Reference excerpt

Murphy Oil Soap is an American brand of cleaning product that is manufactured by Colgate-Palmolive. In 1910, Jeremiah Murphy, director of the Phoenix Oil Company, bought the formula for Murphy Oil Soap from a recent immigrant from Germany. The soap, with its potassium vegetable oil base, and no phosphates, proved to be very popular in Ohio. The company continued to be run by the Murphy family for 80 years, when they sold it to Colgate. It is available in a concentrated liquid form which is then mixed with water, as well as pre-diluted form which comes in a trigger spray bottle. Commercials for the product state that the product is ideal for cleaning wood surfaces. The other constituents of Murphy Oil Soap are sodium EDTA, propylene glycol, fragrance, surfactants, and water.

Uses Murphy Oil Soap is commonly used to clean and polish horse tack, such as bridles and saddles. It is also commonly used to clean black-powder weapons after use, since the lack of petroleum-based oil and the presence of vegetable oil lessens the amount of sludge created when cleaning black powder residues from weapons. Murphy Oil Soap has been found to efficiently remove the residue that builds up on automobile wheels and hubcaps from the disc brakes. It is an excellent lubricant to use with water when throwing clay on a potter's wheel. Likewise the soap is often used as a release agent for plaster mold making. It has been found to quickly and easily dissolve water-based inks, such as Crayola marker ink, from acid-free paper. Murphy Oil Soap is also a favorite among artists as a brush cleaner. After removing excess oil paint from the brush with a rag and cleaning with a mineral spirit, the brush can be cleaned with a small amount of diluted soap. Diluted Murphy Oil Soap (2–4%) is often used by home gardeners as an insecticidal soap spray.

Worked examples

Example 1 — a first encounter with Murphy Oil Soap

Start with the simplest possible case. Write down what Murphy Oil Soap claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Murphy Oil Soap before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Murphy Oil Soap ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Murphy Oil Soap

In research: Murphy Oil Soap appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Murphy Oil Soap in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Murphy Oil Soap is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brand name products stubs, Cleaning products, Colgate-Palmolive brands, so understanding it makes those chapters shorter.
In everyday life: Look for Murphy Oil Soap outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
