80 ETHYL LAUROYL ARGINATE<br />

expressed as the active component, ethyl-N -lauroyl-L-arginate HCl. Studies <strong>of</strong><br />

potential developmental effects have been conducted in rats and rabbits given ethyl<br />

lauroyl arginate by oral gavage during pregnancy. The material used in these<br />

studies did not meet the proposed specifications for the content <strong>of</strong> the active<br />

ingredient. There were no adverse effects on fetal survival or development.<br />

Respiratory distress reported in some rats and rabbits at higher doses was<br />

considered to be an artefactual effect resulting from gavage dosing with the irritant<br />

solution and thus was not considered to be <strong>of</strong> relevance for dietary exposure.<br />

Long-term studies <strong>of</strong> carcinogenicity were not available. However, the<br />

absence <strong>of</strong> preneoplastic lesions in the 52-week study and the absence <strong>of</strong> genotoxic<br />

activity do not suggest that ethyl lauroyl arginate has carcinogenic potential.<br />

4.2 Assessment <strong>of</strong> dietary exposure<br />

The Committee evaluated data submitted by the sponsor, as well as<br />

published information on an <strong>evaluation</strong> <strong>of</strong> ethyl lauroyl arginate completed by EFSA.<br />

Additionally, the Committee prepared international estimates <strong>of</strong> dietary exposure<br />

using GEMS/Food cluster diets.<br />

Ethyl lauroyl arginate is used in many <strong>food</strong> types, with a maximum level for<br />

the active ingredient <strong>of</strong> 200 mg/kg. Carbonated beverages could be treated at<br />

concentrations <strong>of</strong> up to 100 mg/kg. The Committee noted that use levels based on<br />

the active ingredient are approximately 15% lower than those based on the article<br />

<strong>of</strong> commerce (i.e. the use level for the article <strong>of</strong> commerce is up to 225 mg/kg).<br />

The current GEMS/Food international diets, derived from 13 clusters, were<br />

used to prepare international estimates <strong>of</strong> dietary exposure. They ranged from 1.0<br />

(cluster J) to 4.5 (cluster B) mg/kg bw per day. A few <strong>food</strong> types not expected to<br />

contribute significantly to the overall dietary exposure were not included in the<br />

international estimates.<br />

The sponsor submitted an estimate <strong>of</strong> dietary exposure to ethyl lauroyl<br />

arginate using data on <strong>food</strong> consumption from the USA. The mean dietary exposure<br />

to ethyl lauroyl arginate for the general population in the USA would be 3.0 mg/kg<br />

bw per day, and consumption at the 90th percentile would be 5.6 mg/kg bw per day.<br />

The Committee noted that EFSA reviewed the safety <strong>of</strong> ethyl lauroyl arginate<br />

in a variety <strong>of</strong> <strong>food</strong> matrices in 2007. Using the DAFNE database, the mean dietary<br />

exposure ranged from 0.14 mg/kg bw per day (France) to 0.50 mg/kg bw per day<br />

(Luxembourg), with an overall average <strong>of</strong> 0.32 mg/kg bw per day. Using individual<br />

dietary records from the United Kingdom, the mean dietary exposure ranged from<br />

0.11 mg/kg bw per day in the elderly to 0.83 mg/kg bw per day in children aged<br />

1.5–4.5 years. At the 97.5th percentile, dietary exposure ranged from 0.37 mg/kg<br />

bw per day in the elderly to 2.9 mg/kg bw per day in children aged 1.5–4.5 years.<br />

The Committee noted for comparison that treatment <strong>of</strong> all solid <strong>food</strong> in the<br />

diet (default value, 1500 g/day from the USA) at 200 mg/kg would result in a dietary<br />

exposure <strong>of</strong> 5 mg/kg bw per day. Including treatment <strong>of</strong> carbonated beverages at<br />

100 mg/kg (default value, 500 g/day from the USA) would make the total
