Fragrancing SPF Product
I’ve been developing an SPF product, and need to find something to give it a pleasant fragrance - client has requested that there not be “Parfum” on the INCI, so I’m realistically looking at an essential oil or floral waters. Having tested a number of floral waters, they’ve proven lacking, so I’m down to essential oils.
I’m aware from previous experience that some essential oils can massively reduce the SPF value when tested in-vivo, due presumably to their sensitising properties. My question is: does anyone have experience of successfully using essential oils to fragrance SPF products, or failing that is anyone aware of any data available for the influence of various essential oils on the in-vivo SPF?
