据一份2008年由英国明泰尔市场调查公司开展的调查报道,一半的成人感到洗发水和护发素的种类繁多,让人眼花缭乱。潘婷作为洗发水类中的龙头老大,旗下就有14种以不同功效为主题的系列,总共113种产品。不难看出洗发水的货架上挤满了不同洗发水产品,让人不知从何下手。但是这些洗发水的成分到底是什么,它们有什么作用呢?我们就对写在洗发水瓶子后面的成分细细分门别类吧。
  Therersquo;s no shame in admitting that your hair affects your mood. According to a Dove Hair Care survey, one out of every four women has avoided an activity due to unruly hair and 88 percent say good hair boosts their confidence. So for many women, a trip to the shampoo aisle is a much more serious purchase than stocking up on toothpaste and Q-tips.
  承认吧,三千烦恼丝影响着你的情绪。这没什么可难为情的。据一份多芬头发护理调查显示,每四位女***中就有一位曾因为一头乱蓬蓬的头发而缺席一项活动。百分之八十八的女***说,一头秀发能让她们自信满满。因此对于很多女***,在货架上挑选洗发水比起购买牙膏和棉签来可是一件严肃的大事。
  A 2008 study from market research firm Mintel reported that half of adults find the variety of shampoos and conditioners overwhelming. When Pantene, the shampoo category leader, offers 113 products in 14 different benefit-themed lines, itrsquo;s easy to see how the shelves have become so crowdedmdash;and confusing.

  The good news? The majority of those options boil down to different packaging. ldquo;All shampoo is essentially a cleanser,rdquo; says Paula Begoun, author of Beautypedia.com. ldquo;Only the first five or six ingredients impact the formularsquo;s effectiveness.rdquo; And if you do a quick survey of a few shampoo ingredients labels, yoursquo;ll quickly see how the top 10 list looks nearly the same on all of them.
  这是一个好消息吗?在这些种类繁多的产品中,大部分归根到底不过是包装不同。Beautypedia.com网站的撰稿人宝拉middot;贝岗说道:ldquo;所有的洗发产品基本上都是一种清洁剂。只有前5到6种成分影响到洗发水配方的效果。rdquo;如果快速浏览一些洗发水标签上的成分,你很快就会发现所有标签上写的前十种成分看起来几乎都差不多。
  But what are those ingredients, and what do they do? We broke down the ingredients on the back of the bottle.
  但是这些成分到底是什么,它们有什么作用呢?我们就对写在洗发水瓶子后面的成分细细分门别类吧。
  1. Water. Up to 80 percent of shampoo is this basic element. Without enough of it, the lathering liquid wouldnrsquo;t pour from the bottle.
  1.水。这种基本成分在一瓶洗发水中高达百分之八十。如果没有足够的水,这些气泡的液体就无法从瓶子里倒出来了。
  2. Surfactant. Basically a detergent, this additive does the bulk of the work. Surfates clean by surrounding dirt and oil so water can rinse them away. Ingredients like ammonium lauryl sulfate and ammonium laureth sulfate tend to be easier on sensitive scalps than sodium lauryl sulfate. Rumors that these chemicals can cause cancer are unfounded. While surfactants are irritating, shampoos don't contain high-enough levels to cause any real damage. Surfactants arenrsquo;t a problem unless you have sensitive skin or insist on regularly pouring gallons of the stuff in your eyes. And the cleansers shouldnrsquo;t be harmful to your hair. The shampoos sold today contain conditioners that compensate for the stripping qualities of surfactants, so you can wash daily without worry.
