Toluene, also known as toluol, is a substituted aromatic hydrocarbon with the chemical formula C6H5CH3, often abbreviated as PhCH3, where Ph stands for phenyl group. It is a colorless, water-insoluble liquid with the odor associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group by a single bond. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent.
In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses mainly on naturally occurring resins.
Perfume is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. Perfumes can be defined as substances that emit and diffuse a pleasant and fragrant odor. They consist of manmade mixtures of aromatic chemicals and essential oils. The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory."
Balsam is the resinous exudate which forms on certain kinds of trees and shrubs. Balsam owes its name to the biblical Balm of Gilead.
Benzyl alcohol (also known as α-cresol) is an aromatic alcohol with the formula C6H5CH2OH. The benzyl group is often abbreviated "Bn" (not to be confused with "Bz" which is used for benzoyl), thus benzyl alcohol is denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor. It is a useful as a solvent for its polarity, low toxicity, and low vapor pressure. Benzyl alcohol has moderate solubility in water (4 g/100 mL) and is miscible in alcohols and diethyl ether. The anion produced by deprotonation of the alcohol group is known as benzylate or benzyloxide.
Benzoin or benjamin is a balsamic resin obtained from the bark of several species of trees in the genus Styrax. It is used in perfumes and some kinds of incense and as a flavoring and medicine. It is distinct from the chemical compound benzoin, which is ultimately derived chemically from benzoin resin; the primary active ingredient of benzoin resin is actually benzoic acid, not benzoin.
Oleoresins are semi-solid extracts composed of resin and essential or fatty oil, obtained by evaporation of the solvents used for their production. The oleoresin of conifers is known as crude turpentine or gum turpentine, which consists of oil of turpentine and rosin.
A fixative is a substance used to equalize the vapor pressures, and thus the volatilities, of the raw materials in a perfume oil, and to increase the perfume's odour tenacity.
Storax, often commercially sold as styrax, is a natural resin isolated from the wounded bark of Liquidambar orientalis Mill. and Liquidambar styraciflua L. (Hamamelidaceae). It is distinct from benzoin, a similar resin obtained from the Styracaceae plant family.
Myroxylon is a genus of Fabaceae native to Latin America.
Benzyl benzoate is an organic compound which is used as a medication and insect repellent. As a medication it is used to treat scabies and lice. For scabies either permethrin or malathion is typically preferred. It is applied to the skin as a lotion. Typically two to three applications are needed. It is also present in Balsam of Peru, Tolu balsam, and in a number of flowers.
Benzyl chloride, or α-chlorotoluene, is an organic compound with the formula C6H5CH2Cl. This colorless liquid is a reactive organochlorine compound that is a widely used chemical building block.
Copaiba is an oleoresin obtained from the trunk of several pinnate-leaved South American leguminous trees. The thick, transparent exudate varies in color from light gold to dark brown, depending on the ratio of resin to essential oil. Copaiba is used in making varnishes and lacquers.
Balsam of Peru or Peru balsam, also known and marketed by many other names, is a balsam derived from a tree known as Myroxylon balsamum var. pereirae; it is found in El Salvador, where it is an endemic species.
Stacte and nataph are names used for one component of the Solomon's Temple incense, the Ketoret, specified in the Book of Exodus. Variously translated to the Greek term or to an unspecified "gum resin" or similar, it was to be mixed in equal parts with onycha, galbanum and mixed with pure frankincense and they were to "beat some of it very small" for burning on the altar of the tabernacle.
Benzyl cinnamate is the chemical compound which is the ester derived from cinnamic acid and benzyl alcohol.
Opopanax is the commercial name of bisabol or bissabol, the fragrant oleo-gum-resin of Commiphora guidottii. It has been a major export article from Somalia since ancient times, and is called hebbakhade, habaghadi or habak hadi in Somali. It is an important ingredient in perfumery and therefore known as scented myrrh, sweet myrrh, perfumed myrrh or perfumed bdellium.
Resinoids are extracts of resinous plant exudates.
Myroxylon balsamum, Santos mahogany, is a species of tree in the family Fabaceae. It is native to tropical forests from Southern Mexico through the Amazon regions of Peru and Brazil at elevations of 200–690 metres (660–2,260 ft). Plants are found growing in well drained soil in evergreen humid forest.
