Rose geranium shifts the aromatic balance of standard geranium towards a fuller, more convincing rose character, owing to a higher proportion of geraniol and esters including geranyl formate and citronellyl formate that soften and sweeten the profile. Citronellol remains the dominant constituent (typically 40-44%), but the elevated geraniol fraction makes it the preferred variety for perfumers seeking an affordable rose substitute. A GC-MS characterisation of P. roseum oil demonstrated antimicrobial activity against Gram-negative and Gram-positive bacteria as well as complete inhibition of Candida albicans growth in disc-diffusion assays.^[1] The rose-scented P. graveolens composition study further confirmed superior antioxidant capacity and broad-spectrum antibacterial reach across multiple assay systems.^[2]
