Description
Hetastarch, another nonproteinaceous colloid, is a complex mixture of ethoxylated amylopectins ranging in molecular weight from 10 to 1,000 kDa (average molecular weight, ~450 kDa).
When infused as a 6% solution, hetastarch approximates the activity of human albumin.
The larger molecular weights, however, increase its intravascular residence time as well as its plasma expansion effects relative to albumin.
Hetastarch is synthetically produced, so it is degraded more slowly and is less antigenic than other colloids.
Despite these advantages, hetastarch is quite expensive and also has no oxygen-carrying capacity.

Definition
A starch derivative containing 90% amylopectin.
Production Methods
A purified form of cellulose is reacted with sodium hydroxide to produce a swollen alkali cellulose, which is chemically more reactive than untreated cellulose.
The alkali cellulose is then reacted with ethylene oxide to produce a series of hydroxyethyl cellulose ethers.
The manner in which ethylene oxide is added to cellulose can be described by two terms, the degree of substitution (DS) and the molar substitution (MS).
The DS designates the average number of hydroxyl positions on the anhydroglucose unit that have been reacted with ethylene oxide.
Since each anhydroglucose unit of the cellulose molecule has three hydroxyl groups, the maximum value for DS is 3.
MS is defined as the average number of ethylene oxide molecules that have reacted with each anhydroglucose unit.
Once a hydroxyethyl group is attached to each unit, it can further react with additional groups in an end-to-end formation.
This reaction can continue and there is no theoretical limit for MS.

Hydroxyethylcellulose is used as a gelling and thickening agent in the development of biostructures for the delivery of hydrophobic drugs.
Hydroxyethylcellulose is used in the development of polymer networks and block copolymers useful in separation technology such as capillary electrophoresis and in biofilms and coatings.
Hydroxyethylcellulose is a non-ionic, water soluble polymer used as a thickening agent for aqueous cosmetic and personal care formulations.
Hydroxyethyl cellulose will produce crystal clear gel products and thicken the aqueous phase of cosmetic emulsions.
Hydroxyethyl cellulose can be also be used to efficiently thicken shampoos, body washes and shower gels.
One of the problems normally associated with this and other water-soluble thickeners is the tendency of the particles to agglomerate or lump when first wetted with water.
The high-purity cosmetic grade of Hydroxyethylcellulose we offer is an R-grade, designed to be added to water without lumping, and thus greatly facilitating solution preparation.
Hydroxyethyl cellulose is also the most efficient grade of non-ionic thickener available from the manufacturer.
Hydration of the R-grade particles has been inhibited.
When the particles are added to water, they disperse without lumping, and following a predetermined delay, begin to dissolve.
This process permits the preparation of clear, smooth, viscous solutions in a short period of time by simply adding the R-grade to water and stirring until the polymer is completely dissolved to prevent settling of the particles.
The inhibition period, from the initial wetting to the start of dissolution, is referred to as the hydration time.
This hydration time can vary from 4-25 min.
Hydration time is markedly affected by two factors: pH and temperature of the water.
A higher temperature and a higher pH decrease the hydration time, but a too high temperature or pH can result in lumping.
So, it is recommended that it be added to room temperature water with a neutral pH.
Once hydrated, it can be heated and the pH can be adjusted as may be needed.
PROPERTIES AND APPLICATIONS
Hydroxyethyl cellulose (HEC) is an important non-ionic, water-soluble cellulose derivative.
Hydroxyethyl cellulose is a completely odorless, tasteless, and non-toxic white to light-yellow powder that readily dissolves in hot and cold water but is insoluble in most organic solvents.
When dissolved in water, it forms a transparent viscous solution which has a non-Newtonian behavior.
The hydroxyl groups of Hydroxyethyl cellulose present in the side chains can be reacted with hydrophobic moities to modify the properties of HEC.
For example, attaching polyether chains onto the cellulose (alkoxylation) yields hydrophobically modified Hydroxyethyl cellulose (HMHEC).
Hydroxyethyl cellulose is an associative thickener that forms a reversible three-dimensional supramolecular network in solution through intra- and intermolecular associations of the hydrophobic groups.
Hydroxyethyl cellulose is mainly used in water-based products.
Hydroxyethyl cellulose finds applications as a binder, film former, rheology modifer (thickener), adhesion promoter, dispersion stabilizer, extender and slumping reducer in numerous products including paints, inks, adhesives, cosmetics, personal care products, textiles, cements, ceramics and paper products.
One of the most important applications of Hydroxyethyl cellulose and HMHEC are waterborne architectual coatings.
They are either used alone or in combination with other thickeners.
Infact, Hydroxyethyl cellulose is the most widely used thickener in exterior latex paints because it is compatible with many coating ingredients such as pigments, surfactants, emulsifiers, preservatives, and binders.
Hydroxyethyl cellulose (EHEC) is a non-ionic, water-soluble cellulose derivative produced by introduction of ethylene oxide groups to the hydroxyl groups of the cellulose backbone.
Hydroxyethyl cellulose is useful as a water thickener, rheological control additive, protective colloid, binder, stabilizer, suspending agent and film former.
Hydroxyethyl cellulose is used in many industrial applications including latex paints, emulsion polymerization, petroleum, paper, pharmaceuticals, cosmetics and many other applications.

Hydroxyethylcellulose is derived from cellulose, a polysaccharide that is the most abundant biopolymer in nature and found in the cell walls of plants as well as in wood and cotton.
Hydroxyethylcellulose is used extensively in the personal care industry as a thickening agent.
Hydroxyethyl cellulose is nonionic (not affected by pH) and soluble in water, thereby providing it with the capacity to thicken the aqueous phase of a formulation.
Hydroxyethyl cellulose also has reported uses as a binding agent, emulsion stabilizer, and film former.
Cellulose is a homopolymer of D-glucose units connected by 1,4-β-glucosidic linkages.
The synthesis, or preparation, of hydroxyethylcellulose consists of treating cellulose with alkali followed by reaction with ethylene oxide.
As a result, the pendant hydroxyl groups are substituted with hydroxyethyl substituents to a degree that depends on the extent of the reaction.
As the degree of hydroxethyl substitution along the cellulose backbone increases, the biopolymer becomes more water soluble.
As indicated by the structural formula above, there are a number of posible structures that may evolve during the ethylene oxide substitution of cellulose.
For example, ethylene oxide can react at any of the three hydroxyl substituents on each anhydrous cellulose ring.
In addition, ethylene oxide may further react with ethylene oxide units that are already attached to the anhydrous cellulose ring.
The molar substitution (MS) of hydroxyethylcellulose is the average number of ethylene oxide units attached to the anhydrous cellulose ring while the degree of substitution (DS) is the average number of hydroxyl groups on the ring that have been substituted with ethylene oxide units.
Properties
Hydroxyethylcellulose is a biopolymer.
Therefore, many of its properties will depend on its molecular weight and the degree of substitution of hydroxyethyl or hydroxyl groups on the pyranose ring.
Solubility: water (soluble), alcohol (soluble up to 70 °C), and organic solvents (soluble).
Surface tension: 64 dynes/cm
Refractive index: 1.337
