Carbomer U20: A Power Booster For Industrial Formulations, Innovative Drive For Multi-Solvent Compatibility And Strong Stability

Tips:

--There are two main thickening mechanisms of carbomer, including neutralization thickening and hydrogen bonding thickening.

1.Neutralization and thickening

• Because it contains a certain acid group, it needs alkaline neutralization in the process of application. After being neutralized by alkalinity, the carboxyl group of capo resin is ionized.

• Due to the mutual repulsion of negative charges, the curled molecular chain is extended to a state of great expansion, increasing the original volume to about 1000 times, thus playing a role of thickening.

• Common neutralizers include sodium hydroxide, potassium hydroxide, potassium bicarbonate and triethanolamine (pH 7 or so, you get a crystal clear gel), which is why Carbomer is sensitive to ions.

2.Hydrogen bonding thickening

• As a carboxyl donor, carbomer molecules can be thickened by bonding with one or more hydroxyl groups to form hydrogen bonds. This reaction mechanism takes time. Common hydroxyl donors include nonionic surfactants and polyols.

Basic properties:

• Carbomer U20 is a white loose powder with short rheological properties, high viscosity, high transparency, low ion resistance and low shear resistance. It is effective in thickening all types of solutions. It is suitable for thickening, suspension and emulsification in the formulation of cosmetics or pharmaceuticals.
• Using Tips:After carbomer completely dissolves water, it needs to add alkaline substances to neutralize to achieve good results, such as triethanolamine, sodium hydroxide and so on.

Performance:

1. It has the function of thickening, suspending and stabilizing.
2. Short rheological.
3. High transparency.
4. The viscosity of Carbomer resin is not affected by temperature.
5. Topical delivery system, crystallizing gel, water or alcohol solvent.
