Ueda, Naomi published the artcileImprovement of conservation for waterlogged woods using polyethylene glycol (PEG) (treatment with cationic surfactants), Recommanded Product: Dodecylamineacetate, the publication is Zairyo (1992), 41(461), 148-52, database is CAplus.
In the conventional polyethylene glycol (I) method for conservation of waterlogged wood, it is sometimes difficult for I to penetrate into the wood, depending on wood species or the degree of deterioration, and shrinkage (e.g., maximum 20 ? 30% in tangential direction) or warp of specimens occurs. In order to maintain its dimensions and mech. strength, Akagashi (Quercus?acuta?Thunb.) wood was treated with some cationic surfactants which were easily adsorbed on cellulose and thus lowered surface tension of water. With the surfactant treatment it was expected that possible shrinkage accompanied by water evaporation could be decreased. The wood samples were soaked in a dilute cationic surfactant solution, followed by immersion in I solution with gradual increase of its concentration The variations of dimension and weight were monitored periodically. The surfactant treatment allowed I to penetrate easily into waterlogged wood. Furthermore, it was noticed that the shrinkage and change in shape could be minimized, and the dimensions were maintained without any significant change. In addition, by using the present treatment, one can expect that the penetration time in PEG treatment will be shortened.
