Processes for converting lignocellulose to feedstock and downstream products are disclosed. The processes may include acid treatment of lignocellulose to produce a fermentation feedstock. In various instances, the processes include recovery or recycling of acid, such as recovery of hydrochloric acid from concentrated and/or dilute streams. Downstream products may include acrylic acid-based products such as diapers, paper and paper-based products, ethanol, biofuels such as biodiesel and fuel additives, and detergents.

The present invention broadly relates to aqueous cleaning compositions and the use thereof in cleaning soiled surfaces.

The present invention relates to a method for enhancing fragrance or perfume longevity of a composition by adding to the composition (a) a quaternary ammonium compound; (b) a cationic polysaccharide; (c) a nonionic polysaccharide; and (d) a fragrance material or perfume. In particular, the quaternary ammonium compound is a biodegradable quaternary ammonium compound. The composition has improved perfume longevity.
