Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

The Cosmetic Ingredient Review (CIR) has not conducted a safety assessment for TETRAHYDRONAPHTHALENOL or its hydroxylated isomers in cosmetic applications. Related compounds such as 1-Hydroxy-1,2,3,4-tetrahydronaphthalene and 2-Hydroxy-1,2,3,4-tetrahydronaphthalene carry GHS hazard statements for skin and serious eye irritation. Exposure to similar compounds, including 6-Hydroxy-1,2,3,4-tetrahydronaphthalene, may cause irritation and potential burns. Skin contact can lead to inflammation and possible systemic effects via absorption. The hydrocarbon 1,2,3,4-Tetrahydronaphthalene (Tetralin) is also noted for irritating skin, eyes, and mucous membranes, and is rapidly absorbed upon ingestion or inhalation.
