What is Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde (HICC / Lyral)?
Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde, commonly known as HICC or Lyral, is a synthetic fragrance compound. It is typically manufactured through a chemical process that involves the cyclohexene structure.
HICC is widely used in fragrances and personal care products for its floral, delicate scent. There is significant evidence linking HICC to allergic reactions, particularly contact dermatitis, leading to its regulation in various markets.
Due to its allergenic potential, consumers may want to be cautious when they encounter it on a product label, especially if they have a history of skin sensitivities.
Commonly found in: Perfumes, Body lotions, Soaps, Shampoos
What to watch
- May cause allergic skin reactions such as contact dermatitis.
- Identified as a common allergen by dermatologists.

Several studies indicate allergenic potential, leading to differing regulations in cosmetic usage.
HICC is synthetically derived and not animal-based, making it vegan-friendly.

Scout's take
BANNED in EU cosmetics since August 2021 as an extreme dermal sensitizer (EU Reg. 2017/1410). Tested at ~2% positive rate in fragrance-allergy patch panels. Still appears in US-market reformulations of legacy designer fragrances because the US has no equivalent ban. Worst-class contact allergen.
