DIETHYLHEXYL PHTHALATE
Commonly Found In
Overview
Diethylhexyl phthalate (DEHP) is the world's most widely produced plasticizer, primarily used in PVC manufacturing. It is banned in EU cosmetics (Annex II/677) as an endocrine disruptor and reproductive toxicant (CMR). DEHP is not a typical cosmetic ingredient β its cosmetic database listing reflects its presence as a contaminant or legacy use. It is subject to REACH restrictions in the EU and has been largely phased out of many applications globally due to reproductive and developmental toxicity concerns.
Also known as: DEHP, Diethylhexyl Phthalate, Di(2-ethylhexyl) Phthalate, DOP
Key Benefits
No skin benefits. DEHP is a plasticizer with no intended cosmetic skin benefit. It is a banned ingredient in EU/UK cosmetics.

Comedogenic Rating
Non-comedogenic; banned in EU cosmetics, so current cosmetic use is limited to non-EU markets or legacy formulas.

π Why Regulations Differ
The EU banned DEHP in cosmetics (Annex II/677) citing reproductive toxicity (CMR) and endocrine disruption; it is also restricted under REACH (Annex XIV) for most industrial uses in the EU. The US and Japan lack specific cosmetic bans but it has no cosmetic function. It is primarily relevant as a potential contaminant from packaging or equipment.

Strictness Ranking
πΏ Natural Sources
Not found in nature. Entirely synthetic compound, though it has become one of the most widespread environmental pollutants and can now be detected in almost all environments.
π How It's Made
Synthesized by esterification of phthalic anhydride with 2-ethylhexanol, typically using an acid catalyst. It's the most widely produced plasticizer in the world.
π Uses in Cosmetics
Used in cosmetic products primarily for fragrance, perfuming, plasticiser, solvent.
π¬ Other Applications
The world's most common plasticizer β used to make PVC flexible for items like shower curtains, garden hoses, flooring, food packaging, blood bags, and IV tubing. Being phased out in many applications due to health concerns.
π‘ Fun Facts
