Chemical Infused Rope for Sadistic Shibari/Kinbaku
Post Body

I'm working on a prototype idea for what I hope will be a truly hellacious finalè to a sadistic shibari shoot I'm bottoming for & decided to share!

I'm taking a capsaicin extract (3M SHU or approximately 18% by weight) and dissolving about a teaspoon of it into 4L of 70% Isopropanol (I'd have used 91% or 99% if the store wasn't out of stock). I used alcohol because capsaicin is highly soluble in them - moreso than even lipids - but not soluble in water. Alcohol also acts as a transport medium for the capsaicin through the epidermis, but that won't be a feature I'm taking advantage of here.

Had I wanted to put in the effort I could have distilled it to pure isopropanol but I figured the 1L of water mixed in wasn't gonna be too much of an issue.

I then added two lengths of untreated sisal rope (one 4mm and one 6mm) to the solution to soak for the next few days to absorb as much of the solution as it can. Then I'll either take one out and put another run in and let that one dry, or I'll boil off the fluid to concentrate the capsaicin and then swap them out.

Since the alcohol will boil off first I'm unsure of what effect the high water content will have on the strength. That'll be an experiment. I may keep these two ropes to dry conventionally and then the last rope to boil down.

I should also note I'm gonna boil it off outside and wear a respirator. The alcohol will transport the capsaicin and when heated will give off fumes that will work like a strong pepper spray or mace. It will also react and give that off if you try to wash it away with a water faucet as it'll throw little droplets of the low density alcohols and oils into the air. It's nasty stuff in these concentrations and volatile (meaning "high vapor pressure and aerosolizing) organic (meaning carbon containing and carboxylic reacting) solutions.

What do yous think 😈😈😈?

I'm not sure πŸ˜… I've never done a sadistic tying scene before but I really love going to that totally overwhelmed and "broken" space. It's gonna be the finale because I'm definitely already going to be exhausted and sore by then so It's the part that I hope pushes me over that edge into a total liberating collapse and freedom from any attempts at composure, endurance, or "handling" the situation and into pire experience.

It's definitely not a place for everyone but I love going to those places. If I were in the Hellraiser universe (the Clive Barker one) I'd be very tempted by the puzzle box. Definitely a better option than an ordinary boring "heaven" if I had to pick 😈😈😈

External to the stomach and intestines capsaicin (outside of like a 90% concentration where it's just a bit less acidic than vinegar) it's totally harmless. It just happens to bond to the same sensory receptors your body uses to detect if you have a severe burn, so it's a purely sensory experience. You can go as painful as your body is able to experience if you wanted to, and you'd come out with no (direct) physical harm at all.

Buy a concentrated oil extract instead. The chemical process to go from a 20%/50%/70% extract to a pure crystal is very expensive so the pure form is more expensive than you'd expect. It's $15 to $30 per gram.

For reference a gram is enough to dilute to make something as strong as a Carolina Reaper chili is adding about 16 grams of oil. It will also dissolve fully in only 33ml of ethanol or about 37ml of Isopropanol. It's not really the most effective way to get it.

Compared to a 3M SHU concentrate that's $45 per fluid ounce: 1 fl Oz of 3M SHU ~ 0.1875 Oz of Capsaicin concentrated. That's a volume of about 5ml if it were pure and dry. Capsaicin has a density of about 1 mg/ml so 5ml ~ 5mg so even with a 50% error you're going to get 3-5 times the use out of it. PLUS the fact that it's much easier to handle, if a little less consistent.

Also keep in mind it adds the extra steps: capsaicin -> fluid -> solution -> dilution -> process -> depositing as opposed to just dilution - depositing.

Realistically if you want the best value it's a 9M SHU extract (about 70%) if you can get jt for under $100. You'll have a much harder time working with it though as it's a resin and not a liquid at that point.

The main use of powdered capsaicin is in making medical compounds, bulk manufacturing of sauces, and in calibration of measurement processes. You don't really need to buy something that's a stronger concentrate than what you're hoping to make since you'll just end up diluting it anyway, and unless you buy all the lab glass, measuring equipment, distillation apparatus, and a really precise lab scale, and learn how to set it all up and use it, you're not gonna be precise enough for it to make a meaningful difference in the finished product's consistency.

