CARBOCEL® derivatives are used in various markets for their qualities as rheology modifiers, water entraining agents, stickers and filming agents. 

Cellulosic Ethers

Cellulosic Ethers

Cellulose is the most diffuse natural polymer in the world.  Cellulose itself is unsoluble and could be difficultly used in industrial applications. 

Chemical modifications of cellulose can lead to soluble products which offer a wide range of functional solutions to many applications.
Carboxymethylcellulose (CMC) is probably the most useful derivative of cellulose and Lamberti is one of the major players in the world.

Lamberti started the production of CMC in 1958 and has progressively improved its production processes and differentiated the range.
Today the  CARBOCEL® brand counts more than 50 derivatives that differ in the Degree of Substitution, Molecular Weight,  Purification Degree and consequently in their applications and function of use. 

Main Applications

  • Surface Treatment: Cellulose-based thickeners for waterborne coatings, providing viscosity control and tailored rheological behaviour for decorative and protective applications.
  • Textile — Thickeners for reactive and disperse dye printing, with selected grades used as antimigration agents in fabric pretreatments for digital printing.
  • Ceramics — Binders and thickeners for glazes and engobes, controlling rheology and consolidating the unfired layer to support consistent glazing and reduce surface defects.
  • Food and Beverage — Purified cellulose gums for food and beverage formulations, providing thickening, stabilisation and water retention while improving texture and mouthfeel.
  • In H&PC it can be used in oral care, including toothpaste as well as as thickeners, stabilizers and anti-redeposition aids for detergent formulations. 
  • in Wet End Paper is used to enhance dry paper strength and support wet-strength performance.
  • Other applications include viscosifiers and fluid loss reducers for water-based drilling fluids used in oil and gas operations (Energy Solutions).
