2-ethylhexyl 4-aminobenzoate

2-ethylhexyl 4-aminobenzoate is an organic chemical compound with the molecular formula C15H23NO2 and CAS number 26218-04-2. This aminobenzoate ester has a molecular weight of 249.35 g/mol and belongs to the para-aminobenzoic acid (PABA) derivative family. It is classified as hazardous to aquatic environments and requires careful handling according to GHS regulations with warning pictogram GHS09.

2-ethylhexyl 4-aminobenzoate is typically a liquid or low-melting solid at room temperature due to its branched alkyl chain structure. The compound exhibits limited water solubility but shows good solubility in organic solvents and oils. Its molecular structure combines an aromatic aminobenzoate core with a branched 2-ethylhexyl chain, providing both polar and nonpolar characteristics that influence its handling and application properties.

2-ethylhexyl 4-aminobenzoate is primarily used as a UV filter and sunscreen agent in cosmetic and personal care formulations. It provides protection against UVB radiation and is commonly incorporated into sunscreen products, moisturizers, and other topical applications. The compound may also find applications in industrial UV-absorbing formulations and as an intermediate in pharmaceutical or chemical synthesis processes requiring UV protection properties.

Safe handling of 2-ethylhexyl 4-aminobenzoate requires standard chemical safety precautions including wearing appropriate personal protective equipment such as gloves, safety glasses, and protective clothing. Work in well-ventilated areas to minimize exposure. Given its aquatic toxicity classification (Aquatic Acute 1, Aquatic Chronic 1), prevent environmental release and ensure proper containment. Follow GHS warning label instructions and maintain good industrial hygiene practices during use.

2-ethylhexyl 4-aminobenzoate should be stored in tightly closed containers in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep away from incompatible materials such as strong oxidizing agents. Ensure storage areas have appropriate containment measures to prevent environmental contamination due to its aquatic toxicity. Store according to local regulations and maintain proper labeling with GHS pictogram GHS09 and warning signals.

In case of skin contact with 2-ethylhexyl 4-aminobenzoate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water. For eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention if irritation persists. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention while providing the safety data sheet to medical personnel.

Disposal of 2-ethylhexyl 4-aminobenzoate must comply with local, national, and EU waste regulations due to its aquatic toxicity classification. The substance should be treated as hazardous waste and disposed of through licensed waste management facilities capable of handling environmentally hazardous materials. Never discharge to sewers, waterways, or soil. Container disposal should follow local regulations, and empty containers may retain hazardous residues requiring appropriate treatment.

2-ethylhexyl 4-aminobenzoate is classified under ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. This classification requires appropriate packaging, labeling, and documentation according to dangerous goods transport regulations. Shipments must include proper shipping names, UN numbers, and hazard labels. Transport vehicles should carry appropriate emergency response information, and drivers must be trained in dangerous goods handling procedures according to ADR requirements.

2-ethylhexyl 4-aminobenzoate is subject to EU REACH regulation for chemical registration and evaluation, though it is not currently listed as a Substance of Very High Concern (SVHC). The compound must comply with CLP regulation for classification and labeling, requiring GHS09 pictogram and warning signal due to its aquatic toxicity. Additional cosmetic regulations may apply when used in personal care products, and transport is governed by ADR dangerous goods regulations.
