Micro-emulsions for Removal of Waxes and Oils from Artefact Surfaces

Popis výsledku v původním jazyce

One of the most important and sometimes even dangerous steps of the conservation intervention is removal of undesirable substances - such as corrosion products, sedimentary impurities or previously used preserving or consolidating agents from the historical objects. It mainly concerns polymer substances. These substances are hardly removable. Some of them are insoluble after crosslinking etc. Organic solvents are commonly used for these purposes, but they can cause risk for conservator health and environment. New dispersion systems - micro-emulsions of organic solvents in water in the presence of suitable surfactant - seem to be very useful agents for this purpose. These dispersion systems are highly recommended because of a low content of organic solvents. The poster discusses cleaning efficiency of such systems for wax and oil from different substrates. Two types of waxes (paraffin, beeswax) and two types of oils (standard and polymerized linseed oil) were tested. The tested micro-em
