Don't use tallow soap if you're fond of soap-dish slime.
Most bars dissolve into a sad sliver and a puddle within a week. This one won't give you that closure.
Tallow's stearic and palmitic acids make a genuinely hard bar. It lathers clean and stays a bar, no mush in the dish.
Soap is supposed to be temporary. It softens, it slumps into the dish, it shrinks to a sliver and slides down the drain, and the cycle starts again. There’s a rhythm to it. Tallow soap has no respect for that rhythm.
Tallow is dense with stearic and palmitic acid, the fatty acids that make a bar genuinely hard. It lathers clean, no synthetic surfactants, then it just stays a bar. No slime in the dish. No disintegrating sliver. No puddle. It sits there, solid and useful, for far longer than you’d like.
Deeply inconvenient, if you were attached to watching soap die.
