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

Pleasant scent profile

Adds a sweet, floral-citrus aroma that many people find appealing, enhancing the user experience.

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

Potential irritant

Can cause skin irritation, redness, or allergic reactions in people with sensitive skin or fragrance sensitivities.

No skincare benefit

Provides only fragrance; it does not moisturize, protect, or improve skin health in any way.

Best for

  • People who enjoy scented products and have no history of fragrance allergies
  • Those looking for a synthetic alternative to natural essential oils

Use caution if

  • Individuals with known fragrance allergies or sensitive skin
  • Anyone preferring fragrance-free or hypoallergenic products

Usage tips

Patch test any new product containing this ingredient on a small area of skin before full use.
If you have sensitive skin or eczema, choose fragrance-free products to avoid potential irritation.

Safety summary

Generally recognized as safe for most people when used at low concentrations in cosmetics. However, it can cause skin irritation or allergic reactions in sensitive individuals. The International Fragrance Association (IFRA) sets usage limits to minimize risk.

Research notes

Limited peer-reviewed studies specifically on this Schiff base, but related fragrance ingredients have been evaluated for safety by expert panels. Evidence suggests low acute toxicity but potential for skin sensitization.
