Surfactant Types

• Anionic: Principal and main ingredients of shampoo
• Non-ionic: Co-surfactant, foam booster, rheology modifier, viscosity inducer, stabilizer, solubilizer.
• Amphoteric: Impart mildness to shampoo, minimize burning sensation in eyes.
• Cationic: Not use in shampoos

Surfactant Function

• Surfactants enhance solubility of compounds not soluble in water
• Enable water and oil to mix
• Surface active agent that reduces surface tension, increasing spreading and wetting properties

Solubility

• Citric acid: 1 in less than 1 part of water
• Cocamidopropyl betaine (30%): Surfactant
• Dimethicone copolyol: Immiscible with water, >30.8 µg/mL

Emulsifying Properties

• PEG-3 distearate: Emulsifying, 25- 35% aqueous solution, clear liquid with a mild odor
• Other components: Water soluble, emulsifiers/surfactants soluble in water at room temperature

Manufacturing Procedure (Method B)

• Step 1: Weigh all ingredients
• Step 2: Dissolve SLS in water
• Step 3: Add Cocamidopropyl betaine (30%) with stirring
• Step 4: Add remaining ingredients except citric acid and NaCl
• Step 5: Add deionized water to make 100ml
• Step 6: Filter the mixture
• Step 7: pH Adjustment: Add citric acid and adjust pH to 5.6 to 6.2
• Step 8: Viscosity Adjustment: Add NaCl by continuous stirring until desired viscosity is achieved
• Step 9: Pack and label in appropriate container

Quality Control Tests

• Physical Appearance: Color, clarity, odor, texture
• pH: Measure using a pH meter
• Rheology (Viscosity): Brookfield viscometer
• Foaming ability & Stability: Check volume of foam formed and remaining (after 20 minutes)
• Dirt Dispersion: India ink test tube
• Wetting time: Draves Test Method
• % Solids: Evaporating dish
• Surface Tension: Using 10% shampoo at room temperature, formula provided
• Stability Study
• Microbiology test
• Evaluation of safety: Skin and eye toxicity

Specification or Limits

• pH range: 5.0 - 7.0
• Rheology (viscosity): 9,593.67 to 910 Centipoise (CPS)
• Foam ability: 100ml or more
• Dirt dispersion: None or no distribution ink in foam
• Wetting time: Shorter time, means max concentration of detergent at different storage conditions
• Solids: 20-30%
• Surface tension: 72.28 dyn/cm to 40 dyn/cm
• Stability: Shelf life is 3 years unopened, and 18 months if opened
