Are surfactants harmful to humans? What are the specific aspects?

Rare. Washing powder.

and soap are both surfactants.

Generally, there is no big impact on food and daily use, because they have passed the national inspection of teratogenicity, carcinogenicity, pathogenicity and other indicators.

However, if it is an industrial chemical industry, because there is no requirement in this regard, it may not be good. However, when working in laboratory testing, the dose involved is very small, and the impact should not be large.

The most common and commonly used items containing surfactants are various detergents. In recent years, scientists.

It is found that detergents have a certain impact on human health, especially if pregnant women use them carelessly, which is not conducive to the development of the fetus.

Of course, it is harmful, the so-called surfactant is often called surfactant, its main function is to make fat-soluble substances water-soluble. This type of substance is mainly used in detergents such as soap, toilet liquid, etc.

I can tell you with certainty that it is false to say that it is not harmful to you, but it is generally volatile, basically no smell, there is no residue of ingredients, and there is no harm, what is the surfactant you are talking about, I don't know, I don't know the ingredients, and I don't know the harm.

Not in general. Laundry detergents and soaps are both surfactants. Harmful are now long since banned.

Facial activants can penetrate the human body. The detergent on the ** has about entered the bloodstream, and if there is a wound on the **, the penetration is increased by more than 10 times. Chemical toxins that enter the human body can cause the concentration of calcium ions in the blood to decrease, the blood to acidify, and people to get tired easily.

These toxins also reduce the liver's ability to detoxify. The toxins that should be excreted from the body accumulate in the body, which weakens people's immunity, aggravates hepatocellular lesions, and is easy to induce cancer.

When chemical detergents invade the human body and combine with other chemicals, their toxicity increases several times. In particular, it has strong carcinogenic properties. According to relevant reports, the artificial experiment of cultivating gastric cancer cells and the injection of LAS (anionic surfactant), a basic substance of chemical detergent, will accelerate the deterioration of cancer cells.

LAS is also very blood-soluble, which can easily cause changes in hemoglobin and cause anemia.

SurfactantsWhen dissolved in liquids (especially water), the content of the solution can be significantly reducedSurface tensionor interfacial tension, and can improve the solubilization of the solutionEmulsification, dispersion, penetration, wetting, foaming and washing.

Surfactants have a common characteristic, that is, the presence of both hydrophilic and lipophilic groups (also known as hydrophobic groups) in the molecule. Hydrophilic groups are usually groups that are easily ionized after being dissolved in water, such as carboxylates, sulfonates, sulfates, etc., as well as hydroxyl or polyoxyvinyl groups that are not ionized in water.

Lipophilic groups can attract and dissolve with oils, and are usually hydrocarbon groups with long carbon chains composed of petroleum or oils, which can be aliphatic hydrocarbons.

It can also be aromatic hydrocarbons.

If the hydrophilic base has strong performance, it will be soluble in water, and conversely, if the lipophilic base has strong performance, it will be soluble in oil.

Changing the interface properties between the two-phase substances can play the functions of wetting, penetration, cleaning, dispersion, emulsification, solubilization, foaming, defoaming, etc. Surfactants can be divided into anion and cation according to their structure.

Zwitterionic and nonionic surfactants.

Anionic surfactants can be dissociated into anions and cations in water, and anions play a role in reducing surface tension.

SurfactantsThe main ones are wetting andOsmosis, emulsification, dispersion, foaming. Surfactants have a wetting and penetrating effect due to their ability to significantly reduce the surface tension of water.

Two immiscible liquids, one of which is dispersed in droplets in the other, is called emulsification. Emulsification tends not to occur spontaneously or persistently.

Characteristics of surfactants

Surfactant refers to the addition of a small amount of substances that can significantly change the interfacial state of the solution system. Has a fixed hydrophilic and lipophilic group on the surface energy of the solution.

Directional arrangement. The molecular structure of surfactants is amphiphilic, with a hydrophilic group at one end and a hydrophobic group at the other.

Hydrophilic groups are often polar groups, such as carboxylic acids.

Sulfonic acid, sulfuric acid, amino or amine groups and their salts, hydroxyl groups, amide groups, ether bonds, etc. can also be used as polar hydrophilic groups, while hydrophobic groups are often non-polar hydrocarbon chains, such as 8 carbon atoms.

above the hydrocarbon chain. Surfactants are divided into ionic surfactants, non-ionic surfactants, amphoteric surfactants, compound surfactants, and other surfactants.

Surfactants have become a class of flexible, diverse and widely used fine chemical products due to a series of physical and chemical effects such as wetting or anti-sticking, emulsification or demulsification, foaming or defoaming, solubilization, dispersion, washing, anticorrosion, antistatic, etc., as well as corresponding practical applications. In addition to being used as a detergent in daily life, surfactants can be used in almost all fine chemical fields.
