Deodorants: an experimental provocation study with isoeugenol

Contact Dermatitis, 2005
Axillary dermatitis is common and overrepresented in people with contact allergy to fragrances. Many people suspect their deodorants to be the incriminating products. In order to investigate the significance of isoeugenol in deodorants for the development of axillary dermatitis when used by people with and without contact allergy to isoeugenol, patch ...

Biotransformation of Isoeugenol into Vanillin Using Immobilized Recombinant Cells Containing Isoeugenol Monooxygenase Active Aggregates

Applied Biochemistry and Biotechnology, 2019
For efficiently enhancing the activity of isoeugenol monooxygenase, a whole cell overproducing active aggregate IEM720-18A was successfully fabricated via the fusion of amphiphilic short peptide 18A (EWLKAFYEKVLEKLKELF) and isoeugenol monooxygenase and then efficiently expressed in E. coli BL21 (DE3). Such resulting bacteria, E.

Ferric chloride oxidation of isoeugenol

Experientia, 1983
Ferric chloride oxidation of isoeugenol gave 5 products. The elucidation of the structures of those products and the mechanism of their formation are discussed.

Oxidation of isoeugenol by Nocardia iowensis

Enzyme and Microbial Technology, 2008
Abstract Isoeugenol is a starting material for both the synthetic and biotechnological production of vanillin and vanillic acid. Nocardia iowensis DSM 45197 (formerly Nocardia species NRRL 5646) resting cells catalyze the conversion of isoeugenol to vanillic acid, vanillin, vanillyl alcohol and guaiacol.

Enhancing the antibacterial efficacy of isoeugenol by emulsion encapsulation

International Journal of Food Microbiology, 2016
Food spoilage and foodborne illnesses are two global challenges for food manufacturers. Essential oils are natural antibacterials that could have a potential for use in food preservation. Unfortunately high concentrations are needed to obtain the desired antibacterial effect, and this limits their use in food due to their adverse organoleptic ...

Isoeugenol: A survey of consumer patch-test sensitization

Food and Chemical Toxicology, 1983
The potential of isoeugenol, an important fragrance and flavour ingredient, to induce delayed contact hypersensitivity or to elicit pre-existing sensitization reactions in man was evaluated by analysing patch-test data from dermatitic and non-dermatitic subjects.

SENSITIZED PHOTOOXIDATION OF ISOEUGENOL TO VANILLIN

Photochemistry and Photobiology, 1979
Abstract— The photochemical conversion of isoeugenol to vanillin can proceed via the 1O2 (1Δg) state of oxygen and can be effected over a wide range of base and dye concentrations. A typical situation involving methylene blue (0.3 mM), isoeugenol (24 mM) and a base concentration of 0.1 N will give yields of approximately 35% of the theoretical amount.

Free radicals of coniferyl alcohol and isoeugenol

Australian Journal of Chemistry, 1975
E.s.r, spectra have been obtained from the free radicals formed by photolysis of coniferyl alcohol and isoeugenol in low temperature ice matrices. Analysis of these spectra indicates that the unpaired electrons are delocalized over the entire radicals and the spin densities at the β carbon atoms are about a third of an electron.
