2-Ethylhexyl 4-hydroxybenzoate

Description:
2-Ethylhexyl 4-hydroxybenzoate, with the CAS number 5153-25-3, is an organic compound commonly used as a UV filter in sunscreens and cosmetic formulations. It is characterized by its ester structure, derived from the reaction of 4-hydroxybenzoic acid and 2-ethylhexanol. This compound is known for its ability to absorb ultraviolet radiation, particularly in the UVB range, thereby providing protection against sun-induced skin damage. It is typically a colorless to pale yellow liquid with a mild odor and is soluble in organic solvents but has limited solubility in water. In formulations, it enhances the stability and efficacy of other UV filters and is often combined with other ingredients to achieve broad-spectrum protection. Additionally, 2-Ethylhexyl 4-hydroxybenzoate is considered to have low toxicity and is generally regarded as safe for use in cosmetic products, although regulatory assessments may vary by region. Its stability under sunlight and heat makes it a preferred choice in various personal care applications.
