Adding Phenoxyethanol to Syn-Ake for Pre-preservation
คำถาม
Since Syn-ake does not contain any preservatives, I am concerned that adding it to a skincare base might result in an inadequate preservation system. I have noticed that most of the skincare products I use contain Phenoxyethanol as a preservative.
- Is it possible to add
Phenoxyethanoldirectly into theSyn-akesolution before incorporating it into a skincare formulation? - What is the recommended concentration (%) to ensure the ingredient remains effective and safe for use?
คำตอบ
Yes, you can add Phenoxyethanol to Syn-Ake (Dipeptide Diaminobutyroyl Benzylamide Diacetate). Phenoxyethanol is not on the list of restricted preservatives for this peptide and is generally compatible with it.
Recommendations for Use
Usage Percentage:
- For Pre-preservation: If you want to add it directly to the Syn-Ake liquid to ensure it stays preserved before use, you can add Phenoxyethanol (Extra Pure) at 1% by weight.
- In the Final Formula: Ensure that the total concentration of Phenoxyethanol in your final skincare product does not exceed 1.0% (which is the standard safety limit).
Important Precautions for Syn-Ake:
To ensure the peptide remains effective, please follow these guidelines:- Avoid these preservatives: Do not use Syn-Ake with Potassium Sorbate, Benzyl Alcohol, Dehydroacetic Acid, or any preservatives in the Urea group (such as Diazolidinyl Urea).
- Avoid these ingredients: Do not use it in formulas containing Propylene Glycol, PEG-40 Hydrogenated Castor Oil, Sodium Metabisulfite, or Disodium Cocoamphodiacetate.
- Optimal pH: The formula should have a pH between 3.5 and 6.5.
- Temperature: While it can withstand some heat, it is best added during the cooling phase (below 40°C) to ensure maximum stability.
Recommended Preservative:
We recommend using Phenoxyethanol (Extra Pure) because it has a very low level of impurities, reducing the risk of skin irritation compared to standard grades.
By following these steps, you can safely enhance the preservation of your Syn-Ake solution without compromising its anti-wrinkle performance.
