Hydrocinnamyl Formate
INCI: Hydrocinnamyl Formate
A synthetic fragrance ingredient that adds a sweet, floral scent but offers no skincare benefit and may cause sensitivity in some individuals.
In plain English
Hydrocinnamyl Formate is a man-made chemical added to products to give them a pleasant, sweet, floral smell. It doesn't moisturize, treat, or improve your skin in any way—it's purely for scent. While generally considered safe at low levels, it can be a potential irritant for people with sensitive skin or fragrance allergies.

What it is
Hydrocinnamyl Formate is a synthetic ester derived from cinnamyl alcohol and formic acid. It is used exclusively as a fragrance ingredient in cosmetics, perfumes, and personal care items.
How it works
In a cosmetic product, Hydrocinnamyl Formate contributes to the overall scent profile. It evaporates from the skin's surface, releasing its fragrance. It does not interact with the skin's biology or provide any functional benefit beyond scent.

Provides a sweet, floral aroma that can enhance the sensory experience of using a product.
Low Irritation for Most
At typical low concentrations, it is generally non-irritating for people without fragrance sensitivities.
Cons and cautions
No Skincare Benefit

Best for
- People who enjoy scented products and have no history of fragrance sensitivity
