If too much water-based dispersant is added, it may have the following effects on coatings or inks:

Stability Issues: An excess of dispersant can easily lead to a decrease in the stability of inks or coatings, making them prone to sedimentation and coagulation.

Shandong Kairui Chemistry Co., Ltd. is a company based in China that specializes in the production and export of various chemicals, including benzalkonium chloride (BKC) and dodecyl dimethyl benzyl ammonium chloride (DDBAC), which are commonly used as disinfectants and surfactants. If you're looking to import these chemicals, it's a good idea to reach out to them directly or through a trusted agent or importer/exporter platform to inquire about their products, pricing, and shipping options.

HEDP stands for 1-Hydroxyethylidene-1,1-Diphosphonic Acid. Its chemical structure is:

Here, it consists of a phosphonic acid group (─P(O)(OH)₂) with an additional hydroxyethyl (CH₂─OH) group attached to one of the phosphorus atoms.

The difference between HEDP solids and liquids is mainly reflected in their physical properties and uses. HEDP( 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid) has a colorless and transparent liquid state and a white crystal solid state. It has good chemical and thermal stability and is widely used as a chemical substance in industrial and agricultural fields.

Surfactants are not necessarily hazardous materials, but are determined by factors such as their specific type, concentration, use, and contact method. Some surfactants may pose certain hazards to human health or the environment, while others may be relatively safe.
Here are some considerations regarding the safety and potential hazards of surfactants:
Toxicity: Certain surfactants may have toxic effects on the human body at high concentrations, such as skin irritation, eye irritation, allergic reactions, etc. But when used at appropriate concentrations, most surfactants are relatively safe.
Biodegradability: Some surfactants may remain in the environment and have an impact on the ecosystem. Therefore, biodegradability is one of the important factors in evaluating the safety of surfactants.
Environmental impact: Certain surfactants may be toxic to aquatic organisms and may have negative impacts on aquatic ecosystems. Therefore, when selecting and using surfactants, attention should be paid to their impact on the environment.
Usage and concentration: The safety of surfactants depends on their usage and concentration. Reasonable use and strict adherence to the instructions can reduce potential hazards.
Individual differences: There are differences in the sensitivity of individuals to surfactants, and some people may have allergic reactions or other adverse reactions to certain surfactants.
Overall, surfactants themselves are not necessarily hazardous materials, but caution is needed in their selection, use, and handling to ensure compliance with relevant safety standards and regulations, and to minimize adverse effects on human health and the environment.

Surfactants play an important role in various applications, and their main functions include:
Reducing surface tension: Surfactants can reduce the surface tension of liquids, making it easier for liquids to wet solid surfaces. This characteristic gives it excellent penetration and cleaning performance in products such as cleaning agents and detergents.
Enhanced dispersion and emulsification: Surfactants can form micelles at the oil-water interface, dispersing oil droplets in water or oil, thereby enhancing the dispersion and emulsification between liquids, making them easier to mix and stabilize.
Wettability: Surfactants can reduce the contact angle between liquid and solid surfaces, making it easier for the liquid to unfold on the solid surface, thereby improving wettability and making the liquid cover the solid surface more evenly.
Foaming properties: Some surfactants have good foaming properties and can form stable bubbles in liquids, which are used in washing, cleaning, and personal care products.
Stabilizing lotion: surfactant can stabilize lotion, keep oil or water droplets dispersed, prevent precipitation or phase separation, thus extending the stability and shelf life of the product.
Thickening and viscosity adjustment: some surfactants can form gel structure in aqueous solution, thus increasing the viscosity and consistency of liquid, which is used to adjust the texture and fluidity of products.
Antistatic effect: Surfactants can form a protective film on the surface of objects, reduce the generation and accumulation of static electricity, and prevent the occurrence of static electricity.
In general, surfactants have many functions, such as wetting, cleaning, dispersion emulsification, stabilizing lotion, thickening viscosity, etc., and are widely used in detergent, detergent, personal care products, industrial products, pharmaceutical products and other fields.

Surfactants themselves are not fungicides, but they can help clean and remove bacteria in some cases, indirectly playing a certain bactericidal role. The main function of surfactants is to reduce surface tension, allowing water to better moisten and penetrate into the small bumps on the surface, thereby helping to clean and remove dirt and bacteria.
However, surfactants do not have the function of directly killing bacteria. To achieve the goal of completely killing bacteria, it is usually necessary to use specialized fungicides or disinfectants. These fungicides may include chlorides, peroxides, alcohols, phenols, etc., and have bactericidal effects on bacteria, viruses, and fungi.
In some cleaning products, surfactants may be used together with fungicides to achieve a dual effect of cleaning and disinfection. For example, in some detergents, cleaning agents, and personal care products, antibacterial agents may be added to ensure that the product has a certain bactericidal effect during use.
Overall, surfactants can help remove bacteria during the cleaning process, but to achieve thorough bactericidal effects, specialized bactericidal products or formulas need to be used.
