Reference

Reference 1

Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study without detailed documentation

Qualifier:

equivalent or similar to guideline

Guideline:

ASTM D93 (Standard test methods for flash point by pensky-martens closed cup tester)

Deviations:

no

GLP compliance:

no

Type of method:

closed cup

Flash point apparatus:

Pensky-Martens apparatus

Specific details on test material used for the study:

The Cola®Teric CDB is a liquid material comprising 30% w/w active surfactant with about 6% w/w associated salt and 64% w/w water. The solution was measured “as is” for a single determination

Key result

Flash point:

> 75 °C

Remarks on result:

no flash point according to standard method

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Description of key information

The flash point for Cetyl Betaine; CAS# 693-33-4 was attempted using the Pensky–Martens closed-cup (PMCC) method. The substance shows no distinct flash up to 75°C, and therefore is nonflammable. Above 75°C moisture from the product extinguishes the flame.

This end point has been waived on the grounds that the substance is a solid even though it is normally supplied as an aqueous liquid. As an aqueous liquid, there is no possiblity of a flash under the conditions of the stanndard test.
