Refined carrageenan has a 2% maximum for acid-insoluble material and is produced by alcohol precipitation or potassium chloride gel press process. [19] Semi-refined carrageenan has a much higher cellulose content [21] and is produced in a less complex process. Indonesia, the Philippines, and Chile are three main sources of raw material and ...
Potato starch slurry Roux. 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.
Carrageenan may prevent HPV and HSV transmission, but not HIV. See Carrageenan#Medical Uses. The phase III clinical trial for carrageenan-based Carraguard showed that it had no statistical effect on HIV infection, according to results released in 2008. The study showed that the gel was safe, with no side effects or increased risks.

Water gel explosives are produced by combining nitroparaffins, usually nitromethane, with an aqueous salt solution and a gelling agent. These nitroparaffins typically make up most of the water gel explosive. Different types of gelling agents are used to create the water gel explosive. One agent is insoluble in water, but able to gel with ...
At that point in the reaction, which is defined as gel point, the system loses fluidity and viscosity becomes very large. The onset of gelation, or gel point, is accompanied by a sudden increase in viscosity. [3] This "infinite" sized polymer is called the gel or network, which does not dissolve in the solvent, but can swell in it. [4]

Gellan gum is also used as gelling agent in plant cell culture on Petri dishes, as it provides a very clear gel, facilitating light microscopical analyses of the cells and tissues. Although advertised as being inert , experiments with the moss Physcomitrella patens have shown that choice of the gelling agent— agar or Gelrite—does influence ...
