Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to the ECHA Guidance for the implementation of REACH (“Guidance on information requirements and chemical safety assessment - Chapter R.7a: Endpoint specific guidance”; R.7.1.6 SURFACE TENSION, May 2008) for organic compounds, the surface tension study needs only be conducted if based on structure, surface activity is expected or can be predicted or surface activity is a desired property of the material. 
The substance, propylene glycol methyl ether acetate, is a low molecular weight organic compound which does not meet the definition of a surface active substance as it has no surface-active properties and does not consist of one or more hydrophilic and one or more hydrophobic groups of such a nature and size that it is capable of reducing the surface tension of water, and of forming spreading or adsorption monolayers at the water-air interface, and of forming emulsions and/or microemulsions and/or micelles, and of adsorption at water-solid interfaces.
In addition propylene glycol methyl ether acetate hydrolyzes in water to propylene glycol methyl ether and acetic acid. Propylene glycol methyl ether is known to be not a surface active substance.
The surface tension of neat propylene glycol methyl ether acetate was determined according to the Du Nouy method to be 29.4 mN/m at 20 °C and 29.0 mN/m at 25 °C.
