既然此成分屬於低度皮膚過敏危險性,那為何在安心度評分表中還亮紅燈呢?應該要很安心才對啊!

因为是释放甲醛呀!另外本身护肤品就不应该含有能引起低度皮膚過敏危險性的物质,即使是防腐剂的微量级别长期使用也是有危害的。如果用的是一个系列都添加DMDM的产品,危险性自然就成倍上升啦~

联合利华旗下的“力士”、“多芬”洗发乳近日被曝光检出致癌的游离甲醛。昨天,联合利华通过官方微博声明称其洗发水配方中从不添加甲醛,检出的甲醛来自“DMDM乙内酰脲”,在中国及欧美标准均允许使用,该物质的含量及释放出的游离甲醛量均符合中国标准。
台湾“消基会”在最新发布的一则25件抗屑、止痒、生发洗发精功能测试中提到,化妆品中使用DMDM Hydantoin等成分作为防腐剂时,其总释出之游离甲醛含量不得超过1000ppm。而力士柔亮洗发乳、Dove(多芬)去屑护理洗发乳以及舒妃有机草本萃取洗发乳的成分中含有DMDM Hydantoin,并检出游离甲醛,但释出量均合乎当地化妆品卫生管理条例规定。
联合利华昨天表示,其洗发水配方中不添加甲醛,检测产品中所释出的游离甲醛主要来自DMDM乙内酰脲。DMDM乙内酰脲有助于产品储存及防止微生物污染,力士和多芬洗发水在欧美和中国市场均使用该成分。
声明还表示中国市场销售的所有力士、多芬洗发水中DMDM乙内酰脲成分含量及释放出的游离甲醛量均符合中国的标准。有专家指出,生产企业有责任和义务将产品所含的有害化学物质含量在外包装上明示,并注明是否存在健康隐患,以保障消费者的知情权。(记者杨滨)

DMDM hydantoin is an antimicrobial agent and preservative. It increases the shelf-life of cosmetics (e.g. shampoos, skincare products, hair gels, etc) by "releasing" formaldehyde and thus killing bacteria. This keeps cosmetics sanitary, and prevents illness due to infections.

The Environmental Working Group (EWG) lists the hazard level of DMDM hydantoin at moderate/high. It is not known to cause developmental and reproductive toxicity, and has a low risk of being a carcinogen. The chemical may be a problem in people who are allergic to formaldehyde, and can increase the risk of developing a formaldehyde allergy. The most common type of allergy is a skin allergy.

As of 2005 however, the independent Cosmetic Ingredient Review panel (established in 1976) lists DMDM hydantoin as a "safe" ingredient [2]. The benefits outweigh the risks, especially at the low levels that are found in most cosmetics:

"The CIR Expert Panel has reviewed the safety of formaldehyde in cosmetics and personal care products and concluded that it was safe to a great majority of consumers but has limited the concentration to 0.2% free formaldehyde due to the skin sensitivity of some individuals to this agent. The amount of DMDM Hydantoin required to preserve a product (less than 1%) does not expose the consumer to concentrations of formaldehyde above the 0.2% limit for formaldehyde recommended by the CIR Expert Panel."

So unless someone is very sensitive to formaldehyde, this is a generally safe chemical. It is poorly absorbed by the skin, and there are no adverse effects from oral exposure [2]. Nevertheless, when finding toiletries (e.g. baby wipes, sunscreen, etc) for babies and young children, it might be a good idea to stick to preservatives that are associated with fewer complications.

甲醛可能令部分人士產生皮膚刺激反應,美國接觸性皮膚炎協會(ACDS)更將甲醛列為2015年的「年度致敏物質」。有研究指,較高濃度的甲醛(200至300ppm)可致皮膚炎,如有傷口、易敏感皮膚或濕疹人士更要小心。
