Name: Carbomer  Carbopol

Carbomer 940 Carbopol940  is a cross-linked polyacrylate polymer used in personal care gels and creams as a high-efficient rheology modifier. It is capable of providing high viscosity, excellent thickening and suspending performance with low-dosage. Its short flow (non-drip) properties are ideal for applications such as clear gels, hydroalcoholic gels, creams. When neutralized by alkali it forms sparkling clear water or hydroalcoholic gels and creams.

Formula Guidelines

Typical recommended dosage at 0.2~1.0 wt %.
To disperse Carbomer940 completely, it should be slowly and carefully sprinkled to dispersion medium while the mix is stirred rapidly to avoid formation of lumps; extremely high shear rate mixer should be carefully employed to avoid viscosity loss.
The ideal viscosity can be achieved at pH ranges of 5.0~10.0 when neutralized; In a hydoalcoholic system, a correct neutralizer must be chosen carefully based on the amount of alcohol to be gelled.
After neutralization, high-shear and lasting stirring should be avoided to keep stable thickening ability.

Matters Needing Attention
After carbomer neutralization, long-term stirring or high shear stirring will cause viscosity loss
presence of ions – electrolytes reduce thickening efficiency
Ultraviolet radiation and long term ultraviolet irradiation will make the carbomer gel less sensitive to ultraviolet radiation when its viscosity is reduced by pH>/=10.
Temperature change carbomer gel is not affected by temperature.
Microbe carbomer does not support bacterial mold growth, and bacterial mold growth does not affect gel properties. The conventional dosage of 0.2-0.4% can replace 3-7% of conventional emulsifier. Carbomer polymer has almost no property of surfactant. Therefore, adding 0.1-0.5% surfactant with low HLB value can adjust the oil phase particles to be smaller, so as to prepare white and fine cream products.
