Often loosely listed as “fragrance” on product labels, phthalates are used to enhance absorption, make fragrances last longer and as gelling agents in some shampoos.
Studies show that they may pose such dangers as insulin resistance in adolescence, interference with the hormone system, infertility, weight gain, higher risk of liver cancer among others.
In as much phthalates are harmful; they are not exactly illegal, and manufacturers don’t have to list them as their ingredients because fragrance is considered proprietary by law. This leaves us a bit in the dark.
You want your hair smelling nice, but you also do NOT want to end up with complications.
Thus, look out for ingredient names like; DnHP (di-n-hexyl phthalate), DNOP (di-n-octyl phthalate), DBP (dibutyl phthalate), BzBP (benzylbutyl phthalate), DCP (dibutyl phthalates), DMP (dimethyl phthalate), etc.
