Ingredients for 10L Batch (Vitamin C Anti-Aging Serum)

Dissolve Vitamin C in a small amount of distilled water first. Use pH-balanced (3.5-4.5) for stability. Pre-mix essential oils.

Step-by-Step Production Process

1. Preparation and Sanitization (20-30 minutes): Sanitize all equipment, bottles, and workspace with 70% alcohol. Measure ingredients precisely using a scale and graduated cylinders.
2. Prepare Water Phase (10-15 minutes): In a clean beaker, dissolve Vitamin C powder in distilled water or aloe vera gel. Heat gently to 40°C if needed, then add full aloe vera base. Stir until clear.
3. Blend Oil Phase (10 minutes): In a separate container, mix jojoba oil, rosehip oil, and vitamin E oil. Add preservative and essential oils. No heating required for anhydrous stability.
4. Emulsify and Mix (15-20 minutes): Slowly add oil phase to water phase while stirring vigorously (use a high-shear mixer for 10L). Blend for 5-10 minutes until uniform emulsion forms. Test pH and adjust if necessary.
5. Quality Check and Bottling (20-40 minutes): Let cool to room temp. Filter if needed, then fill sanitized dropper bottles. Cap securely.
6. Cooling and Storage (1-2 hours): Store in a cool, dark place. Label with date, ingredients, and "Shake before use."
7. Final Testing (10 minutes): Patch-test a sample for stability (no separation after 24 hours). Shelf life: 3-6 months refrigerated.

Total time: 1.5-3 hours active + settling. Use sterile techniques to prevent contamination.
