Definition of cyclododecane:
Cyclododecane is a saturated, alicyclical hydrocarbon. [1]
This is the common definition for cyclododecane, other definitions can be discussed in the article

There are 2 main uses for cyclododecane: as an intermediate, e. g. for the production of flame retardants, cleaning and washing agents and other chemicals. It can also be used as a binding medium for temporarily sealing, consolidation and conservation of weak or friable materials in the field of excavation and transport of archaeological objects.[2]
It is very persistent in the environment. It's not hydrolysed abiotically and also not easily biodegraded. Considering that is highly lipofylic, cyclododecane it considered to be mostly adsorbed to particles and soils. It is also very volatile causing the dissolved cyclododecane to vaporize rapidly in the atmosphere. The concentrations of a small pond are halved in less than 4 hours due to evaporation. However, because of the effect of adhesion this takes 48 days. If released to the atmosphere, cyclododecane will abiotically be degraded. Cyclododecane has a very high potential to bioaccumulate, there is however no information available about its ability to biomagnify. Concentrations above 1 mg/l cause acute toxicity in fishes, concentrations above 2 mg/l toxicity in aquatic invertebrates. [2]
