Aldehyde C-12 Lauric, also known as Dodecanal (CAS# 112-54-9), is a long-chain aliphatic aldehyde with very high odor impact and strong diffusion. It is a classic material in the aliphatic aldehyde family, widely used to bring a sparkling, “lifted” effect and to brighten the overall character of fine fragrances as well as functional fragrance compositions.
The odor profile of Aldehyde C-12 Lauric is dry, citrusy and clean, reminiscent of lemon and citrus peels, with a characteristic fatty–waxy aldehydic nuance, a slight metallic edge and a touch of green freshness. At low dosages it gives a pronounced soapy, “just-showered” cleanliness, enhancing the diffusion and radiance of floral, citrus and marine/ozonic accords.
In formulation, Aldehyde C-12 Lauric is commonly used in aldehydic florals (rose, jasmine, muguet), citrus colognes, clean/soapy fragrances, marine and ozonic creations, as well as in modern laundry and household care fragrances. It is a key ingredient in perfumes for detergents, fabric softeners, surface cleaners and air care products, where even very small amounts can deliver a bright, sharp cleanliness and strong lift on fabric and in the air.
Physically, Aldehyde C-12 Lauric is a colorless to pale yellow liquid, sparingly soluble in water but readily soluble in alcohol, perfume oils and most fragrance solvents. It should be stored tightly closed, away from heat and light to minimize oxidation and preserve its fresh, crisp character and stability during storage and use in fragrance formulations.
