Propylene glycol in cosmetics at the top of the ingredient list means that its concentration is quite high. Indeed, without it, none of the elements will be able to penetrate deep into the skin. Therefore, the cosmetic product will become useless.
The permissible content of this additive in the composition of cosmetic products is not more than 10%.
