Fixed oils and fats have the same chemical composition: they consist chiefly of glycerides, resulting from a reaction between an alcohol called glycerol and certain members of a group of compounds known as fatty acids. Linseed, tung, and other drying oils ( i.e., those that are highly unsaturated) and large quantities of soybean, sunflower, and safflower oils are used in paints, varnishes, and alkyd resins. Considerable quantities of specialty oils and sulfonated oils are used in leather dressing and textile manufacture. Castor oil, for example, has a strong purgative action; fish-liver oils are sources of vitamins A and D; and others such as lard, olive oil, and almond oil serve as vehicles in pharmaceutical preparations. oil oil,
