When hair meets water that has interacted with surfactants, it creates a party where everyone's invited, including sebum, dirt, grime, Gary from down the hall.

当头发遇到与表面活性剂相互作用的水时，就像一个每个人都被邀请参加的派对，包括皮脂、污垢、灰尘，有走廊尽头的Gary。

Most are regular pneumocytes called type I pneumocytes, but some, called type II pneumocytes, have the ability to secrete a substance called surfactant, which helps decrease the surface tension within the alveoli and keeps them open.

大部分为I型肺泡，有一些为II型肺泡可以分泌一种表面活性剂，这有助于降低肺泡内的表面张力，并保持它们的开放。

Surfactants are the soapy part of the shampoo.

表面活性剂是洗发水的肥皂成分。

Agriculture is just one use for organosilicone surfactants. It's all over the place.

“不仅仅是农业应用有机硅表面活性剂。各个地都在用这种。

Preemies' lungs haven't yet developed enough of these surfactants, so the small alveoli squeeze too much and collapse, while the larger ones keep blowing up and get distended.

早产儿的肺没有生长出足够的表面活性剂，所以小的肺泡因挤压出太多的气体而塌陷，而大的肺泡则不断膨胀。

These adjuvants do not contain any active spray ingredients but consist of other chemicals, such as surfactants, emulsifiers and oils, which can improve the ability of a spray to remain on and penetrate leaves.

这些佐剂不含任何活性喷雾成分，但由其他化学成，例如表面活性剂、乳化剂和油，可以提高喷雾保留在叶子上和渗透叶子的能力。

There's been a lot of research done on this and broadly speaking, they think the active surfactants in espresso are probably things like melanoidins, a protein derived, roasting byproducts.

这面有很多研究，一般来说，他们认为浓缩咖啡中的活性表面活性剂可能是黑素，一种蛋白衍生的烘焙副产品。

It's then sent to the " De-inker" , which is another bath containing air bubbles and soap-like chemicals called surfactants that separate the paper from the ink.

然后纸浆再被送到“脱墨池”，是另一种池子，里面含有气泡，和与肥皂相似的化学——表面活性剂将纸从墨水中分离出来。

This creates a thin surfactant layer that helps prevent fogging.

这会形成一层薄的表面活性剂层，有助于防止起雾。

Now, in espresso, there are a lot of different compounds that are surfactants.

在浓缩咖啡中，有很多不同的化合都是表面活性剂。

But in healthy people, alveoli stay properly inflated because they're full of chemicals called pulmonary surfactants that make the small alveoli more stretchy and less squeezy, balancing the pressure between air sacs.

但在健康的人体内，肺泡会适当的保持充气状态，因为肺泡中充满了一种叫做肺表面活性剂的化学，这种能使小肺泡更有弹性，挤压力度更小，从而平衡气囊之间的压力。

The chemical in question is known as an organosilicone surfactant.

上文提到的化学是一种有机硅表面活性剂。

Some surfactants create more suds than others, but… Foam actually doesn't dictate how well a shampoo is cleaning your hair.

有些表面活性剂会产生更多的泡沫，但是… … 泡沫实际上并不能决定洗发水清洁头发的效果。

Hard water, for example, has higher mineral and deposit content that can overwhelm a surfactant, so other chemicals have to be added to the shampoo to counteract the ions that make the surfactants ineffective.

例如，硬水含有较高的矿和沉积，可以压倒表面活性剂，因此必须在洗发水中添加其他化学来抵消使表面活性剂失效的离子作用。

I believe that they are using this as their primary surfactant, and the cocamidopropyl betaine is the secondary surfactant in this formula.

我相信他们用这个作为主要的表面活性剂，椰油酰胺丙基甜菜碱是这个配中的次要表面活性剂。

In fact, caffeine at a high enough concentration will act as a surfactant, but it isn't really playing a role here.

浓度足够高的咖啡因会起到表面活性剂的作用，但在这里它并没有真正发挥作用。

I see sulfates as a great surfactant when used in moderation, and they're also being formulated in conjunction with other conditioning agents that allow it to moisturize and condition the hair at the same time.

我认为硫酸盐在适度使用时是一种很好的表面活性剂，它们也可以与其他调理剂一起配制，同时保湿和调理头发。

Generally speaking, a foam is a bunch of air bubbles trapped in a liquid and something in that liquid is called a surfactant, a surface-active agent.

一般来说，泡沫是一堆被困在液体中的气泡，液体中的被称为表面活性剂，一种表面活性剂。

Half of each surfactant wants to dissolve in water, and the other half wants nothing to do with H2O.

每个表面活性剂的一半想要溶解在水中，而另一半则与水毫无关系。

Finally, I return to the salon to tell you that baby shampoos are just shampoos that use milder surfactants and don't have special polymers or moisturizing agents, as matter of surfact.

最后再告诉你一件事，婴儿洗发水只使用了温和的表面活性剂，没有特殊的聚合或保湿剂，作为表面活性剂。
