Question
I would like to ask if it is possible to mix `Ectoin` into the `Moisturizing Lotion Base (Compare to Cetaphil)`. If it is possible, could you please provide a recommended formula for this mixture?
Answer
You can definitely mix Ectoine (Ectoin, from Bio-fermentation) into the Moisturizing Lotion Base (Compare to Cetaphil). Ectoin is a highly stable, water-soluble active ingredient that works well within a wide pH range (1-9), making it perfectly compatible with this lotion base.
However, since the Moisturizing Lotion Base (Compare to Cetaphil) is a preservative-free base, it is essential to add a preservative when you open the container to mix in additional ingredients to ensure the product remains safe for use.
Recommended Formula (Total 100g)
- Moisturizing Lotion Base (Compare to Cetaphil): 97% (97g)
- Ectoine (Ectoin, from Bio-fermentation): 2% (2g)
- Mild Preserved™ COS (Preservative): 1% (1g)
Mixing Instructions
- Preparation: Ensure all mixing tools and containers are clean and sanitized with 70% alcohol.
- Weighing: Weigh the Moisturizing Lotion Base into a mixing container.
- Adding Actives: Add the Ectoine powder directly into the base. Stir continuously until the powder is completely dissolved and the texture is smooth. (Ectoin is water-soluble and will dissolve into the water phase of the lotion).
- Preservation: Add Mild Preserved™ COS and stir thoroughly to ensure the preservative is evenly distributed.
- Packaging: Transfer the finished lotion into a clean, airtight bottle or jar.
Additional Tips
- Ectoin Concentration: 2% is the recommended usage rate for optimal skin protection, anti-pollution, and hydration benefits.
- Dissolving: Because the base is already thickened, it may take a few minutes of stirring to ensure the Ectoin powder is fully dissolved without leaving any graininess.
- Storage: Store the finished product in a cool, dry place away from direct sunlight.
