Frequently Asked Questions

What are the hazards of perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid) to human health?

Perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid) is harmful to human health.
It may cause damage to immune function. The human immune system, our company defends against foreign enemies and maintains the stability of the internal environment. However, when perfluorooctane sulfonic acid enters the body, it can disrupt the function of immune cells, reduce the body's ability to resist diseases, and increase the risk of contracting diseases. In case of exogenous evil, it is more susceptible to disease than ordinary people, and the recovery after the disease is also slow.
The harm of reproductive development is also even greater. In women, it can disrupt endocrine, cause menstrual disorders, difficult conception, and contact during pregnancy, or endanger fetal development, making the fetus teratogenic and growth retardation risk. In men, it can damage reproductive cells, reduce sperm count, reduce vitality, and affect fertility.
Furthermore, it is associated with the risk of cancer. Although it has not been confirmed as the culprit of carcinogenesis, many studies have shown that long-term exposure to PFOS-containing conditions increases the risk of developing cancer such as kidney cancer and bladder cancer.
The nervous system is also affected by it. Children are particularly susceptible, which can lead to cognitive development retardation, weak learning and memory, and difficulty concentrating, which is detrimental to future studies and life.
PFOS is difficult to degrade in the environment, easily aggregates in organisms, enriches through the food chain, and eventually enters the human body. It is harmful to health and cannot be ignored.

What are the main sources of perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid) in the environment?

The main sources of perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid) in the environment are two: man-made sources and natural sources, and man-made sources are the main sources of perfluorooctane sulfonic acid in the environment. In the past, perfluorooctane sulfonic acid and its salts were widely used in many industrial and consumer products due to their excellent surface activity, chemical stability and thermal stability. Such as surfactants, which are widely used in textile, leather, paper and other industrial production, giving products waterproof, oil-proof and anti-fouling properties; in the field of fire protection, foam fire extinguishing agents containing perfluorooctane sulfonic acid are often used to extinguish oil fires because they can quickly spread and form a stable foam layer to isolate oxygen. However, during the production, use and disposal of such products, PFOS is easily released into the environment and dispersed through air, water and soil.
In addition to natural sources, although the contribution of natural sources to PFOS in the environment is relatively small, it cannot be ignored. Some studies have shown that PFOS can be detected in marine organisms, and it is speculated that it may be caused by the metabolic process or natural chemical reaction of some microorganisms in the ocean to generate small amounts of PFOS. However, compared with anthropogenic emissions, the amount of PFOS produced by natural sources is very small.

What are the common application fields of perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid)?

Perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid) is an organic compound. In the past, it was commonly used in many fields.
First, in the field of surfactants, perfluorooctane sulfonic acid is often used in fabrics, leather and other waterproof, oil-proof and anti-fouling treatments because of its excellent surface activity. In the past, craftsmen made clothes with agents containing this substance, which could make fabrics water-repellent and oil-repellent, and durable for a long time, keeping clothes clean and beautiful.
Second, it is also used in the electronics industry. It can help improve the wettability and dispersion of certain materials during the manufacturing process of electronic components, so that the performance of components is better. When making circuit boards, the electroless plating solution can be distributed more evenly and the quality of the circuit can be improved.
Third, in the field of fire protection, perfluorooctane sulfonate was once a key component of water film-forming foam fire extinguishing agents. In case of fire, such fire extinguishing agents can quickly spread on the surface of fuel oil to form a layer of isolation film, effectively extinguishing fire, and protecting the safety of people's lives and property.
However, with the passage of time, the world gradually realizes the harm of this substance. It is persistent, bioaccumulative and toxic, difficult to degrade in the environment, and can be enriched through the food chain, endangering biological and human health. At present, many countries and regions have strictly restricted its use, looking for alternatives to ensure the peace of the environment and life.

What are the alternatives to perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid)?

Perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid) is harmful to the environment and organisms due to its persistence, bioaccumulation and toxicity, so it is necessary to find a substitute. Today, I will describe its common alternatives.
The first is perfluorohexane sulfonic acid (PFHxS). This substitute is structurally similar to PFOS, but its carbon chain is shorter. Studies have shown that PFHxS is slightly less bioaccumulative and persistent than PFOS. In some application scenarios, such as some surfactants, PFHxS can be used as a substitute. However, it should be noted that PFHxS also has certain durability and potential toxicity, and the long-term effects still need to be further explored.
In addition, there are short URL perfluorocarboxylic acids (PFCAs), such as perfluorobutyric acid (PFBA) and perfluorovaleric acid (PFPeA). These alternatives have short carbon chains and are better degradable in the environment than PFOS. In specific industrial processes and consumer products, such as textiles, leather treatment, etc., short URL perfluorocarboxylic acids can be tried as PFOS substitutes. However, its environmental behavior and potential impact need to be further evaluated.
There are also non-fluorosurfactants, such as betaine-type, sulfonbetaine-type amphoteric surfactants, and alkyl polyglycosides. These non-fluorosurfactants are biodegradable and environmentally friendly. In many traditional applications of perfluorooctane sulfonic acid, such as cleaning, coatings and other industries, non-fluorosurfactants can effectively replace perfluorooctane sulfonic acid through rational design and modification, providing similar surface activity and function.
There are other silicon-containing surfactants. It uses siloxane as the skeleton and has unique surface properties. In some occasions where surface tension, water and oil resistance are required, silicon-containing surfactants can be used as alternatives to perfluorooctane sulfonic acid, and some silicon-containing surfactants have good biocompatibility and relatively small environmental impact.

What is the environmental persistence of perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid)?

Perfluorooctane sulfonic acid (Perfluorooctanesulfonic Acid) has strong environmental persistence. This is because of its unique chemical structure, and the carbon-fluorine bond in the molecule is extremely stable. The carbon-fluorine bond energy is quite high, and it is difficult to be destroyed by chemical reactions under normal natural conditions, so it can be retained in the environment for a long time.
In the atmosphere, perfluorooctane sulfonic acid can be widely distributed around the world by atmospheric circulation. Although it has been transported over long distances, its structure is stable and it is not easily degraded. In water, it is well soluble and difficult to be decomposed by microorganisms. Many microorganisms lack enzyme systems that can destroy carbon-fluorine bonds, so they cannot be effectively degraded.
In the soil environment, PFOS is closely bound to soil particles and does not easily leach and migrate with water, but it also accumulates in the soil for a long time. Even after many years, its content in the soil is still difficult to see a significant decrease.
In addition, PFOS also shows strong accumulation in organisms. After ingestion by organisms, it is difficult to excrete through their own metabolism, and it will accumulate along the food chain, resulting in a significant increase in the concentration of organisms at the high end of the food chain. This property causes PFOS to persist in the environment for a long time, posing a continuous threat to ecosystems and biological health.
