Abstract
Co-product streams derived from the manufacture of vegetable oil were further processed producing materials that possess strong absorbance of visible and ultraviolet light. The compounds contributing to the light absorbance were increased and standardized to produce a fat-soluble composition with consistent and strong absorbance of ultraviolet and visible light. The fat-soluble composition is a useful photoprotective agent for various applications including protection of herbicides and pesticides. In a preferred embodiment acidulated vegetable oil is blended to a constant absorbance of light between 190 and 400 nm and used in a formula to protect a field-applied herbicide.
