Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that there is insufficient data to support the safety of Corylus Americana Seed Extract in cosmetic products. Critical information required includes current usage concentrations, extraction methods, quality control measures (chemical analyses), potential contaminants (such as pesticides, heavy metals, and carcinogenic aflatoxins reported in hazelnuts), and comprehensive dermal irritation, sensitization, UV absorption, 28-day dermal toxicity, reproductive/developmental toxicity, and genotoxicity assays. Additionally, cross-sensitivity to proteins found in peanuts and hazelnuts is a reported concern, but the presence or absence of these specific proteins within the extract remains unknown.
