Test objective
The objective of the test is to determine the lowest temperature at which the test item produces vapour in a closed container and under conditions defined in the method, in such amounts that a flammable vapour/air mixture is formed. This temperature or flash point
is expressed in degrees Celsius.
Principle
The test item is placed in a container which is gradually heated until the concentration of the vapour in air is sufficiently high to produce a flammable mixture which could be ignited.
GLP compliance:
yes (incl. QA statement)
Type of method:
equilibrium method closed cup
Flash point apparatus:

Endpoint:
flash point of flammable liquids
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
weight of evidence
Justification for type of information:
REPORTING FORMAT FOR THE CATEGORY APPROACH
Registered substance (as identified in Section 1.1 identification) has similar chemical structure as the others members of the Category "Amino Acid Alkyl Amides, Sodium or
Potassium Salts" (the source chemicals).

The category “Amino Acid Alkyl Amides, Sodium or Potassium Salts” has been developed and evaluated to cover the assessment of the intrinsic properties of several similar
substances within the context of REACH Regulation. The Category includes sodium or potassium salts of amino acid alkyl amides, with a carbon chain length range of C6-C16 and an
aminoacidic pool of not selected aminoacids reflecting the natural distributions of aminoacids in various vegetables and cereals.


1. HYPOTHESIS FOR THE CATEGORY APPROACH (ENDPOINT LEVEL)
The Category has been built up considering the common chemical structure of its members. They are UVCB substances and they share the following features:
- they are salts of amino acid alkyl amides
- they are sodium or potassium salts
- the carbon chain length ranges between C6 and C16
- the carbon chain derives from cocoyl or lauroyl fatty acids
- the aminoacidic part of the molecules comes from a pool of aminoacids
- the aminoacids pool reflects the natural distributions of aminoacids in various vegetables and cereals.

Overall, the Category was formed on the hypothesis that substances sharing this common chemical structure can be considered analogues and can share intrinsic properties too. No
trends in properties is expected, except for those physicochemical properties depending on the carbon chain length.

2. CATEGORY APPROACH JUSTIFICATION
These substances share (i) eye damage and (ii) the absence of significant systemic toxicity.
Key result
Flash point:
>= 97 °C
Remarks on result:
other: Category members (Amino Acid Alkyl Amides, Sodium or Potassium Salts) are not expected to be flammable.
Remarks:
Category members (Amino Acid Alkyl Amides, Sodium or Potassium Salts) are not expected to be flammable.
Executive summary:

The category “Amino Acid Alkyl Amides, Sodium or Potassium Salts” was formed on the hypothesis that substances sharing common chemical structure can be considered analogues and can share intrinsic properties too.

Based on this assumption, this property may be assessed using available data  for the category members.

The category has been assessed for members characterized by:

- sodium or potassium salts

- the carbon chain length ranges between C6 and C16

- the aminoacids pool reflects the natural distributions of aminoacids in various vegetables and cereals.

Description of key information

Key value for chemical safety assessment

Additional information

Category members (Amino Acid Alkyl Amides, Sodium or Potassium Salts) are not expected to be flammable.

A collection of the flash-point values are available for category members. All found values are listed below.

EC number

Flash-point

S1 - EC: 918-984-3

97.0°C

S2 - EC: 927-837-2

No flash point up to 110.5 °C

 

Overall, since the flash point is an information relevant to assess the flammability of liquid substances and considering that the physical state of the interested substances (at room temperature), no further investigation is deemed to be needed to characterize this property.

The substance is not expected to be flammable.
