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.

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...

Two Different Types of Anionic Surfactants

  Anionic surfactant is a kind of product with the longest history, the largest output and the most varieties among surfactants. According to the structure of hydrophilic groups, anionic surfactants can be divided into sulfonates and sulfates, which are the main categories of anionic surfactants.    The  anionic surfactants definition  is a must-known concept for many people working in the chemical industry. The various functions of surfactants are mainly manifested in changing the properties of the liquid surface, liquid-liquid interface and liquid-solid interface, of which the surface (interface) of the liquid is the most important.   Sulfate-type anionic surfactants mainly include fatty alcohol sulfate (also known as primary alkyl sulfate) and secondary alkyl sulfate ： 1.  Fatty alcohol sulfate (ester) salt (FAS or AS). The general formula of fatty alcohol sulfate is: ROS0-3M+, R is alkyl, M+ is sodium, potassium, ammonium, ethanolamine and other ca...

Polyether Polyol Manufacturing Process

  Synthesis of DMC-based polyether polyol by a continuous method   A certain amount of DMC catalyst is taken and uniformly dispersed in a certain amount of small molecule initiator. Add 0.5 kg of the mixture of the initiator in the small test reactor. The vacuum was replaced 1-2 times with N2, and the N2 pressure was maintained at 0.1 MPa. After heating, stirring and raising the temperature to a certain temperature, the quantitative PO was introduced into the continuous autoclave with nitrogen gas for induction. When the induction is successful (the temperature in the kettle rises and the pressure drops), the PO is continuously passed to carry out the reaction. Open the outer loop and continue to pass the PO into the continuous kettle.   When the liquid in the reaction vessel is full, the PO, DMC catalyst and the initiator are continuously added to the kettle at a certain ratio and a certain speed through the power system. Continuous discharge is started when a certain pr...
