The Properties of Bronopol

With its English name, Bronopol, it is also known as bromo-2-nitro-1. It is a white to light yellow and yellowish brown crystalline powder, and it is odorless, tasteless, soluble in water, ethanol, propylene glycol, insoluble in chloroform, acetone, benzene and so on. It will decompose slowly in alkaline aqueous solution and corrode some metals, such as aluminum. Bronopol is toxic, which is irritating to eyes, skin and mucous membrane. It can cause congenital abnormality and is harmful to environment.

Bronopol is mainly used as antiseptic and bactericide. It is added in the process of shampoo, balsam and cream. Its concentration in cosmetics is 0.01%-0.02%, and it can also be used in detergent, fabric treatment agent and so on.

As a cosmetic preservative, bronopol is an ideal preservative. It has a wide antibacterial spectrum, good antibacterial and bactericidal effects on Gram-positive, negative bacteria, fungi and actinomycetes, it also has low inhibitory concentration and fast bactericidal effect, especially on pseudomonas aeruginosa. It is water-soluble and oil-soluble, the antibacterial activity is high in weak alkaline (pH = 7~9) and the formula of high concentration protein substance.

As a bactericide, bronopol can effectively control many plant pathogenic bacteria. The treatment of cotton seed can prevent and control the black arm disease and bacterial blight caused by cotton angular spot, and it has no harm to cotton. It can also be used for rice bakanae. The recommended concentration is 800-1000mg/L. It is also used in industrial circulating water, paper pulp, coating, plastic, cosmetics, wood, cooling water circulating system as well as sterilization, mildew prevention, anti-corrosion, algaecide and other industrial uses.

Bronopol is packed in plastic drums, avoiding metal containers. Bronopol is stored in a cool, dry and ventilated place. It is strictly prohibited to mix with strong oxidant, strong alkali, strong acid and food for loading, storage and transportation.

The Difference Between Nitrile Rubber and NBR LatexThe Difference Between Nitrile Rubber and NBR Latex

Affected by public health incidents, NBR latex is like a dark horse that has attracted the attention of the international market. Nitrile rubber and NBR latex are very different in use. 1. The difference in performance between nitrile rubber and NBR latex Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high abrasion resistance, good heat resistance, and strong adhesion. . Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Nitrile rubber is mainly used to make oil-resistant rubber products. Carboxylic nitrile latex is obtained by introducing methacrylic acid or methacrylate ternary copolymer during polymerization. Since the carboxyl nitrile nitrile latex introduces a more polar carboxyl group into the molecular backbone, it furt...

What is GLycolic Acid?

We like to focus on the ingredients of beauty products. But we prefer to touch the product and explore whether it really works. Alpha hydroxy acid is also known as AHA. It includes glycolic acid , lactic acid and citric acid. These products do not meet the needs. Now we analyze the most popular ingredient in the world - glycolic acid. Glycolic acid is a naturally occurring substance that is added to skin care products. It is good for the skin and restores skin elasticity and moisturization. The original state of glycolic acid is a powder composed of colorless crystals. It is tasteless. Let's first understand its benefits and its related products. The Benefits of Glycolic Acid Glycolic acid is very effective for skin treatment because of its high purity. The premise is safe and correct use. Many skin care products contain glycolic acid. Sensitive muscles can also be used. Glycolic acid is non-irritating and it can be used in skin care. Add more glycolic acid t...

Difference Between Sulfate And Sulfonate In Shampoo

Sulfates and sulfonates have two things in common. First, they're all anionic surfactants. Second, they are often used for personal care applications. But there are many differences. They have different molecular mechanisms. They have different functions and they have different raw materials. Sulfates Sulfate is a compound. It has carbon bonds and oxygen and sulfur bonds. They include substances such as sodium lauryl sulfate and sodium lauryl ether sulfate. At low pH, these substances plus the c-o-s bond hydrolyze to produce alcohol and inorganic sulfate. At a high pH, sulfate is stable in the base and, if ethoxylated to a relatively high level, produces a low-foaming alkali-soluble surfactant. Sulphates can be prepared by reaction of fatty alcohol or fatty alcohol ethoxylates with reagents such as SO3 or chlorosulfonic acid (CSA). The reason shampoo becomes thick foam in the shower is that it contains sulfate. Most shampoos and household cleansers contain su...
