Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The kinematic viscosity of 3-hydroxy-1,1-dimethylbutyl peroxyneodecanoate at 20°C is determined as equal to 81 cSt, corresponding to a dynamic viscosity of 77 cP or 77 mPa.s.

Additional information

The kinematic viscosity of 3-hydroxy-1,1-dimethylbutyl peroxyneodecanoate at 20°C is determined as equal to 81 cSt, corresponding to a dynamic viscosity of 77 cP or 77 mPa.s.

The longer the storage time at 20°C, the more the viscosity decreases, due to thermal instability of the substance (SADT of the substance is 15°C).

When stored at -18°C (the storage temperature of the substance, available as 50% mixtures, is <-15°C), the viscosity is far higher.
