Decanal dimethyl acetal

Decanal dimethyl acetal (CAS 7779-41-1 ), also known as 1,1-Dimethoxydecane and Decylaldehyde DMA, is a fragrance and flavoring ingredient used across personal care and food applications.

It functions as a protected aldehyde delivery form, releasing decanal's characteristic waxy, citrus-peel character under controlled conditions. In fragrance formulation, it offers improved stability over free decanal.

This stability in alkaline or reactive bases makes it preferred for soaps, detergents, and rinse-off personal care products where aldehydes degrade quickly. It is a versatile component for industrial use.

Food and beverage manufacturers use it as a FEMA 2363 -approved flavoring agent to impart fresh, fatty citrus notes in citrus flavor compositions, dairy products, and beverages.

Perfumers incorporate it into fine fragrance and functional fragrance bases where a cleaner, less volatile aldehyde profile is needed. It provides a sophisticated olfactory profile for various blends.

Its slower hydrolysis rate compared to the parent aldehyde also supports longer-lasting scent performance in leave-on cosmetic formulations. This ensures the fragrance remains consistent over time.

Decanal dimethyl acetal is supplied as a clear liquid. It is available in flavor and fragrance grades, with food-grade material conforming to regulatory specifications for use in flavor applications.

Typical commercial packaging ranges from small sample quantities through drum-scale supply for industrial formulators. This ensures flexible procurement options for manufacturers of all sizes.
