Carbomer 940

INCI Name: Carbomer

Carbomer 940 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.

Features and Benefits

⚫     Short flow properties

⚫     High viscosity

⚫     High suspending, thickening and stabilizing ability

⚫     High clarity

Recommended Applications

⚫     Hair styling gels

⚫     Hydroalcoholic gels

⚫     Moisturizing gels

⚫     Bath gels

⚫     Hand, body and face lotions

⚫     Creams

Formula Guidelines

⚫ Typical recommended dosage at 0.2~1.0 wt %.

⚫ To disperse Carbomer 940 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.
