Title: Frederic Dalle: Innovator in Silicone Emulsions
Introduction
Frederic Dalle, an inventor based in Kraainem, Belgium, has made significant contributions to the field of silicone emulsions through his inventive methods. With three patents to his name, his work has a considerable impact on various industries, particularly in personal care and textiles.
Latest Patents
Among his latest patents, Dalle has developed innovative methods for creating silicone-in-water emulsions. One notable patent involves a silicone oil-in-water emulsion that contains a linear noncrosslinked silicone copolymer. The preparation process involves polymerizing an OH endblocked polydimethylsiloxane monomer with an amine functional trialkoxysilane monomer in the presence of a metal catalyst. This process is unique as the polymerization is interrupted by the emulsification of the copolymer, and a carboxylic anhydride is added prior to emulsification. The resulting emulsions are especially useful in personal care applications but also have valuable applications in textile fiber treatment, leather lubrication, fabric softening, release agents, water-based coatings, oil drag reduction, lubrication, and facilitating the cutting of cellulose materials.
In another patent, Dalle describes a method for making silicone in water emulsions. This method involves mixing a composition that includes at least one polysiloxane, an organosilicon material that reacts with the polysiloxane by a chain extension reaction using a metal-containing catalyst, at least one surfactant, and water. The mixture is then emulsified to produce an emulsion with a wide variety of silicone volume fractions, mono-disperse particle sizes, and molecular weight polymers.
