2-ethylhexyl 4-aminobenzoate

2-ethylhexyl 4-aminobenzoate is an organic compound with the molecular formula C15H23NO2 and CAS number 26218-04-2. This chemical belongs to the aminobenzoate family and has a molecular weight of 249.35 g/mol. It is classified as hazardous to the aquatic environment with both acute and chronic toxicity (Aquatic Acute 1, Aquatic Chronic 1). The substance carries a Warning signal word and requires the GHS09 environmental hazard pictogram for proper labeling.

2-ethylhexyl 4-aminobenzoate is an organic ester compound that typically appears as a liquid or solid depending on temperature conditions. The molecule contains both an amino group and an ester functional group, which influences its solubility characteristics. Given its molecular structure with a long alkyl chain (2-ethylhexyl group), it likely exhibits limited water solubility but good solubility in organic solvents. Its molecular weight of 249.35 g/mol indicates moderate volatility under standard conditions.

2-ethylhexyl 4-aminobenzoate is primarily used as a UV filter and sunscreen agent in cosmetic and personal care formulations. Its aminobenzoate structure provides effective UV-B radiation absorption, making it valuable for sun protection products. The compound may also find applications in industrial formulations where UV protection of materials is required. Additionally, it can serve as an intermediate in the synthesis of other chemical compounds or as a component in specialized coatings and plastics requiring UV stability.

2-ethylhexyl 4-aminobenzoate requires careful handling due to its environmental hazard classification. Workers should wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Ensure adequate ventilation in work areas and avoid release to the environment. Handle in well-ventilated areas or under local exhaust ventilation. Wash hands thoroughly after handling and avoid eating, drinking, or smoking during use. Emergency eyewash and safety shower facilities should be readily accessible.

2-ethylhexyl 4-aminobenzoate should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly closed when not in use to prevent contamination and minimize environmental release. Store away from incompatible materials such as strong oxidizing agents. Ensure storage areas have appropriate containment measures to prevent environmental contamination in case of spills. Maintain storage temperature according to supplier specifications and regularly inspect containers for signs of damage or deterioration.

In case of skin contact with 2-ethylhexyl 4-aminobenzoate, immediately wash the affected area with plenty of soap and water for at least 15 minutes and remove contaminated clothing. For eye contact, flush immediately with clean water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air and keep them in a comfortable position for breathing. If ingested, do not induce vomiting and rinse mouth with water. Seek medical attention if irritation persists or if large amounts were involved.

2-ethylhexyl 4-aminobenzoate must be disposed of as hazardous waste due to its environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1). Contact licensed waste disposal companies specialized in chemical waste management for proper disposal. Never discharge to sewers, waterways, or soil as this can cause significant environmental damage. Small quantities should be collected in appropriate containers and labeled clearly. Follow local and national regulations for hazardous waste disposal, including proper documentation and waste tracking requirements.

2-ethylhexyl 4-aminobenzoate is classified as ADR Class 9 (Miscellaneous Dangerous Goods), Packing Group III for transportation purposes. This classification requires specific packaging, labeling, and documentation according to international dangerous goods regulations. Packages must display appropriate hazard labels and proper shipping names. Transport vehicles require appropriate placarding and drivers need hazardous materials training certification. Ensure proper segregation from incompatible materials during transport and have emergency response information readily available throughout the shipping process.

2-ethylhexyl 4-aminobenzoate is subject to REACH regulation in Europe, requiring registration for import or manufacture above one tonne per year. The substance falls under CLP regulation for classification and labeling as evidenced by its GHS09 pictogram and Warning signal word. It is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with environmental regulations due to its aquatic toxicity classification. Additional restrictions may apply depending on specific applications, particularly in cosmetics where UV filters are regulated.
