It is false to say not to be moved. At this time, Yanxin Lake was rippling.
Not to mention the success of the County Lord’s business, only that if the business hangs her name, the business belongs to her. After she has swept away all the money, Qianxue County Lord is helpless.
Not to mention brothers and sisters, it is because the father and son are clearly divided in business, not to mention that she and the master of Qianxue County are not close relatives.
If we say that in the past, her heart was only effectively loyal to her master, but now, one heart is divided into two, and the other half is here in Qianxue County.
The former is due to life-saving grace, while the latter is treated with sincerity.
"You can rest assured, the lord, the slave-maid will never do anything sorry to you." Chu Yan's voice was slow, and his eyes stared at Gu Qianxue, seeming to swear word by word.
Qian Xue chuckled, "Okay, thanks for the first smoke."
Chu Yan was still excited and impatient.
Gu Qianxue has turned the topic, "If you are looking for makeup... I'm afraid I don't have time to research and develop for the time being. I put on the cosmetic products first and then use the skin care products I developed before. Toner, lotion, cream, mask."
Gu Qianxue, who had changed clothes to bed, got out of bed again, took out a pen and paper, spread the paper on the table, and began to write.
The makeup products of this era are mainly divided into three categories: makeup powder, daifen and rouge.
There are two types of makeup powder, one is milled rice flour, which is slightly cheaper; the other is lead powder, which is expensive. Two kinds of makeup powder are used to apply to the face, making the skin look fair and smooth, and it has the effect of modern loose powder almost.
Needless to say, daifen and rouge, one is for eyebrow drawing, and the other is lipstick.
The reason why Luo Yanshen is so expensive is not only because of its mysterious formula, but also because it refines the skin care steps, and modern skin care products have the same effect.
For the era, the mysterious and mysterious Luo Yanshen is simply not common in modern times. Let’s not talk about some luxury skin care products with special effects, only the format skin care products produced by regular brand skin care products factories. It is more effective than Luo Yan Shuang.
Although I have made some small and troublesome skin care products to give to Qin Fei and others, to be honest, that's the case. At most, oil and alcohol are used, and there is no scientific and technological content at all.
Now, when this comes back, it is necessary to take out modern things to shock this person in time and space.
The first is glycerin!
Glycerin is very common in modern times and can be bought in cosmetics stores or pharmacies.
Glycerin, also known as glycerin, is a colorless, sweet, clear and viscous liquid. Because it can absorb moisture in the air and achieve a moisturizing effect, it is widely used in skin care products.
Whether it is a cheap lotion with only a few dollars or a brand-name cream with thousands of dollars, there can be less, glycerin can not be less!
In modern times, glycerin was first discovered by Scheier in 1779. In 1823, people realized that Chevreul was contained in oil and fat ingredients. Greek means sweet, so it was named glycerin.During the First World War, because it was the raw material for the manufacture of gunpowder, its output increased significantly.
In addition to its role in skin care products, it can also be used as a solvent, lubricant, medicament and sweetener.
When the word "glycerin" appeared on the paper, Gu Qianxue's cheeks were full of relief.
Chu Yan couldn't help but ask, "Master, what is this glycerin?"
Qian Xue raised his eyes, "It is a thing that can slow down aging and keep youth forever."
The first smoke was taken aback.
Qian Xue chuckled, "Just kidding, I just said it too exaggerated. There is nothing in this world that can keep you young forever, but it is true to try to keep your skin hydrated and delay skin aging."
"Even if it is delayed, the effect is very good, but where can this glycerin be obtained?" Chu Yan asked.
"Through some means," said Gu Qianxue, writing two other words on the paper, "saponification."
"Saponification?" These words are unprecedented for Chu Yan. She prides herself on following her master for many years, and her knowledge is much wider than that of ordinary people, but she is very ignorant beside the master of Qianxue County.
Gu Qianxue explained, "The saponification reaction usually refers to the reaction between alkali and ester, and the production of alcohol and carboxylate, especially the reaction between oil and alkali. In a narrow sense, the saponification reaction is limited to oil and sodium hydroxide or potassium hydroxide. Mix to get the reaction of the sodium or potassium salt of higher fatty acids and glycerin. You hear me say so much, it must be like listening to the heavenly books?"
Chu Yan nodded, "Yes, the slave-maid doesn't understand."
Qianxue 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 will understand it by hands-on operation."
Chu Yan felt nervous at the time, thinking, "Is this thing harmful to people?"
Qian Xue chuckled, "Relax, no." With emotion in my heart, the first smoke is very memorable. Salicylic acid extraction does have a risk of corroding the skin and cornea.
Chu Yan was relieved, "The master does not have to explain to the slave-servant, but the explanation is that the slave-servant also does not understand it. When the extraction is done, the slave-servant will listen to the commander."
"Thank you." Qian Xue said.
Then, muttered while writing, "After saponification, you can get two kinds of substances, one is soapy. Add petals and dry powder of petals to make soap for washing your face, bathing or washing your hands, and glycerin is very useful and diluted. Whether it is a cream, lotion or mask, it is necessary to use it, and as long as the secret of the saponification reaction is well protected, other businesses have no possibility of counterfeiting."
"The lord is assured that if someone comes to steal information, the slave-servant will kill him." Chu Yan said sharply.
Qian Xue sighed, "In fact, I don't have to be so tight. If it's not that I'm in a hurry to use the money, I'm willing to teach the formula. The problem is... The church apprentices starve to death, and I have to make money to raise the children in the nursery school. "
Chu Yan said, "Why should the master's recipe be sent out for free? This is considered private property!"
"Because..." because of plagiarism.Later, Gu Qianxue didn't mean to say it. She always thought that the plagiarized modern knowledge was used as a patent, which was really shameless.
But think about it, the world is so cruel-I am everyone, and everyone may not be me.
If she is not a transit woman but a native Nanyue country girl, she has to raise a group of children, for fear of death.
A great Madonna's heart just lowered her high head in the face of cruel reality. Gu Qianxue thought about it. She must keep the formula anyway, at least before she has enough money.
Formulas and product types are determined, and the next problems are production and experimentation, outer packaging design, processing factories and sales gimmicks.
For production and experimentation, Gu Qianxue decided to borrow a laboratory located in Yushengju, Li Wangfu. After all, the materials are complete; the outer packaging design is also simple, continuing her old plagiarism; the processing factory is preparing for the new nameless residence, which was originally a factory, according to The design of its factory building is more reasonable than that of ordinary residential houses.
As for the sales gimmick... Qian Xue narrowed her eyes.
This must be carefully planned, at what price skin care products can be sold, depends on whether this first shot can start!
