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 hydroalcoholic 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.
