L-Carnitine: Formulation Compatibility, Exfoliation, and pH Adjustment

Hello,

Regarding your questions about L-Carnitine:

1. Can L-Carnitine be combined with ingredients like "slim coffee" (10% for cellulite) and almond oil in the same product?
   Yes, they can be combined and are suitable for use together as they complement each other's functions. The pH of the formula can be in the range of approximately 4-5.

2. Can L-Carnitine exfoliate, reduce "chicken skin" (keratosis pilaris), and treat underarms?
   L-Carnitine does have some exfoliating properties, but its effect is not as strong as direct exfoliating agents like AHA or BHA. For "chicken skin," BHA is the most suitable ingredient.

Regarding your follow-up question:

3. Can L-Carnitine be mixed directly with water containing Disodium EDTA? Is the pH low enough?
   Yes, it can be mixed directly with water or water + Disodium EDTA. However, if the formula only contains these ingredients, it is recommended to add an acid such as Citric Acid or Lactic Acid to adjust the pH to the range of 5-6, which is more suitable for the skin.

Thank you.
