Personal care products (PCPs) are integral components of daily human existence, including a large number of chemicals intentionally added for functional attributes (e.g., preservatives and fragrances) or unintentionally present, such as plasticizers. This investigation aimed to optimize the methodology for target and suspect screening via liquid chromatography-high-resolution mass spectrometry, focusing on nine prevalent organic additives (comprising bisphenols A, F, and S, methyl, ethyl, propyl, and butylparaben, 5-chloro-2-methyl-4-isothiazolin-3-one, and 4-hydroxybenzoic acid). A total of 50 high-selling PCPs were purchased from the local online market as samples. In detail, PCP samples were classified into body washes, shampoos, hair conditioners, facial cleansers, body lotions, and moisture creams. For calibration, the quality assurance and quality control results demonstrated a coefficient of determination () surpassing 0.999, with detection and quantification limits ranging from 2.5 to 100.0 ng/g. For recovery experiments, replicate recoveries ( = 5) ranged from 61 to 134%. In purchased PCP samples, five of the nine target compounds were detected via a target screening. Methylparaben exhibited the highest concentration (7860 mg/kg) in a facial cleanser, which is known as an endocrine-disrupting chemical. A total of 248 suspects of organic additives were screened in PCPs, leading to a tentative identification of 9. Confirmation (confidence level 1) via reference standards was achieved for three suspects, while six were tentatively identified with a confidence level of 2. This two-step extraction methodology utilizing methyl -butyl ether and isopropyl alcohol enabled simultaneous analysis of diverse chemical groups with distinct properties.
个人护理产品（PCPs）是人类日常生活不可或缺的组成部分，其中包含大量有意添加的功能性化学物质（如防腐剂和香料）或无意存在的化学物质，例如增塑剂。本研究旨在优化通过液相色谱-高分辨率质谱进行目标物和疑似物筛查的方法，重点关注九种常见的有机添加剂（包括双酚 A、双酚 F、双酚 S、甲基、乙基、丙基和丁基对羟基苯甲酸酯、5-氯-2-甲基-4-异噻唑啉-3-酮和 4-羟基苯甲酸）。共从当地的线上市场购买了 50 种畅销的 PCP 作为样本。详细来说，将 PCP 样本分为沐浴露、洗发水、护发素、洗面奶、身体乳液和保湿霜。用于校准的结果显示，质量保证和质量控制的决定系数（）超过 0.999，检测限和定量限范围为 2.5 至 100.0ng/g。对于回收率实验，重复回收率（n=5）范围为 61%至 134%。在所购买的 PCP 样本中，通过目标筛查检测到了九种目标化合物中的五种。在洗面奶中检测到了最高浓度的甲基对羟基苯甲酸酯（7860mg/kg），这是一种内分泌干扰化学物质。在 PCP 中共筛查到 248 种疑似有机添加剂，初步鉴定出 9 种。通过参考标准对其中 3 种疑似物进行了确证（置信度为 1），对 6 种疑似物进行了 2 级确证。该两步提取方法采用甲基-丁基醚和异丙醇，可同时分析具有不同特性的不同化学物质。
