A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. The edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste. The thickeners are also used in paints, inks, explosives, and cosmetics etc.
Thickeners may also improve the suspension of other ingredients or emulsions which increases the stability of the product. Thickening agents are often regulated as food additives and as cosmetics and personal hygiene product ingredients. Some thickening agents are gelling agents (gellants), forming a gel, dissolving in the liquid phase as a colloid mixture that forms a weakly cohesive internal structure. Others act as mechanical thixotropic additives with discrete particles adhering or interlocking to resist strain.
Thickening agents can also be used when a medical condition such as dysphagia causes difficulty in swallowing. Thickened liquids play a vital role in reducing risk of aspiration for dysphagia patients.
Thickener for Acrylic Paint Brands
One of the main use of thickeners is in the paint. The following are some of the best thickeners for acrylic paint brands which are easily available and worth – purchasing.
Cabosil Fumed Silica is the trade name for Fumed Silica, a ‘universal thickener’. Fumed silica (CAS number 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles.
The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler. Fumed silica and similar products form stiff microscopic chains or fibers which interlock or agglomerate into a mass, holding the associated liquid by surface tension, but which can separate or slide when sufficient force is applied.
• Fumed silica has a very strong thickening effect.
• The primary particle size is 5 – 50 nm.
• The particles are non – porous and have a surface area of 50 – 600 m2/g. The density is 160 – 190 kg/m3.
• Due to its fineness and thinness, fumed silica can easily become airborne.
• It is used as a light abrasive, in products like toothpaste.
• It is also used in the production of cat litter box filler and as a core material in the production of vacuum insulated panels.
• It will go in if you mix it in by hand but it will not develop its full effect if not well mixed.
One of our customers reported that it is used to thicken a polyester resin to peanut butter consistency and it works great. The user also shared a suggestion that one must make sure to use a gas mask as this is a very fine powder in order to remain safe from any sort of unnecessary trouble.
Marabu thickener is a water-based and it is ideal for thickening Marabu silk paints for painting, printing, stenciling or spatula application, as well as fine decorative work, texture painting and experimental work. The Marabu thickener contains sensitizing substance that may produce an allergic reaction.
• Acrylic Ver thicker farblos, dose with 225 ml

Liquitex offers a variety of speciality products including Fluid Mediums, Gel mediums, Texture Gels and Additives which have been specifically designed to achieve various techniques, applications and special effects. Liquitex Liquithick does not increase transparency. Liquitex Liquithick produces a matte surface sheen when dry. Paint and medium shrinkage will occur in proportion to the amount of Liquitex Liquithick added.
• It effects painting additive; a thickening gel for water soluble acrylic paint and acrylic mediums.
• It is of light weight, non-toxic and dries to a matte surface sheen.
• This includes 8 – oz / 237ml jar of medium.
• The Liquitex Liquithick thickening gel is intermixable with Liquitex Professional Acrylic Paint Colors and mediums.
• It is also confirmed that it is safe for educational use.
• They do not contain acrylic polymer emulsion.
The users were amazed after using this. They loved this stuff as they never heard of it until now. They further added that it works awesome turning acrylics paints into the consistency of oil paints.
Another feedback from our valuable customer reviewed that if one prefers Liquitex Liquithick Thickening Gel consistency, then don’t hesitate to get this product while ordering your paints. Thinning with water alone, even just a little bit, makes them runny.
In petrochemistry, gelling agents, also called solidifiers, are chemicals capable of reacting with oil spills and forming rubber-like solids. The gelled coagulated oil then can be removed from the water surface by skimming, suction devices, or nets. Calm or only moderately rough sea is required.
Various materials are used to convert liquid explosives to a gel form. Nitrocellulose and other nitro esters are often used. Other possibilities include nitrated guar gum.
Many fuels used in incendiary devices require thickening for increased performance. Aluminum salts of fatty acids are frequently used. Some formulations (e.g. Napalm-B) use polymeric thickeners, namely polystyrene. Hydroxyl aluminum (2-ethylhexanoate) is also used. Thickened pyrophoric agent, a pyrophoric replacement of napalm, is a triethylaluminium thickened with polyisobutylene.
