A cleaning agent made from fats and alkali, used for washing and cleaning. A substance that removes dirt and grease through chemical action.
From Old English 'sape,' possibly from Germanic roots related to 'sap' (tree resin). The earliest soaps were made from plant and animal fats combined with ash, creating the first surfactants.
Soap is essentially organized chemistry - its molecules have one end that loves water and another that loves oil, making it the perfect mediator between the two. Ancient peoples discovered this miracle by accident when fat drippings mixed with wood ash created the first crude soaps.
Soap and domestic cleaning products were heavily marketed to women from 1920s onward; advertising reinforced women's unpaid domestic labor as natural and gendered.
Use neutrally; recognize that household product marketing historically enforced gendered divisions of unpaid domestic work.
Women in soap manufacturing and chemistry (e.g., chemists who formulated products) had their contributions erased; domesticity was emphasized over scientific innovation.
