  • Patent number: 7279452
    Abstract: A sanitizing applicator for applying a liquid sanitizer to a surface. The sanitizer may be a quaternary ammonium compound (QAC)-based or chlorine-based sanitizer containing positively charged ions at an effective concentration level for killing a predefined percentage of microbes present on the surface. The applicator includes a breakable internal reservoir for retaining a quantity of the sanitizer, and a positively charged nonwoven fabric covering the reservoir. The fabric is constructed using a positively charged binder to bind together the strands of the fabric, and is optionally treated with a positively or neutrally charged surfactant. The positive charge of the fabric prevents the fabric from neutralizing the positively charged ions in the sanitizer when the breakable internal reservoir is broken and the sanitizer is applied to the fabric.

  • Patent number: 7226898
    Abstract: The use of an agent containing surfactant components chosen from sulfonic acids or sulfonates, alkylamine oxides, ethercarboxylic acids, and alkylether sulfates, in total amounts of 0.01 to 1 wt. %, preferably 0.05 to 0.5 wt. %, with respect to the entire agent, and also one or more percarboxylic acids chosen from a) those peracids or salts of peracids with general formula (I) R2—O2C—(CH2)x—CO3H in which R2 is hydrogen or an alkyl group with 1 to 4 carbon atoms and x is a number from 1 to 4, and/or b) phthalimido-percarboxylic acids (II), in which the percarboxylic acid segment contains 1 to 18 carbon atoms, and/or c) compounds of the formula (III) R1—CO3H in which R1 is an is an alkyl or alkenyl group with 1 to 18 carbon atoms, for disinfection purposes in CIP processes.

  • Patent number: 7208456
    Abstract: The present invention is a composition comprising a surfactant blend of nonionic and anionic surfactants useful for the removal of oligomer deposits from polyester fibers and polyester processing equipment. The composition of the present invention includes a surfactant blend of an ethoxylated sorbitan ester and at least one additional nonionic or anionic surfactant. The combination of the ethoxylated sorbitan ester and additional surfactants used in the invention surprisingly has a synergistic effect on the removal of oligomer deposits from polyester fibers and polyester processing equipment.

  • Patent number: 7008918
    Abstract: A rinse agent composition is provided. The rinse agent composition includes a sheeting agent for promoting draining of sheets of water from a surface, and a humectant. The humectant is a component which retains at least 5 wt. % water when the humectant has been contained at an equilibrium of 50% relative humidity and room temperature. The sheeting agent and humectant are preferably provided at a ratio of between about 5:1 and about 1:3. A method for rinsing a substrate surface in the presence of high solids containing water is provided. High solids containing water is generally considered to be water having a total dissolved solids content in excess of 200 ppm.

  • Patent number: RE40495
    Abstract: An article for sanitizing a surface with a sanitizing solution while maintaining the concentration level of a sanitizer in the sanitizing solution at an effective concentration level. A substrate that absorbs and holds the sanitizing solution is treated with a sanitizer release polymer composition. The substrate may be a woven, nonwoven, or knit fabric, a foam or sponge, or the like. The sanitizer release polymer composition may include a cationic or nonionic surfactant or binder that is operable to maintain the concentration level of the sanitizer at the effective level during prolonged periods of use.
