Desheng lets you understand Carbomer 980 in one article

Product Description

Carbomer is a high molecular polymer of acrylic acid-bonded allyl sucrose or pentaerythritol allyl ether. It is usually a loose white slightly acidic powder. It can produce high-efficiency thickening at low dosages, thereby preparing a wide viscosity range and Different rheological lotions, creams, gels and transdermal preparations. Carbomer **0 and **0 are commonly used Carbomer series materials. Today, the editor of Desheng mainly explains Carbomer **0.
 
The performance of different carbomers is slightly different. Different models represent different viscosities, and are called short rheology or long rheology. For example, carbomer **0 has short rheology and reaches ****0MPA.S at 0.5% viscosity, which is suitable for high viscosity. The product, carbomer **1 has long rheological properties, and the viscosity reaches ***0MPA at 0.5%. It is suitable for low viscosity products. The corresponding model of carbomer has ion resistance and ion resistance. Carbomer **0 has good thickening properties, high transparency, high viscosity, and strong suspending ability. Carbomer **0 is widely used in daily chemical products, such as skin care lotions, creams, transparent gel products, transparent skin care gels, hair styling gels, shampoos, shower gels, and disposable disinfection gels.
 
Carbomer **0 dissolution method
1. Pre-soaking method: *4 hours in advance, first add the carbomer to deionized water to dissolve it according to the actual production requirements without stirring. After the carbomer is allowed to absorb water naturally, there is no white powder on the surface and the solution cannot be seen White agglomerates shall prevail, stir evenly, and then add neutralizer (Carbo: neutralizer=1:1, Carbo: 5% neutralizer solution=1:4.5) and adjust the PH value to around 7 to increase In the thick state, use a circular tool or a disperser to mix evenly at low speed.
 
2. Homogenizer:According to the actual production ratio, add it to the homogenizer, and no white masses can be seen in the homogenization. Add neutralizer to form a gel, and then use a vacuum emulsification pot to suck out the air in the gel.
 
3. If you use common methods to dissolve, carbomer can not be stirred when added to water, such as one-while adding-while stirring will make carbomer form a white water sphere, the surface has absorbed water, and there is no water inside, it can be neutralized There are many white spots in the water, and a large number of bubbles are formed. The carbomer has a high viscosity, and the bubbles are difficult to eliminate by themselves. Even if the defoamer is added, it is difficult to eliminate it. In this case, the air bubbles can only be eliminated by using a vacuum pan.
 
Carbomer **0 precautions
Carbomer gum is a highly hydrophilic anionic polymer. It is a white loose powder with strong hygroscopicity. It can swell quickly in water but does not dissolve. The water dispersion solution is acidic, and the pH value of the 1% water dispersion solution is about 2.**3.5, and the viscosity is low. When neutralized with alkali, as the macromolecules gradually dissolve, the viscosity gradually rises, forming a clear solution at low concentrations, and a translucent gel at higher concentrations. It has the maximum viscosity and consistency at pH 6.5 to 7. When the water dispersion solution of the polymer glue is neutralized with alkali, a transparent and stable gel is formed.
 
In general, about 1.*5g of triethanolamine is needed to neutralize 1g of polymer glue. Avoid mixing with raw materials such as salts or acidic substances because it will reduce its viscosity. It is stable within the pH value of ***0. Triethanolamine is an alkalizing agent, used to adjust the pH value of the product, avoiding the combination with nitroso-containing agents, the maximum use concentration is 2.5%, avoiding and using formaldehyde as antiseptic Used in the same formula of the agent, it may cause skin irritation and allergic reactions.
 
It is claimed that there are countless manufacturers of Carbomer, and buyers must carefully analyze and distinguish when choosing. Desheng Technology is the real manufacturer of Carbomer, which only produces two models of Carbomer **0 and **0. With complete production equipment and mature production technology, the average daily output reaches ton level, and the price is favorable and the quality is guaranteed.
