Holy moly necro.
But a post got me curious, Kaolin Clay is usually a sign of an inferior product? Anybody care to elaborate if you think this is true?
I didn't know this was the case, I thought it was some sort of exotic skin moisturizing ingredient
Less knowledgeable soapmakers will add clay to a standard soap recipe and call it shaving soap. Clay improves slickness, but can't make up for an othewise insufficient formula. Clay is a drying agent. It has an ability to wick up oils as it dries, which is what you want in a mud mask, not so much in a shaving soap.
Very interesting. If I see this in a soap, is it safe to assume it's subpar? The artisan added it as a quick fix?
