Conclusion on classification

Justification for classification

According to Article 13 of Regulation (EC) No. 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", Information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (read-across approach), provided that conditions set out in Annex XI are met.

Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances… This avoids the need to test every substance for every endpoint”.

Since the category concept is applied to the polyol esters, data gaps will be filled by interpolation, as part of a read across approach from a representative category member(s) to avoid unnecessary animal testing. Additionally, once the category concept is applied, substances will be classified and labelled on this basis.

Brief description of the data relevant for classification

Degradation

Biodegradation:                    readily biodegradable: 95.6% of CO2 evolution (OECD 301 B); read-across

Bioaccumulation

Expert statement:                  Bioaccumulation is expected to be low.

Aquatic acute toxicity

For fish:                                96 h, LC50 (Brachydanio rerio): no effects up to the limit of water solubility (< 0.05 mg/L, purified water); read-across

For aquatic invertebrates:      48 h, EL50 (Daphnia magna): no effects up to the limit of water solubility (< 0.05 mg/L, purified water); read-across

For algae/aquatic plants:        72 h, ErL50 (Desmodesmus subspicatus): no effects up to the limit of water solubility (< 0.05 mg/L, purified water); read-across

Aquatic chronic toxicity

For fish:                                 no data available

For aquatic invertebrates:       21 d, NOELR (Daphnia magna): >= 1 mg/L, read-across

For algae/aquatic plant:          72 h, NOErLR (Desmodesmus subspicatus): no effects up to the limit of water solubility (< 0.05 mg/L, purified water); read-across

Conclusion on classification

CLP:

Based on the data above, Fatty acids C14-18 and C16-18 unsatd, esters with neopentyl glycol (CAS No. 85116 -81 -0) is considered to be rapidly degradable. The acute aquatic toxicity L(E)C(L)50 values are above the water solubility limit for fish, invertebrates and algae. Therefore, Fatty acids C14-18 and C16-18 unsatd, esters with neopentyl glycol does not meet the criteria for classification and labelling as acute aquatic hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).

Valid chronic toxicity data are available - the NOEC is above the water solubility limit. Therefore, Fatty acids C14-18 and C16-18 unsatd, esters with neopentyl glycol does not meet the criteria for classification and labelling as long-term aquatic hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).

DSD:

The acute aquatic toxicity L(E)C50 values are > 100 mg/L or above the water solubility limit for fish, invertebrates and algae. Therefore, Fatty acids C14-18 and C16-18 unsatd, esters with neopentyl glycol does not meet the criteria for classification and labelling as environmental hazard according to Directive 67/548/EEC.
