II. What Action is the Agency Taking?
EPA has received pesticide petitions as follows proposing the
establishment and/or amendment of regulations for residues of certain
pesticide chemicals in or on various food commodities under section 408
of the Federal Food, Drug, and Comestic Act (FFDCA), 21 U.S.C. 346a.
EPA has determined that these petitions contain data or information
regarding the elements set forth in section 408(d)(2); however, EPA has
not fully evaluated the sufficiency of the submitted data at this time
or whether the data support granting of these petitions. Additional
data may be needed before EPA rules on the petitions.

Summaries of Petitions
The petitioner summary of the pesticide petitions are printed below
as required by section 408(d)(3) of the FFDCA. The summaries of the
petitions were prepared by the petitioner and represents the view of
the petitioner. EPA is publishing the petitioner's summaries verbatim
without editing it in any way. The petitioner's summaries announces the
availability of a description of the analytical methods available to
EPA for the detection and measurement of the pesticide chemicals
residues or an explanation of why no such method is needed.
3. PP 6E4759
EPA has received a pesticide petition (6E4759), to amend 40 CFR
part 180, to establish an exemption from the requirement of a tolerance
for ethyl methylphenylglycidate when used as an inert ingredient in the
pesticide formulations applied to growing crops or to raw agricultural
commodities after harvest under 40 CFR 180.1001(c) and applied to
animals under 40 CFR 180.1001 (e). EPA has determined that the petition
contains data or information regarding the elements set forth in
section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated
the sufficiency of the submitted data at this time or whether the data
support granting of the petition. Additional data may be needed before
EPA rules on the petition.
A. Residue Chemistry
Since the petition is for an exemption from the requirement of a
tolerance, an analytical method is not required.
B. Toxicological Profile
As a part of the EPA policy statement on inert ingredients
published in the
Federal Register of April 22, 1987 (52 FR 13305) (FRL -3190-1), the
Agency set forth a list of studies which can generally be used to
evaluate the risks posed by the presence of an inert ingredient in a
pesticide formulation. However, where it can be determined without that
data that the inert ingredient will present minimal or no risk, the
Agency generally does not require some or all of the listed studies to
rule on the proposed tolerance or exemption from the requirement of a
tolerance for an inert ingredient.
The date that Firmenich believes supports establishing an exemption
from tolerance is summarized below. More detailed information has been
provided to the Agency.
Ethyl methylphenylglycidate has been used in foodstuffs as a
flavoring agent since the 1930's and is approved by the FDA as GRAS (21
CFR 182.60) and by the Council of Europe as in the list of substances
granted "A status"-- may be used in foodstuffs (COE No. 6002). It is
recognized by the flavor and extract manufacturer's association as GRAS
(GRAS 3 (2444)).
1. Acute toxicity. The LD50 of ethyl
methylphenylglycidate has been determined to be 5.47 g/kg for the rat,
5.6 mL/kg for the mouse, and 4.05 g/kg for the guinea pig.
Due to the very low water solubility of ethyl methylphenylglycidate
and the octanol/water coefficient (estimated Kow 3.0), acute aquatic
toxicity testing is thereby precluded.
2. Genotoxicty. An Ames tests with S-9 fractions from Aroclor-
pretreated rats at doses up to 3.6 mg/plate with and without S-9 gave
no adverse effect. Similarly, an Ames test, with strains TA98, TA 100,
TA1535, TA1537 and TA97, also gave no adverse effects. A Drosophila
melagaster and micronucleus test on mouse bone marrow appeared weakly
mutagenic in the Drosophila only.
A chinese hamster ovary (CHO) cell study with ethyl
methylphenylglycidate treated 8-12 hours without rat S-9 and 2 hours
with S-9, gave positive sister chromatid exchange effects without S-9
over the full range of doses tested, 16 - 160 g/mL, and no
effect with S-9 over the whole range. Similarly, there were significant
increases in chromosome aberrations over the range 50-500 g/mL
with and without S-9.
3. Reproductive and developmental toxicity. Toxicity and
teratogenicity of ethyl methylphenylglycidate was evaluated in chickens
with mortality and structural & functional defects being evaluated. The
teratogenicity NOEC was 25 mg/egg and the LD50 was 8.16 mg/
A mouse carcinogenicity and mutagenesis study was conducted in 15/
sex/dose male and female mice by intraperitoneal injection 3X per weeks
for 8 weeks at the maximum tolerance dose (MTD) and 0.20X MTD of ethyl
methylphenylglycidate. There were 10 deaths at 0.45 g/kg and 4 deaths
at 2.15 g/kg. Similarly, an intraperitonile ethyl methylphenylglycidate
study with male and female mice showed no effects at the highest dose
treated, 1,856 mg/kg.
