RUB A535

RUB A535 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand RUB A535 rather than just read about it. In short: RUB A535 (also known as Antiphlogistine) is a rubefacient introduced in 1919 and manufactured by Church & Dwight in Montreal, Quebec, Canada. While little known outside of Canada, it is used there for the treatment of tough muscle pain, arthritic pains, rheumatic pains, bursitis, lumbago, etc.

Key takeaways

  • RUB A535 belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect RUB A535 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of RUB A535 from memory before moving on to harder problems.

Reference excerpt

RUB A535 (also known as Antiphlogistine) is a rubefacient introduced in 1919 and manufactured by Church & Dwight in Montreal, Quebec, Canada.

While little known outside of Canada, it is used there for the treatment of tough muscle pain, arthritic pains, rheumatic pains, bursitis, lumbago, etc. Church and Dwight say on their website that nearly all the research, development and production of RUB A535 is carried out in Canada. Patients who are allergic to salicylates (ASA based drugs, such as aspirin), or who are taking anticoagulant medications should avoid the use of the product. It is also recommended to not use it more than 3–4 times a day.

Ingredients The active ingredients in RUB A535 are camphor, eucalyptus oil, menthol, and methyl salicylate. Some formulations also contain capsaicin and triethanolamine.

Varieties Currently, RUB A535 has been released in a variety of products:

Originally, it was produced in a particular white cream, carrying a rather offensive medical odour. Recently, the name was also given to a line of dual action back patches that change temperature (known as Hot-Cold patches). An improved cream was also developed, claiming to be odorless, differing from their normal cream, which carries the same smell as most topical analgesics. As of 2008, the "Ultra Heat" sport stick was released and shipped to many provinces, including Manitoba. It is sold as individual units containing 100 g of spearmint-smelling cream in packaging resembling an orange-coloured, slightly taller than usual deodorant stick. Like some deodorant sticks, the cream is dispensed by first uncapping the unit, then turning a dial at the bottom of the unit, thus pushing the cream up and out through three slits at the top. There is also a cold A535 named "Ice".

References in other disciplines Historically, the then local distributor was involved in a notable case in the High Court of Australia, about State income tax, Denver Chemical Manufacturing Company v The Commissioner of Taxation (New South Wales) (1949) 79 CLR 296. It simply involved a difference of views about how to disclose income on a tax return, but is the leading authority in its area.

Worked examples

Example 1 — a first encounter with RUB A535

Start with the simplest possible case. Write down what RUB A535 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 RUB A535 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 RUB A535 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 RUB A535

In research
RUB A535 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 RUB A535 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
RUB A535 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Analgesics, Church & Dwight brands, Goods manufactured in Canada, so understanding it makes those chapters shorter.
In everyday life
Look for RUB A535 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.

Frequently asked questions

What is RUB A535 in simple terms?

RUB A535 (also known as Antiphlogistine) is a rubefacient introduced in 1919 and manufactured by Church & Dwight in Montreal, Quebec, Canada. While little known outside of Canada, it is used there for the treatment of tough muscle pain, arthritic pains, rheumatic pains, bursitis, lumbago, etc.

Why does RUB A535 matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study RUB A535?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
