. Distinguish between Soap and detergent
- Soap refers to the sodium or potassium salt of long chain fatty acids (Stearic acid, Palmitic acid).
- Detergent refers to the sodium or potassium salt of a long alkyl chain terminating with a sulfonate group.
- Soaps are insoluble in hard water as they generate insoluble Calcium and Magnesium soaps.
- Hard water comprises Calcium and Magnesium ions.
- Detergents can be used in soft as well as hard water as they produce foam in hard water.
- Laundry soaps include fillers like(borax, sodium carbonate, and sodium rosinate).
- Anionic detergents are used for household purposes.
- Liquid dishwash are non-ionic detergents.
- Medicated soaps have substances with medicinal properties.
- Cationic detergent has a germicidal property.
- Cationic detergent (Cetyltrimethylammonium bromide) used in hair conditioners.
Hence, soaps are salts of long chain fatty acids and detergents are sulphonated long chain alcohols or hydrocarbons.
