Chapter 223 An epoch-making product

Song Ping has been so busy recently that his hind feet are not touching his front feet. 【】On the tenth day of the lunar new year, he realized that there were still many things to be done.People who have donated to the university before are invited.On the tenth day of the lunar new year, it is not just an inauguration ceremony, and it is over.According to Su San's idea, there will be another round of donations.There is also a work report and a vision for the future of the university.Originally Song Ping wanted to prepare the lunch banquet better, but this proposal was refuted by Su San.

Since it is a free school, it is wrong to eat and drink with the donor's money.This approach, although everyone does not say it on the surface, but secretly, there must be ideas.Even if it is human nature to have a meal, it is better not to set this precedent.If you really develop this kind of atmosphere, it will be quite difficult for you to ask for donations next time.

Therefore, the banquet was changed to a simple meal.Only the simplest meals are arranged, provided by the "cooking hall" in the university, meal coupons are issued, and everyone eats their own.

So much the better.

In fact, Song Ping really didn't want to spend money on food and drink.Although there is a lot of money donated by various parties, there are still many places to use the money to run the university.He is not willing to spend it on such a so-called place.It's just that the secular world is like this. He was worried that he would neglect the donor, so he followed the secular world.

Now that I have Su San's support, I also understand the joints, and I know that there is still a big difference between righteous learning and other things, so I follow Su San's suggestion and make arrangements together.

It was precisely because of these arrangements that Song Ping had no time to go to the East Lake, and Su San had a few more days of leisure.

But starting from the fifth day of the twelfth lunar month, it began to rain suddenly again on this day. Although the winter rain was not heavy and it didn't last long, the cold, windy and rainy weather did not make people happy.

After being bored in the room for two days, Li Yue'er and Mr. Li came to him in the rain when they were chatting.

Humans are actually strange. When they have something to do, they feel bored, and when they have nothing to do, they feel bored.But where in this world can we find something to do for a few days and rest for a few days?

"Old man, Yue'er, sit down. It's raining today, why did you come to my place?"

Mr. Li smiled: "Old man, I would like to come over to have a chat when the weather clears, but I can't help but my daughter can't keep things hidden in her heart. As soon as the case is confirmed, I wish I could come over at night."

Li Yue'er blushed, thinking, how could a father say that about his daughter.He looked up at Su San with a faint smile on his face, as if he didn't mean to laugh at her, so he felt relieved.

"So, the case has been finalized?" He was happy when he heard Mr. Li say that.

Mr. Li nodded: "Let Yue'er tell you. These are all handled by Yue'er. The old man is just helping out and helping."

He turned his gaze to Li Yue'er.

Every time Yue'er sees Su San now, her mood will easily fluctuate, especially when Su San touches her, or talks to her in a soft voice, her heart will beat wildly a few times.Therefore, every time you speak, you have to adjust your mood a little, so that your thoughts will be smooth.

After taking a few breaths, Yue'er said slowly: "Because the book Ning Yuan gave contains too much content, so we only picked one of them and tried it first."

"Oh, what's the choice?" It's what he meant by picking one and doing it first.What he cares about is which product to try first.

"Shampoo!" Li Yue'er got a little excited when she mentioned this.

He was surprised when he heard what Li Yueer said.He gave the formula for the shampoo, but he didn't think that shampoo could be made in this era.

To make a real shampoo, there are three aspects that need to be met.The first is to have an anionic surfactant with good decontamination effect, high safety and mild nature.

The second is an ingredient for soft hair care.This is difficult to achieve, because in the previous life, the shampoos made were all made of high-viscosity silicone ester, silicone oil and other chemicals.

The third is antistatic ingredients, such as guar gum, polyquaternary salts and other cationic polymers.

In addition, ingredients such as preservatives, essences, pearlescent agents, antipruritic and anti-dandruff agents are also needed.

The production of this shampoo was originally an experimental subject in his university.Because the shampoo he made by himself almost washed people's hair away, so he had carefully studied the correct formula of the shampoo, so he always remembered it deeply.Afraid of washing people's hair away, I have studied in detail whether it is possible to replace the raw materials of shampoo with pure natural materials to avoid the harm of chemical agents to the human body.

But I have to say that it is an impossible task to use pure natural materials to make real shampoo.Essence can be natural, and preservatives can be replaced by propolis, essential oils, etc.But pearlescent agent, guar gum, silicone oil, etc. can be replaced by natural things.

If you don't care about such a good effect, you can try it.

Therefore, when he wrote this formula, he thought more about recalling the previous life, and did not hold the hope that it could be made, so he wrote it in a very general way, but it was written symbolically: raw materials with strong decontamination ability, hair care Ingredients for softening hair, thickening natural substances, combined with propolis, spices, essential oils, acids, and anti-itch ingredients.

He never thought that such a simple recipe list would be chosen by Li Yueer.Because, in the whole book, he felt that it was the least possible thing to make.

But he couldn't say that this was the most unreliable. After being taken aback, he smiled and asked, "This is a bit difficult."

Li Yue'er smiled, pointed at her hair, and smiled at Su San.

He squinted his eyes, and saw that Li Yueer's shiny black hair was indeed different from the past.With a heartbeat, he hurriedly walked to Li Yueer's side and went.

Li Yueer's hair was only tied up casually with a piece of silk ribbon, and the hanging hair was draping softly on her back.Gently stroking with your hands, the hair is very dry.

It is almost impossible for women in this era to have dry and smooth hair.If you don't use oil, your hair will definitely look like crazy.

"Hey." Su San smelled a faint fragrance, couldn't help but groaned, and leaned over to sniff Yue'er's beautiful hair.It has a sweet taste.

"Is this scent the scent of honey?"

Li Yue'er was already blushing from Su San's actions, she nodded slightly, and at the same time looked at Su San with some complacency.

"Well, it seems to be better than the original. It is brighter and darker. It feels slippery in the hand, but it doesn't have the wet hand feeling of hair oil. So, you have not only made this shampoo Come out, and have you already used it?" When Su San said this, thinking of the experience of almost washing someone's hair off when she was in college, she couldn't help feeling a little scared.If Li Yue'er washed her hair off according to her formula, wouldn't that be a pain for herself?However, he also remembered that there are no chemicals in this era, and all raw materials should be safe and poisonous. Even if they use the wrong things, the mistakes of his previous life will not occur.

Li Yue'er nodded again, and said to Mr. Li, "Take it out and show Ning Yuan."
