branched, saturated and or unsaturated)-ω-hydroxypolyoxyethylene polymer with or 

without polyoxypropylene, mixture of di- and monohydrogen phosphate esters and the 

corresponding ammonium, calcium, magnesium, monoethanolamine, potassium, sodium 

and zinc salts of the phosphate esters; minimum oxyethylene content averages 2 moles; 

minimum oxypropylene content is 0 moles. The tolerance exemption descriptor under 

40 CFR 180.910 and 180.930 for AAASD is α-alkyl(C6–C15)-ωhydroxypoly(oxyethylene)sulfate, and its ammonium, calcium, magnesium, 

potassium, sodium, and zinc salts, poly(oxyethylene) content averages 2–4 moles. This 

request is to amend the existing tolerance exemptions to include additional CAS Reg. 

Nos. (See Table 1 and Table 2). A Notice of Filing for this petition was published in the 

Federal Register on June 5, 2013 (78 FR 33785). There were no comments received in 

response to this notice. 

The purpose of this document is to assess, as required under the Federal Food Drug and 

Cosmetic Act (FFDCA), the risk of the use of the additional CAS Reg. Nos. as inert 

ingredients in pesticide products and is based on a previous assessment for AAAPD and 

AAASD along with a rationale provided by the petitioner as to why the additional CAS 

Reg. Nos. can be considered safe under the existing tolerance exemption descriptors for 

AAAPD and AAASD; under 40 CFR 180.910 & 180.930. 

A previous assessment was completed on June 8, 2009 and a final rule establishing 

exemptions from the requirement of a tolerance for residues of AAAPD under 40 CFR 

180.920 and AAASD under 40 CFR 180.910 & 180.930 was published on June 17, 2009 

(74 FR 37571). A second assessment was completed on July 28, 2010 and a final rule 

establishing exemptions from the requirement of a tolerance for residues of AAAPD 

under 40 CFR 180.910 & 180.930 was published on August 20, 2010 (75 FR 51382). 

These exemptions were established based on information submitted by the JITF CST 2. 

Specific information on the studies received from JITF CST 2 to support the request to 

establish exemptions from the requirement a tolerance and the nature of the adverse 

effects caused by AAAPD and AAASD as well as the no- observed-adverse-effect-level 

(NOAEL) and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity 

studies can be found at http:// www.regulations.gov in documents “Alkyl Alcohol 

Alkoxylate Phosphate and Sulfate Derivatives (AAAPDs and AAASDs - JITF CST 2 

Inert Ingredients). Human Health Risk Assessment to Support Proposed Exemption from 

the Requirement of a Tolerance When Used as Inert Ingredients in Pesticide 

Formulations” and “Alkyl Alcohol Alkoxylate Phosphate Derivatives (AAAPD); 

Exemption From the Requirement of a Tolerance Final Rule (CST 2-JITF Submissions)” 

in docket ID number EPA-HQ-OPP-2009-0131. 

The Agency has reviewed JITF CST 2’s claim that the addition of the requested CAS 

Reg. Nos. is acceptable under the current tolerance exemption descriptors for AAAPD 

and AAASD. IIAB has confirmed that the requested CAS Reg. Nos.are appropriately 

added to the currently approved descriptorsand that no further review is required. The 

requested CAS Registry Numbers all consist of compounds that are either α-alkyl 
3 

(minimum C6 linear or branched, saturated and or unsaturated)-ωhydroxypolyoxyethylene polymers with or without polyoxypropylene, mixture of di- and 

monohydrogen phosphate esters or the corresponding ammonium, calcium, magnesium, 

monoethanolamine, potassium, sodium and zinc salts thereof with a minimum 

oxyethylene content averages 2 moles; minimum oxypropylene content is 0 moles, or αalkyl(C6–C15)-ω-hydroxypoly(oxyethylene)sulfate, or the ammonium, calcium, 

magnesium, potassium, sodium, and zinc salt thereof, with a poly(oxyethylene) content 

averaging 2–4 moles and, as such, fall within the existing tolerance exemption for 

AAAPD and AAASD given in 40 CFR 180.910 and 40 CFR 180.930. 

The Agency has determined that the proposed addition of the requested CAS Reg. Nos. is 

adequately supported by the existing data and assessment and that no additional data or 

review is required. Inclusion of the additional chemicals described above in the risk 

assessments for the alkyl alcohol alkoxylate phosphate and sulfate derivatives would in 

no way alter the prior risk assessments given the generic findings on toxicity and the 

worst case exposure assumptions used in those risk assessments. Accordingly, based on 

the findings in that earlier rule, EPA has determined that there is a reasonable certainty 

that no harm to any population subgroup, including infants and children, will result from 

aggregate exposure to alkyl alcohol alkoxylate phosphate and sulfate derivatives by 

including the additional chemicals described above, under reasonably foreseeable 

circumstances. 

Therefore, the amendment of an exemption from tolerance under 40 CFR 180.910 and 

180.930 for residues of α-alkyl (minimum C6 linear or branched, saturated and or 

unsaturated)-ω-hydroxypolyoxyethylene polymer with or without polyoxypropylene, 

mixture of di- and monohydrogen phosphate esters and the corresponding ammonium, 

calcium, magnesium, monoethanolamine, potassium, sodium and zinc salts of the 

phosphate esters; minimum oxyethylene content averages 2 moles; minimum 

oxypropylene content is 0 moles and α-Alkyl(C6–C15)-ωhydroxypoly(oxyethylene)sulfate, and its ammonium, calcium, magnesium, 

potassium, sodium, and zinc salts, poly(oxyethylene) content averages 2–4 moles to 

include the requested CAS Reg. Nos. (See Table 1 and Table 2) when used as inert 

ingredients (surfactants) in pesticide formulations applied to growing crops, raw 

agricultural commodities after harvest and to animals, not to exceed 30% of pesticide 

formulations can be considered safe under section 408 of the FFDCA. 

Table 1. Request to Amend α -alkyl (minimum C6 linear or branched, saturated 

and or unsaturated)- ω -hydroxypolyoxyethylene polymer with or without 

polyoxypropylene, mixture of di- and monohydrogen phosphate esters and the 

corresponding ammonium, calcium, magnesium, monoethanolamine, potassium, 

sodium and zinc salts of the phosphate esters; minimum oxyethylene content 

averages 2 moles; minimum oxypropylene content is 0 moles (AAAPD) under 40 

CFR 180.910 and 40 CFR 180.930 to include the following CAS Reg. Nos.
