Efficacy of carbomer 940:
Carbomer 940 is used in jelly gel formation. It can be used as an excellent floatation agent, stabilizer, emulsifier and matrix for pharmaceutical excipients. It is also an effective water-soluble thickener. 0.5% of the added amount can make jelly gel with jelly effect, slightly acidic, and the pH value of the dispersed system in 0.5% water is 2.7 - 3.5.
Recommended dosage of carbomer:
Generally, the addition amount is 0.2 to 1.0%, and in most cases, 0.2 to 0.5%. The 0.2 to 2% amount of carbomer resin is used as an emulsifier. The amount of 0.2 to 2% of carbomer resin is used as thickener. The 0.2 to 2% amount of carbomer resin is used as ointment. The 0.2 to 2% amount of carbomer resin is used as a gel.
How to use carbomer 940:
2% carbomer gel (50ML):
1. Weigh 1g carbomer dry powder and place it in a dry beaker with a scale of 50ml. If there is caking, please grind it with a spoon.
2. Add 25ml pure water, stir while adding, make carbomer fully absorb water and dissolve. This step is very critical. You must make carbomer absorb water fully. Generally, after adding water and stirring, you can put it for a few hours (you can configure it before going to bed at night, and it can be deployed the next day). Carbomer can fully dissolve. If you want to speed up, you can use a water bath to heat. It will be faster to stir while heating. Of course, even if heating can accelerate the process of carbomer's water absorption and swelling, it will take 10-30 minutes.
3. Drop the lye with the drop tube and stir it side by side to measure pH value. When the PH7 is adjusted, the gel is successful. (triethanolamine is enough for lye).
matters needing attention:
1, Carbomer must interact with the alkali triethanolamine to form a solid gel texture.
2. It is not resistant to acids, electrolytes, salts and other substances. Once it meets with salt, it will decompose into water
Packaging and storage:
Carbomer has a strong hygroscopicity. When storing, pay attention to sealing, and be careful 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. Once the product is used, it is best to place it in a sealed container with desiccant.
Desheng carbomer is packed in non-toxic polypropylene and nylon co extruded plastic bags, moisture-proof and airtight, and then packed in cardboard boxes. Carbomer is a polyelectrolyte, and sometimes static electricity is carried by rubbing or extruding resin particles. In case of spilling, please sweep up the dry powder with a broom first, and do not wash it with water, otherwise it will form a very slippery thin layer on the ground or equipment.
Desheng carbomer is more than 100 yuan / kg in tonnage, with large quantity and more favorable price. The carbomer 940 and 980 powders produced by Desheng carbomer are whiter and more fluffy than those in the market, and the transparency after dissolution is better.
