The shampoos contain palmitic acid. But this acid is usually derived from palm oil. Is that the case with your shampoos ?
The fact that the word "palmitic" contains the word "palm" can lead to some confusion! It gives the impression that it comes from palm oil. But in this case, it has nothing to do with palms. Palmitic acid is a fatty acid, and the "palm" simply indicates that it has a carbon chain of 16 carbon atoms.
It's used as a thickening agent that helps to hold our products together and make them last. Palmitic acid can be obtained from many plants, and ours is derived from olives.
