Hydroxyethyl cellulose (HEC)
Hydroxyethyl cellulose (HEC) polymer is a hydroxyethyl ether of cellulose, obtained by treating cellulose with sodium hydroxide and reacting with ethylene oxide.
HEC polymers are largely used as water-binder and thickening agent in many industry applications, that is, personal care products, pharmaceutical formulations, building materials, adhesives, etc., and as stabilizer for liquid soaps.
HEC polymers are available as white free-flowing granular powders that easily dissolve in cold and hot water to give transparent solutions with varying viscosities depending on polymer concentration, type and temperature.
Hydroxyethyl Cellulose (HEC) is a family of nonionic, water-soluble polymers that can thicken, suspend, bind, stabilize, disperse, form films, emulsify, retain water and provide protective colloid action.
Hydroxyethyl Cellulose (HEC) can be used to prepare solutions with a wide range of viscosities – including moderate viscosities with normal colloidal properties to maximum viscosities with minimal dissolved solids.
Other names : Cellulose, hydroxyethyl ether; Hydroxyethylcellulose; 2-Hydroxyethyl cellulose; Hyetellose; Natrosol; Cellosize; TYLOSE
Hydroxyethyl cellulose is a polysaccharide derivative with gel thickening, emulsifying, bubble-forming, water-retaining and stabilizing properties.
Hydroxyethyl cellulose is used as a key ingredient in many household cleaning products, lubricants and cosmetics due to its non-ionic and water-soluble nature.
Hydroxyethyl cellulose is often used as an ingredient in ophthalmic pharmaceutical preparations such as artificial tear solutions and adjunct agent in topical drug formulations to facilitate the delivery of drugs with hydrophobic character.
Hydroxyethyl cellulose (HEC) thickeners are made by chemically modifying cellulose with ethylene oxide.
This modification transforms cellulose that is insoluble in water, into a water-soluble polymer.
Dissolved HEC polymer thickens the water phase.
Also, the polymeric molecules are able to form a reversible three-dimensional (3D) network consisting of hydrogen bonds.
The hydroxyl (OH) groups of HEC thickeners can form hydrogen bonds with one another and with other components that are able to form hydrogen bonds.
At low shear, a waterbased system containing a HEC thickener has a high viscosity (or even a yield stress).
At high shear, the hydrogen bond network breaks down and the viscosity drops.

Main properties of Tylose® HEC are:
Thickening
Pseudoplasticity
Water retention
Protective colloide
Film forming
Due to its advantageous properties, hydroxyethyl cellulose is one of the most widely used cellulose ethers.
Tylose H-grades contribute to a singular and remarkable property profile in various products for different applications, e.g. for coatings, polymerizations and building materials.
Paints
There are many reasons why Tylose is an important component in water based paints for ceilings, walls and facades.
Paints
Application of paint should be smooth and easy, whilst spatter must be kept to a minimum.
To achieve these attributes only a small amount of Tylose is necessary.
Depending on the system being used, a concentration of 0.2 % - 0.5 % is typically required.
The choice of Tylose types depends on the application and requirements.
The most commonly used Tylose types in coating materials are Tylose HS and Tylose H.
Filter applications by:
Exterior paints
Exterior paints are used for decorative design as well as for protecting surfaces from the destructive influences of weathering.
Suitable substrates include renders (mineral and polymer based), concrete, brickwork and other coatings.
Interior paints
Interior emulsion paints, often just referred to as interior paints, belong to the group of most commonly used coatings.
Apart from their decorative and protective properties, they facilitate the cleaning of interior walls and ceilings.
For interior paints with low spattering the use of hydrophobic modified Tylose is recommended.
Solid paints
Solid paints and high-thixotropy paints are used exclusively in the do-it-yourself sector.
These kinds of paints are used for their decorative effects on interior walls and ceilings.
In addition to its colouring effects, with solid paints a surface structuring is achieved. Solid paints can only be used with special, purpose-designed rollers.
They have little tendency to spatter and so cause a minimum amount of mess. They cannot be tinted after manufacture.
Silicone resin paints
Silicone resin paints are predominantly used for exterior application.
They are a combination of a silicone resin emulsion and a polymer dispersion.
The formulation benefits from the combination of good pigment-binding power of the polymer emulsion with the excellent water-repellent properties of the silicone resin.
Tinters
Full colour paints or tinters are non-white emulsion paints.
They are used in concentrated form for colour coatings (full colour paints) or mixed with interior or exterior paints before use (tinters).
Tinters are compatible with a large number of emulsion paints.
Powder paints
Powder paints are dry paint formulations which are prepared by mixing them with water shortly before application.
They are used for both interior and exterior applications.
Powder paints have a number of environmental and economical advantages such as free from solvents and preservatives, reduced weight and packaging volume, low-cost packaging and stability against frost during storage.
Limewash paints
Limewash paints are aqueous slurries of slaked lime (lime hydrate) with added pigment.
The chemical reaction of the lime hydrate with atmospheric carbon dioxide results in a non-film forming coating which is not resistant to acidic gases.
