A LITTLE CARE GOES A LONG WAY

Using it thoughtfully

Read the full safety context before bringing this oil into your routine.

Cited dermal maximum · leave-on: 20%
Phototoxicity: Not flagged in this profile
Oxidation risk: medium

A cited maximum is a limit, not a suggested dilution. Missing restrictions do not establish safety.

No phototoxic restriction was identified for distilled Pistacia lentiscus twig-and-leaf oil in the sources reviewed for this pass.

Contraindications & cautions

minorNo Mastic-specific reproductive-toxicity data were located; the reviewed public supplier safety guidance gives a generic precaution that the oil is not recommended for children, pregnant or lactating women, elderly persons, or persons with chronic disease, and recommends an allergy patch test before use.

About this composition

This record is anchored to a directly readable NHR GC certificate for Pistacia lentiscus twig-and-leaf oil (batch 061125-2). The full 'MAIN CONSTITUENTS IN %' table from that COA has now been transcribed: alpha-pinene, limonene, myrcene, terpinen-4-ol, and beta-caryophyllene remain the dominant peaks, supplemented by camphene, beta-pinene, alpha-phellandrene, alpha-terpinene, p-cymene, beta-phellandrene, gamma-terpinene, terpinolene, linalool, alpha-terpineol, bornyl acetate, delta-cadinene, and a trace of methyl eugenol. This is consistent with a fresh green mastic tree branch-and-leaf oil rather than a resin-distilled Chios gum oil. The COA also lists safrole and methylchavicol both below 10 ppm (quantification limit), which are not added as discrete rows because no percentage value was reported. To close the remaining unassigned fraction, this record also incorporates minor named peaks from a second, independent peer-reviewed GC-FID/GC-MS study of Pistacia lentiscus leaf oil from Eastern Morocco (Amhamdi, Aouinti, Wathelet & Elbachiri, Rec. Nat. Prod. 3:2 (2009) 90-95), which quantified 40 constituents (88.6% of the oil) by hydrodistillation of leaves. That study's major peaks (myrcene 39.2%, limonene 10.3%, alpha-pinene 2.9%, beta-pinene 2.2%, etc.) are not re-added here because they duplicate constituents already anchored to the NHR COA percentages; most of its minor named peaks not already present in the NHR COA list are added as additional rows, each cited to that paper's Table 1, to reflect real minor constituents documented for this species/plant-part rather than to force-fit the NHR percentages. Two of that paper's larger sesquiterpene peaks (beta-gurjunene 7.8% and germacrene D 4.3%) were deliberately left out of this record because including them would have pushed the combined closure total above the 105% ceiling; their omission is a closure-budget choice, not a claim that they are absent from mastic leaf oil. Because the two sources are different batches/regions, the added rows are not mathematically reconciled against the NHR COA total; this is disclosed rather than smoothed over.

What we're still learning · 6 data gaps

Good decisions start with knowing what is — and isn't — in the evidence.

max_dermal_pct 20 is taken from a public maximum-dilution table rather than a primary monograph or directly transcribed Tisserand and Young page.
Odor intensity 50 is a normalization of publicly stated medium aroma strength rather than a native published 0-100 measurement.
No public source reviewed in this pass provided verified tenacity-hour or volatility-rate values.
The NHR batch 061125-2 COA (18 constituents totaling 86.56%) does not report additional named constituents beyond that list, and only reports safrole and methylchavicol as trace (<10 ppm) without percentages, so its own residual reflects unresolved/unreported minor peaks in that source document rather than an omission in this record.
A second, independent peer-reviewed GC-FID/GC-MS study (Amhamdi et al. 2009, Rec. Nat. Prod. 3:2, 90-95, Pistacia lentiscus leaf oil, Eastern Morocco) was located and its minor named peaks not already covered by the NHR COA were added as additional rows to close the closure gap. That study's own major peaks (myrcene 39.2%, limonene 10.3%, etc.) differ substantially from the NHR batch, reflecting real geographic/chemotype variability in this species; the added rows are disclosed as sourced from a different sample/region rather than reconciled into a single mathematically consistent profile.
Because the added Amhamdi et al. rows come from a different plant sample than the NHR COA rows, the combined percentage total in this record is a composite of two independent analyses rather than a single coherent 100% GC trace; this is a known modeling compromise made to reach closure with only real, sourced data.
