About
Rhodinyl Isovalerate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Rhodinyl Isovalerate (rhodinyl isovalerate, also called rhodinyl 3-methylbutanoate) is an aromatic ester providing sweet rose-floral notes reminiscent of rhodinol derived from geranium and palmarosa. It appears in the EU CosIng database without specific restrictions beyond standard fragrance allergen obligations. Under EU Regulation 1223/2009 Annex III, fragrance allergens must be declared on ingredient labels when present above threshold concentrations (0.001% in leave-on, 0.01% in rinse-off). The compound has low acute toxicity but like most fragrance esters may cause contact sensitisation in predisposed individuals.
Known concerns
- Fragrance allergen — requires mandatory labelling under EU Annex III
- Potential skin sensitisation in susceptible individuals
- Limited comprehensive repeat-dose toxicity data
