Flavor use consideration: Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org). For more details see chapter 1 of the Guidance for the use of IFRA Standards.

Creative ideas to explore
Creative directions, not tested formulas.Petals and peel
With bergamot and a light citrus ideaExplore a brighter version of the floral character using a simple citrus counterpoint. Compare it with the unchanged flower accord and note whether the citrus frames the bloom or becomes the main subject of the sketch.
Stem and blossom
With geranium and leafy notesSketch the flower with a greener setting, keeping leaf and blossom as distinct ideas. Compare a clean floral reference with the greener version to decide how much of the imagined stem and garden belongs in the composition.
Petals over wood
With a transparent wood directionPlace the floral material against a spare wood backdrop and follow the balance through the evaluation. Try a softer wood variation separately, then choose whether your flower needs an open, airy setting or a smoother, more enveloping frame.
