Toilet Duck

Toilet Duck 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 Toilet Duck rather than just read about it. In short: Toilet Duck is an American brand name of toilet cleaner noted for the duck-shape of its bottle shaped to assist in dispensing the cleaner under the rim. The design was patented in 1980 by Düring AG from Dällikon, Switzerland.

Key takeaways

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

Reference excerpt

Toilet Duck is an American brand name of toilet cleaner noted for the duck-shape of its bottle shaped to assist in dispensing the cleaner under the rim. The design was patented in 1980 by Düring AG from Dällikon, Switzerland. It is now produced by S. C. Johnson & Son. The Toilet Duck brand can be found in the United States, United Kingdom and other countries around the world. In Germany, it is known as WC-Ente, previously produced by Henkel, and now by S. C. Johnson (Germany). In the Netherlands and Flanders it is called "Wc-eend", in France it is sold as "Canard-WC" and in Italy as "Anitra WC". In Hungary it used to have the name "Toalett Kacsa". Meanwhile, in Spain, it is sold as "Pato WC", in Portugal as "WC Pato", and in Mexico, Brazil, Colombia, Argentina and Chile as "Pato Purific" or simply "Pato". In Indonesia, it is one of the "Bebek" (duck) line of products, such as Bebek Kloset, Bebek Semerbak, Bebek Semerbak Flush, Bebek In Tank, and Bebek Kamar Mandi. The "Toilet" moniker has been dropped from the name in the UK and Ireland, and the product is now called "Duck". The same change is occurred in Hungary either, however also with the English "Duck" instead of "Kacsa". Today, the duck-shaped bottle is sold in North America under the Scrubbing Bubbles brand.

Ingredients The following ingredients are part of all Duck toilet-cleaning products:

L-lactic acid Water Ethoxylated alcohol Xanthan gum Sodium laureth sulfate Depending on variant, various dyes and fragrances are used, such as:

Liquid Marine: Liquitint Blue Dye, Liquitint Pink AL Dye, 2,6-dimethyl-7-octen-2-ol, 2-methoxy-4-propylphenol, 3,7-dimethyloct-6-enenitrile, coumarin, dipropylene glycol, eucalyptol, geraniol, isobornyl acetate, isobutyl salicylate, linalool. Liquid Citrus: Liquitint Orange 157, 2-t-butylcyclohexyl acetate, 3,7-dimethylnona-2,6-dienenitrile, allyl 3-cyclohexylpropionate, decanal, dipropylene glycol, ethyl 2-methylvalerate, gamma-undecalactone, methylbenzyl acetate, tricyclo(5.2.1.02,6)dec-4-en-8-yl acetate, triethyl citrate. Liquid Mint: Acid Blue 93, dipropylene glycol, mentha arvensis oil. Liquid Pine: Acid Blue #9, FD&C Yellow #5, 2,4-dimethyl-3-cyclohexene carboxaldehyde, 2,6-dimethyl-7-octen-2-ol, 2-methylundecanal, borneol, coumarin, dipropylene glycol, eucalyptol, isobornyl acetate, lauraldehyde, pogostemon cablin oil.

Advertising slogan In the Netherlands, the advertising slogan "Wij van Wc-eend adviseren Wc-eend" ("We, the people at Toilet Duck, recommend Toilet Duck") was used in a campaign that ended in 1996. Over 30 years later, the slogan is still being used as a general saying to dispute the independence of "expert" statements when they align with self-interest.

Fragrances Toilet Duck is available with a variety of fragrances. Fresh Action Gel is available in Garden Escape and Tropical Adventure scents. Deep Action Gel is available in Marine, Pine, Lavender, Mint and Citrus scents.

Worked examples

Example 1 — a first encounter with Toilet Duck

Start with the simplest possible case. Write down what Toilet Duck 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 Toilet Duck 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 Toilet Duck 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 Toilet Duck

In research: Toilet Duck 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 Toilet Duck 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: Toilet Duck is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cleaning products, S. C. Johnson & Son brands, Toilets, so understanding it makes those chapters shorter.
In everyday life: Look for Toilet Duck 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.
