Long-Lash™ Peptide Formulation Information

Based on the product information, here are the details regarding Long-Lash™ peptide:

• Main Components: Long-Lash™ contains Growth Complex Peptides: Myristoyl Pentapeptide-17 and Copper Tripeptide-1.
• Percentage: The recommended usage rate for Long-Lash™ in a formulation is 5-10%. The exact percentage of each individual peptide within the product is not specified in the available description.
• Mixing Method: Yes, Long-Lash™ should be added in the final step of your formulation. It is sensitive to heat, so you must avoid heat during the mixing process.
• Compatibility with Citric Acid: Do not include Citric Acid in a formula containing Long-Lash™. The product description explicitly states that AHA ingredients like Citric Acid act as chelating agents and will cause the Copper Tripeptide-1 component to lose its effectiveness.
• Compatibility with Sorbic Acid: Long-Lash™ contains Copper Tripeptide-1, which is sensitive to chelating agents and acids (as seen with the warning about Citric Acid). While Sorbic Acid is not an AHA, it is an acid often used to adjust pH or as a preservative. Using Sorbic Acid could potentially affect the stability or effectiveness of the Copper Tripeptide-1, especially if it significantly lowers the formula's pH or acts as a chelating agent in your specific formulation. It is recommended to carefully consider the purpose of adding Sorbic Acid and the final pH of the formula. If possible, test compatibility in a small batch or consult the supplier for specific compatibility data with Sorbic Acid.

For precise composition percentages and detailed technical documents regarding compatibility, it is best to contact customer service directly.