  2.表面活***剂。基本上就是一种清洁剂。这个添加剂起的作用最大。它把周围的污垢和油脂溶解。然后清水就能将它们冲洗干净。像十二烷基硫酸铵和十二酯硫酸铵这样的成分比十二烷基硫酸钠更容易被敏感头皮接受。有传闻说这些化学成分能致癌,完全是无稽之谈。虽然表面活***剂有刺激***,但是洗发水里成分浓度不高,不会造成任何实际伤害。除非你是敏感***肤质或者你坚持定期将洗发水几加仑地往眼睛里倒,表面活***剂就不会带来什么问题。现在销售的洗发水中都含有护发素,这就能弥补表面活***剂的剥离特***。所以你可以放心地每天洗头
  3. Foaming agents. Ingredients like cocamide or cocamidopropyl betaine provide the satisfying suds that complete the hair-washing experience. Lather, however, is purely aesthetic. ldquo;Lather doesnrsquo;t have anything to do with how well a shampoo works,rdquo; says Nirsquo;Kita Wilson, a cosmetics chemist for Cosmetech Laboratories. ldquo;Manufacturers put lathering agents in shampoos because itrsquo;s what consumers expect.rdquo;
  3.发泡剂。如椰子酰胺和椰油酰胺丙基甜菜碱这样的成分能够带来丰富泡沫。这些泡沫圆满了整个洗头发的体验过程。然而,泡沫仅仅是审美上的需要。一位Cosmetech研究所的化妆化学家尼middot;基塔middot;威尔逊说道,ldquo;泡沫和洗发水的功效完全没有关系。制造商在洗发水中加入发泡剂,不过是为了满足顾客的期望
  4. An acidic ingredient. Items like sodium citrate or citric acid on your shampoo label are added to keep shampoo at the right pH level. The acidic pH interacts with the hair's slightly negative charge to help the cuticle, the outer layer of the hair, maintain a smooth, flat surface.
  4.一种酸***成分。你的洗发水标签写着的如柠檬酸钠或者柠檬酸成分。加入这些成分是为了使洗发水保持合适的PH值。酸***PH值和头发上的微量的负电荷相互作用,以此来帮助毛小皮,即头发表面的一层,保持表面光滑平整。
  5. Silicones like dimethicone, or anything ending in 'one.' These are polymers that deposit a lightweight coating on the hair. They help create smoothness and add shine.
  5.硅树脂,如二甲基硅油,或者任何以ldquo;onerdquo;拼写结尾的物质。这些聚合物在头发上形成一层轻薄的保护膜。它们有助头发顺滑,增加发质光泽。
  6. Polyquaternium. Much like a fabric softener, it helps make hair more manageable by depositing a fatty conditioner and fighting static. It also thickens the shampoo formula so itrsquo;s easier to pour.
  6. 聚季铵盐。 和织物柔顺剂很相似,它能形成一层脂肪状的护发素,赶走静电,让头发更易打理。它也增稠洗发水配方,这就更容易倒出来。
  7. Panthenol, fatty alcohols, and nut oils. These common additives moisturize and lock in hydration.
  7. 泛酰醇,脂肪醇和坚果油。这些常见的添加剂能增加并锁住水分。
  8. Midazolidinyl urea, iodopropynyl, isothiazolinone, and sodium benzoate. ldquo;Unless you want your shampoo to grow legs and walk away, you need preservatives,rdquo; Wilson says. Since many of the other ingredients are made from organic materials, they can grow mold and bacteria. These additives keep your shampoo from turning into a science project.
  8. 尿素醛,碘代丙炔基氨基甲酸丁,异噻唑啉酮和苯酸钠。ldquo;如果你不想让你的洗发水长腿跑掉,你就需要防腐剂。rdquo;威尔逊说道。由于很多其他成分是由有机材料制成,它们会发霉,滋生细菌。这些防腐剂就能防止让你的洗发水变成一个科学实验。
  ldquo;Most often, the ingredients lower down on the list arenrsquo;t present in high-enough concentrations to have any impact on the shampoorsquo;s performance,rdquo; Begoun says. Natural extracts and other additives that manufacturers brag about on the label donrsquo;t do much for your hair, but they might make the experience more enjoyable by adding a little color or fragrance to the process. Of course, judging by the number of women (and men) sniffing shampoo in the personal-care aisle of the drugstore, fragrance is a big part of the shampoo equation. To wit: the phenomenon that was Gee, Your Hair Smells Terrific.
  ldquo;多数情况下,排名靠后的成分由于没有足够的浓度,不会对洗发水的功效产生影响。rdquo;贝岗说道。制造商在标签上大力吹嘘的天然提取物和其他添加剂对你的头发并没什么用处。但是通过在过程
