Jiang Nian has been engaged in daily chemical for the past two years, and has gradually touched a little bit of the industry.

There are two main factions of sun protection.

The first is physical sun protection.

Physical sunscreen is generally composed of titanium dioxide, zinc oxide and some IQ taxes, which is equivalent to scraping a layer of putty on the face to cover the skin.

The principle of this idea is simple, but the problem is that the burden on the skin naturally increases after applying a layer of putty to yourself, and because of the addition of titanium dioxide and other things, the skin will not be normal.

The most critical problem is that it is very troublesome to remove makeup after use, and you have to carefully clean it with makeup remover to get off the pile of strong adhesive putty on your face, which is very unfriendly to sensitive skin.

The second is chemical sunscreen.

Theoretically, the upper limit of chemical sunscreen is higher, and many big names are rolling this idea.

But the problem of chemical sunscreen is more obvious - the technical requirements are high, and a little bad or a little storage expired will cause great damage to the skin, and oiliness or something is very common.

Take the simplest chestnut -

There is a very powerful chemical sunscreen ingredient called avobenzone (butyl methoxydibenzoylyl), which is one of the few sunscreens that can absorb 2 at the same time. (UVA reaches 95% of the earth's surface, and decades later, further research has confirmed that UVA is not only a major cause of skin photoaging, but also involved in the process of sun-induced cancer.) ）

But as a sunscreen, the photostability of this thing is very poor (the principle can be understood as one for one with ultraviolet rays), and most of it will be damaged after an hour of sunburning, and this thing is also easy to dye yellow clothes, and a little carelessness will bring some bad impressions to people who don't know the truth.

So since the end of the 80s, everyone has been looking for a substitute for this thing, and once found a replacement for it DHHB (diethylamino hydroxybenzoyl hexyl benzoate).

But just when everyone abandoned avobenzone and embraced DHHB, everyone was surprised to find that in fact, this thing was beaten by the ancestral avobenzone in the entire 290-400 nm band, so the major brands turned back like scumbags, crying back to find their own avobenzone, and began to add some stabilizers to this not very good-tempered product.

But in this way, there is a problem, adding a stabilizer is to add one more chemical ingredient, which greatly increases the chance of allergies, resulting in a lot of speechless experiences.

Moreover, in the traditional concept of Chinese people, chemistry represents danger, and only pure nature represents health, which is the direction that can be pursued.

Jiang Nian directly put chemical sunscreen on the bright side, which can immediately dissuade a large number of consumers.

Well, it has gathered the right time, place and people, forming a quite perfect closed loop, and this is the idea put forward by Ms. Jin, if it fails for a long time, it can at least prove that the problem is very big.

Whew, time is running out, and I have to make this decision in order to form a loss within this year.

Wu Xuejun looked confused, and the expression on his face was ugly than crying.

He felt like a stupid student in his class who put in a lot of effort but didn't study well.

The others have learned one or two layers of Xiao Jiang's skills, and now they can take charge on their own, and although they continue to work hard as a veteran student, the gap between them and Xiao Jiang is still very different.

It's over, what is Xiao Jiang always thinking about?

The so-called residence migration qi, nourishment migration body.

Although Jiang Nian has been bent on losing money in recent years, he is an entrepreneur who orders everyone after all, and now Jiang Nian is no longer a 22-year-old natural girl, and she exudes a temperament that cannot be rejected by anyone who has the overall situation in hand.

She temporarily added this column to the company's annual plan without consulting the board of directors and other vice presidents before, which is enough to show the courage of Mr. Jiang.

And what they want to challenge is a very high-tech sunscreen, or it is pressed on my old martial arts.

What a burden this is.

"I, I do my best, hopefully...... I hope to live up to Mr. Jiang!"

Jiang Nian was satisfied

Nodding, he said with a little guilt:

"That's good, then rely on Mr. Wu's efforts."

Seeing Wu Xuejun away, Jiang Nian immediately dialed Wen Qing's phone and said in a sweet and greasy voice:

"Mom!"

Wen Qing was so happy when he heard Jiang Nian say curiously:

"What's the good thing?"

"Hehe, it's nothing, I'm glad I can't give you a call?

We're going to launch a new product, and when the time comes, let the master give us the work."

Wen Qing smiled and said:

"Isn't that a matter of course, kid? When will a new product be released?"

"It's going to be on the market in August, and we're doing sunscreen this time!"

"August!" Wen Qing was slightly surprised, "Isn't it the end of June? When are you going to start getting sunscreen?"

Yangfan Daily Chemical takes the high-quality route, and buys raw materials to keep improving.

That is to say, they are going to start production from now on, but now they don't even understand the basic formula and product route.

Can that thing really work in the military daily chemical factory before?

Jiang Nian said triumphantly:

"Oh, don't you have to rely on the magic of my mom and dad's investment gods?

Mom, you don't have confidence in me, and you can't have confidence in yourself! You're the person I admire the most!"

Wen Qing couldn't hear her daughter's yin and yang weirdness, and nodded when she heard the words, and smiled with crooked eyebrows:

"Okay, that's no problem, if you need your mother to help you other than ask the master, just say!"

Jiang Nian: ......

I just casually flattered you, and you really believed it.

"If you have time, you can get your script as soon as possible, and after you finish it, let Director Lin hurry up and start selecting actors according to the script or something, whether the company can make a lot of money instantly depends on my mother's clever pen!"

Wen Qing was silent on the other side of the phone for a moment, and finally said a little cautiously:

"Niannian, what if, I mean, if Mom's script doesn't work?"

"How could it not be? My mother finished junior high school that year, and this is such a level of education that it is not easy to write a script."

"Ahem, your mother has already completed high school by herself, don't say that your mother has a junior high school education in the future."

"Okay, okay." Jiang Nianmei smiled, comforted Wen Qing a few more words, and then hung up the phone proudly.

Hehe, within a month, the sunscreen is made and my mother's script is released, and everything should be fine by then.

Jiang Nian stood up and looked out the window, feeling that the warm summer sun was particularly warm.

Hehe, this trick is like Zhou Yu forcing Zhuge Liang to make arrows without giving him materials......

Hey, no, it can't be compared like this, Zhuge Liang borrowed the arrow from the grass boat in the end, which is unlucky and unlucky!

Small Theatre Hours:

Jiang Nian: Theoretically speaking, both chemical and physical sunscreen have advantages and disadvantages, if you are not outdoors for a long time or when you are working by the window all day by the sun, there is no need to have too high requirements for sun protection, and the anxiety spread by a lot of propaganda is too terrible. In addition, let's talk about a little knowledge in the industry - often see reports that the use of a certain ingredient will have a bad impact on the body, in fact, this should also be carefully demonstrated, and there are also special big news abroad to criticize the chemical composition and then provide environmental protection certification to raw material suppliers. In this regard...... Uh, a game of chess around the world!
