3,7-Dimethyl-7-hydroxyoctanal, more commonly known as Hydroxycitronellal (CAS: 107-75-5), stands as a cornerstone in the world of aroma chemicals. This colorless, viscous liquid, with its precise molecular formula C10H20O2 and a molecular weight of 172.26, is highly prized for its exceptional sensory profile and remarkable versatility across numerous industries. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer this high-purity compound, typically achieving an assay of 98% or higher, ensuring premium quality for diverse applications.

The allure of Hydroxycitronellal lies in its captivating scent. It is renowned for its sweet, delicate floral aroma, beautifully reminiscent of the lily of the valley (muguet), lilac, and linden blossom. Beyond these classic floral notes, it often presents subtle fresh, aldehydic, citrus, and melon undertones, making it an incredibly multifaceted ingredient. Its ability to impart such a rich and nuanced fragrance has cemented its status as one of the most valuable spices and a preferred floralizing perfume material for perfumers globally. This elegance and radiance allow it to add significant lift and character to complex fragrance blends, serving as an indispensable enhancer.

The applications of Hydroxycitronellal are extensive, spanning from luxury goods to everyday essentials. In the perfumery sector, it is a crucial component in creating authentic floral accords, particularly for "mute flower" scents like lily of the valley, peony, and narcissus. Its excellent fixing properties ensure longevity and diffusion of the fragrance, allowing the odor profile to remain consistent for extended periods. Historically, Hydroxycitronellal has been a key ingredient in many mid-century fragrance masterpieces, and its demand continues to be strong, underscoring its timeless appeal. Perfumers often incorporate it into various types of floral and even non-floral fragrances, with concentrations varying to achieve desired effects, from subtle enhancements to dominant floral notes.

Beyond fine fragrances, Hydroxycitronellal finds widespread use in the cosmetics and personal care industry. It is a common ingredient in formulations for deodorants, soaps, antiseptics, hair sprays, skin care products, lotions, creams, shampoos, and conditioners. Its pleasant aroma enhances the consumer experience, contributing to the luxurious feel of these products. Furthermore, it is incorporated into various household items, including air fresheners, cleaning products, laundry care, and dishwashing products, ensuring a delightful scent throughout the home environment.

Notably, Hydroxycitronellal is also approved as a flavoring agent for direct addition to food, used to prepare citrus fruit flavors such as citrus, watermelon, and cherry. Its ability to impart a floral fragrance while thickening and rounding out flavors makes it a valuable additive in the food industry, adhering to stringent regulations for edible flavors.

While naturally occurring in certain essential oils like lavender and citronella, Hydroxycitronellal is predominantly produced synthetically through the hydration of citronellal, ensuring consistent purity and supply. Proper packaging in blue steel drums (typically 180kg per drum) and storage in a cool, dry place, away from open flames, high temperatures, and oxidants, are crucial for maintaining its quality and stability. Due to its potential for oxidation, antioxidants are sometimes added for stabilization, and its acetal forms are preferred in alkaline environments like soaps.

In terms of safety and regulatory compliance, NINGBO INNO PHARMCHEM CO.,LTD. adheres to global standards. While Hydroxycitronellal is widely used, it is recognized as a potential sensitizer for some individuals, leading to regulations by bodies such as the International Fragrance Association (IFRA) and the European Union. These regulations specify maximum concentration levels in various product categories and require clear labeling when present above certain thresholds, ensuring consumer safety without compromising its beneficial aromatic qualities.
