Add the "Carbopol" resin(s) to the blend of oil, hydrophobic surfactant, and antifoam. Agitate slowly for 5-10 min. Premix the ammonium hydroxide and water. Slowly add the dilute ammonium hydroxide solution to the wetted-out mixture of "Carbopol" resin. For best results, add the solution at a constant rate. If a variable drive mixer is available, increase the agitation from slow to moderate or higher. Mix for 15-20 min after all the ammonium hydroxide has been added. Add the hydrophilic surfactant and mix for 5-10 min.
