1,1-Dimethylethyl 4-hydroxybenzoate

Description:

1,1-Dimethylethyl 4-hydroxybenzoate, also known as tert-butyl paraben, is an organic compound commonly used as a preservative in cosmetics and personal care products due to its antimicrobial properties. It belongs to the paraben family, which are esters of p-hydroxybenzoic acid. This compound is characterized by its white crystalline solid form and is soluble in organic solvents while being less soluble in water. Its chemical structure features a tert-butyl group attached to the hydroxyl group of the benzoate, which enhances its stability and efficacy as a preservative. The compound exhibits low toxicity and is generally recognized as safe for use in regulated concentrations. However, like other parabens, it has been the subject of scrutiny regarding potential endocrine-disrupting effects, leading to ongoing research and regulatory evaluations. Overall, 1,1-Dimethylethyl 4-hydroxybenzoate serves as an effective preservative, balancing functionality with safety in various applications.
