For your preservatives, it would be much cheaper to purchase piroctone olamine and phenoxyethanol and mix them by yourself.

Because to make LGN, the ratio should be 1:1 to 1:6 high HLB:low HLB surfactants in mole.

I think Xanthan Gum and Panthenol is less than 1% in first formula so your surfactant should be ≤1% too.

You need all of them. Add EDTA, reduce pH to at least 4.7 and increase benzoate to 0.5%.

Thank

This product claims that it removes calcium from hair.

Is pH 2.8 because citric acid chelates calcium better at that pH? Or because at pH 2.8 hair has positive charge?

And that glycine is 29th ingredient on LOI.

What confused me is that in their website they say it has 3% citric acid and at LOI citric acid is 12th ingredient even after fragrance.

Can it be that 3% citric acid is not in this product and in another product?
