Part 1 — Why Handmade Cold Process Soap Sometimes “Sweats”

If you’ve ever picked up a bar of handmade cold process soap and noticed tiny beads of moisture on the surface during humid weather, don’t worry — your soap is not going bad.

In fact, it’s often a sign of one of the best parts of real handmade soap: natural glycerin.

During the cold process soapmaking method, oils and lye go through a chemical reaction called saponification. As the soap forms, natural glycerin is created naturally within the bar.

In many commercial soaps and detergents, that glycerin is removed and sold separately for use in lotions, creams, and cosmetics. But in true handcrafted cold process soap, the glycerin stays right where it belongs.

Why does that matter?

Glycerin is a natural humectant, which means it attracts moisture to the skin and from the air around it. That’s one reason handmade soap often feels gentler and more moisturizing compared to heavily processed commercial bars.

The downside?

In humid climates — especially during warm Arkansas summers — that same glycerin can pull moisture from the air and create little droplets or a slightly damp feeling on the soap’s surface. Soapmakers often call this “glycerin dew” or “soap sweat.”

It is completely harmless and does not affect the quality of the soap.

Many of us who make soap by hand actually see it as a reminder that the bar still contains its naturally occurring glycerin — one of the things that makes handcrafted soap so special.

Real handmade soap behaves differently because it is made differently.

Slowly crafted.
Small batch.
Naturally rich.
Made with intention.

That’s the beauty of cold process soap.
