Viscosity regulation

Fatty alcohol and fatty acid ethoxylates are amphiphilic compounds that are commonly used as nonionic surfactants and emulsifiers in many applications, such as cosmetic and care products and in textile fabrication. They serve as antistatic lubricants and viscosity regulators. 

MCC and carboxymethylcellulose sodium Avicel RC-581, RC-591, CL-611 FMC BioPolymer, Newark, Delaware, U.S.A. Viscosity regulator and modifier, thixotropic characteristics, heat and freeze-thaw stable, long shelf-life stability, lengthy hydration times eliminated, stable at pH range 4-11... 

Although cholesterol is essentially insoluble in water, a soluble cholesterol derivative can be formed by reacting it with high levels of ethylene oxide.66,67 This ethoxylated product has balanced hydrophobic and hydrophilic properties. The increased hydrophilicity makes it useful as an oil-inwater emulsifier or as a stabilizer. Ethoxylated lanolin is used for viscosity regulation, pigment dispersion, and as a solubilizer. Less than 1% ethoxylated cholesterol is effective at reducing the viscosity of anionic lotions to make them easier to pour. Non-ionic systems require more ethoxylated cholesterol for this purpose 68... 

The chemicals used for coating and laminating are polymeric materials, either naturally occurring or produced synthetically. These include natural and synthetic rubbers, polyvinyl chloride, polyvinyl alcohol, acrylic, phenohc resins, polyurethanes, silicones, fluorochemicals, epoxy resins and polyesters." Coating formulations typically include auxiliaries such as plasticizers, adhesion promoters, viscosity regulators, pigments, fillers, flame retardants, catalysts and the like. ... 

In addition to the traditional use in paints as viscosity regulator, bentonite is currently used in the development of new materials with nanocomposite structures. 

Fire resistance is an important property of phenolic resins. The combination of phenolic resin with Expancel expandable microspheres leads to many useful products. Composites for high speed train interiors take advantage of the light weight, excellent fire rating, and very low thermal conductivity. Polyester filled with aluminum hydroxide is an alternative solution for train interior materials. The resin and filler can be easily processed when viscosity regulating additives are added. 

Salts, generally sodium but also triethanolammonium, of long-chain alcohol sulfates and alcohol ether sulfates are the most widely used surfactants in shampoo formulations. Alkanolamides act as viscosity regulators and foam stabilizers.

The preparation of microcrystalline cellulose by acid hydrolysis of native and regenerated fibers has been studied extensively (3) and developed into a commercial process by Battista et ah (4). The resulting products are used as aqueous gels with high water-bonding capacity, inert food and drug additives, viscosity regulators, and stabilizers in colloidal... 

Aromatic and aliphatic hydrocarbons are used as extenders, particularly in the manufacture of PVC plastisols that must maintain as stable a viscosity as possible for relatively long periods of time (dip and rotational molding). The petroleum industry offers imprecisely defined products with an aliphatic-aromatic structure for use as extenders. They are added to plastisols in small amounts as viscosity regulators. Dibenzyl toluene also serves the same purpose. A disadvantage of this type of extenders is the risk of exudation if excessive quantities are used.

Poly (vinyl alcohol) (PVAL), Manufactured by saponification of poly(vinyl acetate). As a special water-soluble and organic-insoluble high-polymer, it is used as a viscosity regulating agent, as a thickener and/or protecting colloid in dispersions and adhesives. A starting material for the production of poly(vinyl acetals).
