17. Soaps & Detergents-
Soaps and detergents, like lipids, are
amphipathetic molecules with both
hydrophilic and hydrophobic properties.
The long hydrocarbon chains of soaps and
detergents are lipophilic, that is, these
chains are able to solubilize hydrocarbons
(remember, like dissolves like), while the
polar portion of the molecule provides
solubility in water.
Soaps are generally made from fats by a
process called saponification (sapon is
Latin for soap). Detergents are generally
synthetic compounds produced from
petroleum and their ionic ends are salts of
sulfonic acid, rather than carboxylic acids
(soaps). Soaps are more basic than
detergents and thus generally harsher.
Soaps and detergents work on oily
materials by dissolving their hydrocarbon
tails in the oils in a manner such that the
polar groups are facing outward into the
surrounding water forming micelles
around the oil.
