Ingredient Compatibility: Disodium EDTA with Copper Peptide and other ingredients
Question
I understand that Disodium EDTA is not compatible with Copper Peptide because EDTA chelates the Copper Peptide, reducing its effectiveness.
Could you please confirm if this understanding is correct? Also, I would like to know the compatibility of Disodium EDTA with the following ingredients:
- Copper Peptide (GHK-Cu)
- Long-Lash™
- WaterLock™
- Pure Keratin™
If Disodium EDTA is added to a formula containing Copper Peptide, will it indeed cause the Copper Peptide to lose effectiveness by being chelated by EDTA?
Answer
Ingredient Compatibility with Disodium EDTA
Based on the information, Disodium EDTA is a chelating agent that can bind with metal ions. This property makes it incompatible with ingredients containing Copper Peptide, such as Copper Peptide (GHK-Cu) and Long-Lash™.
Disodium EDTA and Long-Lash™: Long-Lash™ contains Copper Tripeptide-1, which is a type of Copper Peptide. Disodium EDTA will chelate the copper ions in Copper Tripeptide-1, reducing the effectiveness of Long-Lash™. Therefore, Disodium EDTA should not be used in formulations containing Long-Lash™.
Disodium EDTA and WaterLock™: WaterLock™ (Polyquaternium-51) is compatible with Disodium EDTA.
Disodium EDTA and Pure Keratin™: Pure Keratin™ (Hydrolyzed Keratin) is compatible with Disodium EDTA.
In summary, avoid combining Disodium EDTA with Long-Lash™ or any other ingredient containing Copper Peptide to maintain their efficacy. Disodium EDTA can be used with WaterLock™ and Pure Keratin™.
