Effect of N‐isopropyl‐N′‐phenyl‐p‐phenylenediamine
The effect of antioxidant, namely, N‐isopropyl‐N′‐phenyl‐p‐phenylenediamine (IPPD), on the adhesion properties of epoxidized natural rubber (ENR 25)‐based pressure‐sensitive adhesive was investigated. The concentration of the IPPD was varied from 0 to 5 parts by weight per hundred parts of rubber (phr).

Antioxidant activity of p-phenylenediamines studied by DSC
The most widely used antioxidants in the rubber industry are N,N′-substituted p-phenylenediamines (PPDs) , , being effective also as antiozonants with anti-fatigue effects.The mechanism of inhibition by phenylenediamines is given in Scheme 1.Benzoquinone diimines (BQDI) were isolated as reaction products of the first step.
Send InquiryEffect of antioxidant additives on oxides of nitrogen (NOx
Varatharajan et al. have stated that NO x emission for 0.025%-m concentration of p-phenylenediamine is reduced by 43.55% while HC and CO emissions are slightly increased with the addition of antioxidant additive.

p-Phenylenediamine
No information was located regarding the measurement of personal exposure to p-phenylenediamine. Acute Effects: Acute exposure to high levels of p-phenylenediamine may cause severe dermatitis, eye irritation and tearing, asthma, gastritis, renal failure, vertigo, tremors, convulsions, and coma in humans.

SCCP Opinion on p-Phenylenediamine
Submission II for p-Phenylenediamine was submitted in March 1983 by COLIPA2. The Scientific Committee on Cosmetology (SCC) has at its 48th meeting on 4 October 1991 expressed its opinion with the conclusions: “Para-phenylenediamine has moderate acute toxicity by the oral route and low toxicity by the dermal route.

Antioxidant effects of green tea - PubMed Central (PMC)
Indirect antioxidant effects of green tea Green tea polyphenols can have indirect antioxidant effects in vivo . Intraperitoneal injections with green tea polyphenols, have been shown to increase levels of phase II antioxidant enzymes in rat livers including glutathione peroxidase and reductase, glutathione-S-transferase (GST), catalase, quinone reductase, and superoxide dismutase [ 72 ].
