What is Nectarate?

Nectarate is a synthetic ester classified under saturated polycyclic carboxylic acid esters. It features a tricyclic backbone esterified with butanoic acid, engineered for olfactory clarity, chemical stability, and controlled volatility. Developed by IFF as part of their internal fruity materials portfolio, Nectarate is designed for use in formulations requiring realistic stone fruit character without aldehydic sharpness or instability.

Its low reactivity and resistance to hydrolysis make it compatible with various product matrices including aqueous, surfactant-rich, and emulsion systems.

Olfactory Profile & Perfumery Applications

👃🏼 Scent Description: Nectarate opens with an immediately juicy, uplifting peach-nectarine tone. The fruity note is rounded by a soft, woody undertone, making it useful in both naturalistic and abstract accords.

⚗️ Functional Role:

• Operates as a top-to-heart note modifier

• Enhances the realism of fruity accords (especially peach, mango, apricot)

• Adds softness to floral-lactonic blends (e.g., jasmine, tuberose)

• Improves substantivity through rinse cycles (textiles, hair care)

🧴 Blends well with:

• Lactones (gamma-undecalactone)

• Hedione-type musks

• Light woody materials (ambrox, iso E derivatives)

It is particularly effective in summer, tropical, or gourmand profiles, and can be used to mask synthetic harshnessin cost-sensitive functional fragrance bases.

Industrial & Technical Uses

While primarily used in perfumery, Nectarate is also FEMA-listed (No. 2735) for flavor applications under restricted concentrations. It has been used in:

• Beverage flavorings

• Chewing gum and candy

• Ambient air fresheners and aromatherapeutic diffusers

Due to its favorable organoleptic profile, it contributes a mood-lifting, appetizing character to ambient and consumer product formulations. It is not reactive and is not used in chemical synthesis beyond perfumery and flavor contexts.

Regulatory & Safety Overview

• IFRA: Not restricted under current 51st Amendment

• EU Allergens: Not among the 26 declarable fragrance allergens
