Thickening agent Wikipedia

2020-05-16· A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.. Thickeners may also improve the suspension of other ingredients or

2017-08-25· THICKENERS or PEG-200 Hydrogenated Glyceryl Palmate. These two types of thickeners provide two important differences in perfor-mance: the flow behaviour and the tem-perature dependence of the viscosity. 1. Flow behaviour The hydrophobic thickeners provide a shearthinningflowbehaviour,thatmeans the viscosity decreases with increasing shear rate.

Associative Thickeners for Viscosity Retention upon Tinting

For premium-class associative thickeners based on polyethyleneglycol, the hydrophobic caps are in most cases linked to the polyethyleneglycol by reaction with a diisocyanate to form a polyurethane. The products are therefore polyurethane thickeners, often called HEUR (hydrophobically modified ethoxylated urethane thickener) or just PU-thickeners.

Thickening Agent an overview ScienceDirect Topics

Unlike the natural thickeners, these associative thickeners are resistant to enzymatic or microbiological degradation. Careful formulation of associative thickeners with surfactants can provide enhancement of the rheology of aqueous detergent systems. 173–179 For nonionic surfactants, enhanced thickening is usually observed only for relatively hydrophobic surfactants.

2019-05-25· Two series of HASE APs were investigated: one in which the length of the hydrophobic alkyl chain was varied (C x E 35) and another in which the length of the PEO spacer arm was varied (C 20 E y). With increasing hydrophobe or PEO spacer arm length the average diffusion coefficient decreased, reflecting the viscosity enhancement produced by the associating network formed by

HEUR Thickeners Nonionic Polyurethane Associative

HEUR Thickeners impart high shear viscosity through the interaction of the thickener with hydrophobic surfaces within the coating formulation. Consequently, the main thickening mechanism of the HIRESOL HEUR thickeners is the association between the thickener and the binder/pigment colloid particles.
