When Su Jinli heard Chu Xuan's words, she only felt speechless for a while.

After being silent for a while, he said with a smile: "Why don't you try this toothpaste first, third brother, and then we will talk." ”

Chu Xuan thought about it and decisively agreed.

The housekeeper personally led him to the bathroom next to him to try on toothpaste.

After a while, Chu Xuan walked out excitedly, with a smile on his face: "Sister-in-law, your toothpaste is so easy to use!" ”

Unlike the tooth powder he used before, his mouth was full of scum, not to mention, it was cold and silky, which was very comfortable.

After using it, the cool taste of mint still remains in my mouth, which is much more comfortable than before.

Su Jinli saw that he was happy, so he asked him: "Third brother, what do you think is the right price of this toothpaste?" ”

"Well...... this" Chu Xuan touched his chin and began to seriously ponder the appropriate price, "If you use this kind of glass jar to hold it, such a jar of toothpaste will cost at least a hundred taels of silver to be suitable." ”

He had just finished the treasure appraisal meeting, and the glazed ware at the treasure appraisal meeting was sold at a high price.

Even if the price of the glazeware that is usually sold is lowered, it can't be too cheap.

Chu Xuan thought of this, and asked worriedly: "By the way, sister-in-law, I don't know how much this toothpaste costs?" Can it be too high? ”

"The cost of toothpaste-" Su Jinli deliberately lengthened her tone, "Such a jar is probably only a hundred yuan, if you can expand production in the future and reduce the cost of raw materials, the price can be lower." ”

In fact, the cost of 100 yuan is still because of the problem of raw materials.

The toothpaste formula is not troublesome, it is mainly composed of friction agents, foaming agents, humectants, thickeners, sweeteners, preservatives, corrosion inhibitors, active additives, flavors, pigments, water, etc.

If you add some drug formulas to it, the toothpaste can also have certain therapeutic effects.

For example, anti-inflammatory and hemostatic or something.

Among these ingredients in toothpaste, the amount of friction agent is the largest, accounting for one-fifth or even half according to different formulas, and calcium carbonate can be used as a friction agent.

How expensive can this thing be?

The foaming agent is more troublesome, but its function is to increase the foaming and decontamination ability, even if there is not, the toothpaste can be made, but the effect is definitely worse than the modern variety of toothpaste.

Moisturizers are simple, just use glycerin.

The thickener can use sodium alginate, which is extracted from seaweed, and with the current technology, it can also be done, as long as there is enough seaweed.

It's easier with sweeteners, just add a little sucrose.

Preservatives can be obtained by sodium benzoate, dry distillation with benzoin gum, alkaline hydrolysis, or hippuric acid hydrolysis.

The effect of the corrosion inhibitor is to delay the toothpaste corrosion of the toothpaste tube, and she uses ceramic jars or glass jars to hold the toothpaste, so naturally there is no need to add this thing.

There are many active additives, such as fluoride, Chinese herbal medicine, amino acids, whitening agents, desensitizers, vitamins, peptides, biological enzymes and so on.

With the current conditions, other things are not easy to get, but Chinese herbal medicine is completely fine, there are many things.

The rest of the flavors, pigments and water, it is easier.

The toothpaste she showed Chu Xuan was a little peppermint essential oil. However, the cost of refining essential oils is relatively large, so it increases a lot of costs.

If you have pigment, you can add it or not, it is mainly used for color mixing, and it has no effect.

So all the things are calculated, and the cost is really not expensive.

It is not even as good as the tooth powder used by many rich and noble people now, with a lot of precious spices added to it, and the price is not cheap.

After Chu Xuan heard Su Jinli say the cost, the whole person was stupid. He opened his mouth wide and looked at Su Jinli in disbelief: "Sister-in-law, are you serious?" The cost of this thing is so cheap? "Love Net

Su Jinli rolled her eyes speechlessly: "What good is it for me to lie to you about this?" ”

Chu Xuan: "......"

That's right, this cost is a big problem, and my sister-in-law has no reason to lie to him!

However, the cost of this toothpaste is too low!

Chu Xuan felt his heart beating fast.

The butler who was guarding on the side also felt his heart pounding.

The cost is only 100 yuan, and if you sell it for 100 taels of silver, how much profit will be here?

The butler suddenly felt that his brain was a little insufficient.

At this time, Su Jinli said again: "Don't you already know how the glass is burned?" How much does it cost to burn glass? ”

Chu Xuan's face changed instantly, and he felt a sense of empowerment.

He realized that he was really confused.

My sister-in-law is right, the cost of glass is so low, but it hasn't been sold for a sky-high price?

The cost of this toothpaste is a little lower, so what does it matter?

It doesn't stop them from selling at a high price!

Thinking of the low cost of toothpaste, he didn't resist selling it to barbarians.

The cost of toothpaste is so low, you can just take it to the pit for those ignorant barbarians!

Su Jinli saw that he looked eager to try, so he said again: "The cost I just said is just the cost of ordinary toothpaste, in fact, some drug formulas can be added to toothpaste, so that toothpaste can get some curative effects." In this way, the cost can go up. ”

Chu Xuan smiled when he heard this, rubbed his hands excitedly and said, "This is good, this is good!" When the time comes, add some ginseng and deer antler velvet in it, and you are not afraid that you will not be able to sell it at a high price! ”

Su Jinli shook his head with a smile, and didn't interrupt him, letting him play as he pleased.

So Chu Xuan was excited there alone for a while, only to realize that he seemed to be a little embarrassed like this.

He asked Su Jinli again: "What about this shampoo and perfume?" ”

Su Jinli said lightly: "The cost of shampoo is not high, but a lot of spices are used in the perfume, and the cost is not low." ”

Chu Xuan understood as soon as he heard it.

Since the cost of this shampoo is not high, you can sell it however you want. Perfume, as soon as you hear it, is a luxury, and since the cost is not low, it must be sold at a high price.

Looking at the appearance of this perfume, it is obvious that it is not cheap.

The ladies of wealthy families must be willing to pay a lot of money to buy it.

If the scent is fresher, maybe even some men will like it.

The more Chu Xuan thought about it, the more excited he became, and he almost couldn't wait to ask: "Sister-in-law, are you planning to build a factory to do business when you take these out?" ”

Su Jinli raised the corners of her lips with a smile: "Otherwise? In addition to these, there are also soaps, snow creams and lipsticks from last time, which are all good deals to make money, don't you think? ”

"Of course I do!" Chu Xuan said with great certainty, "Sister-in-law, don't worry, junior brother, I will enter the palace to ask for my father, and I will definitely form a merchant group!" ”

Such a profitable business, of course, you have to pinch it in your own hands!

Chu Xuan hurriedly said goodbye to Su Jinli and couldn't wait to enter the palace.
