Erin took Charlotte and Amelia through the compound full of rides and walked into the small courtyard arranged for the two.

The Ming-style manor has many large courtyards and small courtyards, which can allow the whole family to live together without interfering with each other.

In the living room of the main hall where Charlotte and Amelia lived, Erin asked both of them to sit down and let her maid put the basket on the table.

Then Irene commanded the two English maids:

"These are the toiletries commonly used in our palace, first give your Highness to see if you are allergic, and then change if you are allergic."

[In view of the general environment,

Charlotte and Amelia, as well as their maid, didn't know what the word allergy meant.

Amelia, in order not to make herself appear ignorant, did not ask, but instinctively thanked first:

"Thank you, Your Highness Irene, we came out in a hurry this time, and we didn't bring the toiletries we usually use.

"Now we are all very honored and very happy to be able to use the things of the Ming Court."

Charlotte also thanked her immediately, but the child didn't have so many ideas, and asked directly with some surprise and curiosity:

"Your Highness Irene, what do you mean by allergies?"

Erin explained it as plainly and plainly as possible:

"It's just something, when it touches your body, it makes your body itchy, red, and even pimple.

"When you first arrive in an unfamiliar place, it's best to try new cosmetics and toiletries."

Allergic reactions have been known for a long time, but there are no systematic studies, or even a unified name.

Charlotte immediately understood what was going on, and Amelia immediately said gratefully:

"Thank you, Your Royal Highness Irene, the preparations in the Daming Palace are really careful, we didn't expect these ......

Erin asked Charlotte's maid to take a small amount of the toiletries she had brought and apply it to the back of Charlotte and Amelia's hands:

"Here's shampoo, here's shower gel, here's soap......

"Well, it looks fine, these things are generally not allergenic.

"Finally, there's this antiperspirant lotion, which we rarely use ourselves, so we need to be a little careful......

Charlotte and Amelia turned out to be very cooperative, and when they heard the antiperspirant deodor, they immediately had a bit of a stress reaction.

Amelia subconsciously waved her hand and said:

"No...... We don't need this, we don't usually sweat......

In Zhu Jingyuan's chemical laboratory, a brand new product has recently been developed, which is a special attack on Xiyi.

Aluminum hydrochloride.

Look at the name is mediocre, and even make people forget it.

But this material is very useful, it is the most common antiperspirant active ingredient in later generations.

It is able to converge the apocrine glands and reduce the amount of sweat excreted, while fusing with sweat to form a bio-gel.

If the bacteria on the surface of the body cannot obtain the proteins secreted by the apocrine glands, they will not be able to produce the bacterial metabolites that produce body odor, and the corresponding odor will be curbed.

In the right amount, it can last for two to three days.

Even if you have a beard odor, as long as you take a bath every morning, use an antiperspirant with similar active ingredients, and do not engage in strenuous activities during the day, you will basically not be found to have a beard odor.

If you use it for a long time and for life, even if you are a couple living together, you may not be able to find out that the other party has a bad smell.

In Zhu Jingyuan's last life, antiperspirants were daily chemical products with the same status as toothpaste, shampoo, and shower gel in Europe and the United States.

Antiperspirants actually appeared very early, because after the Tessie people entered the civilized society, this product was "just needed".

Early antiperspirants were very confusing, with ammonium chloride, potassium dichromate, chlorinated lime and even yeast acting as antiperspirants.

Side effects are also obvious, usually more corrosive, or there will be color, contaminating clothing.

It was not until the beginning of the twentieth century that alumina, which was relatively effective and had fewer side effects, appeared.

Aluminium chloride is a subsequently screened alternative product that works on the same principle as alumina, but is less irritating.

Of course, aluminum hydrochloride is an active ingredient and cannot be sold directly as an antiperspirant product.

To make a solution, add bactericidal materials, and a relatively clear flavor, and sell it in the name of toiletries.

This kind of product is suitable for opening up sales from women, and women are more interested in it than men.

So Charlotte and her little aunt Amelia can be the earliest users and spokespersons of this type of product.

It's just that they who live in this era have a lot of thoughts about the early antiperspirants of this era.

They prefer to be less active and take a shower two or three times a day than to use those things.

At the same time, just like the unspeakable, the Tessie women of this era are also ashamed to talk about sweating and body odor.

Even if you want to use antiperspirants, you will use them secretly, and you will not talk about them openly at all.

So Amelia instinctively said she didn't need antiperspirants.

Erin had been prepared for this for a long time, and asked directly with a smile:

"Your Highness, don't shy away from medical treatment, sweating is a physical instinct, and it is not subject to human will.

