摘要
This invention relates to a composition containing an active chemical and a particulate polysaccharide matrix having improved water dispersibility and dispersion stability in aqueous solutions by the incorporation of a copolymer of a N-vinyl lactam monomer and a hydrophobic comonomer. The improved properties of the matrix promotes its use as a dispersing agent in a wide variety of formulations where soil and skin substantivity or sustained release of the active chemical is required, as in pharmaceutical, pre- and post-emergent agrochemical and cosmetic formulations. The invention also pertains to the preparation and use of formulations based on the use of polysaccharide/copolymer matrix of this invention.
