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。

2005年,CIR專家小組審議了有關DMDM乙內酰脲的新數據,在目前的使用方法中作為化妝品成分是安全的。
CIR安全審查:DMDM乙內酰脲很難從皮膚吸收。在實驗室研究中,口服DMDM乙內酰脲並不引起任何不良反應。CIR專家小組指出,DMDM乙內酰脲是水性介質中的甲醛供體。他們將一些體外誘變性研究的積極結果歸因於甲醛釋放。在這些研究中,所測試的DMDM乙內酰脲的濃度高於化妝品和個人護理產品中所用的濃度,這可能導致甲醛濃度遠高於產品中的甲醛濃度。臨床研究顯示一些皮膚刺激性觀察,也可能與DMDM乙內酰脲釋放甲醛有關。

CIR專家小組審查了化妝品和個人護理產品中甲醛的安全性,並得出結論認為,甲醛對大多數消費者而言是安全的,但由於某些人對這種試劑的皮膚敏感性,其濃度限制為游離甲醛的0.2%。保存產品所需的DMDM乙內酰脲(少於1%)不會使消費者暴露於CIR專家小組建議的甲醛濃度超過0.2%限值的甲醛濃度。
可以用於化妝品和個人護理產品,最大濃度為0.6%。如果成品中釋放的甲醛濃度超過0.05%,則必須標記為“含有甲醛”。

Dimethylol-dimethyl (DMDM) hydantoin is a chemical used in a wide range of cosmetic products. DMDM hydantoin is an antimicrobial formaldehyde releaser (mean it released side product "formaldehyde" that is carcinogen) preservative with the trade name Glydant. DMDM hydantoin is an organic compound belonging to a class of compounds known as hydantoins. It is used in the cosmetics industry and found in products like shampoos, hair conditioners, hair gels, and skin care products. DMDM hydantoin has come under fire in recent years, mainly because it releases small amounts of formaldehyde. This chemical helps prevent your products from going bad, but at high doses, it may have the potential to cause cancer in humans .
According to scientific experts, DMDM hydantoin is safe as a cosmetic ingredient at normal levels of use in products," says Friese. And according to the Cosmetic Ingredient Review, it's safe to use DMDM hydantoin as a cosmetic ingredient at levels of 0.074% or less. Despite of this, this is better to avoid its usage.

(歷史訊息)認識化粧品防腐劑-甲醛釋放型防腐劑

提到甲醛,很多人的疑問是:「甲醛不是人類可能的致癌物質嗎?化粧品可以使用會釋放甲醛的防腐劑嗎?」,其實自然界中本來就存在微量甲醛,大部分動植物在新陳代謝及微生物天然發酵過程中,都會產生微量甲醛,包括蔬菜、水果、魚類、甲殼類及蕈菇類,天然發酵產品如啤酒等也都含有微量的甲醛。化粧品的水含量高又富含有微生物生長所需的養分,很容易受到微生物汙染而變質,再加上夏季高溫炎熱,所以為了能夠在室溫下貯放一定時間,業者會適度添加防腐劑,來防止產品腐敗以確保產品品質。

目前衛生福利部公告可以使用在化粧品的防腐劑共有47種,其中包括二羥甲基二甲基乙內酰脲(DMDM Hydantoin)、咪唑烷基脲(Imidazolidinyl urea)、季銨鹽-15 (Quaternium 15)、溴硝丙二醇(Bronopol)、雙烷基咪唑脲(Diazolidinyl Urea)、羥甲基甘氨酸鈉(Sodium hydroxymethylglycinate)、烏洛托品(Methenamine)、甲醛苄醇半縮醛(Benzylhemiformal)等9種甲醛釋放型防腐劑。

依我國管理規定,化粧品使用甲醛釋放型防腐劑之成分作為防腐劑時,其總釋出之游離甲醛(Free Formaldehyde)量,不得超過1,000 ppm,針對含甲醛釋放型防腐劑的化粧品,衛生福利部食品藥物管理署每年都會進行甲醛釋出量的監測,檢驗結果均符合公告限量,因此消費者毋須過度驚慌。

提醒民眾在選購化粧品時需注意產品標示、保存方式、有效期限,避免購買來源不明、標示不清之產品,並看清楚產品的使用方式及注意事項,依標示正確使用產品,適時諮詢專業人員,才是維持美麗的小秘訣。有關化粧品內含有甲醛釋放型防腐劑之相關限量使用規定可至食品藥物管理署網站(首頁http://www.fda.gov.tw/TC/index.aspx>業務專區>化粧品>化粧品相關法規>化粧品中防腐劑成分使用及限量規定)查詢。
