干燥寒冷的冬季,选择一款什么样的润唇膏是许多女性消费者关心的问题,而保湿效果则是消费者购买润唇膏时必然考虑的因素。在润唇膏的保湿效果中,维生素E(VE)的保湿作用又一直都是企业宣传的重点。不过,这些产品中到底是否含有VE,含量多少,普通消费者很难知晓。
近日,有媒体对市售的曼秀雷敦、惠氏、EOS、科颜氏、妮维雅等5个常见润唇膏品牌进行了品质和安全性检测。由于一些消费习惯的转变,此次检测还包括网上比较受欢迎的手工制品品牌莫瑞花园的润唇膏产品。
检测结果显示,惠氏护唇啫喱与手工制品莫瑞花园茉莉花桂花润唇膏未检出其宣称的VE成分。同时,2013年投放了大量广告的EOS润唇膏VE含量最低。
润唇膏作为保护嘴唇水分丢失的屏障,其基本成分为凡士林和蜡质。“维生素E在润唇膏中可以对皮肤起到保湿滋润的作用。”广东省保化检测中心工程师陈科说。
此次送检的7款产品,均在产品包装上注明含有维E。惠氏和莫瑞花园两款未检出维E的产品中亦标榜自己含有维E成分。
事实上,根据检测结果显示,由舒淇代言的曼秀雷敦天然植物系列润唇膏VE含量也只有0.059%。而其他几个产品的维E含量差异较大。
深圳出入境检验检疫局技术人员李英曾表示,VE可以起到保护皮肤水分,防治皮肤色素沉着,防皱等作用,且又是很好的氧化剂。
事实上,即便在本刊检测中VE含量最高的一支15mL的科颜氏润唇膏中,也只有0.63%。这么少的含量,在润唇膏中真的能起到保湿的效果吗?
欧莱雅交流合作事业部姚颖表示,VE对于皮肤的呵护功能已经得到大量科学数据的验证,因而被广泛用于许多护肤品的配方中,包括润唇膏。至于在某一配方中VE的具体含量,必须视该产品的配方要求及其需要达到的功效而进行针对性的设计和开发。
中国香精香料化妆品工业协会秘书长张京原表示,“VE确实对人体有好处,但具体达到多少才能有好处,在这方面,我们并没有一个确切研究成果,所以不能下结论。”
目前,市场上的润唇膏价格从十几元到几十元不等,在淘宝中甚至有自制1元的润唇膏。企业是否存在为了节省成本而偷工减料的情况?
对此,广东省疾控中心毒理所所长熊习昆透露,“润唇膏的主要成分是蜡质、脂肪,而造成这些差价的原因,也是原料不同。还有就是用户体验感觉不一样。从成本上来说,价格高的产品,其原料也相对较好一些。”
