What it is

A synthetic ester formed from 2-methylpentanol and 2-methylvaleric acid, used as a fragrance ingredient in cosmetics and personal care products.

How it works

It evaporates from the skin's surface, releasing a pleasant scent. It does not interact with the skin's biology or provide any functional skincare benefit beyond fragrance.

Pros

Low irritation potential at low levels

Cons and cautions

No skincare benefit

This ingredient only provides fragrance; it does not hydrate, soothe, or improve skin health.

Potential allergen

Like many fragrance ingredients, it can trigger contact dermatitis or allergic reactions in sensitive individuals.

Best for

  • People who enjoy scented skincare products
  • Those without fragrance sensitivities

Use caution if

  • Individuals with sensitive, reactive, or eczema-prone skin

Usage tips

If you have sensitive skin, patch test a scented product before full-face application.
