What is Lavandin Grosso Oil?

Lavandin Grosso (Lavandula × intermedia ‘Grosso’) is a sterile hybrid of true lavender (Lavandula angustifolia) and spike lavender (Lavandula latifolia), selected for its high oil yield and robustness. The essential oil is obtained via steam distillation of flowering tops, yielding an intense, volatile-rich aromatic material.

Its chemical composition typically includes:

• Linalool (35–45%)

• Linalyl acetate (25–35%)

• 1,8-Cineole (~6–10%)

• Camphor (~5–7%)

• Terpinen-4-ol, borneol, lavandulol (minor fractions)

The oil is more volatile and less sweet than L. angustifolia essential oil, making it suitable for applications where sharp freshness and economical dosage are needed.

Olfactory Profile & Perfumery Applications

Lavandin Grosso oil offers a bright, cineole-rich opening that is distinctly herbal without excessive camphor. It rapidly transitions into woody-aromatic tones that complement modern fougère structures.

Typical use cases include:

• Fougère Accords: Core material for barbershop, masculine, and lavender-forward structures

• Aromatic Blends: Synergizes with clary sage, rosemary, pine, and thyme

• Functional Fragrances: Effective in soaps, shampoos, and deodorants due to its volatility and freshness

• Citrus & Cologne Bases: Adds lift and diffusion in citrus-herbal structures

Industrial & Technical Uses

• Fine Fragrance: Foundational material in cost-effective fougère and aromatic blends

• Personal Care: Frequently used in soaps, bath gels, deodorants, and lotions for lasting freshness

• Household Products: Effective in laundry care, air fresheners, and disinfectant blends

• Aromatherapy: Sometimes used as a stimulant or for respiratory support due to 1,8-cineole content

Due to its higher camphor and cineole content, it should be differentiated from true lavender oil in applications requiring delicacy.

Regulatory & Safety Overview

• IFRA Guidelines: No usage bans; follow QRA standards for essential oils in Category 4–10 products
