| No Harsh Toxins Removed from every ECHí formula | No Irritants Removed from every ECHí formula |
|---|---|
|
Formaldehyde
A known human carcinogen that causes nail brittleness, allergic reactions, and respiratory irritation with repeated exposure.
|
Ammonia
A corrosive irritant that damages the nail plate, causes skin burns, and irritates the airways even at low concentrations.
|
|
Formaldehyde Resin
A derivative of formaldehyde that frequently causes allergic contact dermatitis and sensitisation of the skin surrounding the nail.
|
Xylene
A solvent linked to headaches, dizziness, and nervous system damage with regular inhalation during nail application.
|
|
Toluene
A powerful neurotoxic solvent responsible for that sharp chemical smell; causes headaches, dizziness, and can harm foetal development in pregnancy.
|
Phenoxyethanol
A preservative that can irritate sensitive skin, cause allergic reactions, and is particularly concerning for use around infants and during pregnancy.
|
|
Dibutyl Phthalate (DBP)
An endocrine-disrupting plasticiser linked to hormonal imbalance, reproductive harm, and foetal developmental issues in pregnant women.
|
Phthalates
A class of hormone-disrupting chemicals that can impair reproductive health and have been detected in blood and urine after nail polish use.
|
|
Camphor
Can cause nail discolouration and yellowing, and in large doses triggers nausea, dizziness, and seizures through skin absorption.
|
Triclosan
An antimicrobial chemical linked to antibiotic resistance, endocrine disruption, and environmental contamination; banned in several countries.
|
|
Ethyl Tosylamide
Banned in EU cosmetics due to its antibiotic properties, which contribute to antimicrobial resistance — a serious global health concern.
|
Sodium Lauryl Sulfate (SLS)
A harsh surfactant that strips the nail's natural oils, causes skin irritation, and weakens the nail plate with regular use.
|
|
Triphenyl Phosphate (TPHP)
An endocrine disruptor that absorbs through the nail into the bloodstream, detected in urine within hours of nail polish application.
|
Glycol Ethers
Solvents linked to bone marrow damage, anaemia, and reproductive harm; they penetrate skin readily and accumulate with repeated exposure.
|
|
Parabens
Preservatives that mimic oestrogen and have been detected in breast tissue; linked to hormonal disruption and potential cancer risk with long-term exposure.
|
Peracetic Acid
A strongly corrosive oxidiser that irritates and burns skin, eyes, and airways — damaging the nail bed and surrounding cuticle tissue.
|
|
Butylphenyl Methylpropional
A synthetic fragrance chemical restricted in the EU due to its role as a known skin sensitiser and potential endocrine disruptor.
|
4-Methylbenzylidene Camphor
A UV filter with strong hormone-disrupting activity that absorbs through skin and has been found in human breast milk.
|
|
Tert-Butyl Hydroperoxide
A harsh oxidising agent that causes nail brittleness, skin irritation, and is classified as a potential mutagen with repeated exposure.
|
Ethylhexyl Methoxycinnamate
A chemical UV absorber that disrupts thyroid hormones, penetrates the bloodstream, and has been detected in human breast milk.
|
|
Oxybenzone
A UV filter and potent endocrine disruptor that penetrates deep into skin, disrupts oestrogen levels, and is linked to allergic reactions.
|
Harsh Synthetic Fragrances
Proprietary chemical blends that frequently contain hidden allergens, neurotoxins, and endocrine disruptors not disclosed on ingredient labels.
