JBO is commonly used in yarn spinning. Hydrocarbons 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 these carcinogenic JBO hydrocarbons.

Furthermore, batching oil is used as the medium adding cohesion to yarn filaments. Removal via soaking, boiling, steaming or baking, etc. significantly compromises the integrity of the rope.
