A simple method for the simultaneous determination of personal care product ingredients: galaxolide, tonalide, oxybenzone, 4‐methylbenzyliden camphor, padimate‐o, 2‐ethylhexyl methoxycinnamate, octocrylene, triclosan, and methyl triclosan in lettuce by ultrasound‐assisted extraction combined with solid‐phase microextraction followed by gas chromatography with mass spectrometry was developed. Lettuce was directly extracted by ultrasound‐assisted extraction with methanol, this extract was combined with water, extracted by solid‐phase microextraction in immersion mode, and analyzed by gas chromatography with mass spectrometry. Good linear relationships (25–250 ng/g, R2 > 0.9702) and low detection limits (1.0–25 ng/g) were obtained for analytes along with acceptable precision for almost all analytes (RSDs < 20%). The validated method was applied for the determination of personal care product ingredients in commercial lettuce and lettuces grown in soil and irrigated with the analytes, identifying the target analytes in leaves and roots of the latter. This procedure is a miniaturized and environmentally friendly proposal which can be a useful tool for quality analysis in lettuce.
