Study Notes
Classifications of Shampoos
-
Anionic Surfactants: Commonly include sodium lauryl sulfate and sodium laureth sulfate.
- Sodium Lauryl Sulfate: Provides a harsh cleansing action and generates a rich foam, rinsing off easily.
- Sodium Laureth Sulfate: Offers a milder formula, less alkaline than lauryl sulfate, resulting in less dryness for the hair shaft.
-
Cationic Surfactants: Feature quaternary ammonium compounds.
- Known for their antibacterial properties, they are commonly found in dandruff shampoos.
-
Nonionic Surfactants: Include cocamide derivatives (DEA, MEA).
- Characterized by mild cleansing properties and a lower likelihood of causing irritation.
-
Amphoteric Surfactants: Generally categorized from 1 to 20.
- Their behavior shifts between anionic and cationic based on pH levels; they adhere to hair, enhancing manageability.
- Often nonstinging, making them suitable for use in baby shampoos.
