Manufacturing Procedure
- Weigh the Base: Accurately weigh the Silky Serum Base (498) into a clean, sanitized beaker.
- Add Actives: Weigh and add the active ingredients (Specialist B3 Serum, Galactomyces Ferment Filtrate, Repair Activator™ BG, and Mineral Ready™) one by one to the base.
- Mix: Stir gently but thoroughly until the mixture is completely homogenous and clear. Avoid excessive agitation to prevent foaming.
- pH Check & Adjustment: Measure the pH of the final serum. The target range is pH 5.0-6.0 for optimal stability and skin compatibility. If the pH is too high or too low, add a few drops of a pH adjuster (e.g., Lactic Acid to lower, Triethanolamine to raise) until the desired range is reached.
- Packaging: Transfer the finished serum into a clean, air-tight bottle (preferably an opaque or amber glass bottle to protect the ferments).
Important Considerations and Stability
- Texture: The Silky Serum Base is designed for a lightweight, non-sticky, and fast-absorbing finish, which meets the user's requirements.
- pH Stability: Niacinamide (in Specialist B3 Serum) is most stable at a pH of 5.0-6.0. The recommended pH range ensures the efficacy and stability of all active ingredients, especially the ferments (Galactomyces and Bifida).
- Preservation: The Silky Serum Base is already fully preserved. Adding the recommended percentages of water-based actives should not compromise the preservation system, provided the batch is made under clean conditions.
- Storage: Store the finished serum in a cool, dark place, away from direct sunlight and heat, to maintain the stability of the ferments and Niacinamide. The shelf life should be 6 months to 1 year.
- Patch Test: Always advise the user to perform a patch test before full use, especially since the formula contains high levels of active ingredients.
- Note: The Specialist B3 Serum (127411) is a pre-made serum containing a high concentration of Niacinamide. Adding 15% of this product will result in a potent final concentration of Niacinamide in the finished serum.*
