Soap that contains iron atoms could find use in oil spill clean-ups and in waste water treatments.
Although it's similar to hand soap, the 'magnetic soap' is different from what we use on a daily basis in one key way - it contains iron atoms. The detergent part of the soap attracts the oil (or any dirt) and when a powerful magnet is applied, the water is removed magnetically along with any absorbed oil.
An international team of scientists has demonstrated the first soap that responds to magnets. This means the soap and the materials that it dissolves can be removed easily by applying a magnetic field. Experts say that with further development, it could find applications in cleaning up oil spills and waste water.