Often, they have poor hiding power and several coatings must be applied.
Distempers
Distempers are among the oldest paints for interior use.
They are available as powders and paste-like form.
Apart from regulating the consistency of distempers, Tylose® also acts as binder. Distempers are not water resistant and cannot be painted over.
In today’s paint industry they are of minor importance.
Silicate paints
Silicate paints are based on silicate solutions.
After application, silification occurs and a non-continuous film is formed on the substrate.
This leads to an excellent water vapour permeability.
Silicate paints are often used for renovation as well as for the coating of older building fabrics.
Cement paints
Cement paints are supplied in powder form. After mixing with water, their pot life is limited.
Hydraulic hardening leads to a hard, porous surface.
They have only a moderate weathering resistance, particularly against driving rain and can only be coloured with inorganic, alkali-resistent pigments.
Glazes
Glazes give a transparent and/or translucent finish.
Very fine pigments with a high amount of binder are commonly used.
They act as a protection barrier and are used for the decorative design of interior and exterior walls.
Tylose® is used in glazes mainly to adjust the application properties.
Paint-stripping pastes
Paint-stripping pastes support and facilitate the removal of old coatings, by a partial dissolving effect or a chemical reaction.
They reduce the hardness and adhesion of coatings onto their substrates.
Subsequent mechanical removal is then greatly improved.
Ceramics
Tylose cellulose ethers are used by the ceramic industry in various applications such as ceramic and powder metallurgical extrusion mixes as rheology modification and water retention additives.
Ceramics
Furthermore, the high binding power of Tylose plays an important role in spray drying and agglomeration granuling and the related powder pressing processes.
Tylose is compatible with most other additives such as dispersants, plasticisers and surfactants.
It is easily integrable into existing formulations, and it shows an excellent debinding behaviour.
Extrusion
Tylose is an indispensable additive for the plastification of ceramic extrusion mixes, especially for the extrusion of technical ceramics, used in the automotive and chemical industry.
Typical examples are honeycomb catalyst substrates and particle filters for exhaust gas after-treatment applications.
Tylose shows fast hydration and swelling and unfolds its plastification and water retention effects in a highly efficient way.
With the combination of high thermal stability, high green strength and low fibre content, Tylose enables high extrusion rates, even with ultra-thin wall substrates.
In the drying process Tylose prevents cracks via its binding effect, additionally supported by its thermal gelation capabilities.
Powder metallurgy
In powder metallurgic extrusion applications, special Tylose grades provide an outstanding thickening effect in water and in certain compositions of organic solvents.
Engobes and glazes
The rheology modifying effects of Tylose prevent sedimentation of solids as well as supporting good flowability of the glazing slips, ensuring a uniform coating of ceramic bodies.
In a dry state, Tylose strengthens the capability of the glaze film to bind to the ceramic surface, making it smooth and stable.
Granuling and powder pressing
Tylose prevents sedimentation in spray drying slips and acts as rheology modifier.
It contributes to an advantageous particle size distribution of the dried granules and fast filling of pressing moulds.
In combination with plasticising and other additives, it provides high green strength and shows excellent debinding behaviour.
Tylose cellulose ethers are indispensable additives for a broad variety of ceramic applications.

Cellulose ethers are water-soluble polymers derived from cellulose that is the most abundant natural polymer.
For more than 60 years, these products have played a significant role in a host of applications, from construction products, ceramics, and paints to foods, cosmetics, and pharmaceuticals.
For construction products, cellulose ethers act as thickeners, binders, film formers, and water-retention agents.
They also function as suspension aids, surfactants, lubricants, protective colloids, and emulsifiers. In addition, aqueous solutions of certain cellulose ethers thermally gel, a unique property that plays a key role in a variety of applications.
These include ethyl cellulose, hydroxy ethyl cellulose, methyl cellulose, sodium carboxy methyl cellulose, and benzyl cellulose.
Ethyl and benzyl cellulose can be used as hot-melt adhesives.
Methyl cellulose is a tough material, completely nontoxic, tasteless, and odorless, which makes it a suitable adhesive for food packages.
It is capable of forming high-viscosity solutions at very low concentrations, so it is useful as a thickening agent in water-soluble adhesives.
Hydroxy ethyl cellulose and sodium carboxy methyl cellulose can also be used as thickeners.
The cellulose ethers have fair to good resistance to dry heat. Water resistance varies from excellent for benzyl cellulose to poor for methyl cellulose
Cellulose ethers are a major class of commercially important water-soluble polymers for the construction and building industries.
Cellulose ethers are capable of increasing the viscosity of aqueous media.
The viscosifying ability of a cellulose ether is primarily controlled by its molecular weight, chemical substituents attached to it, and conformational characteristics of the polymer chain.
Methyl cellulose (MC), methylhydroxyethyl cellulose (MHEC), ethylhydroxyethyl cellulose (EHEC), methylhydroxypropyl cellulose (MHPC), hydroxyethyl cellulose (HEC), hydrophobically modified hydroxyethyl cellulose (HMHEC) either alone or in combination are among the most widely used cellulose ethers in mortar formulations
