Aldehyde C-10 (Decanal) opens with ripe citrus—orange peel, waxy-candied brightness, clean and slightly lactonic—projecting strongly at the top before drying down to a smooth, warm, beeswax nuance. This luminous, soapy, and pristine note unlocks the top structure while extending citrus radiance into the heart.

In formulas, Decanal boosts freshness in orange, lemon, and grapefruit themes; enriches aldehydic-floral (jasmine, rose, muguet), soap, detergent, “fresh laundry,” and candle accords. It pairs effectively with Aldehyde C-11/C-12, Linalool, Limonene, Citral, Hedione, Hydroxycitronellal, Orange oil, Neroli, and Petitgrain to achieve sparkle and a refined classic aldehydic character.

Highly potent—use sparingly: typically 0.02–0.3% in fine fragrance; 0.05–0.5% in home and air care depending on the desired diffusion. Even a trace can “light up” an entire composition; higher dosages emphasize the waxy/soapy effect. Always test on blotter and in the target base to finalize the optimal level.

It shows good stability in most solvent systems and dissolves well in ethanol, DPG, TEC, and common fragrance bases. Evaluate compatibility in products with strong acidity or alkalinity. Consider adding a trace antioxidant if the formula is terpene-rich (e.g., citrus-heavy).

Applications include perfumes, body mists, bar and liquid soaps, detergents/softeners, room sprays, scented candles, and reed diffusers. Particularly useful when a long-lasting “fresh-clean” lift is needed in citrus profiles or when recreating a classic aldehydic style with a modern polish.

Store tightly closed, in a cool place away from light; limit air exposure to preserve freshness. Use gloves and ensure good ventilation during handling. SCENT can provide samples and note-building support to optimize aldehydic performance for each product line.
