Abstract

A process for producing anionic, nonionic, amphoteric or cationic derivatized polysaccharide products which demonstrate high clarity in surfactant- based compositions. The polysaccharide polymer is reacted for a sufficient time and at a sufficient temperature in the presence of water, caustic, and at least one surfactant. The polysaccharide polymer may optionally be reacted with an oxidizing agent, hydrolytic or proteolytic enzymes, molecular weight reducing agents and a cationizing agent and nonionic agent. The formed derivatized polysaccharide has a lower clarity in water than in an aqueous surfactant system. The derivatized polysaccharide product can be used in personal care and or household care products.

Abstract

In this invention, a process for producing fermentable sugars derivable from biomass that contains polysaccharide, such as cellulose, which has been made increasingly accessible as a substrate for enzymatic degradation or other methods of depolymerization. The process of the present invention increases accessibility of polysaccharides, typically present in biomass and produces polysaccharides with increased accessibility. The polysaccharides with increased accessibility may be subsequently saccharified to yield fermentable sugars. These fermentable sugars are subsequently able to be fermented to produce various target chemicals, such as alcohols, aldehydes, ketones or acids.

The present invention provides an improved method of producing a stable acid denatured soy/urea adhesive having improved wet and dry strengths, with more efficient production and lower production costs. The method comprises combining urea with soy flour that has been acid treated until denatured and substantially free from urease activity. The soy flour is preferably lowered to a pH of 2.0 to 4.0 for at least 1 minute. Optionally, the method may also include adding a crosslinking agent, diluent or both to the soy flour/urea adhesive and/or adding an emulsified or dispersed polymer. Adhesives and dispersions prepared according to the methods of this invention offer increased stability and strength properties.

Abstract

A treatment for enhancing the activity of isothiazolinone compounds to control the growth of microbes in an aqueous system is disclosed, which comprises adding to said isothiazolinone compounds an amount of an alkylsulfosuccinate surfactant sufficient to improve efficacy of the isothiazolinone compound. Each alkyl group of the alkylsulfosuccinate contains at least 10 carbons.
