It depends on which phthalate — some, like DEHP, are restricted or banned in cosmetics due to genuine health concerns, while others still permitted within current regulations are used mainly as fixatives to help scent last longer, and this remains a genuinely disputed area rather than a settled one.

Why it’s not a simple yes or no

Phthalates have historically been used in some fragrance formulations to help scent molecules bind and last longer on skin. Certain types have been restricted or banned in the EU and UK due to evidence linking them to health concerns, while others that are still legally permitted continue to be debated by researchers and consumer groups. Many brands have moved away from phthalates altogether in response to this ongoing concern, even in cases where a specific ingredient remains legally allowed, which has made ‘phthalate-free’ a common label on newer releases.

  • Some phthalates are already restricted or banned in UK/EU cosmetics
  • Others remain permitted but continue to be debated by researchers
  • ‘Phthalate-free’ labelling is increasingly common regardless of current legal status

As with parabens, checking a specific product’s ingredient listing or looking for a phthalate-free claim is the most reliable way to make an informed choice if this is a genuine concern for you.
