{{Definition|title=neodecanoic acid, ethenyl ester

|definition= Neodecanoic acid, ethenyl ester is an [[anthropogenic]] chemical used exclusively in polymerization to make products more hydrolytically and UV-stable. The primary uses include polymers used in paints and coatings (65%), and adhesives i.e. re-dispersible powders (35%)<ref name = OECD>[http://www.oecd.org/LongAbstract/0,3425,en_2649_34379_41825008_1_1_1_37407,00.html OECD Initial hazard assessment of Neodecanoic acid, ethenyl ester; CAS 5100-05-23; SIDS Initial Assessment Report For SIAM 24 Paris, France, 17 – 20 April 2007]</ref>.

Neodecanoic acid, ethenyl ester has a low risk of entering the environment. The production is carried out in a closed circuit with minimal releases to the environment. Only a very small amount (0,006%) of the neodecanoic acid, ethenyl ester used in paints and coatings can expected to be lost into the environment.
Its total global production volume ranges from 46,000 to 230,000 tonnes/yr<ref name = OECD>[http://www.oecd.org/LongAbstract/0,3425,en_2649_34379_41825008_1_1_1_37407,00.html OECD Initial hazard assessment of Neodecanoic acid, ethenyl ester; CAS 5100-05-23; SIDS Initial Assessment Report For SIAM 24 Paris, France, 17 – 20 April 2007]</ref>. 

Neodecanoic acid ethenyl ester is a light viscous liquid and is moderately [[volatile]]. Due to its low water solubility, it is suspected that in the environment it would be mostly associated with sediments. Only small amounts would be found in water and the atmosphere.  

It doesn't dissolve much in water and has a high affinity towards organic matter. However, it has only a moderate tendency towards [[bioaccumulation]]. There doesn't appear to be a risk for [[biomagnification]]. [[Pollution and pelagic fishes|Fish]] for example are able to eliminate neodecanoic acid ethenyl ester quite efficiently from their tissues (95% in 14 days)<ref name = OECD>[http://www.oecd.org/LongAbstract/0,3425,en_2649_34379_41825008_1_1_1_37407,00.html OECD Initial hazard assessment of Neodecanoic acid, ethenyl ester; CAS 5100-05-23; SIDS Initial Assessment Report For SIAM 24 Paris, France, 17 – 20 April 2007]</ref> .

Neodecanoic acid, ethenyl ester appears to be a very stable monomer that is not biodegradable, at least not by rats in vitro. It shows an high acute [[toxic|toxicity]] for fish and zooplankton and a lower one for algae: 0.84 mg/l, 0.3 mg/l and 3.4 mg/l respectively. Presently no studies have been conducted on chronic toxicity or sublethal effects.
In rats it has a low toxicity when inhaled, eaten or touched. It can also cause (minimal) irritation to their eyes and skin.  

The substance is considered to be of low risk towards human health, but might cause environmental problems (especially for fish and marine invertebrates) if released into the environment<ref name = OECD>[http://www.oecd.org/LongAbstract/0,3425,en_2649_34379_41825008_1_1_1_37407,00.html OECD Initial hazard assessment of Neodecanoic acid, ethenyl ester; CAS 5100-05-23; SIDS Initial Assessment Report For SIAM 24 Paris, France, 17 – 20 April 2007]</ref> .
