For what it's worth, my Castile's produce a smorgasbord of slime no matter how old they are. lol
Last month I nearly jumped for joy when I found a forgotten 5-year old bar of Castile made with 100% OO and a superfat of 5%, and darned if the lather didn't go all snotty on me the minute I lathered it up with my hands in the shower.
Normally, I use a nylon poufy thing to lather it with (which makes a decent, copious amount of lovely, decadent lather out of it), but I wanted to see how it did in my hand, with it being 5 years old and all.
Results? The lather turned out to be typically sparse with goop' a plenty, just the same as my much much younger Castiles.
When I put it back in the soap dish after lathering with it, it was like the soap didn't want to break connection with my hand, and it protested by producing long tendrils of egg white-like goopiness that stayed attached to me as I pulled my hand away from the dish.
I was able to stretch the goop out quite a long way before contact with my hand was finally broken, but the long tendrils of goop were still attached to the soap itself, and they hung down from it in the same way that saliva hangs down from a drooling dog's mouth. It was quite spectacular, really. lol
What was even funnier to me was that when my son took a shower later on during that same day, he accidentally grabbed my Castile (which had dried out by that time), instead of his own bar of soap (we each have our own bars of soap in the shower), and when he was done showering he came out of the bathroom and promptly proceeded to ask me what on earth kind of soap
that was, because it had practically no lather and was very goopy and slimy! Well, we're nothing if not completely honest at our house. lol I told him that's what he gets for not using his own bar of soap.
