Disodium EDTA vs. IPM for Skin Penetration
Question
Can Disodium EDTA be used as a penetration enhancer in a body lotion, similar to or instead of IPM? What ingredients are suitable for skin penetration?
Answer
Disodium EDTA vs. IPM for Skin Penetration
Disodium EDTA cannot be used in place of IPM (Isopropyl Myristate) to help with skin penetration in a body lotion. They have completely different functions in a formulation.
Disodium EDTA is primarily a chelating agent. Its main role is to bind with metal ions in water to prevent them from interfering with the stability and performance of the product. It does not enhance the absorption of other ingredients into the skin.
IPM (Isopropyl Myristate) is an emollient and a spreading agent. While it can help the lotion feel less greasy and spread more easily on the skin, its primary function is not to actively carry other ingredients into the skin layers.
If you are looking for ingredients to enhance the penetration of active substances into the skin, you should use dedicated penetration enhancers. Examples include:
- Laurocapram (Water Soluble): Suitable for enhancing the penetration of water-soluble active ingredients.
- Laurocapram (Oil Soluble): Suitable for enhancing the penetration of oil-soluble active ingredients.
Choose the appropriate type of penetration enhancer based on the solubility of the active ingredients you want to deliver into the skin.
