Hydroxyethyl Cellulose

	Hydroxyethyl Cellulose Hydroxyethyl cellulose is a gelling and thickening agent derived from cellulose. It is widely used in cosmetics, cleaning solutions, and other household products. Hydroxyethyl cellulose and methyl cellulose are frequently used with hydrophobic drugs in capsule formulations, to improve the drugs' dissolution in the gastrointestinal fluids. This process is known as hydrophilization. Hydroxyethyl cellulose is also used extensively in the oil & gas industry as a drilling mud additive under the name HEC as well in industrial applications, paint & coatings, ceramics, adhesives, emulsion polymerization, inks, construction, welding rods, pencils and joint fillers. Hydroxyethyl cellulose can be one of the main ingredients in water-based personal lubricants. It is also a key ingredient in the formation of big bubbles as it possesses the ability to dissolve in water but also provide structural strength to the soap bubble. Among other similar chemicals, it is often used as slime Slime m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Cellulose Cellulose is an organic compound with the formula , a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Cellulose for industrial use is mainly obtained from wood pulp and cotton. Some animals, particularly ruminants and termites, can digest cellulose with the help of ...

	Methyl Cellulose Methyl cellulose (or methylcellulose) is a 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 2020, it was the 422nd most commonly prescribed medication in the United States, with more than 100thousand prescriptions. Uses Methyl cellulose has a wide range of uses. Medical Constipation Methyl cellulose 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.

	Hydrophilization Hydrophilization is a process used for hydrophobic drugs to increase their release rate from capsules, which is dependent on the rate of dissolution, by covering the surface of the drug particles with minute droplets of a hydrophilic polymer solution. Method The process is accomplished by vigorous mixing of the hydrophobic drug with the aqueous solution of the hydrophilic polymer solution, leading to production of small particles of the drug covered with small droplets of the hydrophilic polymer solution. Uses This process in tablet or capsule formulations enhance the disintegration of the drug/excipient bulk and so enhance the rate of dissolution of the hydrophobic drug. Examples of the hydrophilic polymers are methyl cellulose and hydroxyethyl cellulose Hydroxyethyl cellulose is a gelling and thickening agent derived from cellulose. It is widely used in cosmetics, cleaning solutions, and other household products. Hydroxyethyl cellulose and methyl cellulose are frequently used ...

picture info	Personal Lubricants Personal lubricants (colloquially termed lube) are specialized lubricants used during sexual acts, such as intercourse and masturbation, to reduce friction to or between the penis and vagina, anus or other body parts or applied to sex toys to reduce friction or to ease penetration. Surgical or medical lubricants or gels, which are similar to personal lubricants but not usually referred to or labelled as "personal" lubricants, may be used for medical purposes such as speculum insertion or introduction of a catheter. The primary difference between personal and surgical lubricants is that surgical lubricants are thicker, sterile gels, typically containing a bacteriostatic agent. As of 2015 the personal lubricant market was estimated to be worth at least $400 million. Types By composition Water-based Water-based personal lubricants are water-soluble and are the most widely used personal lubricants. The earliest water-based lubricants were cellulose ether or glycerin solutions. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Dissolution (chemistry) Solvation (or dissolution) describes the interaction of a solvent with dissolved molecules. Both ionized and uncharged molecules interact strongly with a solvent, and the strength and nature of this interaction influence many properties of the solute, including solubility, reactivity, and color, as well as influencing the properties of the solvent such as its viscosity and density. If the attractive forces between the solvent and solute particles are greater than the attractive forces holding the solute particles together, the solvent particles pull the solute particles apart and surround them. The surrounded solute particles then move away from the solid solute and out into the solution. Ions are surrounded by a concentric shell of solvent. Solvation is the process of reorganizing solvent and solute molecules into solvation complexes and involves bond formation, hydrogen bonding, and van der Waals forces. Solvation of a solute by water is called hydration. Solubility of solid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Soap Bubble A soap bubble is an extremely thin film of soap or detergent and water enclosing air that forms a hollow sphere with an iridescent surface. Soap bubbles usually last for only a few seconds before bursting, either on their own or on contact with another object. They are often used for children's enjoyment, but they are also used in artistic performances. Assembling many bubbles results in foam. When light shines onto a bubble it appears to change colour. Unlike those seen in a rainbow, which arise from differential refraction, the colours seen in a soap bubble arise from light wave interference, reflecting off the front and back surfaces of the thin soap film. Depending on the thickness of the film, different colours interfere constructively and destructively. Mathematics Soap bubbles are physical examples of the complex mathematical problem of minimal surface. They will assume the shape of least surface area possible containing a given volume. A true minimal surface is more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Gunge Gunge as it is known in the United Kingdom, or slime as it is known in the United States and most English-speaking areas of the world, is a thick, gooey, yet runny substance with a consistency somewhere between that of paint and custard. It has been a feature on many children's programs for many years around the world and has made appearances in game shows as well as other programming. While gunge mostly appears on television, it can also be used as a fundraising tool for charities, youth and religious groups. Gunge tanks have appeared at nightclubs and Fun Days. The British charities Comic Relief and Children in Need, supported by the BBC, have used gunge for fundraising in the past. In the U.S., slime is sometimes associated with Nickelodeon, even having several game shows revolving around it, such as ''Slime Time Live''. It is also a key aspect of WAM or Sploshing Fetish.
