This is a simple solution of 20% pure natural heliotropin crystals in natural triethyl citrate. We dilute it to this level to make it easier for US based customers to purchase legally due to DEA requirements in that place. Heliotropin will contribute a wonderfully sweet and powdery effect to your fragrances and it blends beautifully with other crystallines such as natural Vanillin ex Clove and natural Coumarin ex Cassia. For a full flower option we offer a synthetic Fleur D'Heliotrope base and additionally a rich 100% natural base called Heliotrope Flowers; both are loaded with natural absolutes and oils and exemplify the full beauty of the heliotrope flower in bloom. Note: May require gentle heat as this material may crystallise in cold temperatures. Note: This product contains a diluted form of a regulated chemical and is sold in accordance with NZ regulations. Not for synthesis or diversion. Thai regulations: heliotropin is, according to notification B.E. 2568 (No 3) of the Thai Ministry of Health, officially exempt from restrictions in perfume use to a finished product level of 1%.
