Additional information
A reliable 96h LC50 value of 97 mg/L has been determined for the effects of hexan-1-ol (CAS 111-27-3) on mortality of the fish Pimephales promelas. This study represents the lowest measured reliable value available for this endpoint on hexan-1-ol.
Reliable short term toxicity to fish tests have determined the LC50 to lie in the range of 117 to 126 mg/L.
An estimated LC50 value has been predicted at 64 mg/L.
Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:
Linear LCAAs
The data summarised in the table below show that the toxicity of the single carbon number chain length LCAAs increases from an LC50 of 97 mg/L for C6 to 1.0 mg/L for C12. At higher carbon number chain lengths there is an absence of short-term toxicity (LC50 values are reported as being greater than the highest test concentration or higher than the water solubility of the test substance) and this is explained by the water solubility of an LCAA limiting its bioavailability, such that a toxic concentration for short-term exposure is not achieved.
The results of a 7-day, semi-static toxicity test with 1-octanol using Pimephales promelas larvae aged 1, 4 and 7 days at the start of the study have also been reported by (Pickering et al., 1996) but are not included in the table. NOECs based on nominal concentrations were 1.5-11.9 mg/L for survival. Measured concentrations in the test were reduced to non-detectable levels in most test vessels in the old media. The poor maintenance of exposure concentrations means that the reported NOEC values are almost certainly underestimates of the true toxicity of the substance. The results of this test are also discussed later with respect to long-term toxicity.
The lowest reliable LC50 values determined in tests with single carbon chain length LCAAs are shown in the following table.

Multi-constituent LCAAs
The data for multi-constituent substances of different carbon chain length LCAAs (commercial products) are shown in the table below. The results show that substances containing LCAAs with carbon numbers in the ranges of C8-10 and C6-12 exert short-term toxic effects at concentrations of between 0.7 and 10 mg/L. At these concentrations, all the constituents are likely to have been fully dissolved.
In contrast, multi-constituent substances - Alcohols, C12-13; Alcohols, C12-13-branched and linear and Alcohols, C12-15-branched and linear - exhibited effects at loading rates where not all constituents were fully dissolved. Under such circumstances the presence of retained undissolved test material, such as occurred in the Shell Toxicology Laboratory (1978a) test, opens up the possibility for physical fouling of the test organism and this needs to be kept in mind when interpreting the result. The multi-constituent substances containing LCAAs with carbon chain length C12 and above did not exhibit short-term toxicity effects at loading rates where the solubility of the constituent LCAAs was exceeded.
The data for nonanol, branched and linear, decanol branched and linear, decanol branched and undecanol branched alcohols, have been read-across from their linear alcohols counterparts (C9, C10 and C11) since they are essentially linear alcohols.
Alcohols, C14-15 ecotoxicity assessment is based on weight of evidence from two studies; Shell Internationale Chemie (1973) and Shell Toxicology Lab (1978a). Both studies report the LC50 to be above the limit of solubility. The Shell Internationale Chemie (1973) study tested the toxicity of the substance via the WAF preparation method (the preferred method of testing with poorly soluble mixtures) however it does not report complete information on the study methods and conditions. The Shell Toxicology Lab (1978a) did not utilise WAF methods but it is reported more comprehensively.
The results for both single carbon number LCAAs and the multi-constituent substances indicate that, for fish, there is a short-term toxicity cut-off for LCAAs with carbon numbers >C14.
The lowest reliable LC50 values determined in tests with multiconstituent carbon chain length LCAAs are shown in the following table.
