dosing deviation. This makes granular CMC ideal for automated production lines, improving formulation accuracy and operational efficiency for bulk and industrial users.
3. Granular carboxymethyl cellulose or PAC has less dust, improves the working environment.Low-dust granular form minimizes airborne particles during handling and feeding, improving workplace safety and cleanliness. It also reduces material loss and supports food-grade and industrial production standards required by international buyers.
4. Granular carboxymethyl cellulose or PAC has a high bulk density, saves storage space.Higher bulk density allows more material per unit volume, reducing storage and transportation costs. This logistics advantage is especially valuable for exporters, distributors, and long-term bulk procurement customers seeking cost efficiency.
