Abstract
A cleansing composition is disclosed that changes color during use. The cleansing composition contains a plurality of thermochromic dyes that cause a color change to occur at a threshold temperature and continue to cause a color change over a temperature range. The range of temperatures corresponds to approximately the amount of time sufficient to properly wash or scrub using the product.
