Lemongrass Essential Oil (Aromatic and Allied Chemicals®)

A forceful lemon impression leads the opening, accompanied by grass-like greenness and aromatic herbal notes. Its edge is incisive and faintly metallic, with a subtle soap-like freshness rather than the sweeter character of expressed citrus peel. Earth and hay nuances give the underlying profile more depth than a straightforward lemon note. The initial impact declines rapidly; the supplier does not describe a distinct heart-stage development or a timed blotter evolution.

Provides an assertive citrus-green opening with a keen grassy freshness, giving a less sweet, more natural impression than expressed peel oils. It is suited to cologne structures and fresh masculine fragrances, and lends a clean character to functional compositions. In aromatic blends it supports herbal themes with basil and mint; citrus and tea accords are also identified as applications.

The supplier gives 0.2–2% of the fragrance concentrate as its usual formulation range, reflecting the oil's strong character. A separate recommendation of 0.1–3% refers to finished fragrance, not concentrate. These are application guidelines, not IFRA limits.

No confirmed manufacturer use level for this exact product.

Tenacity

The page reports 92 hours of blotter substantivity, attributing the figure to TGSC; evaluation dilution and other test conditions are unspecified. This should be distinguished from the rapidly fading opening impact described elsewhere on the page.

Diffusion, tenacity and note impact are not combined into a single performance score.

Solvents

Clear solutions are reported with ethanol, DPG or IPM. Water-containing alcohol mixtures produce cloudiness.

Working dilution

Prepare a 10% working solution in ethanol for compounding and a 1% solution for olfactory assessment. The supplier also lists DPG and IPM as suitable dilution vehicles.

Appearance

Liquid, ranging in colour from yellow through brownish tones.
