CAS9003-01-4| 7 features of Carbomer 940

Descripción del producto

What are the characteristics of carbomer **0 and what should be paid attention to in the application process? Here are seven points for you, hoping to benefit you.

1. Carbomer **0 is white and loose; It is acidic, hygroscopic and slightly odorous, soluble in water, ethanol and glycerol. The common concentration is 0.1% ～ 3.0%. Due to the large amount of carboxyl group in its molecule, the aqueous solution should be used after neutralization with alkali to reduce the irritation to skin and mucous membrane.

2. The neutralizer of carbomer **0 can be sodium hydroxide, potassium hydroxide, potassium bicarbonate, borax, amino acids and polar organic amines such as triethanolamine. Laurylamine and Stearylamine can be used as neutralizers in nonpolar systems.

3, Carbomer **0 itself does not directly provide disinfection and sterilization function. It strengthens the disinfection and sterilization effect by prolonging the time of alcohol residing on the skin, and can make the product have a good skin feeling. Carbomer **0 gel is unstable. It is easy to grow mold and lose its viscosity quickly when exposed to sunlight. Adding antioxidants can slow down the reaction.

4, Carbomer **0 transparency: strong hydrophilic non electrolytes (such as ethanol) will flocculate the polymer solution. Carbomer ethanol gel is prepared by different processes. The ethanol concentration of the finished product is different. When the ethanol concentration is too high, the finished gel will produce a little milky light and reduce the transparency of the gel.

5, Carbomer **0 viscosity: the degree of molecular expansion, pH and electrolyte concentration will affect the viscosity of carbomer **0. The carbomer hydrogel is most viscous between pH6 and *1 after neutralization. If pH < 3 or pH > *2, viscosity will decrease. Strong electrolyte can also reduce viscosity.

6. Carbomer **0 is sensitive to salt and cation. When the concentration of soluble ion in the component exceeds 0.1%, the dosage of carbomer **0 should be controlled. If possible, acidic, neutral or alkaline materials should be used as the matrix of the main drug, deionized water should be used, and salt should be added after neutralization to master the influence of salt on the system. High valence ions (CA, Mg, Fe, AI) will cause serious damage to the system and should be eliminated.

7. Packing: it can be sealed with moisture-proof and airtight plastic bags, and then packed in cardboard boxes. Carbomer is highly hygroscopic. During storage, attention must be paid to sealing, and care must be taken to avoid moisture absorption and caking in the exposed air. If there is slight caking, it can become loose powder by gently patting and pressing, which will not affect the thickening effect. After use, it is better to put it in a sealed container with desiccant.
