About this composition

This profile uses Aromatics International's public Italian grapefruit batch-history endpoints. The directly readable batch series shows an Italy-origin cold-pressed grapefruit oil consistently dominated by d-limonene with beta-myrcene as the secondary constituent and small sabinene, alpha-pinene, aldehyde, and sesquiterpene fractions.

What we're still learning · 3 data gaps

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

The numeric odor intensity is an archive normalization from supplier language describing the oil as sparkly and refreshing rather than a native published 0-100 metric.
Missing public source type: a directly viewable primary phototoxic monograph or IFRA/Tisserand page for Italian grapefruit specifically; the public 4% limit located this pass is a secondary safety transcription.
No public source located in this pass gave directly measured volatility-rate or tenacity-hour values for Italian grapefruit essential oil.
