Carbomer Gel Preparation Method2020-04-26
In the last article, we introduced the preparation method of carbomer gel, but in fact, carbomer gel has multiple preparation methods. In this article, we will introduce you to another preparation method of carbomer gel.
(2) Add 25ml of pure water and stir while adding to make the carbomer fully absorb water and swell. This step is critical. Carbomer must be fully absorbed.
Generally, after adding water and stirring, it can be fully swollen after being placed for a few hours. If you want to go faster, you can heat it with a water bath, and stirring while heating will be faster.
Of course, even if heating can accelerate the carbomer absorption and swelling process, it takes 10 to 30 minutes.
(3) Add the lye with a dropper, stir while adding, and measure the PH value at the same time. When adjusting the pH to 7, the gel is successful! (Using triethanolamine as lye)
(4) Make up the remaining amount of water. The total volume is about 50ML.
The formulated gel base can be directly mixed with other raw materials to prepare various gels, as long as the concentration of the carbomer is controlled within 0.8%, and it is recommended to be about 0.5%.
How to use: Only 0.5% concentration is needed to make a gel product with good appearance and texture. For example: To make a 100ml gel, just take 25g of the pre-prepared 2% polymer gel and add it to the 75ml formula.
2% concentration of transparent gel 100ml = 2gm gel powder + 98ml pure water + 0.5ml antibacterial agent + appropriate amount of neutralizer
