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.
Chemical Thickeners. Thickeners, or "rheology modifiers," are generally some type of . For water-based paints, there are a wide variety of thickeners, all of which give the paint different properties.
Methyl cellulose or methylcellulose is a chemical compound derived from cellulose. It is sold under a variety of trade names and is used as a thickener and emulsifier in various food and cosmetic products, and also as a bulk-forming laxative. Like cellulose, it is not digestible, not toxic, and not an allergen.
In cooking a ﬁlling, about 1.5 kg 3 1/3 lb. of sugar should be cooked with the water or juice for every 500 g 18 oz. of starch used as a thickener. Approximately 100 g 4 oz. of starch is used to thicken 1 L of water or fruit juice. The higher the acidity of the fruit juice, the more thickener required to hold the gel.
Comperlan KD is a yellow liquid-solid used as a thickener in surfactant preparations due to its viscosity-increasing properties. Comperlan KD has a pH value 1% of 8-10, an ester content of max. 6%, and a water content of max. 0.5%.
Physical Properties of Thickener 1422 or Acetylated Distarch Adipate . There are specific properties of acetylated distarch adipate or Thickener 1422 E1422 that make it distinct. This bulking agent is an odorless powder that appears white or light yellow.
Examples of thickening agents include: polysaccharides starches, vegetable gums, and pectin , proteins eggs, collagen, gelatin, blood albumin and fats butter, oil and lards . All purpose flour is the most popular food thickener, followed by cornstarch and arrowroot or tapioca. All of these thickeners are based on starch as the thickening agent.
Properties such as flow and leveling of a paint layer are greatly determined by the viscosity in the low and mid shear range, typically in the range between 0.01 and 1 sec -1. The thickening properties of polyurethane thickeners in this range are much weaker than, for instance, the thickening effect of cellulosics.
