Accords inside. This formula contains Petrichor Stone Accord at 280 parts. It is already expanded into the lines above — each material appears once, with the accord's share merged into it — so an accord is never weighed or counted twice.
Composition notes
- Key materials. Grapefruit Oil (Expressed), Vetikol Acetate, Romandolide, Rhubofix, Hexyl Salicylate
- What makes it distinctive. Fruit set against stone — sourness and minerality rather than sweetness and warmth.
- Character. Bracing, original and unisex.
- Concentration. 12–15%
Safety and compliance
- Status. Regulatory assessment pending. No formula-level safety assessment is documented yet, so this page does not say the formula is compliant for any use.
- IFRA Standards. The IFRA Standards Library covers 5 of its materials: Grapefruit Oil (Expressed) (Restriction: Grapefruit oil expressed, Amendment 49); Hexyl Salicylate (Restriction: Hexyl salicylate, Amendment 49); Lemon Oil (Cold-Pressed) (Restriction: Lemon oil cold pressed, Amendment 49); Cashmeran (Restriction: 6,7-Dihydro-1,1,2,3,3-pentamethyl-4(5H)-indanone (DPMI), Amendment 49); Nootkatone (Specification: Nootkatone, Amendment 40).
- Phototoxicity. Grapefruit Oil (Expressed), Lemon Oil (Cold-Pressed) are phototoxic; IFRA limits phototoxic materials in products left on skin exposed to sunlight.
- Skin sensitisation. None of the EU’s long-standing named fragrance allergens is an ingredient in its own right. Natural materials carry further allergens as constituents, declared from the supplier’s data, and Regulation (EU) 2023/1545 extends the list to be labelled on products placed on the EU market from 31 July 2026.
- Product category. Limits depend on the product: fine fragrance, leave-on and rinse-off products have different IFRA categories, and each Standard sets its own figure for each.