"Can you be sure that you won't sweat when you're walking in the sun, when you're playing in the playground, when you're dancing at a party, when you're even ready to have fun?

"Of course, a polite and cultivated aristocratic man would not say to his face that a woman sweats a lot and has a heavy body odor.

"I've heard of a nobleman who, after dancing with his female companion, went to his room to have a private conversation when he was smoky by the smell under his female companion's lifted skirt.

"At that time, this aristocratic man would definitely not say anything directly to his female companion, but how do you think this kind of story came about?

"You don't really think that if those men don't say anything to their faces, they really don't care, do you?

"When the Tessie woman herself goes to the toilet, she probably dislikes her salted fish-like rancid smell, right?"

Amelia blushed slightly and stopped talking.

There's no way to argue with that, because it's true.

Charlotte's cheeks were also slightly red, and her expression was very tangled.

Body odor usually doesn't start until after puberty, and Charlotte's flavor hasn't been fully released.

But it's also starting to taste, and I'm always going to grow up.

So Charlotte was very worried and said:

"In other words, when I go to see His Royal Highness Prince Daishi, it's best to use antiperspirants......

"When I was playing in the courtyard, if I suddenly met His Royal Highness the Prince, would I smoke him away?

"But I've heard from the maids that antiperspirants are irritating and stain clothes.

"They all said it was better to be less active and take a shower in the morning and once in the afternoon......

Erin smiled and said:

"It's just that it might be exciting, so I'm going to let you test it first.

"Moreover, this is a new development of our Royal Highness the Prince, not the previous ones.

"We didn't have body odor, but after trying it on our bodies, we didn't feel uncomfortable."

When Charlotte and Amelia heard that this was Zhu Jingyuan's invention, they immediately became interested.

"It's the invention of His Royal Highness!"

"That should be fine......

Now Zhu Jingyuan's popularity is very high, and the things he invented are very magical.

Promoting it in the name of Zhu Jingyuan immediately had a completely different effect.

Charlotte and Amelia finally accept Erin's suggestion and decide to give it a try.

The two maids each picked up a bottle of deodorant and applied some on the back of Charlotte's and Amelia's hands.

The two English princesses looked at the back of their hands with curiosity and apprehension.

"It's cold, there's nothing uncomfortable......

"It looks like the skin is a little tight......

Erin explained on the side:

"It's a little tight, the antiperspirant will tighten the pores, and there will be less sweating......

"Whatever is applied to the skin slowly turns into a state like ice foam as the sweat increases.

"But don't worry, if you rinse it with water, it will dissolve and disappear without leaving any traces.

"As long as you don't have an allergic reaction, you can use it normally without worrying about damaging your clothes."

Charlotte looked curiously at the back of her hand, trying to experience the feeling of tightening her skin.

Amelia listened to Erin's explanation by the side, and was very pleasantly surprised:

"This works...... It's the perfect deodorant......

"This is bound to become popular in the circles of the Tessie nobility."

Erin smiled and nodded:

"The invention of our Royal Highness the Prince, of course, is perfect.

"It's definitely popular, and now you're the first to experience it."

As soon as Erin said this, Charlotte and Amelia immediately became happy

"yes, I used it first!"

"It's us, my dear aunt."

Both Charlotte and Amelia received the antiperspirant lotion.

Erin continued to chat with them and waited for twenty minutes to confirm that neither of them had an allergic reaction.

Then he said goodbye and left, took the car back to Ciqing Palace in the Forbidden City, and reported to Zhu Jingyuan's study:

"Your Highness, the two British princesses have settled down, and they are very interested in your amusement park.

"The antiperspirant was also sent to them, and they should be honest in the future, and it won't smoke you.

"The display of the clothes is also very good, and the woman of Tessie really prefers this style.

"Especially that little queen of America, her eyes lit up when she looked at me."

Zhu Jingyuan took Erin's hand, wrapped her around her waist, and let her sit on his lap:

"Thank you, you've been wearing this for a few hours, how do you feel? Does your foot hurt?"

Erin leaned on Zhu Jingyuan's arms very comfortably:

"The foot is not painful, after all, the heel is only three centimeters relative to the front, and the sole of the foot is relaxed when moving.

"It's just that the calves are a little tired, probably because the soles are thick, and they feel a little heavy when walking."

Zhu Jingyuan patted her buttocks:

"Then let's go and change our clothes and shoes."

Erin immediately shook her head:

"I don't want to change, I like this kind of clothes, I like this kind of shoes, I also like this kind of shoes......

Zhu Jingyuan smiled and rubbed the meat on her calf:

"Then rest for a while and don't run around......

Erin looked up at Zhu Jingyuan and said with a smile:

"I just want to rest here......
