Title: Paquita Erazo-Majewicz: Innovator in Polysaccharide Applications
Introduction
Paquita Erazo-Majewicz is a prominent inventor based in Landenberg, PA (US). She has made significant contributions to the field of personal care and household care applications through her innovative work with polysaccharide compositions. With a total of 10 patents to her name, her inventions have paved the way for improved formulations in various consumer products.
Latest Patents
Among her latest patents is the invention of dispersible cationic polygalactomannan polymers. This invention relates to polygalactomannan compositions, specifically cationic guar gum compositions. These compositions, when crosslinked with glyoxal, form discrete guar particles that can be easily dispersed in water, facilitating subsequent processing such as washing. The guar and its derivatives are particularly desirable for use in personal care and household care products.
Another notable patent involves polysaccharide products with enhanced performance and clarity in phosphate ester surfactant-based aqueous formulations. This invention includes a personal or household care product that combines cationic, nonionic, or cationic/nonionic derivatized polysaccharides with a phosphate ester surfactant. The derivatized polysaccharide polymer is created by reacting the polysaccharide with the ester surfactant in the presence of water, caustic, and at least one surfactant. This innovative approach results in a derivatized polysaccharide that exhibits lower clarity in water compared to an aqueous surfactant system.
