The available in vivo repeated dose data on this endpoint is consistent within the group. The endpoint data covers the smallest (shortest alky chain, lowest number of amine and carboxymethylated groups, CAS no 2098351-38-1) as well as the biggest structure (longest alkyl-unsaturated chain, highest number of amine and carboxymethylated groups, CAS no 2060541-49-1) within the amphoteric, glycinate group. Both the substances have been recently tested according to the OECD 422 Guidance document under GLP. In the two studies no adverse parental effects were seen in any of the doses tested.

The NOAEL values from these two studies are comparable and are based on the highest dose tested. For Coco iminodiglycinate, (Amines, N-C12-18-alkyltrimethylenedi-, reaction products with chloroacetic acid, sodium salts with CAS no 2098351-38-1 the NOAEL is 675.50 mg a.i./kg bw/day and for Sodium oleylamphopolycarboxyglycinate, (1,3 -Propanediamine, N1 -(3 -aminopropyl)-N3 -[3 -[(9Z)-9 -octadecen-1 -ylamino]propyl]-, N-(carboxymethyl) derivs., sodium salts with CAS no 2060541 -49 -1) the NOAEL is 1000 mg a.i./kg bw/day.

Based on structural similarity, the NOAEL of Coco iminodiglycinate, (Amines, N-C12-18-alkyltrimethylenedi-, reaction products with chloroacetic acid, sodium salts with CAS no 2098351-38-1), which is based on a short chain (mainly C12-18) diamine substance, is used for read across to the Sodium cocoamphopolycarboxyglycinate, which is a triamine based substance with the same short alkyl chain (mainly C12-C18). The same approach is used for the NOAEL of Sodium oleylamphopolycarboxyglycinate, (1,3 -Propanediamine, N1 -(3 -aminopropyl)-N3 -[3 -[(9Z)-9 -octadecen-1 -ylamino]propyl]-, N-(carboxymethyl) derivs., sodium salts with CAS no 2060541 -49 -1), which is a tetramine with predominantly longer (C18:1) alkyl chains. Read across is applied to the other tetramine based substance Sodium tallowamphopolycarboxyglycinate (Amines, N-[3-[(3-aminopropyl)amino]propyl]-Nā€™-(C16-18 and C18-unsatd. alkyl)trimethylenedi-, N-(carboxymethyl) derivs., sodium salts with CAS no 2060541-47-9), which has slightly shorter alkyl chains (C16-18, C18:1). These NOAEL values have been used for the derivation of the relevant DNEL values used in each of the risk assessment for the different amphoteric, glycinate substances.
