Geranyl Linalool, a colorless to light yellow transparent liquid, is a monoterpene alcohol derivative that exists naturally in jasmine absolute and narcissus absolute. It has both the fresh floral fragrance of linalool and the sweet fruity fragrance of geraniol. Its aroma is complex and rich in layers, and is widely used in perfumes, daily chemicals and food flavors.
I. Basic properties and aroma characteristics
Chemical structure: molecular formula C₁₅H₂₆O, containing terpene skeleton and multiple unsaturated double bonds, the structure has the characteristics of linalool and geraniol.
Physical properties: colorless to light yellow liquid, boiling point about 260-265℃, insoluble in water, soluble in ethanol, oil and organic solvents.
Aroma characteristics:
Floral fragrance: fresh and sweet similar to lily of the valley and orange blossom.
Fruity fragrance: soft fruity aftertaste with peach and lychee.
Green notes: a faint herbal or citrus leaf scent, enhancing the naturalness of the fragrance.
Persistence: moderate volatility, lasting for about 4-6 hours, suitable for the transition from middle notes to base notes.
II. Perfumes and high-end fragrances
(1) Construction of core notes
Floral notes:
As the skeleton component of white flower perfumes (such as jasmine and gardenia), it is compounded with phenylethyl alcohol and benzyl acetate to enhance the fullness of the floral fragrance. Application example: geranyl linalool (2%) + damascena ketone (0.5%) + ylang ylang oil (1%) → tropical white flower fragrance base.
Fruity notes:
In peach and apricot fragrances, it simulates the juiciness of the pulp and synergizes with γ-decanoic acid (coconut lactone) to enhance the milky layer.
Citrus notes:
Combined with limonene and nerolidol, it balances the sharpness of citrus and gives a soft aftertaste (such as summer cologne).
(2) Fixing and coordinating functions
Delaying the volatilization of aldehydes (such as decanal) and esters through intermolecular interactions, stabilizing the transition stage of the fragrance. Neutralizing the powdery texture of synthetic musk and enhancing the natural affinity of the formula.
III. Daily chemical product fragrances
(1) Personal care products
Skin care products (lotions, essences):
Provide a light floral scent and act as a softener to enhance the skin feel (dosage 0.1%-0.5%).
Combined with bisabolol, it has both soothing and fragrance-adjusting functions (suitable for sensitive skin products).
Shampoo and conditioner:
Mask the chemical smell of surfactants and give a "garden after shampooing" scent (dosage 0.05%-0.2%).
(2) Household cleaning and detergents
Softener and laundry detergent:
Mixed with styrax acetate (1:1), it simulates the clean feeling of clothes dried in the sun.
Aromatherapy candles:
Good high temperature resistance, as a middle note component to prolong the release of floral fragrance (dosage 1%-3%).
IV. Food and oral care flavors
(1) Food flavor enhancement
Fruit flavors:
Used in peach, lychee, and mango flavors to enhance the sweetness and juiciness of the fruit pulp (dosage 5-20 ppm).
Combined with maltol, it enhances the caramelization level of tropical fruit flavors.
Dairy products and beverages:
Balance acidity in yogurt and ice cream to give a creamy aftertaste (dosage <10 ppm).
(2) Oral care products
Toothpaste and mouthwash:
Synergize with menthol and methyl salicylate to reduce cooling stimulation and provide a mild fruity aftertaste (dosage 0.01%-0.1%).
