I believe that many people who mentioned Carbomer 980 will have a lot of questions like me. What is Carbomer 980? What is it for? Because of the epidemic, many things began to be paid attention to by more and more people, including Carbomer. The commonly used models are Carbomer 910, 934, 934P, 940, 941, 971P, 974P and so on. Today we understand Carbomer 980. The English name of carbomer carbomer 980 is Carbome980, literally translated from Chinese carbome 980, it can also be called carbomer resin, and its CAS is 9003-01-4.
Carbomer 980 Picture
Carbomer is soluble in water, glycerin, ethanol, and has the characteristics of a colloidal solution. The usual concentration is 0.1% to 3%, and its molecular structure contains 52% to 68% acidic groups, so it has a certain degree of acidity. The pH of 1% water dispersion is 2.5-3.0, and the viscosity is low. When neutralized with alkali, as the macromolecules gradually dissolve, the viscosity gradually rises, forming a clear solution at low concentration, and forming at higher concentration Translucent gel, the gel formed has the maximum viscosity and consistency at pH 6-12, and the viscosity decreases when pH <3 or pH> 12. Commonly used neutralizers are triethanolamine, ethylenediamine, laurylamine, sodium bicarbonate, sodium hydroxide, etc. Generally, 1g carbomer needs about 1.35g triethanolamine or 400mg sodium hydroxide to neutralize. Both strong electrolytes and sunlight can reduce the viscosity of the gel, and temperature also has a certain effect on the viscosity, but the relative change is small. The gel is best stored in a refrigerator in the dark.
Carbo 980 is a white loose powder. It has good thickening performance, high transparency, high viscosity, strong suspending ability, short rheological carbs of co-solvent system, and excellent suspension stability. The main characteristics are swelling and slightly acidic.
Carbomer 980 is used as the main material of disposable gel. It swells in water and adds a small amount of neutralizer (such as neutralizer and neutralizer 2) to form a highly transparent gel. Cross-linked polyacrylic resin, topical drug delivery system, suitable for skin care lotions, creams, alcohol-containing transparent gel products, transparent skin care gels, hair styling gels, shampoos, shower gels, the recommended dosage is 0.2-1.0%.
1. Long-term stirring or high-shear stirring after Carbo neutralization will cause viscosity loss
2. The presence of electrolyte will reduce the thickening efficiency of carbo resin
3. Long-term ultraviolet radiation will reduce the viscosity of carbomer.
Carbomer 980 can be stored for 2 years in a dry and sealed environment at room temperature. Do not use it if there is a peculiar smell or the storage time has expired. With the impact of the new crown virus, personal hygiene protection has received widespread attention. Washing hands frequently and wearing masks is a daily necessity for everyone. Desheng specializes in the research and development and sales of blood collection tube additives, chemiluminescence reagents, and color reagents for 15 years. Carbomer 980 has sufficient inventory at a favorable price.
