Particle size stable silicone emulsions

Particle size stable silicone emulsions

By using a nonionic surfactant as the primary emulsifier having an hydrophilic-lipophilic balance (HLB) greater than 13, at a concentration sufficient to provide 0.5-3 molecules per 100 square ANGSTROM of surface area of silicone particles; and a nonionic cosurfactant having an HLB less than 11, at...

Zusammenfassung:By using a nonionic surfactant as the primary emulsifier having an hydrophilic-lipophilic balance (HLB) greater than 13, at a concentration sufficient to provide 0.5-3 molecules per 100 square ANGSTROM of surface area of silicone particles; and a nonionic cosurfactant having an HLB less than 11, at a concentration sufficient to provide 5-15 molecules of emulsifier per 100 square ANGSTROM of surface area of silicone particles; aqueous emulsions containing low molecular weight silicones can be prepared which possess improved particle size stability. In particular, the low molecular weight silicones have a molecular weight less than 1,000 and a viscosity of not greater than 5 mm /sec. These emulsions can be used in applications relating to laundry pre-spotting, automotive bug and tar removal and hard surface cleaning.
