Abstract
This invention relates to an aqueous gel comprising a specified capped polyether polymer and a surfactant. Preferred capped polyether polymers can be obtained by modifying a conventional polyether polyol with an alpha-olefin epoxide having an average of about 20 to 45 carbon atoms or mixtures thereof.
