I've previously posted about my first rather overenthusiastic use of soap. I grated literally half a bar of imperial leather into really hot water to get it to dissolve and then mixed it up to a 3 litre enema. I thought the world was ending and barring a couple of M&M enemas I've taken since, I've never wanted anything to come out of me faster than that enema!

The other posts below do make me wonder if I should be measuring out my soaps more accurately. I certainly don't want to do myself any permanent damage.
Last night I took the strongest soapy enema I've ever taken. I should have weighed the amount of Ivory soap rather than by approximate volume. However, I dissolved 14 tablespoons of grated soap into one liter of very hot water (i checked this later and it comes out to be between 55-60 g, or about 2/3rds of the standard bar of Ivory Soap). Allowing it to sit about five minutes, it appeared to dissolve completely. I poured that solution into the enema bag to allow it to cool. This also allowed the solution to slowly drain down into the tubing and filling the tubing and the Higginson pump.
When I came back about 20 minutes later to finish mixing the solution (basically adding water) for a 4-liter soapy enema, the solution had cooled enough so that it was starting to congeal. Adding three liters of warm water and squeezing the bag to mix the solution got it to a less gelatinous state, but the solution in the tubing was very strong and viscous. For a little extra kick, I added some glycerin.
Although I have a new double balloon retention nozzle, I used one of my long colon tubes to inject the solution very high up into the transverse colon. The tube was locked into place by both the retention ball and the retention ring.
Because the soap solution in the tube was so strong and viscous, the initial flow was pretty slow. However, as it pushed that solution into the high colon, the flow rate substantially increased. I took more than 3.5 liters before closing the valve. Hold time was 15 minutes. I wouldn't rate what I felt as severe or even very strong cramps. But it was a more definitive set of contractions than I typically experience with Ivory soap. In addition, the area at the top of my rectum was more activated than I typically experience (pulsing/random quivering type contractions) as the urge to expel got more imperative.
As soon as I unseated the retention ring and ball, I didn't get a grasp on the tubing just beyond the retention ball and the pressure fired the entire length of the tube out of my colon in less than one second. The long set of discharge contractions were quite an experience and I didn't have any sense of urgency in refilling/rinsing in order to relieve an internal distress.
There are some castile soaps that I have used that produce a great sense of burning/distress at lower concentration than Ivory. Was the kick I felt due more to the stronger soap or the glycerin? I'm not sure, but it wasn't unpleasant. The concentration of glycerin was relatively low (just under 3%) so I tend to think it was a result of the higher soap concentration.
