Federal Register / Vol. 86, No. 194 / Tuesday, October 12, 2021 / Proposed Rules No release of the PMN substance resulting in surface water concentrations that exceed 260 ppb.
The proposed SNUR would designate as a significant new use the absence of these protective measures.
Potentially Useful Information: EPA
has determined that certain information may be potentially useful to characterize the human health and environmental effects of the PMN substance if a manufacturer or processor is considering submitting a SNUN for a significant new use that will be designated by this SNUR. EPA has determined that the results of eye irritation, skin sensitization, and aquatic toxicity testing may be potentially useful to characterize the health and environmental effects of the PMN
substance.
CFR Citation: 40 CFR 721.11611.
PMN Number: P1834
Chemical Name: Polyetheramine carboxylate salt generic.
CAS Number: Not available.
Basis for action: The PMN states that the use of the PMN substance will be as a dispersing agent for pigments in industrial paints and coatings. Based on estimated physical/chemical properties of the PMN substance, comparison to structurally analogous chemical substances, and comparison to analogous polycationic polymers, EPA
has identified concerns for lung effects and aquatic toxicity if the chemical substance is not used following the limitations noted. The conditions of use of the PMN substance as described in the PMN include the following protective measures:
No use of the PMN substance in a consumer product;
Use of the PMN substance only as a dispersing agent for pigments in industrial paints and coatings;
No processing beyond a maximum concentration of 1% in the formulation of the final product;
No manufacture or processing of the PMN substance in any manner that results in inhalation exposure; and No release of the PMN substance resulting in surface water concentrations that exceed 45 ppb.
The proposed SNUR would designate as a significant new use the absence of these protective measures.

determined that the results of pulmonary effects and aquatic toxicity testing may be potentially useful to characterize the health and environmental effects of the PMN
substance.
CFR Citation: 40 CFR 721.11612.
PMN Number: P18121
Chemical Name: Benzene, 1,1oxybis-, branched eicosyl derivs.
CAS Number: 1800419559.
Basis for action: The PMN states that the generic non-confidential use of the PMN substance will be as an additive for lubricating grease. Based on estimated physical/chemical properties of the PMN substance and submitted test data on the PMN substance, EPA
has identified concerns for neurotoxicity, kidney effects, and blood effects if the chemical substance is not used following the limitation noted. The conditions of use of the PMN substance as described in the PMN include the following protective measure:
Use of the PMN substance only for the confidential use described in the PMN.
The proposed SNUR would designate as a significant new use the absence of this protective measure.
Potentially Useful Information: EPA
has determined that certain information may be potentially useful to characterize the human health effects of the PMN
substance if a manufacturer or processor is considering submitting a SNUN for a significant new use that will be designated by this SNUR. EPA has determined that the results of workplace exposure monitoring may be potentially useful to characterize the health effects of the PMN substance.
CFR Citation: 40 CFR 721.11613.
PMN Number: P18168
Chemical Name: Alkoxylated triaryl methane generic.
CAS Number: Not available.
Basis for action: The PMN states that the generic non-confidential use of the PMN substance will be as a color additive. Based on estimated physical/
chemical properties of the PMN
substance, comparison to structurally analogous chemical substances, and test data submitted on the PMN substance, EPA has identified concerns for lung surfactancy if the chemical substance is not used following the limitation noted.
The conditions of use of the PMN
substance as described in the PMN
include the following protective measure:
No manufacture, processing, or use of the PMN substance in any manner that results in inhalation exposure.

CFR Citation: 40 CFR 721.11614.
PMN Numbers: P18179, P18180, and P18181
Chemical Names: Phenolic resin, alkali, polymer with formaldehyde and phenol, sodium salt generic P18
179, Phenol, polymer with formaldehyde and phenolic resin, potassium salt generic P18180, and Phenol, polymer with formaldehyde and phenolic resin, potassium sodium salt generic P18181.
CAS Numbers: Not available.
Basis for action: The PMNs state that the generic non-confidential use of the PMN substances will be as adhesives.
Based on the estimated physical/
chemical properties of the PMN
substances, comparison to structurally analogous chemical substances, and comparison to analogous polyanionic polymers, EPA has identified concerns for irritation, corrosion, and aquatic toxicity if the chemical substances are not used following the limitations noted. The conditions of use of the PMN
substances as described in the PMN
include the following protective measures:
No manufacture including import of the PMN substances to contain greater than 0.1% unbound formaldehyde residuals by weight;
No use of the PMN substances other than for the confidential uses described in the PMNs;
No manufacture of the PMN
substances such that the weight percent of low molecular weight species below 1000 daltons exceeds the confidential value specified in the PMNs; and No manufacture, processing, or use of the PMN substances in any manner that results in inhalation exposure.
The proposed SNUR would designate as a significant new use the absence of these protective measures.
