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.
