About

A fragrance aldehyde with skin irritation potential (H315) used as a scent component in perfumes and cosmetics.

AR-Isopropylphenylacetaldehyde is a synthetic fragrance ingredient with a green, floral odor profile. The GHS hazard statement H315 indicates it can cause skin irritation, which is a concern for leave-on cosmetic applications. It is not specifically restricted under EU Regulation 1223/2009, though IFRA standards may impose concentration limits based on the skin irritation potential. The fragrance industry uses this ingredient at low concentrations in fine fragrances and cosmetic products to achieve specific scent profiles, with typical use levels well below those that would cause sensory irritation in most consumers.
