In addition, prolonged incubations can result in the auto-oxidation
of the substrate and condensation of the resulting quinone with tannable proteins to give a brown coloration, thereby producing a false positive pseudo-enzyme reaction (Nellaiappan & Vinayakam 1986).
The product protects carotenoids in aqueous systems and is more effective than existing rosemary extracts in auto-oxidation
models of oils.
Measured physical properties of the printed sheet follow the same trends as what is measured by observing the amount of auto-oxidation
of the production sheet.
Over longer periods of time at ambient temperature polymers also deteriorate in the solid state through auto-oxidation
The CL emission is linked to the ongoing oxidation reaction via the radical chain character of the auto-oxidation
process (see Figure 2), which at least for saturated carbon bonds is regarded as the dominating mechanism.
Pigmentation is also prevented by inhibiting auto-oxidation
of dopa and suppressing inflammatory reactions such as erythema following UV irradiation.
This strongly supports our theory about auto-oxidation
processes in sawdust and pellets.
renewable resources action group, that this is due to the auto-oxidation
drying potential of vegetable oil and vegetable fatty acids.
A mechanism of the PPD acting as auto-oxidation
chain-breaker is shown in figure 4 (ref.
FMC was the last North American producer to offer high-strength hydrogen peroxide before the electrolytic manufacturing process was supplanted by the lower cost Auto-Oxidation
Metal deactivation protects polymers from the auto-oxidation
that can occur as a result of the presence of trace metals in catalyst residues.
The cosmetic use of lemon oil should, therefore, be carefully specified for its geraniol and citral content, d-Limonene can undergo auto-oxidation
in the presence of air, forming a variety of oxygenated terpenes that can cause strong contact dermatitis, d-Limonene should be avoided in cosmetic formulations that may contain oxidizing ingredients.
