What it is
Helional is a synthetically produced fragrance aldehyde valued for a clean, watery, cyclamen-like floral note often described as marine or oceanic. In sunscreens and other personal care products it contributes to the scent profile rather than to performance or skin benefit. It is used at low levels as one element within a finished fragrance accord.
Safety & warnings
Helional is used as a fragrance material and, like other fragrance aldehydes, can be a potential skin sensitizer in susceptible individuals. Fragrance ingredients are a recognized cause of contact allergy, so those with fragrance sensitivity may wish to avoid products containing it. When listed individually rather than within a generic parfum entry, it is typically present at very low concentrations.
Origin & sourcing
Synthetic. It is manufactured as an aroma chemical for use in fragrance compositions and is not derived from a single natural source.
