Why doesn't my handmade soap make huge foam?

Big, fluffy foam feels like a sign of a good clean. But foam and cleansing aren't the same thing.

Lather comes mostly from the oils in a soap. Coconut and castor oil make bigger bubbles, while olive oil and butters make a smaller, creamier lather. Bars with clay or charcoal can feel less bubbly too. Many mass-made cleansers add foaming agents to create that rich-foam effect.

What actually cleans your skin is the soap itself. Each soap molecule holds on to water at one end and oil at the other, so it lifts away oil and dirt for water to rinse off. A gentle, creamy lather does this just as well.

Your water also plays a part. Hard water, common in many Indian cities, makes most soaps lather less.

A few tips: work the bar between wet palms for a few seconds before applying, or use a loofah or soap pouch. And if you love more bubbles, try a bar with a "Rich" lather, such as Eucalyptus + Kaolin Clay or Volcanic Sand + Bergamot.
