Which detergents are also used in toothpaste?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Anionic detergents.
Toothpastes commonly contain anionic detergents, the most notable being Sodium Lauryl Sulfate (SLS). Anionic detergents have negatively charged ions, which help in foaming, cleansing, and even dispersion of the toothpaste during brushing. These detergents loosen and remove food particles, plaque, and debris from the teeth and gums. Their foaming action also enhances the perception of cleanliness. While effective, anionic detergents like SLS can sometimes cause mouth irritation in sensitive individuals. In such cases, alternatives like non-ionic or mild surfactants are used. Overall, anionic detergents play a crucial role in improving oral hygiene through effective cleaning action.
Other Options:
-
Synthetic detergents: This is a broad category that includes anionic, cationic, and non-ionic detergents, so it’s not specific.
-
Non-ionic detergents: Less commonly used in toothpaste due to lower foaming properties.
-
Cationic detergents: Generally not used in toothpaste because they can be toxic and have antimicrobial but irritating effects.
