Valeraldehyde Hexyleneglycol Acetal
INCI: Valeraldehyde Hexyleneglycol Acetal
A synthetic fragrance ingredient that adds a fresh scent but offers no skincare benefits and may cause sensitivity in some people.
In plain English
This is a man-made chemical used to make products smell nice, often with a green or floral note. It doesn't moisturize, treat, or improve your skin in any way—it's purely for scent. Because it's a fragrance ingredient, it can sometimes cause irritation or allergic reactions, especially if you have sensitive skin.

What it is
Valeraldehyde Hexyleneglycol Acetal is a synthetic acetal compound created by reacting valeraldehyde (a type of aldehyde) with hexylene glycol. It is used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
It works by evaporating from the skin's surface, releasing scent molecules that are detected by your nose. It does not interact with the skin's biology or provide any functional benefit beyond fragrance.
Pros
Pleasant scent profile
Adds a fresh, green, or floral note that can enhance the sensory experience of using a product.
Low risk for most people
For those without fragrance sensitivities, this ingredient is generally well-tolerated at low concentrations.
Cons and cautions
No skin benefit
This ingredient does not hydrate, soothe, or improve skin health—it only provides scent.

Best for
- People who enjoy scented skincare and have no history of fragrance allergies
