The role and preservation method of carbomer 940 in hand washing gel

Carbomer 940 is white, loose, acidic, hygroscopic and slightly odorous, soluble in water, ethanol and glycerine

Oil. The common concentration is 0.1% ～ 3.0%. Because there are a lot of carboxyl groups in the molecule, the water solution should pay special attention to neutralization with alkali

Use it to reduce irritation to skin and mucous membrane. Since last year's epidemic, hand gel has always been a best seller, but do you know what role carbomer 940 plays?

Carbomer 940 is used in hand sanitizer gel. The main reason is its thickening, viscosity and permeability.

Compared with hand washing, most people prefer gel products. Carbomer can turn the solution into gel, and gel is more durable and convenient to use than liquid.

Carbomer can be used in hand sanitizer gel to achieve a good transparency. After neutralization, the carboxyl group is ionized. Due to the mutual repulsion effect of negative charges, the molecular chain is dispersed and stretched, which is extremely expansive and sticky. This kind of property undoubtedly makes carbomer one of the important raw materials for hand washing disinfection.

Carbomer 940 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 940 gel is unstable. It is easy to grow mold and lose its viscosity rapidly when exposed to sunlight. Adding antioxidants can slow down the reaction.

In addition, only a very low concentration (0.2% - 0.5%) can make some insoluble additives (particles, oil drops, etc.) achieve permanent suspension.

We should not only pay attention to its function in the product, but also pay attention to its storage. Because carbomer has strong hygroscopicity, it must be sealed during storage to prevent 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.
