Chapter 894

894, glycerol

it is false to say that it is not moved. At this time, the waves of Yanxin lake are rippling.

Let's not say whether the princess's business will be successful, but only that if the business hangs her name, the business belongs to her. When she takes all the money away, Princess Qianxue has nothing to do.

Not to mention the brother, it is the father and son in business is also clearly divided, let alone she and the princess Qianxue are not related.

If we say, in the past, her heart was only loyal to the master, but now, a heart is divided into two parts, and the other half is here in QianXue princess.

The former is because of saving lives, while the latter is due to sincerity.

"Don't worry, princess. I'll never do anything I'm sorry for." The voice of the first smoke is slow, his eyes are staring at Gu Qianxue, every word seems to swear.

Qian Xue chuckled, "OK, thank you very much."

Chu Yan is still excited.

Gu Qianxue has already changed the topic, "the words of cosmetics For the time being, I'm afraid I don't have time to research and develop. I put the cosmetics first and then use the skin care products I developed before. Toner, emulsion, cream, mask. "

Gu Qianxue, who had already changed his clothes and went to bed, took out his pen and paper, spread it on the table and began to write.

The cosmetics of this era are mainly divided into three categories: makeup powder, Dai powder and rouge.

There are two kinds of make-up powder, one is rice flour grinding, the price is slightly lower; the other is using lead powder, the price is expensive, two kinds of makeup powder are used to apply the face, make the skin appear white and smooth, similar to the modern powder.

Dai powder and rouge are needless to say, one is used for thrush, the other is lipstick.

The reason why Luoyan toilet box is so expensive is not only because of its mysterious formula, but also because of the refinement of skin care steps. Modern skin care products have the same characteristics.

For this era, the mysterious and magical Luoyan toilet box is so common in modern times that it can't be seen any more. Let alone some luxury skin care products with special effects, only the formal skin care products produced by the regular brand skin care products factory are more effective than the Luoyan toilet box.

Although some skittish skincare products were given to Qin Fei and others before, to be honest, that's the case. Most of them used essential oil and alcohol, and there was no scientific content at all.

Now, if it comes back really, we must take out modern things to shock the people in this time and space.

The first is glycerin!

Glycerin is very common in modern times. It can be bought in cosmetics stores or drugstores.

Glycerin, also known as glycerol, is a colorless, sweet, clear and viscous liquid. Because it can absorb moisture in the air and achieve the effect of moisturizing, it is widely used in skin care products.

, whether it is only a few yuan, the most inexpensive lotion or thousands of famous brand face cream, what can be less, glycerin can not be less!

In modern times, glycerin was first discovered by Schell in 1779. In 1823, people realized that the oil contained chevrol, which means sweet in Greek, so it was named glycerin. During the first World War, its production increased greatly because it was the raw material for making gunpowder.

Besides its function in skin care products, it can also be used as solvent, lubricant, medicament and sweetener.

When the word "glycerin" appeared on the paper, Gu Qianxue's cheek was full of relief.

Chu Yan couldn't help asking, "princess, what is this glycerin?"

Qianxue raised his eyes, "is a kind of thing that can slow down aging and keep youth forever."

Chuiyan was shocked.

Qian Xue chuckled and said, "I'm kidding. I just exaggerate. There is nothing in the world that can keep youth forever, but it is true to try to keep skin moist and delay skin aging. "

"Even if it is delayed, the effect is very good, but where can this glycerin get?" Chu Yan asked.

"By some means," said Gu Qianxue, writing another two words on the paper, "saponification.".

"Saponification?" These words have never been seen before by Chu Yan. She boasts that she has been following the master for many years, and her knowledge is much wider than that of ordinary people. However, she is extremely ignorant around the princess Qianxue.

Gu Qianxue explained that "saponification reaction usually refers to the reaction of alkali and ester, and the production of alcohol and carboxylate, especially the reaction of oil and alkali. In a narrow sense, saponification is limited to the reaction of oil mixed with sodium hydroxide or potassium hydroxide to obtain sodium or potassium salt of higher fatty acid and glycerol. If you listen to me so much, it must be like listening to the book of heaven? "

The first smoke nodded, "yes, I don't understand at all."

Qian Xue nodded, "it doesn't matter if you don't understand. Do you remember the salicylic acid extraction experiment we did before? This reaction is similar to salicylic acid extraction. You can understand it by hand. "

Chu Yan thought of the scene at that time, nervous, "is this thing also harmful to people?"

Qian Xue chuckled, "don't worry, there's no one." The first smoke has a good memory, salicylic acid extraction is indeed corrosive to the skin and cornea.

Chu Yan then put down his mind, "princess, you don't have to explain to the maidservant. It's an explanation. The maid doesn't understand. When she takes it, she will listen to the princess.""Thank you." Snow trail.

then wrote on the side and murmured, "saponification reaction can get two substances, one is soap, adding petals and petals dry powder can be made into wash, bathing or washing soap at ordinary times, and glycerol is of great use. After dilution, whether it is cream, milk liquid or mask, it is necessary to use the secret of saponification reaction. There is no possibility of counterfeiting. "

"Don't worry, princess. If someone comes to steal information, the maid will kill him." The first smoke shrieked.

Qian Xue sighed, "in fact, you don't have to be so tight. If I wasn't in a hurry to spend money, but I was willing to teach the recipe, the problem is Teach the apprentice to starve to death, and I have to earn money to raise the children in the nursery. "

But Chu Yan said, "the princess's formula, why send it free of charge? It's personal property! "

"Because..." Because of plagiarism. Later, Gu Qianxue didn't mean to say it. She always thought that the modern knowledge plagiarized should be specially used. It's really shameless.

But think, the world is so cruel - I for everyone, everyone may not for me.

If she is not a passing girl, but a native of Nanyue, she will be hard to die if she wants to raise such a group of children.

In this way, a great heart of the Virgin mother lowered her high head in front of the cruel reality. Gu Qianxue thought that she must keep the formula anyway, at least before she has enough money.

After the formula and product type are determined, the next problems are production and experiment, packaging design, processing factory and sales gimmick.

For production and experiment, Gu Qianxue decided to borrow the laboratory located in yushengju, Prince Li's residence. After all, its materials are complete; the design of the outer packaging is simple, so she continues her old way of plagiarism; the processing factory is ready to be located in xinmingju, which is originally a factory, and its plant design is more reasonable than ordinary residential buildings.

As for sales gimmicks Qian Xue squinted.

This must be well planned, what price skin care products can sell depends on whether the first shot can be launched!
