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
âš«Â Â Â Short flow properties
âš«Â Â Â High viscosity
âš«Â Â Â High suspending, thickening and stabilizing ability
âš«Â Â Â High clarity
Recommended Applications
âš«Â Â Â Hair styling gels
âš«Â Â Â Hydroalcoholic gels
âš«Â Â Â Moisturizing gels
âš«Â Â Â Bath gels
âš«Â Â Â Hand, body and face lotions
âš«Â Â Â Creams
Formula Guide
âš« Typical recommended dosage at 0.2~1.0 wt %.
âš« 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.
âš« 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.
âš« After neutralization, high-shear and lasting stirring should be avoided to keep stable thickening ability.
Standard Packing: 20kg cardboard box with PE lining
