Action Plan

phthalates7.gif
EPA has issued an action plan for certain phthalates under its enhanced chemical safety program . The action plan (PDF) (16 pp, 80K, About PDF ) includes a multi-stakeholder alternatives assessment that will be conducted by EPA's Design for the Environment (DfE) Program The information developed could be used to encourage industry to move away from phthalates in a non-regulatory setting to expand risk management effects beyond whatever regulatory action might be taken under TSCA, or as input to a regulatory action. The alternatives assessment will build upon existing knowledge and will consider exposures for all human subpopulations, as well as environmental exposure. For more information on alternatives assessments go to www.epa.gov/dfe/alternative_assessments.html.

Goal

To evaluate phthalates and potential alternatives based on a range of human health and environmental endpoints, and provide this information to stakeholders for informed decision making.

Scope

This alternatives assessment will evaluate the following eight phthalates, two associated chemicals and their alternatives:

CASRN CA Index Name Acronym Common Name
84-74-2 1,2-Benzenedicarboxylic acid, 1,2-dibutyl ester DBP Dibutyl phthalate
84-69-5 1,2-Benzenedicarboxylic acid, 1,2-bis-(2-methylpropyl) DIBP Diisobutyl phthalate
85-68-7 1,2-Benzenedicarboxylic acid, 1-butyl 2- (phenylmethyl) ester BBP Butyl benzyl phthalate
131-18-0 1,2-Benzenedicarboxylid acid, 1,2-dipentyl ester DnPP Di-n-pentyl phthalate
117-81-7 1,2-Benzenedicarboxylic acid, 1,2-bis(2-eethylhexyl) ester DEHP Di(2-ethylhexyl) phthalate
117-84-0 1,2-Benzenedicarboxylic acid, 1,2-dioctyl ester DnOP Di-n-octyl phthalate
28553-12-0
68515-48-0
1,2-Benzenedicarboxylic acid, 1,2-diisononyl ester
1,2-Benzenedicarboxylic acid, di-C8-C10-branched alkyl esters, C9-rich
DINP and associated chemical* Diisononyl phthalate
Di-(C9-rich branched C8-C10-alkyl) phthalate
26761-40-0
68515-49-1
1,2-Benzenedicarboxylic acid, 1,2-diisodecyl ester
1,2-Benzenedicarboxylic acid, di-C9-C11-branchedalkyl esters, C10-rich
DIDP and associated chemical* Diisodecyl phthalate
Di-(C10-rich branched C9-C11-alkyl) phthalate

Because the need to consider all eight phthalates precludes the selection of a single application, the intent is to identify and evaluate a wide variety of alternatives that may be appropriate substitutes for a range of applications. Alternatives will be characterized by functional use and performance attributes and known and potential applications will be identified.
