Reference
Endpoint:
thermal stability
Type of information:
experimental study
Adequacy of study:
key study
Study period:
05-11-2016- 06-02-2017 (misprint says 06-02-2016)
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Remarks:
Guidelines not mentioned, but similar to requirements of OECD 113 (Screening Test for Tbhermal Stability)
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 113 (Screening Test for Thermal Stability and Stability in Air)
Deviations:
not specified
Principles of method if other than guideline:
Determine transitions in Santicizer P1700 (VSC1002-2)
Method: -50C to 350C at 5K/minute in N2 at 50 mL/minute. TA Instruments DSC 2920 V2.6A
GLP compliance:
not specified
Test substance thermally stable:
no
Key result
Operating temp.:
>= -50 °C
Key result
Operating temp.:
<= 350 °C
Sublimation:
no
Transformation products:
not measured
Conclusions:
P1700 did not exhibit any glass transition or melting transitions at between temperatures of -50°C to 192°C. The deflection at -4°C is due to the baseline. An exotherm is present at 193°C and the source of this exotherm is unknown. The sample starts to decompose at 317°C with a maximum decomposition rate occurring at 341°C.
Executive summary:

P1700 did not exhibit any glass transition or melting transitions at between temperatures of -50°C to 192°C. The deflection at -4°C is due to the baseline. An exotherm is present at 193°C and the source of this exotherm is unknown. The sample starts to decompose at 317°C with a maximum decomposition rate occurring at 341°C.

Description of key information

In an analysis performed following OECD 113 (thermal stability- although the specific guideline is not mentioned in the internal report): P1700 did not exhibit any glass transition or melting transitions at between temperatures of -50°C to 192°C. The deflection at -4°C is due to the baseline. An exotherm is present at 193°C and the source of this exotherm is unknown. The sample starts to decompose at 317°C with a maximum decomposition rate occurring at 341°C.