Ultimately it's also a lot more hazardous since powders can get blown up into the air and it's actually able to do damage to the eyes, mucus membranes, and lungs at that high of a concentration so you need a full face respirator ant preferably a tyvex suit to prevent you from accidentally carrying it out of the "lab" environment. Fluids are the way to go.

I posted a reel of the process to my Instagram and yes, it's for video shoot. I'm terrified and excited for it. Not sure when I'll be releasing it due to editing, credits, clearance &c. Hopefully sometime in February or March. Post is a long process when you're doing it all yourself πŸ˜….

  • I taught myself a lot about chemistry growing up since science, anatomy, and medicine were autistic special interests if mine. In college I tutored a friend in some of the advanced math they needed for chemistry in exchange for some chemistry knowledge. Then I took that and ran with it and developed a special interest in pharmacology, neuropharmacology, and toxicology in particular. After that I just kept on going.

  • I have no idea but it's very unlikely. When I got some of the alcohol in my skin every time it got wet or I started sweating it burned for about 12 hours. The nerve endings that respond to capsaicin aren't very numerous there so it wasn't too bad. I expect the initial burn to last 45 minutes or so, and the flashbacks to happen every 12 hours or so. I'll probably bring alcohol to wash off my skin when it's over to help clear it up. I'll probably also cry in the shower from the flashbacks that night.

  • The Capsaicin is a crystal in its pure form and a sticky residue in high concentrations. I expect tiny little fragments of the crystals to form on any microscopic rough parts of the fibers. These will then rub off as it scratches skin and disolve into the skin oils and sweat as they're used. So they'll lose effectiveness over time, a fresh alcohol soak may bring some of it back but it'll be less potent. Eventually (probably after 3-5 uses) it'll lose it all.

  • If it works this will feel like a severe burn that keeps getting worse for about 20 minutes, like the rope is hot metal and on fire.

  • Yes, the more exposure time the worse it gets, especially since every movement will run more into my skin and make more scratches.

  • being bound with nettles would be a fun but even longer lasting awful experience. I'm totally down to try it 😈😈😈😈.

Oh, this over is all me πŸ˜….

That said as far as the sadistic rope work they've planned I'm pretty in the dark. All I know is:

  • 2 tops for the scene
  • one floor tie
  • one full suspension
  • one partial suspension with the spicy rope; likely with a crotch rope

Beyond that I'll find out the details when they happen 😊😊☺️☺️😁😁😁

I don't always let dominants go HAM like this without being part of the planning - especially for a shoot but the anticipation and the unknown really do it for me when I trust the dominant and their skills. Plus genuine surprise and the sudden shock of realization about how a predicament or torture works look super good on camera 😈😈😈😈

I've seen the people I'm working with play a lot, how they've handled emergencies, and how they work. They've also done a few less intense ties on me so I'm comfortable with how we roll together. It's gonna be a really good time ☺️☺️☺️

If I had room in the freezer maybe, but I've also found that with higher alcohol concentrations it just turns into a slush since the water isn't able to form chunky crystals as easily.

I'd have distilled the alcohol to a higher purity before hand but it takes a while and it's still (tehe) a lot of work. I'm hoping by heating the solution with enough energy to boil off both it'll just leave a mostly dry rope behind that will evaporate off easily.

Yeah, water reactivates it and it will cause flashbacks for a while. I'm not certain of the mechanism but I know that the nerves have a refractory period where the electrical potential shifts to be fully "active" and then not much change can occur and your brain starts to ignore it. I'm guessing water resets the electrical potential in some way so if there's still enough capsaicin under the skin to bond to the receptors it will re-signal the brain with a new potential change. It may also hit a refractory point in the transition from the peripheral nerves to the spinal nerve column since there's a change in neurons there that might block a "stuck" potential from re-signaling.

The only real risk is inflammation on the skin, which can be painful but not really dangerous. Ultimately it's just extra blood flow to help heal it if there's a burn. Since there isn't it's pretty benign. Eyes it can cause more harm, but mostly due to particulates abrading the cornea when you rub or blink them. It's actually kinda amazing how safe it is.

Now, there's a lot to be said for the risk of a cardiac episode from the sudden extreme pain, but that's a risk with any heavy pain play.
