Chapter 26: Problem 33

Identify some of the detergents used in shampoos and dish-washing liquids. Are they primarily anionic, neutral, or cationic detergents?

Short Answer

Expert verified
Answer: Most common detergents used in shampoos and dish-washing liquids are anionic detergents. Some examples include Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES), Ammonium Lauryl Sulfate (ALS), Sodium Cocoyl Isethionate, and Sodium Lauroyl Sarcosinate.

Step by step solution

01

Identify common detergents in shampoos and dish-washing liquids

Here are some common detergents found in shampoos and dish-washing liquids: 1. Sodium Lauryl Sulfate (SLS) 2. Sodium Laureth Sulfate (SLES) 3. Ammonium Lauryl Sulfate (ALS) 4. Cocamidopropyl Betaine 5. Lauryl Glucoside 6. Sodium Cocoyl Isethionate 7. Sodium Lauroyl Sarcosinate
02

Classify detergents into anionic, neutral, or cationic categories

1. Sodium Lauryl Sulfate (SLS) - Anionic 2. Sodium Laureth Sulfate (SLES) - Anionic 3. Ammonium Lauryl Sulfate (ALS) - Anionic 4. Cocamidopropyl Betaine - Amphoteric (can act as both anionic and cationic) 5. Lauryl Glucoside - Nonionic 6. Sodium Cocoyl Isethionate - Anionic 7. Sodium Lauroyl Sarcosinate - Anionic
03

Conclusion

Most common detergents used in shampoos and dish-washing liquids are anionic detergents such as Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES), Ammonium Lauryl Sulfate (ALS), Sodium Cocoyl Isethionate, and Sodium Lauroyl Sarcosinate. One exception is Lauryl Glucoside, which is a nonionic detergent, and Cocamidopropyl Betaine, which is an amphoteric detergent (acting as both anionic and cationic).

Draw the structural formula of a lecithin containing one molecule each of palmitic acid and linoleic acid.

Phospholipids, the second most abundant group of naturally occurring lipids, are derived from phosphatidic acids, compounds containing glycerol esterified with two molecules of fatty acid and a molecule of phosphoric acid. \- Further esterification of the phosphoric acid part with a low-molecular- weight alcohol, most commonly ethanolamine, choline, serine, or inositol, gives a phospholipid.

Triglycerides rich in saturated fatty acids are generally solids or semisolids at room temperature and are called fats.