4. Subchronic toxicity. In a 16-week rat study with male and female
Osborne-Mendel rats at 10,000 parts per million (ppm) ethyl
methylphenylglycidate weight changes, reproductive effects, growth
retardation in males, and marked testicular atrophy was observed. In a
1-year study with male and female Osborne-Mendel rats, no effects were
observed at 2,500 ppm of ethyl methylphenylglycidate on growth,
haematology or macroscopic/microscopic tissue examination. In a second
study, ethyl methylphenylglycidate, was fed to male and female rats for
15 weeks at 0.0, 0.02, 0.1, and 0.5% in the diet. No effect was
observed on the growth rate, food consumption, or water consumption of
the animals. The only effect attributable to the test substance were
increased organ weight changes in the animals fed at the 0.5% level.
The no observed adverse effect level was 0.1% ethyl
methylphenylglycidate, corresponding to 150 and 60 mg/kg/day
respectively at the beginning and end of the study.
5. Chronic toxicity. In a rat study, male and female rats were fed
for 1.5 to 2 years at 0.1% and 0.5% ethyl methylphenylglycidate in
their diet. No effects were observed at the 0.1% level. At 0.5% in the
diet, neurotoxic effects, body weight (bwt) changes, pareses of the
rear extremities with histological degeneration of the ischia nerve,
and growth inhibition were observed. In a second study with 48 Wistar
rats/sex at 0, 0.02, 0.1, and 0.5 EMPG in the diet for 2 years, no
effects were observed at 0.1% (EMPG intake of approximately 35 mg/kg/
day ethyl methylphenylglycidate for the males and 60 mg/kg/day ethyl
methylphenylglycidate for the females). At 0.5%, weight changes, liver,
micropathology in other organs, significant decrease in body weight in
females, increased incidents of histopathology changes in lymph nodes,
pancreas, adrenal glands, and liver were noted. No differences in
mortality, hematology, serum chemistry, renal function, organ weights,
or motor coordination were observed at any dose.
6. Endocrine disruption. Ethyl methylphenylglycidate is not
structurally similar to any substances know to be an endocrine
C. Aggregate Exposure
Consistent with section 408(c)(2)(B) of FFDCA, Firmenich
Incorporated believes that, based on this submission, the Agency has
sufficient information to assess the hazards of ethyl
methylphenylglycidate and make a determination on aggregate exposure,
consistent with section 408(b)(2) for tolerance exemption for the
residues of ethyl methylphenylglycidate on growing crops, RACs after
harvest, and animals.
Dietary exposure. For the purpose of assessing the potential
dietary exposure under these exemptions, Firmenich Incorporated
considers that ethyl methylphenylglycidate could be present in all raw
and processed agricultural commodities.
1. Food. Ethyl methylphenylglycidate is a GRAS substance 21 CFR
182.60 and is included by the Council of Europe in the list of
substances granted"A status"--may be used in foodstuffs (COE No.
6002). The flavors and extract manufacturer's association states:
Generally recognized as safe as a flavor ingredient--GRAS 3, (2444).
The Joint Expert Committee on food additives has established an ADI of
0.5 mg/kg (1984). Therefore, no concerns for risk associated with any
potential exposure scenarios are reasonably foreseeable.
2. Drinking water. Due to the low water solubility (estimated 87
mg/L by ECOSAR), only very low drinking water exposure is expected and
would not contribute significantly to the ADI. Therefore, no concerns
for risk associated with any potential exposure scenarios are
D. Cumulative Effects
Section 408(b)(2)(D)(v) of FFDCA requires that, when considering
whether to establish, modify, or revoke a tolerance or tolerance
exemption, the Agency consider "available information" concerning the
cumulative effects of particular chemical's residues and "other
substances that have a common mechanism of toxicity". Ethyl
methylphenylglycidate has been in public use since the 1930's and the
lack of observed toxicity after acute and chronic exposure would
suggest that a cumulative risk assessment is therefore not necessary.
E. Safety Determination
1. U.S. population. Ethyl methylphenylglycidate has been granted
self-affirmed GRAS status in the United States, is approved for food
use in Europe, and by the WHO Joint Expert Committee on food additives,
ADI of 0.5 mg/kg. Based on this material's low-risk profile, there is
reasonable certainty that no harm to the U. S. population will result
from aggregate exposure to ethyl methylphenylglycidate.
2. Infants and children. FFDCA section 408 provides that EPA shall
apply a ten-fold MOE for infants and children in the case of threshold
effects to account for prenatal and postnatal toxicity and the
completeness of the data base unless EPA concludes that a different
margin of safety will be safe for infants and children. Margins of
safety are incorporated into EPA's risk assessment either directly
through the MOE analysis or through using uncertainty (safety) factors
in calculating a dose level that pose no appreciable risk to humans.
Due to the extensive available toxicological data base including
chronic toxicity studies and the expected low toxicity of this
compound, Firmenich Incorporated does not believe a safety factor
analysis is necessary in assessing the risk of these compounds. For the
same reasons, Firmenich believes the additional safety factor is
F. International Tolerances
There are no known international tolerances for ethyl methyl-
