List of Subjects Environmental protection, Agricultural commodities, Feed additives, Food additives, Pesticides and pests, Reporting and recordkeeping requirements. Dated: September 16, 2004. Janet L. Andersen, Director, Biopesticides and Pollution Prevention Division, Office of Pesticide Programs. Summary of Petition The petitioner's summary of the pesticide petition is printed below as required by FFDCA section 408(d)(3). The summary of the petition was prepared by AVA Chemical Ventures, [[Page 58168]] L.L.C. and represents the view of the petitioner. The petition summary announces the availability of a description of the analytical methods available to EPA for the detection and measurement of the pesticide chemical residues or an explanation of why no such method is needed. AVA Chemical Ventures, L.L.C. PP 2E6389 EPA has received a peticide petition (PP 2E6389) from AVA Chemical Ventures, L.L.C., 80 Rochester Avenue, Suite 214, Portsmouth, NH 03801. This petition proposes, pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR part 180 by establishing tolerances for the residues of the insecticide sorbitol octanoate in or on all food agricultural commodities. A. Product Name and Proposed Use Practices Sorbitol octanoate is a fatty acid ester made with sorbitol and caprylic acid derived from edible oils and fats. It is a contact insecticide that is effective against soft-bodied insects and mites. The modes of action are physical, whereby the surfactant effect of sorbitol octanoate either causes rapid suffocation or de-waxes the cuticle of the target insect, causing it to lose body fluids and dessicate. Sorbitol octanoate is sprayed in a water solution at a rate of 0.5-1.0% volume/volume throughout the growing season to control soft- bodied insects and mites. Treatments may be applied up to the day of harvest. B. Product Identity/Chemistry 1. Identity of the pesticide and corresponding residues. Sorbitol octanoate is manufactured by the esterification of sorbitol, a food- grade sweetener, and caprylic acid derived from 21 CFR-approved edible oils or fats. Sorbitol is a hexahydric alcohol with about half the sweetness of sucrose that occurs naturally in many plants, including cherries, plums, pears, apples and seaweeds. Caprylic acid (octanoic acid) is obtained from coconut oil or palm kernel oil where it is present in concentrations of 5.8% and 3-4.5%, respectively. Sorbitol octanoate is chemically similar to certain sorbitan esters which are approved by the Food and Drug Administration (FDA) for direct addition to food for human consumption (21 CFR 172.836, 172.838, 172.840 and 172.842). The only difference between the sorbitan esters and sorbitol octanoate is in the degree that water has been removed from the main sorbitol structure. Following use as a plant insecticide, sorbitol octanoate hydrolyzes rapidly into its starting ingredients, sorbitol and caprylic acid which biodegrade rapidly in the environment. 2. Magnitude of residue at the time of harvest and method used to determine the residue. Rapid hydrolysis and biodegradation ensure that the residue of sorbitol octanoate at time of harvest will be minor. 3. A statement of why an analytical method for detecting and measuring the levels of the pesticide residue are not needed. An analytical method for residues is not applicable as this petition proposes an exemption from the requirement of a tolerance. C. Mammalian Toxicological Profile Sorbitol octanoate is chemically similar to certain sorbitan esters and sucrose fatty acid esters which are approved for use as food emulsifiers and post-harvest protective fruit coatings. Both sorbitan esters and sucrose fatty acid esters have been examined in a number of toxicological studies prepared in connection with their approval by the FDA and other regulatory bodies. 1. Acute toxicity. Sorbitan esters, sucrose fatty acid esters and sucroglycerides were evaluated by the World Health Organization (WHO) for acceptable daily intake (ADI) for man in 1969, 1973, 1976, 1980, and 1982. WHO Food Additive Series No. 17 (1982), titled, ``Sorbitan Monoesters of Palmitic, Stearic, Oleic and Lauric Acids and Triesters of Stearic Acid,'' examined available animal feeding studies and concluded that a daily intake in the diet of the rat of 50,000 parts per million (ppm) (5%) causes no toxicological effect. This level of intake is equivalent to 2,500 milligrams/kilogram (mg/kg) of body weight (bwt). An estimate of acceptable daily intake in man is 0-25 milligrams/kilogram (mg/kg) of body weight. WHO Food Additive Series No. 15 (1980), titled, ``Toxicological Evaluation of Certain Food Additives,'' reports on the results of sucrose fatty acid esters administered in short-term feeding studies to dogs and a long-term feeding study of rats. No effects attributable to the ingestion of sucrose fatty acid esters were found in any of the studies. The WHO concluded the ingestion level in rat to be 