Abstract:
The invention relates to a wetting composition comprising a surfactant selected from a non-ionic, cationic, anionic and amphoteric surfactant in combination with from 10 to less than 50 wt % of at least one C10 to C14 alcohol and 10 to 30 wt % of a C4-C6 oxygen containing co-solvent, to methods for using the wetting composition and products containing the wetting composition.
Abstract:
Stripping solutions that may replace an etching resist ashing process are provided. The stripping solutions are useful for fabricating circuits and/or forming electrodes and/or packaging/bumping applications on semiconductor devices for semiconductor integrated circuits with good photoresist removal efficiency and with low silicon oxide etch rate and low metal etch rates. Methods for their use are similarly provided. The preferred stripping agents contain polar aprotic solvent, water, hydroxylamine, corrosion inhibitor, quaternary ammonium hydroxide and optional surfactant. Further provided are integrated circuit devices and electronic interconnect structures prepared according to these methods.
Abstract:
The presently disclosed subject matter is directed to a method of reducing microbes on a food surface and a hard surface. The disclosed antimicrobial composition comprises two cationic surfactants and one of the cationic surfactants is a quaternary ammonium cation. An additional disclosed antimicrobial composition may have a second cationic surfactant, a lantibiotic, and an aminopolycarboxylic acid.
Abstract:
Compositions including olefinic compounds are generally disclosed. In some embodiments, such compositions are cleaning compositions, and can be used to clean various surfaces and/or materials. In some embodiments, the olefinic compounds are derived from a natural oil or a natural oil derivative, for example, by catalytic olefin metathesis.
Abstract:
A fabric treatment composition is provided that includes at least one zeta potential modifier, a fluoropolymer and a hydrophobic agent with a melting point or glass transition temperature below 100 °C, for imparting fabric protection benefits to a fabric, such as improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better hand feel. Fabric treatment compositions can be used as a pretreatment prior to washing, through soaking, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and refresh the fabric protection benefits imparted to the fabric, with the proviso that an intermediate rinsing step essentially devoid of added surfactant-is used after the washing cycle and prior to the fabric treatment step. Following use of a first treatment composition, protective benefits are maintained and refreshed by means of a second treatment operation employing a second treatment composition. The second treatment composition may have lower active levels of the protective agents to provide for economical and periodic maintenance of the imparted fabric protection benefits.
Abstract:
A method of cleaning a profiled hard surface, e.g. a metal coated with a corrosion-resistant layer such as a zinc silicate primer, is provided. The method comprises the step of contacting the surface with a cleaning composition comprising (a) from 5 to 50% by weight of an anionic surfactant, (b) from 5 to 50% by weight of a first non-ionic surfactant having the general formula, R'-(AO) n -OH wherein R' is C 9 to C 20 alkyl; each AO unit is either -OCH 2 CH 2 - or -OCH 2 CH(CH 3 )- and n is greater than 6 and (c) from 5 to 50% by weight of a second non-ionic surfactant having the general formula, R'-(OCH 2 CH 2 ) n -OH wherein R' is C 9 to C 20 alkyl, and n is less than 6; each of said weight percentages being with respect to the total weight of (a), (b) and (c). The method is especially useful for cleaning the profiled internal surfaces of marine cargo tanks. Corresponding hard surface cleaning compositions are also disclosed in both concentrate and water diluted forms.
Abstract:
A detergent comprises an alkalinity source, a homopolymer of acrylic acid or a salt thereof, a homopolymer of methacrylic acid or a salt thereof, and a homopolymer of maleic acid or a salt thereof. Suitable weight ratios include a weight ratio of the homopolymer of methacrylic acid or a salt thereof to the homopolymer of acrylic acid or a salt thereof between approximately 1:3 and approximately 3:1, a weight ratio of the homopolymer of acrylic acid or a salt thereof to the homopolymer of maleic acid or a salt thereof between approximately 3:1 and approximately 1:6, and a weight ratio of the homopolymer of methacrylic acid or a salt thereof to the homopolymer of maleic acid or a salt thereof between approximately 2:1 and approximately 1:4.
Abstract:
The invention relates to a treatment method, which promotes the removal of dirt, for the surfaces of textiles and non-textiles. According to said method, cationically modified, hydrophilic nanoparticles, based on cross-linked polymers, are applied from an aqueous dispersion to the surface of the materials. Said cross-linked polymers consist of (a) between 60 and 99.99 wt. % of one or more ethylenically unsaturated monomers containing carboxyl groups, or the salts thereof, (b) between 0 and 40 wt. % of one or more water-insoluble, monoethylenically unsaturated monomers, (c) between 0.01 and 30 wt. % of one or more ethylenically polyunsaturated monomers, (d) between 0 and 25 wt. % of one or more monomers containing sulphonic acid and/or phosphonic acid, or the salts thereof, (e) between 0 and 30 wt. % of one or more water-soluble, non-ionic monomers. The dispersion of the hydrophilic nanoparticles can be stabilised with anionic, non-anionic and/or betainic emulsifiers and/or protective colloids. The hydrophilic nanoparticles have a particle size of between 10 and 2 mu m and are modified cationically by covering their surface with one or more cationic polymers, one or more polyvalent metallic ions and/or one or more cationic surfactants.
