alkyl sulfate
hydrophilic group
Hydrophobic group
molecules that contain positively charged heads
Cationic detergents
Cationic detergents characteristics
Long, non-polar tail and a cationic head
Long, non-polar tail and a cationic head e.g.
tertiary ammonium ion (R–N(CH3) 3+)
Used in
plastic cleaners, hair conditioners and fabric softeners, disinfectants, and antiseptics.
do not contain an ionic charged head. They usually contain heads that are partially charged
Non-ionic detergents
Non-ionic detergents characteristics
Long, non-polar tail but a polar head that is not ionically charged
Long, non-polar tail but a polar head that is not ionically charged. For example,
alcohol (hydroxyl) and/or ether (ethoxy) functional groups.
Non-ionic detergents Typically used in
front-loading washing machines and dishwashers.
hydrogen bonds form with surrounding molecules
Soaps and detergents share similar structure as their structures consist of a
hydrophobic tail and a hydrophilic head.
Soaps and detergents are both
surfactants
Soaps and detergents are both surfactants as their structures allow them to reduce tension between oil and water by forming
micelles
vary between soaps and the three types of detergents
Hydrophilic heads
- Detergents are (blank) whereas soaps are produced from (blank) such as vegetable oils and animal fats.
synthetic, biomass
Although both are cleaning agents, detergents and soaps have different
uses
An organic compound found in various natural sources.
