Lily aldehyde CAS Number: 80-54-6
What is it?
Butylphenyl methylpropional (Lilial) is a synthetic chemical in fragrances with a floral aroma.
How do I avoid it?
Skin contact with Lilial is required for it to cause a rash. Discontinuation of exposure to products containing Lilial should result in
improvement and/or resolution of your dermatitis. By law, all products made in the U.S. for topical use have the ingredients listed
either on the product package or the box that contains it, so check the labeling of your skin care products for this ingredient. If there
is not enough information, ask your pharmacist or retailer, or contact the company directly. At work, request a Safety Data Sheet
(SDS) to help identify potential sources of exposure.
The avoidance of fragrances such as Lilial can be difficult, since so many everyday products contain these substances. One should
use only fragrance-free cosmetic and household products. “Unscented” products may contain low levels of a fragrance to cover up
an undesirable odor and also should be avoided. Products labeled as “hypoallergenic” do not assure that the product is truly free
Since fragrances are complex mixtures of many ingredients, an individual may tolerate one fragrance, but not another. A trial-anderror method of avoiding a fragrance allergen in a product can be performed by applying the product to the forearm in the same
small area twice a day for a week. If no dermatitis develops, the product may likely be used safely.
