Surf (detergent)

Surf (detergent) 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 Surf (detergent) rather than just read about it. In short: Surf (known as Sunil in the Netherlands) is a British brand of laundry detergent manufactured and marketed around the world by Unilever, except in the United States, Canada and Puerto Rico, where it has been owned by Sun Products (now Henkel North American Consumer Goods) since 2008. The brand was introduced in 1952 by Crosfields of Warrington, a subsidiary company of Lever Brothers in the United Kingdom.

Key takeaways

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

Reference excerpt

Surf (known as Sunil in the Netherlands) is a British brand of laundry detergent manufactured and marketed around the world by Unilever, except in the United States, Canada and Puerto Rico, where it has been owned by Sun Products (now Henkel North American Consumer Goods) since 2008. The brand was introduced in 1952 by Crosfields of Warrington, a subsidiary company of Lever Brothers in the United Kingdom. Surf was introduced in the United States in 1959 after Rinso, which had been Lever Brothers Company's lead laundry brand, had declined in sales and market share. Between 1994 and 2001, Birds of a Feather stars Pauline Quirke and Linda Robson appeared in a series of adverts which saw them in a variety of different scenarios. In 1998, January Isaac played Lumen in their 'Wais' commercials series in the Philippines; other characters were Lola Obang (Nina Medina) and her son Lando (Nap Miranda) and their twins Ana and Maria (played by Charice and Charlotte Hermoso from 2004 to 2007). Present in the Brazilian market since 2003, soap powder is currently sold in the following fragrances: Rosas and Flor de Lis; Hydrangeas and White Flowers; Passion Flower and Daisy; and Cherry Blossom and Lavender. It is also available in the form of liquid soap, in the version Jasmine do Oriente and Flor de Lotus. The Tablet version (Bar) was no longer manufactured in July 2010. In Portugal and the UK, the powder is currently marketed with the "Tropical Lilies & Ylang Ylang" fragrances. In both countries it is also available in pre-dosed "capsules".

Worked examples

Example 1 — a first encounter with Surf (detergent)

Start with the simplest possible case. Write down what Surf (detergent) 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 Surf (detergent) 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 Surf (detergent) 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 Surf (detergent)

In research: Surf (detergent) 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 Surf (detergent) 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: Surf (detergent) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brand name products stubs, British brands, Cleaning product brands, so understanding it makes those chapters shorter.
In everyday life: Look for Surf (detergent) 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.
