Chemical Identity
Omitted from this report are a number of studies conducted on [Formulation 2] (~43% Proprietary
J). The omitted studies included 21-day dermal toxicity, 90-day aerosol inhalation toxicity, and 90day
oral (feeding) toxicity in rats and neurotoxicity studies in hens. Replacement studies
subsequently commissioned by the contracting company are reviewed here.
Many health effects studies have been conducted on commercial products that are mixtures of
Proprietary J and closely related compounds: [Chemical 1], [Chemical 2], and [Chemical 3].
Typical composition data for these products are given in Table 13-1 below.
