Shower melts and steamers release scent into hot, humid air, a harder test than a room-temperature product, and myrtle's clear top note is built to survive it. This page is part of our Guide to Buying Myrtle Essential Oil in Bulk.
Test scent throw at real shower temperature before you scale the batch.
Heat and steam intensify a fragrance, so an oil that is already sharp at room temperature can turn overpowering in a shower stall. Myrtle's balance of a cool, fresh opening against a soft floral undertone keeps it readable rather than harsh once steam carries it through the air, a pairing our shower melt recipe builds around alongside eucalyptus.
Because the floral facets sit underneath the initial coolness rather than competing with it, a shower melt built on myrtle reads as a clean wake-up scent through the whole steam cycle rather than fading to nothing after the first few minutes.
Bath and shower makers typically suspend the essential oil blend in a citric acid and baking soda base for melts and steamers, adding the oil late in the mixing process to limit the fizzing reaction from stripping scent before the product sets.
Because heat pulls scent out faster than a room-temperature product, brands should test a shower melt's scent throw at the actual water temperature customers will use, not at the mixing bowl, before finalizing a usage rate.
A brand testing a new melt or steamer recipe can start with a 2 oz or 4 oz bottle, moving to 5 lbs once the scent throw and usage rate are confirmed at production scale.
Order 5 lbs or 25 lbs once your usage rate is locked in.
