Heart oils are not ordinary essential oils. They are LMR specialities — highly concentrated citrus fractions developed to boost the citrus profile of your formula, enhancing the zesty and fruity notes even at very low dosage. A trace of Lime Heart does what generous amounts of standard lime oil cannot — it persists. LMR describes this as fruity and zesty with clean, fresh, mouthwatering undertones. The fleeting top notes that vanish from conventional lime within minutes are captured here in concentrated form. What remains is the most intensely lime impression you can put in a bottle — bright, sharp, unmistakable. Use just a hint to extend lime presence from top note well into the heart. Layer it over our Persian Lime Oil FCF for a citrus accord that opens with natural breadth and refuses to fade. Essential in gin-and-tonic accords, mojito constructions, and any bright aquatic or citrus cologne that needs staying power.
