The purpose of this study was to determine the eye irritancy potential of Aspartic acid, N-(3-carboxy-1-oxo-sulfopropyl)-N-(C16-C18 (even numbered), C18unsaturated alkyl) tetrasodium salts by means of the chorioallantoic membrane of hens' eggs (HET-CAM). Eye irritation caused by external contact with chemical substances is characterized by corneal damage and/or conjunctival injury and/or iris defects.
The CAM of fertile eggs incubated for 9 days is a vital vascular membrane with a blood vessel complex.
Three eggs each were treated with 300 µL Aspartic acid, N-(3-carboxy-1-oxo-sulfopropyl)-N-(C16-C18 (even numbered), C18unsaturated alkyl) tetrasodium salts/egg and with the control items. 0.9% NaCl solution was used as the negative control item. 0.1 N Sodium hydroxide (NaOH) and 1% aqueous sodium dodecyl sulphate (SDS) were used as the positive control items. The administration volume for the control items was 300 µL per egg.
After administration of the test item blood vessels including the capillary system and the albumen were examined and scored for irritant effects (haemorrhage, coagulation and lysis) during 5 minutes.
The eggs treated with Aspartic acid, N-(3-carboxy-1-oxo-sulfopropyl)-N-(C16-C18 (even numbered), C18unsaturated alkyl) tetrasodium salts revealed aneffect with an irritation index (IS) of 10.0. The test item was considered to be a strong irritant.
The positive control items 0.1% NaOH or 1% SDS caused the expected effect with irritation indices (IS) of 18.3 or 10.0, respectively and, hence, were well within the historical data-range. No effects were observed in the negative control 0.9% NaCl solution. Hence,the HET-CAM assay is considered to be valid.

- Criteria used for interpretation of results: EU
- Conclusions:
- Under the present test conditions, Aspartic acid, N-(3-carboxy-1-oxo-sulfopropyl)-N-(C16-C18 (even numbered), C18unsaturated alkyl) tetrasodium salts was a strong irritant to eyes in an experiment employing the chorioallantoic membrane of hens' eggs (HET-CAM) as model.
