Storax balsamStorax (Latin: storax; Greek: στύραξ, stúrax), often commercially sold as styrax, is a natural fragrant resin isolated from the wounded bark of Liquidambar orientalis Mill. (Asia Minor) and Liquidambar styraciflua L. (Eastern US, Mexico, Central America) (Altingiaceae). It is distinct from benzoin (also called "storax"), a similar resin obtained from the Styracaceae plant family.
Cinnamic acidCinnamic acid is an organic compound with the formula C6H5−CH=CH−COOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants. It exists as both a cis and a trans isomer, although the latter is more common. The cis-isomer is called allocinnamic acid.Empirical formulaIn chemistry, the empirical formula of a chemical compound is the simplest whole number ratio of atoms present in a compound. For example, sulfur monoxide and disulfur dioxide, both compounds of sulfur and oxygen, both have the empirical formula SO. However, their molecular formulas, which express the number of atoms in each molecule of a chemical compound, are SO and S2O2, respectively. An empirical formula makes no mention of the arrangement or number of atoms.
LiquidambarLiquidambar, commonly called sweetgum (star gum in the UK), gum, redgum, satin-walnut, styrax or American storax, is the only extant genus in the flowering plant family Altingiaceae and has 15 species. They were formerly often treated as a part of the Hamamelidaceae. They are native to southeast and east Asia, the eastern Mediterranean and North America. They are decorative deciduous trees that are used in the wood industry and for ornamental purposes.

PolystyrenePolystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. By weight, it is considered a relatively cheap resin and a fairly poor barrier to oxygen and water vapor, with a relatively low melting point. Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year.
Organic compoundOrganic compounds are a subclass of chemical compounds of carbon. Little consensus exists among chemists on the exact definition of organic compound; the only universally accepted definition is the quasi-tautological "organic compounds are the subject matter of organic chemistry". Generally, any large chemical compound containing a carbon–hydrogen or carbon–carbon bond is accepted as an organic compound.
Chemical formulaCompact notation for chemical compounds A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts.
Vinyl groupIn organic chemistry, a vinyl group (abbr. Vi; IUPAC name: ethenyl group) is a functional group with the formula −CH=CH2. It is the ethylene (IUPAC name: ethene) molecule (H2C=CH2) with one fewer hydrogen atom. The name is also used for any compound containing that group, namely R−CH=CH2 where R is any other group of atoms. An industrially important example is vinyl chloride, precursor to PVC, a plastic commonly known as vinyl.
LiquidState of matter The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids. Liquid is a state of matter with a definite volume but no fixed shape. When confined in a container and subject to a force such as gravity, liquids will adapt to the internal shape of the container in the direction of the force. Liquids are nearly incompressible, maintaining their volume even under pressure.SubstituentIn organic chemistry, a substituent is one or a group of atoms that replaces (one or more) atoms, thereby becoming a moiety in the resultant (new) molecule. The suffix -yl is used when naming organic compounds that contain a single bond replacing one hydrogen; -ylidene and -ylidyne are used with double bonds and triple bonds, respectively.*As an Amazon Associate I earn from qualifying purchases.
