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, exnt 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
â« Short flow properties
â« High viscosity
â« High suspending, thickening and stabilizing ability
â« High clarity
Recommended Applications
â« Hair styling gels
â« Hydroalcoholic gels
â« Moisturizing gels
â« Bath gels
â« Hand, body and face lotions
â« Creams
Formula Guide
â« Typical recommended dosage at 0.2~1.0 wt %.
â« 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.
â« The ideal viscosity can be achieved at 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.
â« After neutralization, high-shear and lasting stirring should be avoided to keep stable thickening ability.
