In plain English

This ingredient is a man-made compound that helps absorb ultraviolet (UV) light, protecting your skin from sun damage. It is created by combining two other chemicals—amylcinnamal (a fragrance allergen) and methyl anthranilate (a UV absorber). Because it contains a known fragrance allergen, it can sometimes cause skin irritation or allergic reactions, especially in people with sensitive skin.

Score terms in plain English

Irritation risk

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

What it is

A synthetic Schiff base formed by the condensation of amylcinnamal (a fragrance allergen) and methyl anthranilate (a UV-absorbing compound). It functions primarily as a UV filter in sunscreens and also contributes to the product's scent.

How it works

It absorbs UV radiation, particularly in the UVA and UVB range, and converts it into harmless heat, preventing it from damaging skin cells. Additionally, its fragrance component can mask other odors in the formula.

Pros

Effective UV absorber

Helps protect skin from both UVA and UVB rays, reducing the risk of sunburn and long-term damage.

Formula stabilizer

Can improve the stability and efficacy of other sunscreen ingredients in the formulation.

Cons and cautions

Fragrance allergen risk

Contains amylcinnamal, a common allergen that can trigger skin reactions like redness, itching, or rash in sensitive individuals.

Potential irritation

May cause stinging or irritation, especially on already sensitive or compromised skin.

Best for

  • People looking for effective UV protection in sunscreens
  • Those without known fragrance allergies

Use caution if

  • Individuals with sensitive skin or a history of fragrance allergies

Usage tips

Patch test before using a product containing this ingredient, especially if you have sensitive skin.
Use in conjunction with other sun protection measures like hats and shade for best results.

Safety summary

Generally considered safe for most people when used as directed, but poses a moderate risk of skin irritation and allergic reactions due to its fragrance allergen component. Avoid if you have known sensitivities to fragrances.

Research notes

Studies confirm its UV-absorbing properties, but research on long-term safety and environmental impact is limited. Allergenicity of amylcinnamal is well-documented.
