Chemical & Engineering News

When it comes to cleaning, ethoxylated fatty alcohols are the good stuff, beating conventional soap in cleaning power while being gentle on skin and clothes.

As is the case with soap, this structural motif lets them play the intermediary between greasy substances and watery ones, binding emulsions together in a lipstick or helping a dish detergent wash away butter.