10,000 ppm (1.0%) in the diet, equivalent to 500 mg/kg of bwt. The American Chemical Council's Aliphatic Esters Panel evaluated the mammalian toxicity of the sorbitan esters that are approved for food and cosmetic ingredient use. The Panel concluded that metabolism of the sorbitan esters in animals occurs via enzymatic hydrolysis to sorbitan and the corresponding natural fatty acids. These substances in turn metabolize further to either smaller and more polar water-soluble metabolites excretable in the urine or as carbon dioxide exhaled in the lungs. Primary eye irritation studies were performed on rabbits by AVA Chemical Ventures, L.L.C. with manufacturing use product (MUP) sucrose octanoate fatty acid esters and with MUP sorbitol octanoate. MUP sucrose fatty acid esters were found to be severely irritating to the eye and sorbitol octanoate was found to cause substantial but temporary eye injury. Primary skin irritation studies performed on rabbits by AVA Chemical Ventures, L.L.C. with MUP and end use product (EUP) sucrose octanoate fatty acid esters were submitted to EPA in connection with the registration of that compound as a pesticide active ingredient. Both the MUP and the EUP were found to be slightly irritating to the skin. The Cosmetic Ingredient Review Expert Panel published a comprehensive review of sorbitan fatty acid esters titled, ``Final Report on the Safety Assessment of Sorbitan Caprylate, Sorbitan Cocoate, Sorbitan Diiostearate, Sorbitan Dioleate, Sorbitan Distearate, Sorbitan Isostearate, Sorbitan Olivate, Sorbitan Sesquiiostearate, Sorbitan Sesquistearate and Sorbitan Triiostearate,'' International Journal of Toxicology. (2002). The study concluded that the sorbitan fatty acid esters were generally minimal to mild skin irritants in various animal studies and were generally not ocular irritants. The Expert Panel concluded that the sorbitan fatty acid esters are safe as used in cosmetic formulations at concentrations of up to 20%. 2. Genotoxicity. The components of sorbitol octanoate (sorbitol and caprylic acid) already have regulatory approval and are commonly consumed in foods. Caprylic acid (octanoic acid) is approved by the FDA as a generally recognized as safe (GRAS) substance and direct food additive. (21 CFR 184.1025 and 21 CFR 172.860). Sorbitol has been affirmed as GRAS by the FDA and is widely used as a sweetener in foods (21 CFR 184.1835). 3. Reproductive and developmental toxicity. Sorbitol octanoate is chemically similar to sucrose fatty acid esters. In 1976, in WHO Food Additive Series No. 10, the WHO reported on the results of a reproduction study over three generations of rats using sucrose [[Page 58169]] fatty acid esters at 0 and 1% of the diet for control and test groups, respectively. Mean litter size, physical appearance and growth of litter were comparable among test and control groups. A 1986 study concluded that sorbitol administered in the diet to three successive generations of rats at levels up to 10% had no adverse effect on growth or reproductive performance in either sex. 4. Subchronic toxicity. WHO Food Additive Series No. 15 (1980) reports the findings of a study in which sucrose fatty acid esters made from beef tallow were fed to beagle dogs at concentrations of 3,000, 10,000, or 30,000 ppm for 26 weeks. A control group was fed an identical diet with the exception of the sucrose fatty acid esters. Body weight changes, food intake, and water consumption were not affected by the administration of the esters. The opthalmic and haemotologic examinations, urinalysis, organ weights, and macroscopic examinations revealed no adverse effects which could be attributed to the intake of the sucrose fatty acid esters. The blood chemistry studies showed that the majority of parameters measured were within acceptable limits. 5. Chronic toxicity. An unpublished paper titled ``Study of Chronic Toxicity of a Sucrose Ester of Fatty Acids'' (undated) was submitted to the FDA in connection with the registration of sucrose fatty acid esters as food additives. For up to 76, weeks mice and rats were fed standard feed to which had been added up to 3.0% sucrose fatty acid esters. Animals were examined for body weight, feed consumption, hematological findings, organ weights, and histopathology of organs. No particular changes resulting from administration of sucrose fatty acid esters were found. 