Face serum is prepared by combining an oily phase with an aqueous (water-based) phase through a mixing process.
Here's a breakdown based on the provided reference:
Preparing the Oily Phase
- The oily components, including olive oil, sandalwood oil, Tween 20, and coconut oil, are mixed together.
- This mixture is stirred for approximately 10 minutes until a completely uniform solution is achieved.
Preparing the Aqueous (Water-Based) Phase
- The water phase is made by combining aloe vera gel, glycerin, and a small amount of distilled water.
- These ingredients are mixed thoroughly until the mixture is uniform.
Combining the Phases
Once both the oily and aqueous phases are prepared separately, they would be combined to form a serum. The method of combining them and further processing is not in the provided reference. This may involve slow addition, emulsification, and further mixing.
| Component | Phase | Purpose |
|---|---|---|
| Olive oil | Oily | Moisturizer, antioxidant |
| Sandalwood oil | Oily | Fragrance, soothing |
| Tween 20 | Oily | Emulsifier, helps mix oil and water-based ingredients |
| Coconut oil | Oily | Moisturizer |
| Aloe vera gel | Aqueous | Soothing, moisturizing |
| Glycerin | Aqueous | Humectant, attracts moisture to the skin |
| Distilled water | Aqueous | Solvent |
Summary
The process involves separately preparing an oily and aqueous phase and then mixing them together to create a serum. The provided reference details the ingredients and preparation of each phase before combination.
