Detailed Description

Carbomer 934P / 974P Water Soluble Carbomer For Thickening, Suspending & Stabilizing Description CARBOMER range are synthetic high molecular weight crosslinked polymers of acrylic acid, which confirm to USP./INF. specifications as "CARBOMER" Use CARBOMER range, are water soluble polymer use to : Thicken To produce wide range of viscosities and flow properties. Suspend Insoluble ingredients. Stabilize & Emulsify Emulsions Grade & Applications Grades Solvent used in process Carbomer 934P / 974P (Benzene free) Benzene Cyclohexane & ethyl acetate Carbomer 934P / 974P - High purity oral pharmaceutical grade for formulations. ¤ Gel, Lotion and ointment. ¤ Oral liquid, suspension and emulsion. ¤ Sustained release formulation by matrix system. ¤ Opthalmic gel and eye - lotion. ¤ Transdermal (skin) drug delivery. ¤ Taste masking. Advantages Thickning efficiency High viscosities at low concentrations. Uniform performance Reproducibility unattainable with natural gums. Safety Years of successful use of carbomers. Temperature stability Extended up to 750C heating or cooling Unaffected by aging Excellent self life. Microbial resistance Resists bacterial attack and does not support mold growth Versatility Although primarily used in aqueous systems with neutralization. It can also be used in solvent systems, with or without neutralization. Elegance Smooth and luxurious feeling. Chilling Properties On refrigeration CARBOMER gel can retaining the cool temperature level for 48 hours to 72 hours. Low temperature necessary for vaccines, toxoids, insulin and human albumin can be store in pre-refrigerated CARBOMER gel, making it as a suitable medium for transporting these medicines.
