7 features of Carbomer 940 you must know
The wave of carbomer remains high. In addition to being affected by the global epidemic, the speculation by middlemen and the flood of fake goods are also important reasons for the soaring value of carbomer. Behind the madness of Carbomer, what we need to understand is: what kind of characteristics does Carbomer 940 have and what should be paid attention to in the application process. As one of the first manufacturers to establish a Carbomer production project team for production , Here are the following 7 points for you, I hope you can benefit a lot.
|Chemical Name||Carbomer, polyacrylic acid, carbopol|
|Common model||Carbomer 940|
1. Carbomer 940 is white and loose; it is acidic, hygroscopic and has a slight special smell. It can be dissolved in water, ethanol, and sugar.
oil. The usual concentration is 0.1%～3.0%. Due to the large number of carboxyl groups in its molecule, special attention should be paid to the aqueous solution after neutralization with alkali
Use to reduce skin and mucous membrane irritation.
2. The neutralizer of Carbomer 940 can be sodium hydroxide, potassium hydroxide, potassium bicarbonate, borax, amino acids, polar organic amines such as triethanolamine. Laurylamine and stearylamine can be used as neutralizers in non-polar systems.
3. Although Carbomer 940 does not directly provide disinfection and sterilization function, it strengthens the disinfection and sterilization effect by extending the time that the alcohol stays on the skin, and can make the product have a good skin feel. Carbomer 940 gel Unstable, easy to grow mold and lose viscosity quickly when exposed to the sun, adding antioxidants can slow down the reaction.
4. Carbomer 940 transparency: the addition of a strong hydrophilic non-electrolyte (such as ethanol) will cause the polymer solution to flocculate. The carbomer ethanol gel is prepared by different operating processes. The high limit of the ethanol concentration of the finished product is different. When the concentration is too high, the finished gel will produce a little opalescence, reducing the transparency of the gel.
5. Carbomer 940 Viscosity: The degree of molecular expansion, pH value, and electrolyte concentration will affect the viscosity of Carbomer 940. The neutralized carbomer hydrogel is the most viscous between pH 6 and 11. If pH<3 or pH>12, the viscosity will decrease. The presence of strong electrolytes can also reduce viscosity.
6. Carbomer 940 is sensitive to salts and cations. When the concentration of soluble ions in the component exceeds 0.1%, the amount of the component should be controlled. If possible, use acidic, neutral or alkaline materials as the matrix of the main drug, use deionized water, and add salt after neutralization to grasp the degree of salt's influence on the system. High-valent ions (Ca, Mg, Fe, AI) will Serious damage to the system should be eliminated.
7. Packaging: It can be sealed with a moisture-proof and air-tight plastic bag, and then packed in a cardboard box. Carbomer has strong moisture absorption
Sex. Be sure to seal it when storing, and be careful not to absorb moisture and agglomerate in the exposed air. If there is a slight agglomeration, gently tap and press it to become a loose powder without affecting the thickening effect. After activation, it is best to place it in a sealed container filled with desiccant.
The products produced by our Desun’s Carbomer 940 speak to the praise of customers. Only the products that have stood the test and witnessed by time are good products. Carbomer viscosity can be customized according to customer requirements, and you can contact if necessary. Our sales or online sample trial application, as long as you trust us, all your problems are not a problem.
