Substantially nonaqueous concentrates for use in preparing stable, aqueous cleaner/degreaser compositions in the form of totally water soluble solutions comprise (a) at least one sparingly water soluble organic solvent having certain defined characteristics; (b) a solubilizing additive consisting of from approximately 0.1 to approximately 100 weight percent of a surfactant and from 0 to approximately 99.9 weight percent of a coupler, the solubilizing additive being present in an amount of approximately 3% to approximately 15% by weight excess over that minimally required to form a clear solution when the concentrate is combined with water; and (c) not more than 10.0 weight percent of water; (d) the concentrate forming a barely clear, totally water soluble solution when diluted with water to produce a solution having the desired cleaning/degreasing strength.

Cleaner/degreaser concentrate compositions

A low volatile organic component stable, aqueous cleaning/degreasing composition in the form of a macroemulsion is formulated by combining (a) a nonionic surfactant having certain specified characteristics; (b) an oligomeric or mono/polyfunctional hydrophobe having certain specified characteristics; and (c) water, the nonionic surfactant and hydrophobe being present in a weight ratio of between approximately 10:1 and 1:3 and the composition having a minimum composite score of 60% removal in the soilant marking removal test. Such compositions not only contain no or low amounts of volatile organic compounds but are environmentally safe and non-toxic and exhibit excellent cleaner/degreaser activity exceeding that exhibited by either the nonionic surfactant or hydrophobe component alone at equivalent or equal concentration.

Compositions for bonding fibrous substrates

Polymer compositions are described that confer an enhanced balance of wet and dry strength properties to a cellulosic substrate while leaving the substrate soft and porous. The compositions comprise a hydrophilic air-curing polymer and a polyol with a carbon to oxygen ratio of less than 3:1, typified by glycerol.

Air-drying compositions for treating fibrous substrates

The invention provides a stable polymeric additive useful for improving the wet strength of a cellulosic substrate. The additive is a water-soluble cationic thermosetting polymer incorporating a plurality of extralinear glycidyl quaternary ammonium groups. The invention also comprises a method of making such an additive.

Wet strength polymers
