Ingredient review
Amyl Butyrate
INCI: Amyl Butyrate
Amyl Butyrate adds a sweet, fruity scent to products but offers no skincare benefits; it's generally safe at low levels but may cause irritation in sensitive individuals.
In plain English
Amyl Butyrate is a man-made chemical that smells like apples or pineapple. It's added to lotions, perfumes, and soaps to make them smell nice. It doesn't moisturize, treat, or improve your skin in any way—it's purely for fragrance. Most people can use it without problems, but if your skin is very sensitive or you have a fragrance allergy, it might cause redness or itching.
