| cetacea | An order of wholly aquatic mammals occurring in all the oceans and adjoining seas of the world, as well as in certain river systems. Some cetaceans are the only animals other than elephants that have a brain larger than man's. most have eyes well adapted to underwater vision and can also see well above water. They produce numerous underwater sounds used in echolocation. They feed generally on fish, cephalopods, and crustaceans. Most are gregarious and most have a relatively long period of parental care and maturation. (12 Dec 1998) |

| cetrimonium compounds | Cetyltrimethylammonium compounds that have cationic detergent, antiseptic, and disinfectant activities. They are used in pharmaceuticals, foods, and cosmetics as preservatives; on skin, mucous membranes, etc., as antiseptics or cleansers, and also as emulsifiers. These compounds are toxic when used orally due to neuromuscular blockade. (12 Dec 1998) |
| cetyl | The univalent radical C16H33-of cetyl alcohol. (05 Mar 2000) |
| cetyl alcohol | The 16-carbon alcohol corresponding to palmitic acid, so called because it is isolated from among the hydrolysis products of spermaceti; it is used as an emulsifying aid and in the preparation of "washable" ointment bases. Synonym: 1-hexadecanol, palmityl alcohol. (05 Mar 2000) |
