Manufacturing Protocol (Lab-Scale)
Phase A – Aqueous Base
- Heat water phase to 75°C.
- Dissolve Glycerin, EDTA, and Sodium Polyacrylate under gentle stirring.
- Hydrate carbomer and adjust pH to neutral (6.0–6.5) if needed.
Phase B – Oil Phase
- In separate vessel, melt Liquid Paraffin, silicones, esters, and emulsifiers at 75°C.
- Mix until homogeneous.
Emulsification
- Slowly add oil phase (B) into water phase (A) under high shear mixing (3000 rpm).
- Maintain temperature at 70–75°C for 10 minutes.
Phase C – Cooling and Actives
- Cool batch to 40°C.
- Add humectants, Hyaluronic Acid, Urea, and Allantoin.
- Mix thoroughly to avoid clumping.
Phase D – Final Additions
- Cool to <35°C.
- Add preservatives, perfume, colorants.
- Homogenize and adjust pH (target 5.5 – 6.0).
- Check viscosity and texture.

| Freeze–Thaw | -5°C/25°C (3 cycles) | Post test | No separation/crystallization |
Packaging Recommendations
- Jar or pump tubes with high-barrier materials (e.g., PP, HDPE).
- UV-resistant packaging to protect actives like Vitamin E and hyaluronic acid.
- Airless pump systems recommended to reduce contamination risk.
- Clearly label with INCI list, expiry date, directions, safety warnings.
