Is Ethylene Glycol Dimethacrylate safe in cosmetics?
Ethylene Glycol Dimethacrylate is rated high risk in cosmetic products. It is a known allergen that can cause contact dermatitis in sensitized individuals.
What is Ethylene Glycol Dimethacrylate?
Ethylene Glycol Dimethacrylate (EGDMA) is a bifunctional acrylate monomer used as a cross-linking agent in nail products, dental adhesives, and certain cosmetic formulations. It belongs to the acrylate/methacrylate family and is one of the most potent sensitizers in this chemical class. EGDMA is primarily found in gel nail systems, UV-cured nail polishes, and artificial nail products. When properly cured, it poses minimal risk, but uncured or partially cured EGDMA can penetrate the nail plate and cause sensitization. Once sensitized, even trace exposures can trigger allergic contact dermatitis. Its bifunctional nature (two reactive ends) makes it particularly aggressive in causing cross-sensitization to other acrylates.
Allergy & Safety Information
EGDMA is classified as a strong allergen and skin sensitizer. It is a known occupational hazard for nail technicians. The EU Cosmetics Regulation restricts its use in nail products. Patch testing with EGDMA 2% in petrolatum is recommended for suspected acrylate allergies. Cross-reactivity with HEMA, methyl methacrylate, and other acrylates is common. If sensitized, avoidance of all acrylate-containing products is advised. Symptoms include redness, itching, swelling, and blistering at the exposure site, often affecting fingertips, nail folds, and surrounding skin.
This ingredient is classified as high risk from an allergenicity perspective. It is a recognised cause of allergic contact dermatitis with a relatively high sensitisation rate in patch-tested populations. People with a history of skin reactions to cosmetics, or with conditions such as eczema or sensitive skin, should exercise particular caution.
About Acrylate Ingredients
Acrylates are used in nail products (gel nails, nail polishes, adhesives), eyelash adhesives, and some hair styling products. They form durable films upon curing (typically via UV light). Acrylate allergy has become more common with the rise of gel nail systems and is a recognised occupational hazard for nail technicians.
Relevance for Ethylene Glycol Dimethacrylate: HEMA (2-hydroxyethyl methacrylate) is the most common acrylate allergen in gel nail systems. Cross-reactivity between different acrylates is common — a reaction to one often predicts sensitivity to others in the group. Acrylate sensitisation can make dental work and medical adhesives problematic.
How to Identify Ethylene Glycol Dimethacrylate in Products
Cosmetic ingredients are listed by their INCI (International Nomenclature of Cosmetic Ingredients) name in descending order of concentration. To check whether a product contains Ethylene Glycol Dimethacrylate, scan the ingredient list for its INCI name exactly as it appears above. Ingredients present at 1% or less may appear in any order after the 1% threshold.

Frequently Asked Questions
What products contain Ethylene Glycol Dimethacrylate?
EGDMA is found in gel nail polishes, UV/LED nail systems, artificial nail kits, some dental adhesives, and industrial adhesive products.
Can I use nail products if I am allergic to EGDMA?
If you have a confirmed EGDMA allergy, you should avoid all gel nail and acrylate-based nail products. Traditional solvent-based nail polishes without acrylates are generally safe alternatives.
How is EGDMA allergy diagnosed?
EGDMA allergy is diagnosed through patch testing by a dermatologist or allergist, typically using the acrylate series patch test panel.
Is EGDMA banned in cosmetics?
EGDMA is not outright banned but is subject to restrictions in cosmetic products under EU regulations. Its concentration is limited and products must meet safety standards.
What are the symptoms of EGDMA allergy?
Symptoms include itching, redness, swelling, and blistering around the nails and fingertips. In severe cases, the reaction can spread to the eyelids and face from touching.
