Semi-aqueous cleaners
Semi-aqueous cleaners are a group of cleaning solutions composed of natural or synthetic organic solvents, surfactants,
rust inhibitors and other additives. The term semi-aqueous refers to the use of water in some part of the cleaning
process, such as washing, rinsing, or both. In general, they have a good ability to remove heavy grease, waxes and
tar. Their low surface tension allows them to penetrate small spaces. Some also have low vapor pressure and thus
have low volatile organic compound (VOC) emissions. Depending on the type of cleaner, adverse effects will vary;
some may be toxic to aquatic life, others are highly flammable or need rinsing and drying.
Semi-aqueous cleaners can be a mixture of water and hydrocarbons, which require both a rinsing and drying step in
the cleaning process. Common semi-aqueous cleaners may include terpenes, esters, glycol ethers, and N-methyl-2-pyrolidine
(NMP) and other hydrocarbons.
