Why does Ivory soap expand in the microwave?
In the case of Ivory, it has a bit of extra air whipped into the soap mixture. This is why it floats in the bath tub. When soap is microwaved, the air trapped inside of the soap heats up and starts to expand. The water inside the soap also heats up and will turn to steam.

What happens when you put bar soap in the microwave?
When soap is microwaved, the air trapped inside of the soap heats up and starts to expand. The water inside the soap also heats up and will turn to steam. As the gases grow in volume, they push on the remaining soap ingredients, expanding the bar from something small and compact to a fluffy blob.
What is different about Ivory soap that allows it to expand when heated?
In the case of Ivory, it has a bit of extra air whipped into the soap mixture. The soap expands due to Charles’s Law, named for the scientist who is credited with the calculations to explain what happens to gases when heated. This law explains that when a gas is heated, its volume expands.
