Polynoxylin (trade name Anaflex in Egypt [1] ) is an antiseptic for local treatment of the skin and the mouth. It is a formaldehyde releasing antimicrobial polymer. [2]
In organic chemistry, an aldehyde is an organic compound containing a functional group with the structure R−CH=O. The functional group itself can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are common and play important roles in the technology and biological spheres.
Pentaerythritol is an organic compound with the formula C(CH2OH)4. Classified as a polyol, it is a white solid. Pentaerythritol is a building block for the synthesis and production of explosives, plastics, paints, appliances, cosmetics, and many other commercial products.
Formaldehyde is a naturally occurring organic compound with the formula CH2O and structure H−CHO. The pure compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde, hence it is stored as an aqueous solution (formalin), which is also used to store animal specimens. It is the simplest of the aldehydes. The common name of this substance comes from its similarity and relation to formic acid.
Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary in size but can range upwards of 64 by 8 feet and in the case of cross-laminated timber (CLT) can be of any thickness from a few inches to 16 inches (410 mm) or more. These products are engineered to precise design specifications, which are tested to meet national or international standards and provide uniformity and predictability in their structural performance. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products. The products can be used for joists and beams that replace steel in many building projects. The term mass timber describes a group of building materials that can replace concrete assemblies. Broad-base adoption of mass timber and their substitution for steel and concrete in new mid-rise construction projects over the coming decades could help mitigate climate change.
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibres but can be used as a building material similar in application to plywood. It is stronger and denser than particle board.
Cosmetology is the study and application of beauty treatment. Branches of specialty include hairstyling, skin care, cosmetics, manicures/pedicures, non-permanent hair removal such as waxing and sugaring, and permanent hair removal processes such as electrology and intense pulsed light (IPL).
666 is the natural number following 665 and preceding 667.
Quaternium-15 is a quaternary ammonium salt that has been used as a surfactant and preservative. It acts as an antimicrobial agent because it slowly releases formaldehyde, which is a preservative with biocidal properties.
Urea-formaldehyde (UF), also known as urea-methanal, so named for its common synthesis pathway and overall structure, is a nontransparent thermosetting resin or polymer. It is produced from urea and formaldehyde. These resins are used in adhesives, plywood, particle board, medium-density fibreboard (MDF), and molded objects. In agriculture, urea-formaldehyde compounds are one of the most commonly used types of slow-release fertilizer.
Paraformaldehyde (PFA) is the smallest polyoxymethylene, the polymerization product of formaldehyde with a typical degree of polymerization of 8–100 units. Paraformaldehyde commonly has a slight odor of formaldehyde due to decomposition. Paraformaldehyde is a poly-acetal.
Altretamine, also called hexamethylmelamine, is an antineoplastic agent. It was approved by the U.S. FDA in 1990.
Rongalite is a chemical compound with the molecular formula Na+HOCH2SO2−. This salt has many additional names, including Rongalit, sodium hydroxymethylsulfinate, sodium formaldehyde sulfoxylate, and Bruggolite. It is listed in the European Cosmetics Directive as sodium oxymethylene sulfoxylate (INCI). It is water-soluble and generally sold as the dihydrate. The compound and its derivatives are widely used in the dye industry. The structure of this salt has been confirmed by X-ray crystallography.
The number of the beast is associated with the Beast of Revelation in chapter 13, verse 18 of the Book of Revelation. In most manuscripts of the New Testament and in English translations of the Bible, the number of the beast is six hundred sixty-six or χξϛ. Papyrus 115, as well as other ancient sources like Codex Ephraemi Rescriptus, give the number of the beast as χιϛ or χιϲ, transliterable in Arabic numerals as 616, not 666; critical editions of the Greek text, such as the Novum Testamentum Graece, note χιϛ as a variant.
The Physical Impossibility of Death in the Mind of Someone Living is an artwork created in 1991 by Damien Hirst, an English artist and a leading member of the "Young British Artists". It consists of a preserved tiger shark submerged in formaldehyde in a glass-panel display case. It was originally commissioned in 1991 by Charles Saatchi, who sold it in 2004 to Steven A. Cohen for an undisclosed amount, widely reported to have been at least $8 million. However, the title of Don Thompson's book, The $12 Million Stuffed Shark: The Curious Economics of Contemporary Art, suggests a higher figure.
Methanediol, also known as formaldehyde monohydrate or methylene glycol, is an organic compound with chemical formula CH2(OH)2. It is the simplest geminal diol, and the simplest sugar alcohol. In aqueous solutions it coexists with oligomers. The compound is closely related and convertible to the industrially significant derivatives paraformaldehyde, formaldehyde, and 1,3,5-trioxane.
In enzymology, a 4-methoxybenzoate monooxygenase (O-demethylating) (EC 1.14.99.15) is an enzyme that catalyzes the chemical reaction
In enzymology, a mycothiol-dependent formaldehyde dehydrogenase (EC 1.1.1.306) is an enzyme that catalyzes the chemical reaction
A formaldehyde releaser, formaldehyde donor or formaldehyde-releasing preservative is a chemical compound that slowly releases formaldehyde. Formaldehyde-releasers are added to prevent microbial growth and extend shelf life. The intent of these compounds is that they release formaldehyde at levels that suppress microbial growth but sufficiently low to not threaten humans. The use of these chemicals in cosmetics has elicited controversy.
DMDM hydantoin is an antimicrobial formaldehyde releaser preservative with the trade name Glydant. DMDM hydantoin is an organic compound belonging to a class of compounds known as hydantoins. It is used in the cosmetics industry and found in products like shampoos, hair conditioners, hair gels, and skin care products.
Studio 666 is a 2022 American horror comedy film directed by BJ McDonnell from a screenplay by Jeff Buhler and Rebecca Hughes, based on a story by Dave Grohl. Grohl stars, alongside his Foo Fighters bandmates Nate Mendel, Pat Smear, Taylor Hawkins, Chris Shiflett, and Rami Jaffee.
