White Fibrous Streaks with Long-Lash™ at 5%

Regarding the white fibrous streaks observed when using Long-Lash™ at a 5% concentration, this is not a typical characteristic of the ingredient. Long-Lash™ is normally a clear liquid.

The appearance of white fibrous streaks suggests a potential issue with the formulation, likely due to incompatibility with other ingredients or the overall conditions of the mixture.

Possible causes include:

• Incompatibility with other ingredients: Long-Lash™ contains Copper Tripeptide-1. The product description specifically advises against using chelating agents like Disodium EDTA or AHAs (such as Lactic Acid, Glycolic Acid, Citric Acid) in the formula, as they can bind to copper ions and reduce the effectiveness of the Copper Peptide. These types of interactions can sometimes lead to precipitation or instability, appearing as fibrous material.
• Incorrect pH: The recommended pH range for formulations containing Long-Lash™ is 3.5-5.5. If the final pH of your formulation falls outside this range, it could affect the stability and solubility of the ingredients, potentially causing precipitation.
• Mixing Method: While the description states to mix in the water phase and avoid heat, ensure the mixing process is appropriate for all ingredients in your specific formula.

Regarding whether the ingredient is spoiled, while improper storage (it should be stored in a cool place at 6-8 degrees Celsius) could potentially affect the ingredient over time, the formation of white fibrous streaks is more commonly a sign of a formulation or compatibility issue rather than typical microbial spoilage or degradation.

To troubleshoot, review your formulation's ingredients for potential incompatibilities (especially chelating agents or ingredients sensitive to copper), check the final pH of your mixture, and ensure the mixing process is correct.
