The need for regulation and control for this group of poisonous chemicals is obvious. There has been some confusion as to the actual definitions of the various groups of biocides and there are still differences from one country to another. However, in the EEC, the Biocidal Products Directive (Directive 98/8/EC) was introduced as an instrument for regulation of current and new biocides. An important feature of this legislation is that the amount of a biocide used in a Formula t ion ChemicaIs 43 formulation must comply with the stated concentration for that particular biocide.

Hexane, a liquid hydrocarbon, is also non-polar with Van der Waals attractions between the molecules. When this liquid comes into contact with the wax surface there is an attraction between the molecules in the solid and the hexane molecules; this attraction is slightly stronger than the attractions existing in the pure substances and so the wax dissolves into the hexane. Polyethylene (Polythene), a hydrocarbon polymer, is chemically similar to paraffin wax, differing only in the lengths of its molecules, but it will not dissolve in hexane as does the wax.

6 Oxygenates are hydrocarbons containing oxygen in a variety of functional groups and represent a major category of solvents. Although most are synthesized from petroleum there is a signlJicant number from natural processes the troposphere and are thus prevented from reaching the higher altitude of the stratosphere where the ozone reactions occur. Other replacements for CFCs are the hydrofluorocarbons (HFCs). Fluorinated compounds such as the hydrofluoroethers, (HFEs) are finding use as solvents but their high cost restricts them to highly specialized work such as medical processes.
