CONSUMER PRODUCT SAFETY COMMISSION
Notice of Meeting of Chronic Hazard Advisory Panel on Diisononyl
Phthalate (DINP) and Opportunity for Public Comment
AGENCY: Consumer Product Safety Commission.
ACTION: Notice of meeting.
-----------------------------------------------------------------------
SUMMARY: The Commission announces the second meeting of the Chronic
Hazard Advisory Panel (CHAP) on diisononyl phthalate (DINP). The
Commission appointed this CHAP to advise the Commission on any chronic
hazards of cancer, birth defects, and gene mutations associated with
children's products containing DINP. The public may submit written or
oral comments on the issues to be considered by the CHAP.
DATES: The opportunity for the presentation of oral comments will be on
June 20 from 10 a.m. to 5 p.m. The remainder of the meeting will be
held from 8:30 a.m. to 5 p.m. on June 21 and from 8:30 a.m. to 4 p.m.
on June 22, 2000.
Requests to present oral comments, and a written copy of the text
of the oral comments, must be filed with the Office of the Secretary no
later than June 13, 2000.
Written comments must be received no later than June 13, 2000.
ADDRESSES: The meeting will be held in the fourth floor hearing room in
the Commission's offices at 4330 East-West Highway, Bethesda, Maryland.
Written comments, or requests to present oral comments and the
written text of such comments, should be mailed, preferably in five
copies, to the Office of the Secretary, Consumer Product Safety
Commission, Washington, D.C. 20207-0001, or delivered to the Office of
the Secretary, Consumer Product Safety Commission, Room 502, 4330 East-
West Highway, Bethesda, Maryland; telephone (301) 504-0800. These items
also may be filed by telefacsimile to (301)504-0127 or by email to
cpsc-os@cpsc.gov. These items should be captioned ``CHAP on DINP.''
FOR FURTHER INFORMATION CONTACT: Concerning requests and procedures for
oral presentations of comments: Rockelle Hammond, Docket Control and
Communications Specialist, Consumer Product Safety Commission,
Washington, DC 20207; telephone: (301) 504-0800 ext. 1232; email cpsc-
os@cpsc.gov. For all other matters: Marilyn Wind, Directorate for
Health Sciences, Consumer Product Safety Commission, Washington, D.C.
20207; telephone (301) 504-0477, ext. 1205; email mwind@cpsc.gov.
SUPPLEMENTARY INFORMATION: The Commission has been concerned with
potential risks posed to children under 3 years of age by the
plasticizer diisononyl phthalate (DINP), which is used to soften some
children's teethers, rattles, and toys made from polyvinyl chloride
(PVC). DINP can leach from such products when they are mouthed or held
by children, causing some DINP to be absorbed through skin and mucous
membranes. DINP has been shown to cause liver and other organ toxicity
in laboratory animals. Also, the Commission has received a petition
(No. HP 99-1) from the National Environmental Trust and eleven other
organizations asking that the Commission ban PVC in children's
products.
The Commission appointed a seven-member CHAP to evaluate the
existing scientific information regarding the mechanism by which DINP
may cause cancer and the implications of this on the potential cancer
risk to children. The CHAP members were selected from scientists
recommended by the National Academy of Sciences. See 15 U.S.C. 2077,
2030(b). The first meeting of the CHAP was on May 10-11, 2000. The
second meeting of the CHAP will be on June 20-22, 2000, in the fourth
floor hearing room at the Commission's offices in Bethesda, MD (see
address above).
The CHAP is seeking public comment on issues relating to the
hazard, exposure, and risk posed by DINP in children's products. It is
interested in comments and data pertaining to: (a) What the appropriate
Acceptable Daily Intake (ADI) of DINP would be; (b) which critical
endpoint to use to determine the ADI; (c) the mechanism by which DINP
causes cancer in rodents and the relevance of these induced neoplasms
to human risk; (d) the appropriate risk assessment model or models to
determine human risk; (e) the differential sensitivity/susceptibility
of young children to the effects of DINP, if any, and how to
incorporate that into an assessment of risk; and (f) age-dependent
pharmacokinetic differences. In addition, it is particularly interested
in the following:
1. Are Diisononyl Phthalate (DINP) rodent cancer bioassay data
inapplicable to human hazard identification?
2. Is there convincing evidence that a linear extrapolation
approach for risk assessment is not appropriate for DINP?
3. What is the most appropriate measure of the biologically
effective dose for DINP-induced liver cancer?
4. Any data available on the percutaneous absorption of DINP.
(Provide any data available on absorption of DINP from the oral
mucosa.)
5. Any available data on the pharmacokinetics of DINP including
salivary metabolism.
6. Any available data on DINP metabolites.
7. Any available information on spongiosis hepatis.
8. Total exposure to phthalates in adults and children.
9. Toxicological interactions between phthalate esters.
The CPSC would appreciate it if any suitable data are submitted in
the form of an Excel Spread Sheet, a space delimited ASCII file, or a
SAS (SD2 or SSD) dataset.
There will be an opportunity for oral comments on June 20, from 10
am to 5 pm. As explained at the beginning of this notice, persons
wishing to present oral comments must file a request, and a written
copy of the text of their comments, with the Commission's Office of the
Secretary no later than June 13, 2000.
Commenters should limit their presentations to approximately 15
minutes, exclusive of any periods of questioning by the members of the
CHAP or the CPSC staff. The CHAP reserves the right to further limit
the time for any presentation and to impose restrictions to avoid
excessive duplication of presentations.
Interested persons may also file written comments with the CHAP.
Written comments must be filed with the Office of the Secretary no
later than June 13, 2000.
The remainder of the CHAP meeting will be from 8:30 a.m. to 5 p.m.
on June 21 and from 8:30 a.m. to 4 p.m. on June 22, 2000. During this
part of the meeting, the CHAP will discuss issues and the report it
will write.
Dated: May 24, 2000.

Secretary, Consumer Product Safety Commission.
