Ethyl Formate is a solvent and fragrance ingredient that can add a fruity scent but may cause irritation in sensitive individuals at higher levels.
In plain English

What it is
Ethyl Formate is an ester formed from ethanol and formic acid. It occurs naturally in some fruits and is also produced synthetically for use as a solvent and flavor/fragrance agent.
How it works
In cosmetics, Ethyl Formate acts primarily as a solvent to help blend other ingredients and as a fragrance component to impart a sweet, fruity scent. It evaporates quickly, contributing to the sensory feel of a product.
Pros

Adds a natural-smelling fruity note (like rum or raspberry) that can make the product more enjoyable to use.
Effective solvent
Helps dissolve other ingredients, ensuring a smooth and stable formula.
Cons and cautions
