Are Phthalates Harmful in Skincare and Cosmetics?

Q: Are phthalates harmful in skincare and cosmetics?

Phthalates can disrupt hormone systems, leading to potential health issues. They mimic or block hormones, causing imbalances.

⚡ Quick Answer: Phthalates are chemicals used in some cosmetics and fragrances that can act as endocrine (hormone) disruptors. The amount in any single product is small, but because we're exposed from many sources, many people choose to limit them. To avoid them, look for "phthalate-free," choose fragrance-free or transparently scented products, and watch for "fragrance/parfum," DEP, DBP and DEHP on labels. Switching to water-free, synthetic-fragrance-free formulas like CallNature's SD7 Lipid Serum (skin) and Dental Pro 7 (gums) is one easy way to sidestep hidden phthalates.

Phthalates are one of the most-asked-about "ingredients to avoid" in skincare. The honest answer is nuanced: they're not an acute danger in any one product, but there are good reasons to reduce your overall exposure. Here's what they are, what the concern actually is, and how to avoid them.

What are phthalates and why are they in cosmetics?

Phthalates are a family of chemicals used as plasticisers (to make materials flexible) and, in cosmetics, mainly to hold fragrance and help products spread. They commonly hide inside the catch-all label term "fragrance" or "parfum," which is exactly why they're so easy to miss — a single "fragrance" entry can legally contain dozens of undisclosed components, phthalates among them.

Are phthalates actually harmful?

The concern is that some phthalates can act as endocrine disruptors — they can interfere with the body's hormone signalling. Research has linked higher exposure to effects on reproductive and developmental health, and they can be absorbed through the skin. Two points of balance:

The dose in a single cosmetic is small, and regulators in the UK and EU restrict the most concerning phthalates in cosmetics.
The bigger issue is cumulative exposure from many products and sources over time, which is why reducing avoidable exposure is sensible — especially during pregnancy.

How do I avoid phthalates in my skincare?

Look for "phthalate-free" on the label.
Be cautious of "fragrance" or "parfum," which can conceal them — choose fragrance-free products, or brands that disclose their scent ingredients (for example, products scented only with named botanicals).
Scan for the abbreviations DEP, DBP and DEHP in ingredient lists.
Favour transparent brands that publish full ingredient information.
Consider water-free formulas. Anhydrous products are typically simpler, with fewer of the synthetic additives that carry phthalates.
