TOXICOKINETIC BEHAVIOUR
Physico-chemical properties:
3-Lauramidopropyl trimethyl ammonium methyl sulphate (KEL3587) is a white waxy powder at room temperature and pressure and the molecular weight is 410.6 g/mol. The mean measured Log P (octanol-water) is </= -0.46 at 20 degC and the water solubility has been determined as >400g/L at 20 degC. The substance is miscible with water in any proportion. With increasing amount of test item a gel is formed. The pH value was 4.1.
The vapour pressure value is 2.1x10 -1 Pa at 20 degC which is indicative that the substance is not volatile at room temperature and pressure, therefore inhalation exposures are not a concern.
Absorption:
There are no directly measured ADME data by any route for 3-Lauramidopropyl trimethyl ammonium methyl sulphate.
Oral: In the key study for acute oral toxicity (Meisel, 1983), and the two repeat dose 90 days studies, there are no reported systemic effects and no indication of the extent of absorption when the substance was dosed by gavage in water. There is some limited evidence of potential systemic absorption from an earlier study by Fogleman (1963). Diarrhoea was the only clinical sign reported but mortality was observed in animals dosed orally in a 20% aqueous dispersion in 0.2% agar and 0.1% tween 80. The LD50 was 1770 mg/kg. However, the purity of the substance tested was not noted, hence effects could have been by an unknown impurity in this study. The high degree of water solubility and molecular weight <500 g/mol would indicate that this substance would absorb well through the gut and into the systemic circulation.
Inhalation: no data, as the substance is not volatile and not expected to be inhaled.
Dermal: KEL3587 is classified as a category 2 skin irritant. Damage to the skin barrier will allow this substance to absorb into the systemic circulation. It is a skin sensitiser in the local lymph node assay and in human volunteer studies providing evidence that it absorbs into and through the skin.
In the key study for acute dermal toxicity (Sanders, 2012), there are no reported systemic effects and no indication of the extent of absorption when the substance was dosed neat up to 2000 mg/kg. There is some limited evidence of systemic absorption from an earlier study by Fogleman (1963), where animals suffered from loss of appetite, lethargy and body weight loss. However, the purity of the substance tested was not noted, hence effects could have been by an unknown impurity in this study.
Distribution:
There are no specific data on differential distribution to organs.
Metabolism:
There is also no information on metabolism of this substance.
There is no evidence from in vitro genotoxicity studies to suggest that metabolism plays a role in the genotoxic properties of this substance. KEL3587 is non genotoxic in the absence and presence of metabolic activation.
Excretion:
No data are available to determine the pathways or extent of excretion.
