3-Methyl-5-(2,2,3-Trimethyl-3-Cyclopentenyl)pent-4-en-2-ol

Sandalore (3-Methyl-5-(2,2,3-Trimethyl-3-Cyclopentenyl)pent-4-en-2-ol) is a synthetic sandalwood odorant developed by Givaudan as a cost-effective and sustainable alternative to natural sandalwood oil, which is derived from the endangered Santalum album tree. It delivers a warm, creamy, woody sandalwood-like scent profile and is notable for its reported skin-conditioning and sensory-enhancing properties, with some studies suggesting it activates the olfactory receptor OR2AT4 in skin, potentially stimulating keratinocyte proliferation and wound healing. Formulators favor Sandalore for its excellent substantivity on skin and hair, its ability to act as a fixative that extends the longevity of fragrance compositions, and its relatively favorable safety and regulatory profile compared to some other synthetic musks and sandalwood substitutes.
