Ethylhexyl Methoxycinnamate

Ethylhexyl Methoxycinnamate is a widely used organic (chemical) UV filter that primarily absorbs UVB radiation, protecting the skin from sunburn and sun damage. It is often combined with other UV filters to provide broad-spectrum protection. While effective, there have been some discussions regarding its potential environmental impact and systemic absorption.

BenefitGood 2.5 / 4

Uv protection i3.5 / 4

Whether it provides direct protection against UV radiation.

RiskHigh 2.5 / 4

Systemic exposure i2.5 / 4

Whether it has meaningful potential to be absorbed into the body at levels that may matter biologically. Most cosmetic ingredients score low unless there is known concern or high exposure.

Endocrine i2.5 / 4

Whether it has known or suspected hormone-related activity or endocrine-disruption concern.

Reproductive i2 / 4

Whether there are known or plausible concerns for pregnancy, fertility, fetal development, or breastfeeding.

Sensitization i1 / 4

Risk of allergic contact dermatitis or immune-based reactions. Fragrance allergens, preservatives, botanicals, and some dyes may score here.

Eye irritation i1 / 4

Whether it may sting or irritate around the eyes. Relevant for sunscreens, fragrances, acids, surfactants, and volatile ingredients.

Irritation i1 / 4

Risk of short-term irritation — stinging, burning, dryness, redness, or discomfort. Common for strong actives, acids, retinoids, fragrances, and harsh surfactants.

Frequently asked questions

What is Ethylhexyl Methoxycinnamate and how does it protect skin?

Ethylhexyl Methoxycinnamate is a chemical sunscreen filter that absorbs harmful UVB rays from the sun. It works by converting UV radiation into heat, preventing it from damaging skin cells and causing sunburn.

Are there any concerns about using Ethylhexyl Methoxycinnamate?

Some studies suggest potential for systemic absorption and possible endocrine disruption, though regulatory bodies generally consider it safe for use in approved concentrations. There are also environmental concerns regarding its impact on marine ecosystems.