6. Animal metabolism. Sorbitol octanoate is manufactured from fatty acids produced from 21 CFR-approved edible fats and oils. 7. Metabolite toxicology. The components of sorbitol octanoate (sorbitol and caprylic acid) already have regulatory approval and are commonly used in foods. Caprylic acid (octanoic acid) is obtained from coconut oil or palm kernel oil where it is present at concentrations of 5.8% and 3.0-4.5%, respectively. Caprylic acid (octanoic acid) is approved by the FDA as a GRAS substance and direct food additive (21 CFR 184.1025 and 21 CFR 172.860). D. Aggregate Exposure 1. Dietary exposure--i. Food. Sorbitol octanoate is chemically similar to certain sorbitan esters which are FDA-approved for direct addition to food for human consumption (21 CFR 172.842, 172 836, 172.838, 172.840) and to sucrose fatty acid esters which are FDA- approved as food emulsifiers and as coatings for certain fruits (21 CFR 172.859). The FAO/WHO Joint Expert Committee on Food Additives has evaluated sorbitan monoesters of palmitic, stearic, oleic and lauric acids, and triesters of stearic acids and has established an acceptable ADI of 0- 25 mg/kg bwt/day. The FAO/WHO has established an acceptable ADI of 10 mg/kg of bwt for sucrose fatty acid esters. Current world consumption of sucrose fatty acid esters in food applications is estimated to be 7,000 metric tons and consumption of sorbitan esters in food applications is estimated to be 50,000 metric tons. Pesticide use of sorbitol octanoate and sucrose fatty acid esters would increase usage by approximately 2,000 metric tons. As the ester bond is one of the weakest in nature, the sorbitol octanoate applied to crops will hydrolyze into its constituent ingredients which will themselves biodegrade prior to consumption of the crops to which it is applied. ii. Drinking water. No drinking water exposure is anticipated as sorbitol octanoate is not soluble in water and biodegrades rapidly following use. 2. Non-dietary exposure. Non-occupational, non-dietary exposure is highly unlikely given that inhalation or dermal absorption of sorbitol octanoate are not feasible. E. Cumulative Exposure Sorbitol octanoate is a non-toxic material made from edible starting materials (sorbitol and caprylic acid), which are commonly consumed in foods. Sorbitol octanoate biodegrades rapidly following use. A cumulative risk assessment is therefore not necessary. F. Safety Determination 1. U.S. population. Sorbitol octanoate is manufactured from raw materials (sorbitol and caprylic acid) that are affirmed as GRAS and are commonly used in foods. Sorbitol octanoate is chemically similar to sorbitan esters which are FDA-approved under 21 CFR 172.842, 172.836, 172.838, and 172.840 for direct addition to food for human consumption and to sucrose fatty acid esters which are approved as food emulsifiers and fruit coatings under 21 CFR 172.859 and to certain sorbitan esters which are approved under 21 CFR 172.842, 172.836, 172.838, and 172.840 for direct addition to food for human consumption. Based on these materials' low-risk profiles, there is reasonable certainty that no harm to the U.S. population will result from aggregate exposure to sorbitol octanoate used as an insecticide. 2. Infants and children. Sorbitol octanoate is manufactured from edible raw materials that are widely used in foods. Sorbitol octanoate is chemically similar to sorbitan esters which are approved for direct addition to food for human consumption and to sucrose fatty acid esters that are approved for use as food emulsifiers and as protective coatings applied to fruits. Due to the extensive data base documenting the low toxicity of the sorbitan esters and the sucrose fatty acid esters, AVA Chemical Ventures, L.L.C. does not believe a safety factor analysis is necessary in assessing the risk of sorbitol octanoate used as an insecticide. For the same reason, AVA Chemical Ventures, L.L.C. believes an additional safety factor analysis is unnecessary. G. Effects on the Immune and Endocrine Systems Sorbitol octanoate is not derived from nor contains any compounds which are known to be, or suspected to be, endocrine disruptors. H. Existing Tolerances Sorbitol octanoate esters are chemically similar to sorbitan esters which are approved for direct addition to food for human consumption and to sucrose fatty acid esters which are approved for use as food emulsifiers and as protective fruit coatings under 21 CFR 172.859 and to certain sorbitan esters which are approved under 21 CFR 172.842, 172.836, 172.838, and 172.840 for direct addition to food for human consumption. An exemption from the requirement of a tolerance has been established for residues of sucrose octanoate esters in or on all food commodities when used in accordance with good agricultural practies. (40 CFR 180.1222). I. International Tolerances Sorbitol octanoate esters are chemically similar to sorbitan esters and to sucrose fatty acid esters. Sucrose fatty acid esters are approved for use as food emulsifiers in Europe under E-470 and by the Joint FAO Expert Committee on Food Additives at an ADI of 10 mg/kg bwt/ day. Sorbitan esters are approved in Europe for use as food emulsifiers under various E numbers and are also approved by the joint FAO/WHO Expert Committee on Food Additives at an ADI of up to 25 mg/kg bwt/day. [[Page 58170]] There are no CODEX maximum residue levels established for residues of sorbitol octanoate. [FR Doc. 04-21588 Filed 9-28-04; 8:45 am] BILLING CODE 6560-50-S
