Personal Care Formulation Process
1. Dissolution Sequence
-
Polymers (e.g., HPMC, HEC): Disperse in cold water first, then dissolve by heating or pH adjustment to prevent clumping.
-
Carbomers: Must be dispersed in water first, then neutralized with a base (e.g., TEA) to thicken.
-
Powder Thickeners (e.g., Xanthan Gum): Sprinkle slowly into water under high-speed stirring to prevent agglomeration.
2. pH Control
-
Carbomers: Optimal pH 6-9.
-
Acrylic Emulsions: Best clarity at pH 5-7.
-
Cellulose Derivatives (e.g., CMC-Na): Stable within pH 5-9.
3. Salt Dosage
-
-
Typical dosage 0.5-2%. Excess can cause “salting out” and thinning. Recommended to add incrementally while checking viscosity.
-
4. Electrolyte Tolerance
- For high-salt systems (e.g., laundry liquid), use salt-tolerant thickeners such as salt-resistant polyacrylic acids or bio-based composite gums.
5. Skin Feel and Clarity
-
Refreshing Gel: Options include HEC, Carbomer.
-
High Clarity: Options include Carbomer, Acrylic Emulsions, HEC.
