I still remember my cardamom year, when my family was too busy to take care of three meals, they sent me to boarding school.
On the first day when she arrived in the dormitory, she was shocked by a roommate: she did not take a bath with soap, but with a bottle of emulsion.
[This, called shower gel, is very advanced! She introduced me seriously.
I nodded like garlic.
Many years later, shower gel has already entered thousands of households in the north and south of the great river. There is no mystery at all. But in the heart of an elderly person, it always seems that it is a little more advanced than soap. In other words, if a person who uses shower gel suddenly lets him use soap, his quality of life will feel as if his quality of life has slightly decreased. In fact, is shower gel a how existence?
Is shower gel better or soap better?
Soap detergents are the oldest and most common detergents, Around 2500 BC, On a Sumerian clay slab appeared Sumerian written in deformed characters. It first mentioned soap, There is also the washing of wool clothes. Pompeii, a city destroyed by the eruption of Mount Vesuvius in 79 A.D., A complete soap factory was discovered during the excavation of its ancient city. For thousands of years, soap/soap has made great contributions to improving our living hygiene. Data show that the higher the soap/soap consumption in a country, the lower the infant mortality rate.
The reason why soap cleaners can decontaminate, It is by mixing with water on the skin surface, Form soap salt, emulsify skin surface dirt to achieve the goal. Because soap salt is alkaline, so it has strong detergent, sebum is easy to remove, but also has certain irritation to skin. Some improved handmade soaps add glycerin, vitamin E and other moisturizing ingredients to reduce irritation, but after all, they cannot be compared with synthetic cleaners.
Synthetic cleanser is represented by compound shower gel, The main component is surfactant, and artificial synthetic cleaning agents such as moisturizing and bonding are added at the same time. The purpose of cleaning is achieved by emulsifying and wrapping the dirt on the skin surface, and the pH value on the skin surface can be maintained in the physiological range of 4.5-5.5 while cleaning. Compared with soap cleaning agents, the compound shower gel has obviously reduced irritation to the skin, but its detergency is not as good as soap.
It can be seen from this that soap and shower gel have their own advantages, and no one has a higher level. For people who sweat more in hot seasons, soap can wash their bodies clean, and for people who are dry and sensitive in autumn and winter, shower gel can reduce irritation and protect the normal barrier function of skin.
Ordinary Body Soap and High Price Body Soap
There are many shower lotions on the market like stars, which often bring different feelings to people. Many people have difficulty in choosing when facing supermarket containers.
In fact, these differences are mainly determined by the surfactant of shower gel. The surfactant of shower gel is mainly divided into soap-based type, surfactant dosage form and compound type.
1. Soap-based type
Soap-based shower gel is cheap in cost, large and rich in foam when rubbed, refreshing and not sticky when washed, but it is actually liquid soap, and its irritation to skin is not low. In order to maintain the stability of the product, the general pH value must be greater than 9, i.e. Some free alkali exists in shower gel, which is the main reason for dry and tight skin.
2. Surface active dosage form and compound form
Surfactant forms and composite shower gel are new things that have gradually arisen in recent years, with higher cost than soap-based shower gel. Among them, amino acid anionic surfactants can bring dense foam and considerable detergency. Coconut oil zwitterionic surfactant has mild properties and little damage to normal sebum layer. Some infant shampoo and bath two-in-one products use non-ionic surfactants that are not irritating to eyes.
These shower lotions with special functions are expensive. People need to know what is inside before they can make more rational consumption choices according to their own needs.
For ordinary people, they sweat a lot in summer, so they can choose soap-based detergent. In autumn and winter, the climate is dry, and the use of compound detergent is less likely to cause chapped skin. If your skin is very dry, you can only wash clear water.
Shower gel should not be commonly used by the following people
1. Older persons
As one grows older, Our skin will also undergo a series of physiological aging phenomena, The most obvious point is the sebaceous gland secretion decline. The elderly because of sebaceous gland body function decline, skin atrophy, dry itching, if at this time again use hot water, detergent to excessively clean the skin, it is more likely to aggravate the skin dry itching, desquamation, causing the elderly pruritus. Therefore, daily bathing with water similar to body temperature can be.
2. Infants
The sebaceous glands of infants under one year old are not yet fully developed. Use clear water for daily bathing. If the weather is hot and sweats more, then use some infant-specific low-stimulation bath lotion as appropriate, but it is not necessary to pursue absolute cleanliness. In particular, the fetal fat on the skin surface of the newborn has a protective effect on its skin. This layer of fetal fat will fall off before and after the full moon, and parents need not rush to wash it off.
3. Patients with eczema, atopic dermatitis and rosacea (rosacea)
Eczema and atopic dermatitis are chronic skin allergic diseases, Rose acne is commonly known as rosacea. The epidermal barrier function of patients with these types of skin diseases is damaged. Daily care needs to reduce stimulation. Even synthetic cleansers such as shower gel and facial cleanser do not need to be used every day, let alone soap cleansers. And after each skin cleaning, moisturizing products should be applied to moisturize the skin as soon as possible to reduce the sensitivity of the skin.
