This war in the daily chemical industry, no matter what the original cause was, but it dragged on for two months, and such a long battle is no longer something that ordinary enterprises can bear.

Not to mention small and medium-sized enterprises, even Procter & Gamble and Unilever are miserable.

Just like Yang Fei said, after entering this battle circle, no one can jump out, so he can only fight until he is defeated to death.

Yang Fei decided to use a new product launch conference to end this bitter battle in which no one could get benefits.

April 1, 96, this day, in the eyes of Westerners, is April Fool's Day.

But for the Chinese people, the advent of this day is the beginning of the Qingming Festival activities.

It rained a lot before and after Qingming, and the first three days and the last three days were all days of sacrifice at the grave.

The willow tree on the side of the road pulled out the young shoots, and the green makeup became a tree high, and a branch was broken off, and a ring was braided and worn on the head, which had a special flavor.

On Yang Fei's head, he was wearing such a wicker ring, and some small wildflowers were inserted on it.

This was compiled for him by Su Tong, saying that wearing it on his head would bring him good luck.

Today's Yang Fei really needs a little good luck to support.

The new product launch conference of white laundry detergent was held in the lobby on the first floor of the beautiful building in Beijin Wudaokou.

A huge screen hangs in front of the stage, and a promotional film of the history of laundry detergent is repeatedly played on the screen.

"Chang'an is a month, and thousands of households pound clothes. The autumn wind blows endlessly, and it is always a jade relationship. ”

This poem depicts the laundry activities of the working people in ancient China.

In ancient China, the working people used the clothes pounding pestle for laundry, also known as the clothes pounding anvil, wooden, similar in shape to a baseball bat, about 30 centimeters long, relying on the power of the clothes pounding pestle to beat the clothes, and bringing out the dirt with water.

Therefore, washing clothes in ancient China was called "pounding clothes".

It is said that the laundry pestle was invented by people who lived near the water for the convenience of laundry, and the washboard was invented by people who lived far from the water.

Well, the washboard has come to life and is said to have a completely new purpose?—— which cannot be described here.

The most beautiful description of laundry is "Shih Tzu Huansha".

When the beautiful Xi Shi was in the river, the fish saw her reflection and forgot to swim to the bottom of the river, so Xi Shi has the pronoun of "sinking fish" and has become one of the four beauties in the history of our country.

Laundry is one of the most basic household chores and used to be the most physically demanding.

After 4,000 years of experimentation, humans have finally found an easy way to do laundry. Hailed as one of the 100 greatest inventions in history, the washing machine not only represents the wisdom of the modern industrial revolution, but also frees millions of people from heavy housework.

The original laundry cleaning material is that people stumble upon utensils stained with some substances during rituals or barbecue activities, and then find out the reason and discover the mystery of cleaning clothes.

This miraculous substance is plant ash.

It is recorded that in 600 B.C., when the Phoenicians mixed goat fat with plant ash to make soap, the Phoenicians discovered the superior properties of surfactants, which weakened the surface tension of water, allowing water to penetrate the fabric better, breaking down dirt and allowing it to float to the surface until it was finally washed away.

The ancient working people of our country also discovered that plant ash can be used as a detergent.

The Book of Rites and the Inner Rules says: "The crown is dirty, and the ashes are clean." It means that when the strap of the hat is dirty, it is washed with the ashes of the plants and trees.

This is because the potassium carbonate in plant ash removes oil.

According to the record of "Examination of Work", the ancients in order to make the silk soft and white, the silk silk was wet with grass and wood ash water, and then put in the ash made of shell burning, the ancients called it "mirage", and soaked it in water.

This is because plant ash water and shell ash can react to produce a strong alkali – potassium hydroxide.

Generally, the dirty substances on clothes are mainly oils, and most of the oils belong to oils, and under alkaline conditions, the degree of hydrolysis is intensified, and higher fatty acid salts and glycerol that are easily soluble in water are generated.

The main component of plant ash is strong alkali and weak salt, and its aqueous solution is alkaline due to the hydrolysis of carbonate ions.

During this period, in addition to plant ash, people also used a mixture of animal oil, vegetable oil, soaphorn, and alkali salts to clean clothes.

In the Han Dynasty, people already knew to use natural stone alkali to wash clothes.

During the Jin Dynasty, people added starch and spices to the stone alkali to make ingots for sale.

At the end of the Ming Dynasty, Beijing had a shop specializing in the sale of artificial soda, among which "Hexianglou" and "Huahanchong" were still selling boxed peach-shaped and gourd-shaped rose soda until the forties and fifties of the last century.

What about the "pancreas" that the older generation said?

During the Northern and Southern Dynasties, Jia Siqian had already mentioned the use of pig pancreas to remove scale.

There is a recipe in the "Thousand Golden Prescriptions" of Sun Simiao, the "medicine saint" of the Tang Dynasty: use washed pig pancreas, grind them into powder, and add soybean flour spices to make granules.

This is the ancient pancreas, also called bath beans.

Later, people combined pancreas and aroma alkali to make a large dumpling, such as osmanthus pancreas and rose pancreas.

With surfactants such as water and plant ash, people's clothes are much cleaner.

But whether it's with a laundry pestle or with your hands, it's hard to do laundry.

Is there a labor-saving way to do laundry?

Yes.

During the voyage to the sea, the sailors washed their clothes with minimal effort, stuffing their dirty laundry into a cloth bag, tying one end of the rope to the ship, and throwing the cloth bag into the sea, and letting the sea stir and beat the clothes during the voyage, and the clothes were washed.

Inspired by the "laundry of the sea", in 1677 someone invented a washing device that squeezed the flow of water through a device composed of wheels and cylinders, mimicking the effect of washing clothes on the sea.

This device is the prototype of modern laundry machinery.

The washing machine, hailed as one of the 100 greatest inventions in history.

Its greatness is not only the wisdom of the modern industrial revolution, but also the liberation of thousands of people from heavy housework and the indispensable necessities of life.

The promotional video stops abruptly here and continues to be repeated.

At the scene, in order to express the effect more intuitively, Yang Fei ordered people to place several washing machines and conduct a laundry demonstration on the spot.

Laundry, the most mundane thing in life. Laundry detergent has always been the main part of the laundry washing products.

However, careful people will find that laundry detergent does not completely dissolve during use, and the residue can easily cause damage to the clothes, and it is not easy to rinse.

The main ingredient of laundry detergent is non-ionic surfactant, which has strong decontamination ability, and can penetrate deep into the fabric fiber to exert a washing effect, and the decontamination is more thorough.

Moreover, no matter how high the quality of the laundry detergent is, it will hurt your hands to a greater or lesser extent.

This is because the traditional laundry detergent and soap use anionic surfactants, which are mainly sodium alkyl sulfonate and sodium stearate, which are more alkaline, and the pH of laundry detergent is generally greater than 12, which will irritate and damage the skin when used.

What the beauty group has launched this time is a brand new product that is completely different from traditional laundry detergent - laundry detergent!

Laundry detergent mostly uses non-ionic surfactants, with a pH close to neutral, gentle on the skin, and degraded faster than laundry detergent after being discharged into nature. It dissolves completely and quickly, is easy to rinse and wash, and does not hurt skin and clothing.

With the slogan put out by Yang Fei, he said: "This is a brand new detergent, the greatest new invention in the history of laundry, and the laundry revolution of the whole world will be refreshed from today!"

Countless media and reporters in the audience witnessed the birth of this miracle.

Can this new product end the industry war, and can Yang Fei and Meili Daily Chemical reach a new level?

Yang Fei has high hopes for this, and everyone will wait and see!
