- 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
- Water solubility:
- ca. 395 mg/L
- Remarks on result:
- other: soluble in water
- Remarks:
- Category members (Amino Acid Alkyl Amides, Sodium or Potassium Salts) are soluble in water.
- Conclusions:
- A collection of the water solubility values is available for category members. Considering these values registered substance is considered soluble in water.
- 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.
