Frequently Asked Questions

Q: What is the recommended concentration of the peptide blend for use in a leave-in scalp serum formulation?

A: For a leave-in scalp serum, the recommended concentration of the multi-peptide blend is typically between 2% and 5% of the total formulation weight. This range ensures sufficient bioactivity without causing viscosity issues or irritation. It is advisable to conduct a small-scale stability test at the target concentration to confirm compatibility with other ingredients, such as preservatives and humectants.

Q: How should the raw material be stored to maintain its peptide integrity during bulk logistics?

A: The raw material should be stored in airtight, light-resistant containers at a temperature below 25°C, away from direct sunlight and moisture. For long-term storage (over 6 months), refrigeration at 2-8°C is recommended to further slow any potential peptide degradation. Avoid repeated freeze-thaw cycles, as this can cause precipitation or loss of activity.

Q: What documentation is required for regulatory compliance when importing this peptide blend for cosmetic manufacturing?

A: For regulatory compliance, you will need a Certificate of Analysis (CoA) with HPLC purity data, a Material Safety Data Sheet (MSDS), and a certificate of origin. Additionally, if the product is to be used in EU or US markets, ensure the supplier provides EU CosIng compliance documentation or FDA 21 CFR Part 110 certification. Some regions may also require a heavy metal test report and a stability study summary.
