What breaks up oils and grease into small particles. Can be used to de-germ surfaces.
soaps
What is stronger than soaps, and may damage cell walls?
detergents
What is the most effective surface agent? Is used in mouthwash.
quaternary ammonium compounds
Name some quaternary ammonium compounds.
Bacteriostatic, fungicidal, amoebicidal
(EX): Aseptine, Cepacol
What is used as antimold agents in shampoos and cosmetics? or food preservatives.

Aldehydes
What are the two aldehydes?
formaldehyde, glutaraldehyde
What is a gas, is called formalin when dissolved in water?
- toxic carcinogenic
- preserves biological specimens and embalms people
- can sterilize but very slowly so is not good for any other purpose than those listed above.
formaldehyde
What is less toxic and less irritating, and is used to sterilize respiratory therapy equipment.
