Lyral

 Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde, also called HMPCC, is a clear, colorless liquid with a delicately sweet, light, floral odor. In cosmetics and personal care products, Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde is used in the formulation of aftershave lotions, bath products, bubble baths, hair conditioners, moisturizers, perfumes and colognes, skin care products and suntan products. Hydroxyisohexyl 3-cyclohexene carboxaldehyde, also known as Lyral, is a fragrance ingredient identified as the cause of contact allergic reactions in 2-3% of eczema patients undergoing patch testing. Lyral has been included in the standard patch test series in many clinics due to its importance as an allergen.
