Storage room temperature 20 ± 5°C, dark - Analytical method:
- high-performance liquid chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- ca. -0.69
- Temp.:
- 20.2 °C
- pH:
- 5.9
- Details on results:
- The average n-octanol/water partition coefficient of the test item at 20.2°C and at pH5.9 is Pow= 2.38E-01
The standard deviation of all tabulated individual determination is: +/- 1.39E-01
The non-repeatability of the different partition coefficient is due to the presence of a third phase (localized between the aqueous phase and the octanol phase). Indeed, the test item is surface-acting and so it was complicated to analyze it properly. - Conclusions:
- The value of n-octanol/water partition coefficient found in this study is: Pow= 2.38E-01 and Log(Pow)= -0.69 at 20.2°C in purified water (pH 5.9)
- Executive summary:
The Log P of the test item is equal to -0.69.

- Objective of the test:
The objective of the test was to determine the partition coefficient of LCE07102 by calculation.
Principle:
The partition coefficient is defined as the ratio of the equilibrium concentrations of the test substance in a two-phase system consisting of two largely immiscible solvents. n-Octanol and water are generaly used:
Pow = Cn-octanol / Cwater
The partition coefficient (Pow) therefore is the quotient of two concentrations and is usually given in the form of its logarithm to base 10 (log Pow).
The methods given in the Commission Directive 92/69/EEC - A8 method (1992) are not usable when the substance shows tension-active properties.
The partition coefficient can then be obtained by calculation. The obtained value is a trend of the value of the partition coefficient. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- calculation method (fragments)
- Partition coefficient type:
- octanol-water

- 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
- Type:
- log Pow
- Remarks on result:
- not measured/tested
- Remarks:
- equal to -0.69 according to OECD Guideline 107 (Partition Coefficient (n-octanol/water), Shake Flask Method).
- Conclusions:
- Beacuse the shake-flask method applies only to essentially pure substances soluble in water and n-octanol. It is not applicable to surface active materials as the interest substance (for which a calculated value or an estimate based on the individual n-octanol and water solubilities is provided).
A collection of the predicted partition coefficient n-octanol/water values is available for category members. Considering these predicted values, for the registered substance the partition coefficient n-octanol/water is equal to -0.69 according to OECD Guideline 107 (Partition Coefficient (n-octanol/water), Shake Flask Method). - 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.
