 'ZW 2V EEN-4-6EL "DUTCH BOY" BEN-A-GEL is a highly purified magnesium montmorillonite which swells and gels in water with great efficiency. It is supplied as a soft milky-white powder of very fine particle size. Individual particles of BEN-A-GEL, which have been fully hydrated and separated in aqueous dispersion, attain an ultimate particle size of less than one micron.

In addition, it is useful as a suspending agent and for emulsify ing oil in water systems. Unlike organic gelling agents, such as gelatins, gums, etc., BEN-A-GEL is completely inorganic, and is not subject to microbiological degrada tion. Thixotropic Thickening and Gelling Efficiency -- When properly dis persed, good colloidal suspensions can be obtained with 1% of "DUTCH BOY" NLI 115519 BEN-A-GEL. At concentrations of 2 to 2.5%, a thick thixotropic gel is obtained. Incorporating 5% or more of BEN-A-GEL will yield firm, solid gels. The gels made with BEN-A-GEL do not thin out upon heating. Particle Suspension -- Hard settling of finely divided insoluble solidg in aqueous systems is eliminated by the use of about 1% of BEN-A-GEL. The con tinuous gel structure of the BEN-A-GEL -- water system cushions the settling particles and makes reincorporation easy. Emulsion Systems -- Stable emulsions of oils (mineral, vegetable, etc.) in water can be formed by using "DUTCH BOY" BEN-A-GEL in concentrations of 2% or less. Mixtures of water and immiscible organic liquids can also be emulsified. In smaller concentrations, BEN-A-GEL acts as an emulsion stabilizer when other emulsifiers are present. Aqueous systems containing BEN-A-GEL are compatible with a wide range of organic polar liquids. Methods of Incorporation Dry BEN-A-GEL should be sprinkled or sifted into the required water system, accompanied by constant high shear agitation. A high shear force is essential for uniform dispersion and maximum gelation. Sufficient shear for proper gelation is obtained with a homogenizer or colloid mill, such as a Waring Blendor or Premier Colloid Mill or their equivalents. Dilute BEN-A-GEL dispersions are readily prepared by thinning a 2.5-3.0% BEN-A-GEL masterbatch. The use of a roller mill or colloid mill is recommended for making masterbatch gels above 3% concentration, since the gel strength will be too stiff for thorough incorporation by stirring. These masterbatch gels have ex cellent storage stability and good thinning characteristics. In thickening oil-in-water emulsions, BEN-A-GEL should be dispersed in the water phase, as indicated, prior to emulsification. Fields of Application "DUTCH BOY" BEN-A-GEL as a gellant, suspension agent, and emulsifier in aqueous media lends usefulness in a wide variety of products, including the following: Creams Emulsion Paints Lotions Cleaners and Polishes Oil-in-Water Emulsions Textile Finishes Ceramics .Y v V ptmvoti CHEMICALS NATIONAL LEAD COMPANY General Offices 111 Broadway, New York 6, N.
