RESUMO
In the present work, we assessed the relationship between alkyl carbon chain length and ocular irritation potentials using the hen's egg test-chorioallantoic membrane (HET-CAM) and bovine corneal opacity and permeability (BCOP) assays using 5 commercial alkyl polyglucoside surfactants with different compositions of alkyl chain lengths (C(6)-C(16)). With HET-CAM, there was a good correlation between the proportion of C(10) alkyl polyglucoside and the eye irritation potential Q score (r(2) = 0.912, p = .011). There were no significant differences between the proportion of C(10) alkyl polyglucoside and corneal opacity in BCOP assays; however, there was a relatively high positive correlation between the proportion of C(10) alkyl carbon chain lengths and corneal permeability (r(2) = 0.736, p = .063).
