What it is
A synthetic Schiff base compound produced by the condensation reaction of octanal (a fatty aldehyde) and methyl anthranilate (a natural ester found in grapes and citrus). It is used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
It functions solely as a fragrance ingredient, providing a sweet, floral, or citrus-like scent to products. It does not have any active skincare benefits like moisturizing or anti-aging; its only role is to improve the sensory experience of the product.
Pros

Low concentration needed
Effective at very low levels, so it's unlikely to cause issues for most users when used as intended.
Cons and cautions

No skincare benefit
Provides only fragrance; it does not moisturize, protect, or improve skin health in any way.
