"I stopped rebuying little bottles. One 500ml Garden Bloom refill has kept my living room diffuser going for over a year. Same rose-and-jasmine scent, a fraction of the cost."

Is one more natural? An essential oil is a single natural extract; a good fragrance oil is built on real and naturally-derived materials but composed for balance and performance. SOSA refills are naturally-derived, phthalate-free, paraben-free, IFRA-compliant and low-VOC, on a coconut-derived (CCT) base.
Which is better for a reed diffuser? A composed fragrance oil - it wicks evenly and holds its scent for months, where a neat essential oil fades fast and wicks unevenly.

Fragrance oil and essential oil are often confused. Here is the real difference, and which suits a reed diffuser.
Quick answers — read this first
What's the difference between fragrance oil and essential oil? An essential oil is a single raw plant extract (e.g. neat lavender). A fragrance oil is a composed blend of aromatic materials - which can include naturally-derived ones - built to perform (balanced, stable, long-lasting). For a reed diffuser, the composed oil wicks better and lasts longer. SOSA reed refills from ₹2,399.Is one more natural?

The short answer
Short answer: essential oil = a single raw extract; fragrance oil = a composed, made-to-perform blend.
For reeds: a composed reed fragrance oil wins, from ₹2,399.
SOSA: naturally-derived, composed to last.
Straight answer
Single raw extract vs composed-to-perform blend
The difference is simplicity versus composition. An essential oil is a single raw plant extract - pure lavender, pure lemon - valued in aromatherapy but variable and fast-fading. A fragrance oil is a composed blend of aromatic materials (which can include naturally-derived ones), built for balance, stability and performance - for example, to wick steadily through reeds and hold a scent for months. Neither is automatically "better"; they are for different jobs. For a reed diffuser, a composed fragrance oil is the right tool, and SOSA reed refills are built on real, naturally-derived materials, phthalate-free, paraben-free, IFRA-compliant and low-VOC, on a coconut-derived (CCT) base. From ₹2,399.
