Alkyl dimethyl benzyl ammonium chloride: toxicity to Coniophora puteana when formulated in water and organic solvent
1986 - IRG/WP 2250
Results from agar block tests using Coniophora puteana demonstrate that the biological activity of alkyl dimethyl benzyl ammonium chloride is affected by the nature of the carrier solvent in which it is applied. In contrast to some earlier work, an alkyl ammonium compound in organic solvent formulation was identified that had significantly greater activity than its aqueous equivalent. A simple sol...

Influence of weathering of wood surfaces before and after treatment with iron(II) sulphate
2023 - IRG/WP 23-30786
Outdoor wood is exposed to various factors that cause the wood to grey or age. The ageing processes can vary greatly depending on the exposure. Parts of the wood that are not exposed to external factors, e.g. under the eaves, are less exposed and the ageing process is therefore slower. This can be accelerated by solutions based on iron ions. In this way, the wood greys quickly and evenly. However,...
