Description

Hydroxyisolongifolaldehyde is a high-value sesquiterpene aldehyde derivative prized for its unique woody, ambery, and slightly animalic olfactory profile. Its significance lies in its ability to impart complex, long-lasting base notes and enhance the natural character of fragrance compositions. This compound is essential for perfumers and flavorists seeking to create sophisticated, high-end consumer products in the fragrance, personal care, and fine flavoring industries.

Application

• Fragrance Industry: A key building block in premium perfumery for creating woody, ambery, and musk accords in fine fragrances, colognes, and body care products.
• Personal Care Products: Used as a fragrance ingredient in soaps, lotions, shampoos, and deodorants to provide depth and persistence.
• Flavor Enhancers: Employed in trace amounts to add subtle woody and balsamic nuances to specialty food and beverage flavorings.
• Aroma Chemical Synthesis: Serves as a valuable intermediate for the synthesis of more complex fragrance molecules and derivatives.
• Household & Industrial Fragrances: Incorporated into air fresheners, detergents, and fabric softeners for a premium scent profile.
• Cosmetic Ingredients: Used in cosmetic formulations where its specific scent profile contributes to the product's sensory appeal.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve stability and prevent degradation. Keep away from strong oxidizing agents.
