## Composition (GC-MS research aggregate)

Based on 15 GC-MS samples from 9 peer-reviewed papers (2016–2026); Moderate evidence base. 64 compounds reported in total. Typical share of the oil (median, with interquartile range):

| Compound | Class | Median % | IQR % | Max % | Papers |
|---|---|---|---|---|---|
| limonene | Monoterpene hydrocarbon | 33.35 | 3.86–85.33 | 95.3 | 7 |
| linalyl acetate | Oxygenated monoterpene | 22.23 | 6.84–40.87 | 57.13 | 4 |
| linalool | Oxygenated monoterpene | 7.69 | 1.5–26.35 | 30.2 | 7 |
| geranyl acetate | Oxygenated monoterpene | 4.83 | 2.7–5.95 | 10.12 | 5 |
| α-terpineol | Oxygenated monoterpene | 3.75 | 2.1–5.39 | 7.06 | 6 |
| nerolidol | Oxygenated sesquiterpene | 4.61 | 3.44–5.21 | 6.91 | 4 |
| myrcene | Monoterpene hydrocarbon | 1.33 | 1.05–1.69 | 3.5 | 8 |
| β-pinene | Monoterpene hydrocarbon | 0.99 | 0.78–1.61 | 3.98 | 7 |
| β-caryophyllene | Sesquiterpene hydrocarbon | 0.36 | 0.21–0.95 | 1 | 5 |
| terpinolene | Monoterpene hydrocarbon | 0.43 | 0.33–0.44 | 0.44 | 4 |
| α-pinene | Monoterpene hydrocarbon | 0.24 | 0.16–0.33 | 0.4 | 4 |

Chemotypes seen in the samples: limonene (33% of samples), linalyl acetate (27% of samples), linalool (13% of samples), caryophyllene oxide (13% of samples), d-limonene (9) (7% of samples), 1,8-cineole (7% of samples).

## Key constituents

- **Linalyl acetate** (40-55%) — The dominant ester, giving petitgrain a soft, sweet-green character
- **Linalool** (20-30%) — Adds a floral-woody softness beneath the ester note

## How to use it

- **In the diffuser:** 3–5 drops is a refreshing, daytime-friendly scent that layers with florals and woodsy notes.
- **On skin:** Dilute to 2–4% in a carrier oil; also popular in scalp and hair-care blends.

## Safety

- As a leaf oil rather than an expressed peel oil, petitgrain doesn't carry citrus phototoxicity concerns — still, dilute and patch-test before use.
- Maximum dermal use: Dilute in a carrier oil for skin.
- A gentle, well-tolerated oil; it contains linalool and linalyl acetate, so patch-test if you have sensitive skin.
- Not phototoxic — distilled from leaves, it carries none of the phototoxic coumarins of citrus peel oils.
- Keep out of reach of children.

## What the research says

- Petitgrain shares its calming, linalool-and-linalyl-acetate chemistry with lavender and neroli. Its relaxing reputation is traditional and preliminary rather than clinically established. — Italian Citrus Petitgrain Oils study (1997) (https://doi.org/10.1080/10412905.1997.10554241)

## Evidence

- Petitgrain is an ester-rich oil dominated by linalyl acetate and linalool — a soft, green-floral profile close to neroli's, from the same tree. — Italian Citrus Petitgrain Oils study (1997) (https://doi.org/10.1080/10412905.1997.10554241)

## Frequently asked questions

### What is petitgrain made from?

Petitgrain is distilled from the leaves and twigs of the bitter orange tree (Citrus aurantium) — the same tree that gives neroli (from the blossoms) and bitter orange (from the peel). Three oils, three plant parts.

### Is petitgrain phototoxic?

No — because it's distilled from leaves rather than pressed from peel, it carries no phototoxic coumarins. There's no sun-exposure restriction.

### How is petitgrain different from neroli?

Both are ester-rich and calming, but petitgrain (leaves/twigs) is greener, fresher, and far more affordable, while neroli (blossoms) is softer, sweeter, and much pricier.
