Abstract
Polyhydroxyl and polyether hydroxyl esters of fatty acids and polyether hydroxides are provided as waterproofers. These waterproofers are also combined with quaternary ammonium compositions and a solvent in waterproofing, wood preservative systems. Preferred quaternary ammonium compounds have chloride, hydroxide, carbonate, carboxylate, or borate counter ions.
