JBO-Batching Oil

The toxic ingredient in jute rope for bondage.

Important facts about JBO-batching oil

Batching oil is the medium sprayed onto loose jute filaments before piling to soften them ahead of yarn manufacturing, and also adds cohesion to the yarn.

While cheaper mineral oil (JBO) is commonly used, Amatsunawa specification yarn is only batched using 100% cold-pressed Vitamin A/D fortified soybean oil.
Hydrocarbons used in mineral JBO in the C15-C20 range conclusively confirm toxicology, e.g.

  • Evaluation of carcinogenic effect of mineral oil used in the processing of jute fibres, NK Mehrotra & AK Saxena, 1979
  • Induction of benzo[a]pyrene hydroxylase in skin and liver by cutaneous application of jute batching oil, S Kumar, M Antony & NK Mehrotra, 1982
  • Quantification of tumour initiating effect of jute batching oil and its distillates over mouse skin, R Agarwal, S Kumar, Y Shukla, M Antony & NK Mehrotra, 1985
  • Polyaromatic Hydrocarbon Profile of a Mineral Oil (JBO-P) by Gas Chromatography, R Agarwal, S Kumar & NK Mehrotra, 1986
  • Jute batching oil: a tumor promoter on mouse skin, NK Mehrotra, S Kumar, R Agarwal & M Antony, 1987
  • Evaluation of carcinogenic effect of jute batching oil (JBO-P) fractions following topical application to mouse skin, R Agarwal, Y Shukla, S Kumar & NK Mehrotra, 1988
  • Carcinogenic Property of JBO(P) Variety of Jute Batching Oil, NK Mehrotra, S Kumar & M Antony, 1988
  • Role of GSSG-reductase and a thiol oxidant diethylmaleate (DEM) in skin tumorigenesis induced by jute batching oil, M Antony, S Kumar & NK Mehrotra, 1989

If your rope smells of kerosene, it contains JBO.
