Infobox references

Dodecanol /ˈdoʊˈdɛkɑːnɒl/, or lauryl alcohol, is an organic compound produced industrially from palm kernel oil or coconut oil. It is a fatty alcohol. Sulfate esters of lauryl alcohol, especially sodium lauryl sulfate, are very widely used as surfactants. Sodium lauryl sulfate, ammonium lauryl sulfate, and sodium laureth sulfate are all used in shampoos. Lauryl alcohol is tasteless and colorless with a floral odor.

Production and use


In 1993, the European demand of dodecanol was around 60 thousand tons per year (Tt/a).[citation needed] It can be obtained from palm kernel or coconut oil fatty acids and methyl esters by hydrogenation.[3] It may also be produced synthetically via the Ziegler process.


Dodecanol is used to make surfactants, lubricating oils, pharmaceuticals, in the formation of monolithic polymers and as a flavor enhancing food additive. In cosmetics, dodecanol is used as an emollient. It is also the precursor to dodecanal, an important fragrance.



Toxicity


Dodecanol can irritate the skin. It has about half the toxicity of ethanol, but it is very harmful to marine organisms.[4]



Mutual solubility with water


The mutual solubility of 1-dodecanol and water has been quantified as follows.[5]

Westermarck effect

This article includes a list of references, but its sources remain unclear because it has insufficient inline citations . Please help to improve this article by introducing more precise citations. (November 2014) (Learn how and when to remove this template message) The Westermarck effect , or reverse sexual imprinting, is a hypothetical psychological effect through which people who live in close domestic proximity during the first few years of their lives become desensitized to sexual attraction. This phenomenon was first hypothesized by Finnish anthropologist Edvard Westermarck in his book The History of Human Marriage (1891) as one explanation for the incest taboo. Observations interpreted as evidence for the Westermarck effect have since been made in many places and cultures, including in the Israeli kibbutz system, and the Chinese Shim-pua marriage customs, as well as in biologically-related families. In the case of the Israeli kibbutzim (collective farms), children...
