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

Remarks on result:

other: Absence of acute toxicity.

Remarks:

Category members (Amino Acid Alkyl Amides, Sodium or Potassium Salts) are deemed to be not acutely toxic.

Interpretation of results:

GHS criteria not met

Conclusions:

Category members (Amino Acid Alkyl Amides, Sodium or Potassium Salts) are deemed to be not acutely toxic.

A collection of the acute toxicity values is available for category members. Category members were investigated performed by means oral administration. All data support the absence of acute toxicity (LD50 oral rat > 2 000 mg/kg bw).

According to Regulation (EC) n. 1272/2008, the study results indicate that the registered substance should not be classified for acute oral toxicity because data are judged as "conclusive but not sufficient for classification".

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.

Examinations of the animals
Daily examination
Systematic examinations were carried out to identify any behavioural or toxic effects on the major
physiological functions 5 days after administration of the test solution.
This examination focuses particularly on a list of symptoms, recorded as "present" or "absent" on the
observation sheet.
These observations were compared to control data.
Observations and a mortality report were then carried out every day for 14 days.

Periodical examinations
The animals were weighed on day D0 (just before administering the test item) then on D2, D7, and
D14.
Weight changes were calculated and recorded.

Examination at the end of the test
On D14, the animals were anaesthetised with sodium pentobarbital and administration continued to
fatal levels. Macroscopic observations were entered on individual autopsy sheets.
Only those organs likely to be modified in cases of acute toxicity were examined. Those presenting
macroscopic anomalies can be removed and preserved in view to microscopic exanimations.
