Why Is My Soap Sweating or Weeping?

Short answer: beads on soap are usually one of two things. Clear, watery beads that show up in humid weather are glycerin dew, also called sweating. Oily beads that smell strongly of fragrance usually mean too much fragrance, or fragrance that wasn't fully mixed in. Wrap bars against humidity, and weigh your fragrance.

Glycerin dew (sweating)

Glycerin pulls water out of the air. On humid days, it can bead up on the surface of your bars like dew.

• Melt and pour sweats the most, because the base has extra glycerin.
• Cold process can sweat too, especially in a humid room or after time in the fridge.
• The beads feel wet, not oily, and don't smell much stronger than the bar.

What helps:

• Let bars cool and harden at room temperature.
• Wrap melt and pour bars tightly in plastic wrap as soon as they're cool.
• A fan or dehumidifier in your soap room helps in moderate humidity.
• Store wrapped bars in an airtight container.

Fragrance weeping

Oily beads that smell strongly of fragrance mean the soap couldn't hold all of it.

• Too much fragrance. Over about 6% of your oil weight in cold process, or 3% of the base in melt and pour.
• Not fully mixed in. Fragrance added at a thick trace, or stirred in too little.
• Separation in the pot. If the batter didn't fully come together, fragrance can work its way out later. See Why Did My Soap Rice or Separate?

What helps next time: weigh your fragrance and use our fragrance calculator, add it early, and mix it in well. Never go over the fragrance's IFRA limit for soap.

A safety note

If clear droplets show up on cold process soap in the first day or two, and the soap feels slick or stings your skin, it may be lye that didn't mix in. Wear gloves, don't use the soap, and check your recipe in our soap calculator.
