20kg/Box Carbomer Configuration Guide The Configuration Process Of Carbomer Gel Cosmetics raw materials

1. When preparing the carbomer solution, the problem of carbomer formation may occur due to improper operation. There are several common methods to solve the problem of carbomer formation:

①. Sprinkle the carbomer on the water (particularly note that the carbomer is not added to the water) and let it stand overnight to make the carbomer fully swell;

②. Grind carbomer and glycerin (or propylene glycol, depending on the formula) in a grinding vessel, then add water and grind evenly;

③. Add a certain amount of water to the mixer, and slowly add the carbomer while stirring quickly. After the addition, continue to stir for 1-2 hours to fully swell the carbomer.

carbomer powder

The above three methods can obtain the colloid of carbomer. If you want to obtain the gel matrix, you must use triethanolamine or sodium hydroxide solution to adjust the pH to 6-10, and the resin particles must be uniformly dispersed in cold water, which can be 500 -Under high-speed stirring at 800 rpm, sieve the carbomer into the stirring vortex with a mesh, and finally obtain the gel matrix carbomer.

2. If the carbomer contains air bubbles to be avoided

①. Pre-soaking method: 24 hours in advance, add the carbomer powder into deionized water to dissolve it. This process does not require stirring. After the carbomer naturally absorbs water (the white powder on the surface is invisible, and the solution does not see white agglomerates). Standard), stir evenly, then add neutralizer to adjust the PH value to about 7 to reach the thickening state, and finally stir evenly with a disperser at low speed;

②. Homogenizer: add carbomer according to the actual production ratio to the homogenizer to homogenize until no white mass is visible, then add neutralizer to form a gel, and use a vacuum emulsifier to remove the air in the gel Just take it away.

Three, carbomer use precautions

Product packaging

Carbomer gel can not add reagents at will, such as soluble salt, strong acid solution, will make the carbomer gel system quickly thin; Carbomer itself has no nutrition, does not support the growth of bacteria or mold, but at the same time can not prevent bacteria And molds use the nutrients in the gel system to grow, so you can add preservatives or essential oils as needed; ultraviolet light has a certain effect on carbomer, so keep it away from light; when configuring skin care products, the carbomer concentration needs to be controlled Within 0.8%, if the concentration is greater than 0.8%, it will cause poor skin feel.
