ETHYLHEXANAL.

Avoid CAS 123-05-7 / PERFUMING

Ethylhexanal, also known as 2-Ethylhexanal, is an aldehyde primarily employed in cosmetic formulations as a perfuming agent and solvent. It serves as a chemical intermediate in various industries, contributing to the scent profile of products.

perfuming solvent

Science

This compound primarily functions by imparting a fragrance to cosmetic products and acting as a solvent to dissolve other ingredients. As an aldehyde, it can participate in chemical reactions, notably as an intermediate, and has been identified as a metabolite in fungal and bacterial processes.

Stability

Ethylhexanal is air-sensitive and prone to oxidation, readily forming carboxylic acids, a process accelerated by light and transition metal catalysts. It also undergoes exothermic self-condensation and polymerization, typically catalyzed by acids. It exhibits slight solubility in water (approximately 0.01 g/L or 400 ppm at 25 °C) and is miscible with most organic solvents, including alcohols.

Safety

CIR Status
Not reviewed
Pregnancy
Caution
Sensitization risk High

Ethylhexanal lacks a specific safety assessment from the CIR or SCCS. It is classified with GHS pictograms indicating flammability, irritancy, and health hazards. Hazard statements include H226 (flammable liquid and vapor), H317 (may cause an allergic skin reaction), and H361 (suspected of damaging fertility or the unborn child). Risk statements denote flammability (R10), irritation to eyes, respiratory system, and skin (R36/37/38), and potential for sensitization via skin contact (R43). It demonstrates moderate toxicity via ingestion and intraperitoneal routes, and mild toxicity upon inhalation and skin contact. Direct liquid contact can cause first-degree burns from short exposure and second-degree burns from prolonged contact.

Our Assessment

Avoid

Due to its high irritancy, significant sensitization risk, suspected reproductive toxicity, and lack of comprehensive cosmetic safety review, Ethylhexanal is strongly advised against for use in precision skincare formulations.
