Oleyl alcohol

Oleyl alcohol is a chemistry 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 Oleyl alcohol rather than just read about it. In short: Oleyl alcohol , or cis-9-octadecen-1-ol, is an unsaturated fatty alcohol with the molecular formula C18H36O or the condensed structural formula CH3(CH2)7−CH=CH−(CH2)8OH. It is a colorless oil, mainly used in cosmetics.

Key takeaways

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

Reference excerpt

Oleyl alcohol , or cis-9-octadecen-1-ol, is an unsaturated fatty alcohol with the molecular formula C18H36O or the condensed structural formula CH3(CH2)7−CH=CH−(CH2)8OH. It is a colorless oil, mainly used in cosmetics. It can be produced by the hydrogenation of oleic acid esters by Bouveault–Blanc reduction, which avoids reduction of the C=C group (as would occur with usual catalytic hydrogenation). The required oleate esters are obtained from beef fat, fish oil, and, in particular, olive oil (from which it gains its name). The original procedure was reported by Louis Bouveault in 1904 and subsequently refined. It has uses as a nonionic surfactant, emulsifier, emollient and thickener in skin creams, lotions and many other cosmetic products including shampoos and hair conditioners. It has also been investigated as a carrier for delivering medications through the skin or mucous membranes; particularly the lungs.

Worked examples

Example 1 — a first encounter with Oleyl alcohol

Start with the simplest possible case. Write down what Oleyl alcohol claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Oleyl alcohol 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 Oleyl alcohol 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 Oleyl alcohol

In research: Oleyl alcohol appears in chemistry 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 Oleyl alcohol 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: Oleyl alcohol is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alkenols, Cosmetics chemicals, Fatty alcohols, so understanding it makes those chapters shorter.
In everyday life: Look for Oleyl alcohol 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.
