Results for,

 Test material  Test guideline  Flash point in °C
 Isomeren-Menthol, 76BA8  DIN EN 2719  88.0
 Rein-Menthol, 76KF3  DIN EN 2719  93.0
Roh-Menthol, 73BA4   DIN EN 2719  87.0

Rein-Menthol, 76KF3 corresponds to CAS 89 -78 -1

Interpretation of results:
GHS criteria not met
Executive summary:

The flash point of DL-Menthol (CAS no. 89-78-1) is 93 °C. The study was conducted according ISO 2719: 2002 (Determination of flash point - Pensky-Martens closed cup method) (Bayer Industry Services, 2006).

Description of key information

As DL-Menthol is handled as melt and the melting point is 43 °C, the flash point has been determined according to

ISO 2719: 2002 (Determination of flash point - Pensky-Martens closed cup method) (Bayer Industry Services, 2006). For DL-Menthol the flash point is 93 °C.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
93 °C

Additional information

Another study determined the flash point of raw Menthol, which consists of ca. 60 % DL-Menthol, as 90 °C (Currenta, 2010) according to EU Method A.9 (Flash-Point)(DIN EN ISO 2719).
