Additional information
A Skin Irritation study (Envigo Research Limited, 2018, study code FF02HX) was conducted to determine the skin irritation potential of Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts. The study was performed according to OECD test guideline 439 and EC method B46; the study was performed in compliance with GLP.
The effects of 15-minute dermal exposure followed by a post-exposure incubation period of 42 hours to Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts were investigated in EPISKIN reconstructed human epidermis model.
On the basis that test item did not directly reduce MTT, Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts was classified as non-irritant to skin.
A Skin Corrosion study (Envigo Research Limited, 2018, study code HF48BF) was conducted to determine the skin corrosion potential of Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts. The study was performed according to OECD test guideline 431 and EC method B.40bis; the study was performed in compliance with GLP.
The effects of 3-minute and 60-minute dermal exposure to Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts were investigated in EPISKIN reconstructed human epidermis model.
On the basis that test item did not directly reduce MTT, Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts was classified as non-corrosive to skin.
An Eye Irritation study (Envigo Research Limited, 2018, XD76KK) was conducted to assess the effect of the instillation of Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts into the eyes from adult cattle. The study was performed according to OECD test guideline 437 and EC method B47; the study was performed in compliance with GLP.
Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts (concentration 20% w/v in sodium chloride 0.9% w/v) was applied to three corneas for 240 minutes.
On vitro irritation score 66.2;
Permeability (OD) (mean permeability) score 2.903;
Cornea opacity score (mean corrected value) 22.7
Effects on skin irritation/corrosion: non-irritant/ non-corrosive to the skin
Effects on eye irritation: irritating (Category 1. UN GHS or EU CLP Causes serious eye damage)
Justification for classification or non-classification
The opacity and in Vitro Irritancy Score were found to be 22.7 and 66.2, respectively. In accordance with the Regulation (EC) 1272/2008 Appendix 1 (table 3.3.1), the substance will be classified as causing serious eye damage Category 1. The applicable hazard phrase is “H318: Causes serious eye damage”.
The substance was predicted to be non-corrosive and non-irritant to the skin; on this basis no classification for skin corrosion or irritation will be applied.
