Butylphenyl Methylpropional — answers to Lyral (a synthetic fragrance ingredient)
Appears in 1 scanned product.
A synthetic fragrance compound with a floral, lily-of-the-valley type scent, once common in perfumes, shampoos, and lotions.
Why it’s used
Added purely for scent, contributing a soft floral note to fragrance blends.
What the evidence says
The SCCS found evidence of skin sensitization in a meaningful number of users, meaning it can trigger allergic contact dermatitis in some people with repeated exposure, and it is one of the fragrance substances the EU requires to be named on the label. The EU ban rests on different grounds: it has been prohibited in cosmetics since 1 March 2022 as a substance classified as toxic for reproduction, not because of sensitization.
Context
Sensitization risk is concentration-dependent and rises with leave-on, repeated-use products like lotions and perfumes more than with rinse-off products. Because of the EU ban, it should no longer appear in cosmetics sold there; formulations elsewhere may still contain it.
