Water Based Degreaser

What are Water Based Degreasers?

A Water based degreaser utilize water as the primary solvent. It remove soils not only by dissolving contaminants, but can also chemically react with the greasy contaminants and make them more readily dissolvable in water. The combination of water, solvents, surfactants, and saponifiers in a water based degreaser can be safer than solvents and often more effective at cutting through hardened on grease.

Solvent Degreasers versus Water Based Degreasers

In order to really understand the advantages of today’s water based degreasers, it is necessary to have some understanding of the traditional solvent based process.

Solvent degreasing is the process where grease, oil, wax and other surface contaminants are removed from work pieces. They typically use organic solvents (such as trichloroethylene and Kerosene). Solvent degreasing is commonly carried out in metal working industries, and especially in garages and the automotive and related industries. Usually applied when cleaning things like engines and other mechanical parts that get covered in. Most degreasing solvents are, to a greater or lesser extent, harmful to health and therefore require some form of control measures to minimise or eliminate the risk to the user.

The Health Risks are numerous:

Strict guidelines have to be followed when using solvent based degreasers, and equipment has to be carefully designed to minimise the risk to the user. All degreasing tanks should be fitted with covers and have some form of extraction. If degreasing is carried out by hand, such as by using a rag or hand spray, adequate ventilation needs to be provided. PPE such as gloves, goggles or face shields and respirators are required, and an emergency shower and eye bath has to be available.

With recent restrictions on the purchase and use of solvents such as Trichloroethylene and Methylene Chloride there has been a move towards the development of safer, environmentally friendly degreasers.
