So this morning while I was showering I thought about something; why is it that no matter what home-made soap I've used/use (be it made by me or someone else), they never wear down the same as commercial soaps? By this I mean that any home made soap I've used has always gotten to a point where it eventually breaks into pieces where as a commercial bar will always, from my experience, retain its shape till it's a tiny little sliver of its former self. What ingredient/chemical in commercial soap causes this? Just curious.
 
It may be your recipe or something. Hard to say. My handmade soap seldom breaks or crumbles even when it is next to paper thin. I wet the sliver and a new bar of soap, then rub the sliver against the bar until it sticks. After letting the whole thing dry, the sliver will usually stay stuck to the larger bar until it's used up.
 
The ony one I've had break so far is the one I did as a three layered soap. The middle layer was colored with activated charcoal. That part of the soap dissolved quicker than the other two parts and the soap separated at that section. I've actually just pulled iut my last bar of that a few days ago and it's at the bathroom sink. It's a year old now, much harder than it was before and makes better bubbles. I'm wondering if it will break like the others did. I'll have to remember to report back on this thread if it does. Do any if your soaps have AC in them?
 
So far the only artisan soap I have had fall apart was a M&P with some kind of geometric làyers. It happened the first time I used the it, too. But my own soaps and any others have always worn normally to a little sliver just like sender bars.

I have not yet used a layered CP soap, or soaps with embeds, so don't know what would/will happen with them.

I have wondered if the mosaic soap I made will stay together, but since it was CPOPed I am hoping that helped meld it together well. Of course only time will tell.
 
Mine don't break either? Mine basically wear into a smaller, thinner rectangle. I am wondering if it is how you hold or use the soap, or store the soap in your bathroom between baths? Do you use a concave soap dish? If so, the middle of the soap is suspended over the curve and maybe the soap is gradually weakening there?
 
DH's bars normally end up breaking in half. I blame his manly scrubbing action.... Sydnet bars do the same thing with him. My bars wear away to nothingness.

My sister does this! I thought she was the only genius to think that up. I should have known...

My bars always wear down to a sliver too. I don't think I've ever had one break - handmade or otherwise.
 
my 100% CO bars seem to break apart when they wear down close to slivers. Not the salt bars but I made some laundry soap that I kept a few bars whole from. No other recipe has done this as yet, so i think it must be that.
 
I just realized that my first salt bar soap breaks apart. But I'm sure it was either something to do with the recipe or the technique. It was the first time I made them, after all. Actually I have only made them twice. I seem to be one of the few not particularly fond of salt bars.
 
Maybe it is in the way I hold the bar. I happen to love long showers and I always lather more than once (which is why my soaps never last long). I know some people that lather up then put the bar down and continue to lather with their hands only. I'm in the camp that says never let that bar out of your hands! All of my soaps seem to wear at the middle which, after a while, cause the bar to weaken and then just break. I normally fold the halves together and move on from there. Maybe shape has a lot to do with it since I don't treat commercial bars any differently and those never wear the same as home made soaps I've tried. Maybe I'll just start using the soaps more gingerly... NOT!

If this is the case then maybe you just need to make oval soap bars instead of rectangular/regular? keep the middles from wearing more than the ends?
 
I think it depends on the ingredients of the soap, the shape, the cure time, and the overall stress on the bar.

I've been told Stearic Acid and Beeswax help make strong bars, and well as hard butters and oils.

If you have strong hands, you maybe scrubbing and stress the structural integrity of the bar.
 
I think part of that may be your recipe. I would look at how much brittle oils make up your recipe. I've had a handful of soaps do that but that was mostly cure-related (they were all under the 3 month mark I set).
