Cyclododecane
Encyclopedia
Cyclododecane is an organic compound with the chemical formula
C12H24.
Cyclododecane is mainly used as an intermediate in production of flame retardant
s, detergent
s, and other chemicals.
Cyclododecane is also used as a volatile binding medium, a temporary binder
for sealing and conservation of friable and structurally weak materials, e.g. during excavation and transport of archaeological
objects and in art restoration
, e.g. to protect water-sensitive parts during cleaning. Due to its relatively slow evaporation in comparison with other volatile binding mediums the layer can last for several weeks. Very pure material has to be used so it does not leave any residue. Cyclododecane can be applied in molten state or dissolved in a nonpolar organic solvent. Other volatile binding mediums in use are camphene
, tricyclene and with some limits menthol

Cyclododecane is highly volatile. It is persistent in the environment, as it does not biodegrade easily and does not under go hydrolysis
. Cyclododecane is lipophilic
, usually present in the environment as adsorbed on the surface of soil particles. Due to its tendency to persist in adipose tissue
it has a very high potential to bioaccumulate.http://www.coastalwiki.org/coastalwiki/Cyclododecane

Flame retardant
Flame retardants are chemicals used in thermoplastics, thermosets, textiles and coatings that inhibit or resist the spread of fire. These can be separated into several different classes of chemicals:...

Detergent
A detergent is a surfactant or a mixture of surfactants with "cleaning properties in dilute solutions." In common usage, "detergent" refers to alkylbenzenesulfonates, a family of compounds that are similar to soap but are less affected by hard water...

Art restoration
Art restoration is related to art conservation. Restoration is a process that attempts to return the work of art to some previous state that the restorer imagines was the "original". This was commonly done in the past...

Camphene
Camphene is bicyclic monoterpene. It is nearly insoluble in water, but very soluble in common organic solvents. It volatilizes readily at room temperature and has a pungent smell. It is a minor constituent of many essential oils such as turpentine, cypress oil, camphor oil, citronella oil,...

Menthol
Menthol is an organic compound made synthetically or obtained from peppermint or other mint oils. It is a waxy, crystalline substance, clear or white in color, which is solid at room temperature and melts slightly above. The main form of menthol occurring in nature is -menthol, which is assigned...

Lipophilic
Lipophilicity, , refers to the ability of a chemical compound to dissolve in fats, oils, lipids, and non-polar solvents such as hexane or toluene. These non-polar solvents are themselves lipophilic — the axiom that like dissolves like generally holds true...

In histology, adipose tissue or body fat or fat depot or just fat is loose connective tissue composed of adipocytes. It is technically composed of roughly only 80% fat; fat in its solitary state exists in the liver and muscles. Adipose tissue is derived from lipoblasts...
