    2021-7-5 · Surfactants are compounds used in an array of cleaning products for their ability to lower the surface tension of water, in essence making the molecules slipperier, so they are less likely to stick to themselves and more likely to interact with oil and grease. Beyond soaps and detergents, surfactants are used in lubricants, inks, anti-fogging ...
