Dispersion and Hydration of Carbomers

From Silverson Machines, Inc.
 

 
Carbomers such as Carbopol®* are water soluble vinyl polymers, used as emulsifying, stabilizing, suspending, thickening and gelling agents in many industries. They are widely used in manufacture of cosmetics and toiletries, including gels, creams and lotions, detergents, and air fresheners. The gelling effect is activated in two stages, firstly the dispersion and hydration of the carbomer, and secondly "neutralizing" the solution by the addition of chemicals which increase the pH. Neutralizing agents include triethanolamine (TEA), sodium hydroxide and potassium hydroxide. These problems can be overcome using a Silverson high shear mixer to disperse the Carbomer and other ingredients, and for emulsifying oil and aqueous liquid phases. Dispersion Dispersion is completed in a fraction of the time taken by conventional means, avoiding the risk of over shearing the polymer. Operation is described below. Neutralization Silverson mixers can be used for the neutralization stage, depending on percentage and grade of carbomer. For high viscosity products, a low shear stirrer/scraper would be used.
