Cosmetic chemistry.

It belongs to fine chemical industry.Ye Changling's understanding of it is also limited to some substances.Such as glycerin, niacinamide, urea, vitamin C and the like.Urea is a very important substance in compound fertilizers. After the nitrogen fertilizer was successfully produced, Ye Changling also took it into consideration.

Or he should have considered urea long ago.

With the preparation basis of ammonium sulfate, the process of preparing urea is much simpler.The finished product is already available, but it is still in the experimental stage, and it is winter, so there are too many things to do.Instead it was shelved.

Now, it is just right to use it in advance.

Thinking so, Ye Changling went into the study, wrote a note, handed it to Chen Si, asked him to go to Zhuangzi, handed the note to Old Craftsman Zhang, and asked Chen Si to bring over the things he needed.

Niacinamide... With his current poor industrial level, he should give up honestly.But glycerin... When making soap, there are still a lot of by-products such as triglycerides.

Just as Ye Changling wanted Chuntao to take out the small bucket of glycerin that was left in the room before, he remembered that Chuntao had left the capital now.Looking at the little girls in the yard again, the only older ones, Qiu Xing and Mei Xiang, had thin arms and legs, not as tall as his shoulders.

Well, he'd better get it himself.

After entering the room, I took out the small bucket of glycerin from under the bed and put it on the table. When I opened the lid, it smelled okay, after all, it was sealed and stored at the beginning.

After taking glycerin, Ye Changling took out an old clothes from his cabinet by the way.

After Mei Xiang became the housekeeper, Ye Changling's living standard has improved linearly. For example, his clothes are all made of high-quality silk.

The newly hired embroiderer in the house is even more extraordinary. Ye Changling picks and chooses. Fortunately, until the New Year's Eve, he was still keeping his filial piety. His clothes are very plain. It is not easy to find a white dress with no color.

Ye Changling planned to make a mask.

But with the materials and scissors in hand, Ye Changling couldn't do anything.In the end, it was Mei Xiang who saw the hesitation on her young master's face, so she took the scissors and clothes, and cut out a mask according to Ye Changling's thinking.

The ingredients of the mask are even simpler, water, glycerin, and some bayberry juice, aloe vera juice, etc., the finished product is very unsightly.

Sure enough, it failed.Ye Changling was indifferent.

Looking at the bad color and strange smell, the little maids on the side were very hesitant.

Ye Changling put the mask on Mei Xiang's face.

Mei Xiang: ...

For Mei Xiang today, many matters in the Ye Mansion, the business under the name of the young master, and the fertilizer factory that the young master attaches great importance to, are too much for adults to bear, and Mei Xiang still needs to take time out every day on this basis. , while studying, Ye Changling felt that he could not see Mei Xiang more and more, but he didn't know that the little girl could not even maintain enough sleep every day.

Mei Xiang was already mentally prepared for being smeared with a strange face by the young master.Anyway, appearance is not important to her, or rather good looks have become a burden to her.

But to Mei Xiang's surprise, the white satin stained with a strange liquid stuck to her face, it was cold and comfortable.

Mei Xiang was dragged by Ye Changling and sat down on the old man's chair beside her.Leaning on the young master's chair, Mei Xiang obeyed the young master's instructions, closed her eyes and waited for the time to pass...

Mei Xiang woke up suddenly.

She slept for a long time.

The setting sun shone in the small courtyard, and the things on her face were taken away at some point, Mei Xiang touched her face subconsciously, probably because of her illusion, the skin felt smoother.

Not far away, the young master is surrounded by a large circle of little maids, and the young master is doing 'juggling' for them.These 'tricks' Mei Xiang has seen the young master change many times in Zhuangzi before.She was not very interested, but the group of chattering little maids liked it very much.

"Master, do you mean that we can learn these things from Master tomorrow?" Qiu Xing looked at Ye Changling and asked cautiously.She heard many new terms today, and also knew many things that she had never heard of before.

For example, the bucket of 'glycerin' that the young master took out can 'moisturize' and 'skin care' when rubbed on the face.

For example, the stinky 'urea' can be used as fertilizer, or it can be applied on the face for 'skin care' and 'whitening'.

For example, the earth is actually round, and the sun is also round. They are far, far away, and the earth under their feet is actually revolving around the sun.

For example, Jade's illness was caused by eating lead powder, which is a bad 'metal' for people, and their usual cold and previous smallpox were due to some tiny 'bugs'.

"Naturally..." Ye Changling nodded, but then hesitated again.After all, he had other things to do, and these little girls were innocent and asked wildly unconstrained questions.

Ye Changling's hesitation caused Qiu Xing to misunderstand immediately.

Just when Qiu Xing was disappointed, she heard the young master speak suddenly.

"Well, starting tomorrow, you all will go to Zhuangzi with me. There are some things that others can teach you." For example, Cheng Zhongyu, Zhang Laojiang and the others, along with half of Fang Yaoyi.
