<unk>  has a wide range of uses. Medical Constipation<unk>  is used to treat constipation. Effects generally occur within three days. It is taken by mouth and is recommended with sufficient water. Side effects may include abdominal pain. It is classified as a bulk forming laxative. It works by increasing the amount of stool present which improves intestinal contractions. It is available over the counter. It is sold under the brand name Citrucel among others. Artificial tears and saliva The lubricating property of<unk>  is of particular benefit in the treatment of dry eyes. Solutions containing<unk>  or similar<unk>  derivatives are used as substitute for tears or saliva if the natural production of these fluids is disturbed. Medication manufacturing<unk>  is used in the manufacture of drug capsules; its edible and nontoxic properties provide a vegetarian alternative to the use of gelatin. Consumer products Thickener and emulsifier<unk>  is occasionally added to hair shampoos, tooth pastes and liquid soaps, to generate their characteristic thick consistency. This is also done for foods, for example ice cream or croquette.<unk>  is also an important emulsifier, preventing the separation of two mixed liquids because it is an emulsion stabilizer.<unk>  is also used as paint rheological modifier to prevent paint sagging. Food The E number of<unk>  as food additive is E461. E464 is hydroxypropylcellulose and more soluble in water.<unk> , as a gel, has the unique property of setting when hot and melting when cold.<unk>  is used as an ingredient in some meat analogues that are intended to replicate the texture of meat. Lubricant<unk>  may be used in personal lubricant. Construction materials<unk>  finds a major application as a performance additive in construction materials. It is added to mortar dry mixes to improve the mortar's properties such as workability, open and adjustment time, water retention, viscosity, adhesion to surfaces etc. Construction grade<unk>  is not to be identified with food and pharmaceutical grade<unk>  and hydroxypropyl<unk> , as it may be cross-linked with glyoxal for easy dispersion in water. The construction materials can be cement-based or gypsum-based. Notable examples of dry mixture mortars which utilize<unk>  include tile adhesives, EIFS, insulating plasters, hand-troweled and machine-sprayed plaster, stucco, self-leveling flooring, extruded cement panels, skim coats, joint & crack fillers, and tile grouts. Typical usage is about 0.2% – 0.5% of total dry powder weight for dry mixtures. Derivatives of<unk>  which improve performance characteristics include hydroxypropyl<unk>  (HPMC) and hydroxyethyl<unk>  (HEMC). These derivatives typically improve the characteristics such as water retention, vertical surface slip resistance, open time, etc. Glue and binder<unk>  can be employed as a mild glue which can be washed away with water. This may be used in the fixing of delicate pieces of art as well as in book conservation to loosen and clean off old glue from spines and bookboards.<unk>  is the main ingredient in many wallpaper pastes. It is also used as a binder in pastel crayons and also as a binder in medications. Hydroxypropyl<unk>  (HPMC) is an FDA-approved water-soluble adhesive, has been used in various wet-adhesion applications in construction products, paints, and drug delivery for 70 years.HPMC adheres strongly to all wet surfaces, regardless of hydrophobicity. Paper and textile sizing<unk>  is used as sizing in the production of papers and textiles as it protects the fibers from absorbing water or oil. Dust control Hydroxypropyl<unk>  (HPMC) and hydroxyethyl<unk>  (HEMC) is used as a binder in dust control technologies. They mitigate fugitive dust released from arid/semi-arid area as well as improve commercial face mask when used as a filtering material. Cell culture<unk>  is also used in cell culture to study viral replication. It is dissolved in the same nutrient-containing medium in which cells are normally grown. A single layer of cells is grown on a flat surface, then infected with a virus for a short time. The strength of the viral sample used will determine how many cells get infected during this time. The thick<unk>  medium is then added on top of the cells in place of normal liquid medium. As the viruses replicate in the infected cells, they are able to spread between cells whose membranes touch each other, but are trapped when they enter the<unk> . Only cells closely neighboring an infected cell will become infected and die. This leaves small regions of dead cells called plaques in a larger background of living uninfected cells. The number of plaques formed is determined by the strength of the original sample. Bacterial and protozoal motility inhibitor Aqueous<unk>  solutions have been used to slow bacterial and protozoal cell motility for closer inspection. Changing the amount of<unk>  in solution permits the adjustment of the solution's viscosity. Stem cell differentiation<unk>  is used in the most common approaches to quantify multiple or single lineage-committed hematopoietic progenitors, called colony-forming cells (CFCs) or colony-forming units (CFUs), in combination with culture supplements that promote their proliferation and differentiation, and allow the clonal progeny of a single progenitor cell to stay together and thus form a colony of more mature cells. Chemistry It is a hydrophilic white powder in pure form and dissolves in cold (but not in hot) water, forming a clear viscous solution or gel.<unk>  is used as a buffer additive in capillary electrophoresis to control electroosmotic flow for improved separations. Special effects The slimy, gooey appearance of an appropriate preparation of<unk>  with water, in addition to its nontoxic, nonallergenic, and edible properties, makes it popular for use in special effects for motion pictures and television wherever vile slimes must be simulated. In the film Ghostbusters, the gooey substance the supernatural entities used to "slime" the Ghostbusters was mostly a thick water solution of<unk> . The Aliens ooze and drip a great deal of<unk> —especially the queen.<unk>  has been used to safely simulate molten materials, as well. In several of the Terminator films, it was back-lit with colored gels and films to reproduce the heated glow of iron in the large pouring ladles used to transport the metal from the smelting ovens to the various molds and forms.<unk>  was also a stand-in for the lava flows in Los Angeles in Volcano and on the volcanic surface of Mustafar, in Star Wars: Episode III – Revenge of the Sith.
