近日，知名網紅衛生巾品牌“棉密碼”旗下產品被曝光檢測出含有有毒有害物質硫脲。

根據消費者集體送檢的檢測報告來看，從2019年9月到2025年1月，多個批次的“棉密碼茶氧夜用衛生巾”、“茶氧日用衛生巾”等品類均檢出超高含量硫脲，其中一款“棉密碼櫻花·舒緩型衛生巾”的硫脲含量甚至高達16653.4679μg/g。

A consumer-led inspection revealed dangerously high levels of thiourea in several batches of Mpassword sanitary pads produced between September 2019 and January 2025, including one product with concentrations exceeding 16,653.4679 μg/g.

硫脲，是一種在工業、農業、醫藥領域廣泛應用的含硫有機化合物，被列入《危險化學品名錄（2015）版》中，因其長期暴露可能導致較高的生物健康風險，被國際癌癥研究聯盟列為3類致癌物。

Thiourea is a sulfur-containing compound used across various industrial sectors and is classified as a Group 3 carcinogen by the International Agency for Research on Cancer (IARC).

專家介紹說，硫脲是一種中、低毒的化學品，急性毒性不高，但長期暴露可能導致較高的生物健康風險。在細胞和動物實驗上發現，硫脲可誘導甲狀腺功能障礙、肝毒性、生殖毒性以及免疫毒性。目前還沒有硫脲針對人體的系統化毒理影響評價研究，但考慮到硫脲暴露導致的對其他哺乳動物的復雜毒性，其作用于人體時推測可能也會發揮類似毒性效應，但尚需人群研究驗證。

Experts warn that although its acute toxicity is low, long-term exposure may trigger significant biological risks including thyroid dysfunction and reproductive toxicity, based on evidence from cellular and animal studies. While no comprehensive toxicological studies exist on thiourea's impact on humans, scientists caution that its documented harm to other mammals may suggest comparable risks to people.

硫脲有哪些危害

一份統計表顯示，有數百名“棉密碼”消費者曾提供產品使用后的反饋信息。有30余人自訴患有甲狀腺癌，同時反饋其他接觸硫脲的關聯病癥，均稱長期使用“棉密碼”衛生巾，并出示有多年購買“棉密碼”的訂單截圖。

A consumer database indicates that over 30 individuals reported developing thyroid cancer after prolonged use of Mpassword pads. Many shared screenshots of years-long purchase orders, citing additional thiourea-related symptoms such as hormonal imbalances and skin reactions.

統計表中，約35%的家庭中未成年女兒與母親長期共同使用“棉密碼”衛生巾；數百例消費者反饋紅腫瘙癢悶痘炎癥、婦科炎癥、皮疹蕁麻疹、甲狀腺功能異常、甲狀腺病變等硫脲關聯病癥；還有10例左右消費者自訴懷孕前使用“棉密碼”衛生巾，懷孕后出現了胎停、葡萄胎、新生兒甲亢等情況。

The data also revealed that in approximately 35 percent of families, both mothers and underage daughters regularly used Mpassword pads. Hundreds reported issues such as genital irritation, thyroid dysfunction, and autoimmune skin conditions. Around ten women claimed complications during pregnancy, including miscarriage, molar pregnancy, and neonatal hyperthyroidism.

“棉密碼”是頂流主播辛巴（辛有志）在2017年自創的品牌，號稱“辛巴親自參與研發的第一款產品”，也是辛選集團旗下自營品牌，辛巴曾在直播中自稱有1000萬用戶。

作為最早入局自營衛生巾賽道的電商品牌，“棉密碼”曾憑借精準的營銷定位成為直播平臺的現象級產品，辛巴更在直播中得意提及“每次發貨都要排隊”。

Launched in 2017 by livestreaming celebrity Xin Youzhi (known as Xinba), Mpassword was promoted as his first hands-on product and quickly rose to prominence as a flagship brand with a claimed user base of 10 million. Xinba frequently boasted in his broadcasts about the high demand and long shipping queues.

據信息時報，有業內人士稱，“棉密碼”8年時間累計銷售額高達33.3億元。2023年時，該品牌曾入駐超600家線下門店，覆蓋石家莊、中山等一二線城市，逐步推進全渠道布局。“棉密碼”多個產品系列號稱采用茶多酚衛生巾芯片，主打抗氧化的效果。然而，新京報記者調查發現，“棉密碼”衛生巾芯片正是檢出硫脲的重災區。

According to the Information Times, industry insiders revealed that Mpassword has achieved cumulative sales of 3.33 billion yuan over an eight-year period. The brand expanded into more than 600 physical stores across major cities like Shijiazhuang and Zhongshan, marketing its products as antioxidant pads featuring tea polyphenol "chip" inserts. However, investigations by The Beijing News have identified these very chip components as hot spots for thiourea contamination.

衛生巾芯片為何會檢出硫脲？專家分析稱，硫脲有抗氧化劑的典型特征，且其價格低廉，不排除可能人為添加硫脲以替代成本更高的抗氧化劑茶多酚。有業內人士透露，這在行業內已不是秘密。

Experts speculate that thiourea may have been deliberately added as a cheap substitute for tea polyphenols due to its antioxidant properties. Industry insiders suggest that such practices are well-known within the sector.

辛選回應：不存在致癌問題

據界面新聞，針對上述問題，辛選方面24日回應稱，“棉密碼”品牌第一時間請求汕頭市監部門對產品進行了抽檢，結果是合法合規合格的，并不存在“致癌”的問題。

辛選還向界面新聞提供了一份廣東省汕頭市質量計量監督檢測所出具的檢測檢驗報告。該報告的其中一個樣品名稱為“棉密碼茶氧日用衛生巾”，委托檢測日期為2025年5月13日。檢測結果顯示，所檢測的5個項目符合GB/T8939-2018《衛生巾（護墊）》和GB 15979-2002《一次性使用衛生用品衛生標準》的要求。報告中未檢出含有硫脲成分。

On Thursday, Xinxuan Group responded by stating that it had requested official testing from local regulators in Shantou, Guangdong province, which confirmed that its products met national standards and did not pose a carcinogenic risk.

而在其他送檢樣品中，包括棉密碼茶氧量大日用衛生巾、棉密碼茶氧夜用衛生巾、棉密碼茶氧迷你衛生巾等多個型號產品中，報告顯示的檢測結果均為符合前述相關標準，且無硫脲成分。7月24日，針對“辛巴自創品牌‘棉密碼’衛生巾檢出超高含量致癌物”的消息，“棉密碼”發表聲明稱“產品不存在致癌問題”。

Further testing of other Mpassword pads—including day-use, night-use, and mini pads—likewise reported no thiourea content. In an official statement on Thursday, the company reiterated that all products were compliant and underwent thorough third-party evaluations.

The statement emphasized that all products comply with national safety standards. It acknowledged public concern and noted that toxicological assessments showed no significant health risk under normal use. The company also initiated its own inspection through the local Shantou regulator, which confirmed the products as safe and compliant.

記者注意到，“棉密碼”衛生巾的生產方主要為廣東伊美潔生物科技有限公司。天眼查App顯示，該公司成立于2015年，位于廣東省汕頭市，是一家以從事化學原料和化學制品制造業為主的企業，注冊資本為1000萬人民幣。

7月24日，汕頭市澄海區市場監管局工作人員回應南都灣財社記者稱，相關部門正在調查此事，有后續結果會官方公布。南都灣財社記者致電涉事品牌生產商廣東伊美潔生物科技有限公司，但被對方以“現在正忙”為由掛斷電話，此后電話未能接通。
