Menthoxypropanediol
Menthoxypropanediol (also known as Cooling agent 10 radename of Takasago, is a synthetic derivative of menthol. While the cooling strength of 3-(l-menthoxy)propane-1,2-diol is accepted as being about 20â25% that of menthol, it is also noted that "in a Vaseline Vaseline ()Also pronounced with the main stress on the last syllable . is an American brand of petroleum jelly-based products owned by transnational company Unilever.

It is used in various cosmetic chemical concoctions. References Flavors Cooling flavors Analgesics Monoterpenes Vicinal diols Isopropyl compounds {{organic-compound-stub ...

Menthol
Menthol is an organic compound, more specifically a monoterpenoid, made synthetically or obtained from the oils of corn mint, peppermint, or other mints. It is a waxy, clear or white crystalline substance, which is solid at room temperature and melts slightly above. The main form of menthol occurring in nature is (â)-menthol, which is assigned the (1''R'',2''S'',5''R'') configuration. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. Menthol also acts as a weak Îș-opioid receptor agonist. Structure Natural menthol exists as one pure stereoisomer, nearly always the (1''R'',2''S'',5''R'') form (bottom left corner of the diagram below). The eight possible stereoisomers are: : In the natural compound, the isopropyl group is in the ''trans'' orientation to both the methyl and hydroxyl groups. Thus, it can be drawn in any of the ways shown: : The (+)- and (â)-enantiomers of menthol are the most stable among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaseline
Vaseline ()Also pronounced with the main stress on the last syllable . is an American brand of petroleum jelly-based products owned by transnational company Unilever. Products include plain petroleum jelly and a selection of skin creams, soaps, lotions, cleansers, and deodorants. In many languages, the word "Vaseline" is used as generic for petroleum jelly; in Portugal, the Unilever products are called Vaselina, and in Brazil and some Spanish-speaking countries, the Unilever products are called Vasenol. History In 1859, Robert Chesebrough, a chemist who formerly clarified kerosene from the oil of sperm whales, traveled to the oil fields in Titusville, Pennsylvania to research what new materials might be created from this new fuel. There he learned of a residue called rod wax that had to be periodically removed from oil rig pumps. The oil workers had been using the substance to heal cuts and burns. Chesebrough took samples of the rod wax back to Brooklyn, extracted the us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavors
Flavor or flavour is either the sensory perception of taste or smell, or a flavoring in food that produces such perception. Flavor or flavour may also refer to: Science *Flavors (programming language), an early object-oriented extension to Lisp * Flavour (particle physics), a quantum number of elementary particles related to their weak interactions *Flavor of Linux, another term for any particular Linux distribution; by extension, "flavor" can be applied to any program or other computer code that exists in more than one current variant at the same time Film and TV * ''Flavors'' (film), romantic comedy concerning Asian-Indian immigrants in America Music Artists and bands *Flavor Flav (born 1959), former rap/hip-hop promoter and current reality television actor *Flavour N'abania (born 1983), Nigerian singer-songwriter * Flavor (band), minor hit with "Sally Had A Party" in 1968 Albums * ''Flavours'' (album), 1975 album by The Guess Who * ''Flavors'' (album), by American R&B ...

Cooling Flavors
Cooling is removal of heat, usually resulting in a lower temperature and/or phase change. Temperature lowering achieved by any other means may also be called cooling.ASHRAE Terminology, https://www.ashrae.org/technical-resources/free-resources/ashrae-terminology The transfer of thermal energy may occur via thermal radiation, heat conduction or convection. Examples can be as simple as reducing temperature of a coffee. Devices *Coolant *Cooling towers, as used in large industrial plants and power stations * Daytime passive radiative cooler *Evaporative cooler *Heat exchanger *Heat pipe *Heat sink * HVAC (Heating, Ventilation and Air Conditioning) * Intercooler *Radiative cooling in Heat shields * Radiators in automobiles *Pumpable ice technology *Thermoelectric cooling *Vortex tube The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analgesics
An analgesic drug, also called simply an analgesic (American English), analgaesic (British English), pain reliever, or painkiller, is any member of the group of drugs used to achieve relief from pain (that is, analgesia or pain management). It is typically used to induce cooperation with a medical procedure. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing to t ...

Monoterpenes
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C10H16. Monoterpenes may be linear (acyclic) or contain rings (monocyclic and bicyclic). Modified terpenes, such as those containing oxygen functionality or missing a methyl group, are called monoterpenoids. Monoterpenes and monoterpenoids are diverse. They have relevance to the pharmaceutical, cosmetic, agricultural, and food industries. Biosynthesis Monoterpenes are derived biosynthetically from units of isopentenyl pyrophosphate, which is formed from acetyl-CoA via the intermediacy of mevalonic acid in the HMG-CoA reductase pathway. An alternative, unrelated biosynthesis pathway of IPP is known in some bacterial groups and the plastids of plants, the so-called MEP-(2-methyl-D-erythritol-4-phosphate) pathway, which is initiated from Pentose, C5 sugars. In both pathways, IPP is isomerized to DMAPP by the enzyme isopentenyl pyrophosphate isomerase. Geranyl pyrophosphate is the pr ...
