JBO in rope

by | Oct 31, 2018 | Blog

The second rope set I bought came from a supplier in Europe. After having my partner tied several times with it, she started showing some allergic reactions on her skin. Though I read about it before, I still was not convinced it would be the rope itself causing the reaction.  

While doing some experiments with cleaning rope, I boiled one of the ropes for about 10 minutes when my partner came walking in, noticing the smell of a medium sized Pratt & Whitney Jet engine. Well, it must have smelled that way. Without overreacting the whole house had a smell of kerosine. A very penetrating and nauseating smell. A smell it had not when the shipment came in. It was probably the outer skin of the rope that had ‘aired’ long enough to loose the smell, but getting into the core of the rope by boiling it, it released quite some carcinogenic substances.

When doing some more research and talking to my supplier, we found several research documents pointing at the potential risk for human tissue and health in general through the use of Jute Batching Oil (JBO) based on fossil fuels, in some cases containing very unhealthy levels of carcinogenic substances. 

We cannot keep this knowledge under the radar and when knowing it, not act on it. It is a fable that only the use of petroleum based batching oil is the only approach to secure rope strength and safety. Not so, we only need to change some parameters to enable the use of organic oil and have the same effects. 

If you are really into science, love the scientific babbling or just want to convince yourself. Read the research docs below. They contain all the date to only demand clean rope from your supplier. We intend to share a lot more of our knowledge in the coming months, so stay tuned for more insights into rope for bondage.

JUTE BATCHING OIL

JBO is commonly used in yarn spinning. Hydrocarbons in the C15-C20 range conclusively confirm toxicity, 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

SELF TEST

If your rope smells of kerosene, it contains these carcinogenic JBO hydrocarbons. Batching oil is used as the medium to add cohesion to yarn filaments. Removal via soaking, boiling, steaming or baking, etc. significantly. We run all our rope though a mass spectrography test to ensure clean rope, batched with organic oil and coated with human- and eco friendly substances.
