Does Ivory soap float?

Normally, we’re not particularly keen on brand-name products, but this is a phenomenon that has been perpetuated since Ivory soap was first marketed in 1879, and until recently, the reasons for floating Ivory soap were a closely held secret.

The soap floats because the manufacturers intentionally whip a small amount of air into the soap as it’s being made. This makes the soap lighter than water, so it floats. The formula, perfected in 1878, was discovered after a worker at the factory where Ivory Soap was produced accidentally left the soap-making machine running as he stopped for a lunch break. When he returned, he found that air had been worked into the mixture. The soap was later poured into molds and marketed as such.

Proctor and Gamble, capitalizing on the fact that their soap is lighter than water, added the slogan “It Floats” to the soap in 1891.
