Orange Oil, Sweet in car care products

Orange Oil, Sweet (CAS 8008-57-9) appears in 6 of the 2,122 car-care products CarCareTruth tracks (as of August 2026), 1 of which carry a DANGER signal word on their published Safety Data Sheet. It is classified as a respiratory sensitizer (asthmagen) and classified as a VOC.

H315 (Skin Irritation Cat 2), H317 (Skin Sensitizer Cat 1 — d-limonene component), H226 (Flammable Liquid Cat 3), H304 (Aspiration Hazard Cat 1). D-limonene is the primary sensitizing component and is on AOEC asthmagen list. At detailing-product concentrations (0.1–1% of concentrate), skin sensitization is the primary real-world concern for repeat users. Not Prop 65 listed.

Orange oil, sweet (CAS 8008-57-9) is a cold-pressed citrus peel essential oil used in cleaning products as both a fragrance ingredient and a mild solvent. Its primary active constituent is d-limonene (typically 90–95% of the oil by weight).

Asthmagen status: d-Limonene, the dominant component, is on the AOEC (Association of Occupational and Environmental Clinics) asthmagen list as a workplace sensitizer. Orange oil sweet inherits this designation. However, at product-level fragrance concentrations (0.1–1% of concentrate), the asthmagen risk is primarily relevant for occupationally exposed workers with repeated daily exposure — not for home detailers using the product occasionally. The asthmagen flag is set here for accurate ingredient-level disclosure; product-level scoring applies the category rubric rules for asthmagen triggers.

Skin sensitization: d-Limonene (H317 Skin Sens. Cat 1) is among the most common causes of occupational contact allergy in European patch-test studies. At fragrance concentrations in APCs, cumulative sensitization over repeated use is the primary mechanism. Users who develop a limonene allergy may react to products at concentrations well below the GHS classification threshold.

Aspiration hazard: H304 (Asp. Tox. 1) at ingredient level reflects orange oil's viscosity and lipophilicity — relevant only for accidental ingestion scenarios, not for skin contact or inhalation during normal use.
