摘要:
A cationic oil-in-water emulsion, for addition to detersive compositions, comprising hydrophilic cationic polymers, a surface-active, anionic polymer that is capable of adsorbing at an air-water interface or an oil-water interface and/or is oil-soluble, and a hydrophobic benefit agent in the oil phase made by adding the benefit agent to a hydrophobic liquid; thickening the oil phase with an organophillic smectite clay reacted at clay platelet surfaces to make the clay platelet surfaces hydrophobic while the edge surfaces of the clay remain hydrophilic, such that the organophillic smectite clay is adsorbed at an oil/water interface in the emulsion, and one of the hydrophilic, cationic polymers has a cationic nitrogen content of at least 6% by weight, that is incompatible with anionic surfactants, being insoluble in anionic-surfactant solutions containing an amount of 3% or higher of an anionic surfactant, and another hydrophilic cationic polymer has a cationic nitrogen content of at least 0.1% by weight and has a molecular weight of at least 600,000 Dalton.
摘要:
Reactive geocomposite mats, and their method of manufacture, for treating contaminants in sediment, soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, that is needlepunched to an outer geotextile sheet layer to provide a high loft, structurally secured, pre-formed geotextile having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as “contaminant-reactant material” or “contaminant-reactive material”) throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed, needlepunched geotextile. A liquid-permeable outer geotextile sheet then is secured to the filled geotextile, preferably by heating upwardly extending fibers of the pre-formed geotextile mat to prevent the powdered or granular material from escaping from the geotextile during transportation and installation.
摘要:
Paper is made by providing an anionic aqueous emulsion of a size, usually a reactive anhydride size, and mixing it into a cellulosic suspension prior to drainage of the suspension to form a sheet which is then dried to provide paper (including paper board). The emulsion is preferably stabilised wholly or mainly by 0.5 to 30 parts by weight (per part by weight size) of water soluble, anionic, polymeric stabiliser, which is preferably anionic starch. Alternatively, the emulsion may be added to the cellulosic suspension while it is anionic, before mixing retention into it. The emulsion may be added to the cellulosic suspension after cationic retention aid has been added to it, the emulsion being added with, before or after mixing anionic microparticulate material or other anionic bridging aid, prior to drainage of the suspension.

摘要:
nuc-PP nanocomposite is made from the mixing of nuc-PP with olefin elastomer and organoclay, and optionally, a dispersion agent. Unexpectedly, processing properties such as higher melt flow, and performance properties such as higher toughness and higher stiffness, are obtained when compared with commercially available PP nanocomposite.

A liquid cleansing composition comprising a cleansing surfactant, an adsorbed skin-care agent, adsorptive polymeric particles having an adsorption capacity of at least 2 g of skin care agent per gm of dry polymeric particles, a polymeric thickening agent having a molecular weight in the range of 500,000-10,000,000 Dalton, a water-soluble polymer having a molecular weight in the range of 200-50,000 Dalton, and a hydrophilic liquid, the said cleansing composition having the following features i) the low molecular weight, water-soluble polymer component functions as a foam-boosting and thixotropy-boosting agent; ii) the ratio of the Brookfield viscosity at 1 rpm of spindle speed to the Brookfield viscosity at 100 rpm of spindle speed is at least 10; and iii) the foam-volume is at least 20% higher with the water-soluble, polymeric, foam-boosting component than without it.
摘要:
The use of a coupling agent containing a mercapto, disulfide, tretrasulfide and/or polysulfide end group provides a mercury removal media having increased reactivity, stability, and mercury removal ability. The mercury removal media described herein is prepared by reacting an organophilic clay containing onium ions with a mercapto, disulfide, tetrasulfide, and/or polysulfide end moiety. Alternatively, the clay can be made organophilic by onium ion reaction prior to or simultaneously with the coupling reaction of the mercapto- or sulfide-end group-containing coupling agent.

The use of a sulfur-impregnated organoclay provides a mercury or arsenic removal media having increased reactivity, stability, and mercury removal ability. The Hg/As removal media described herein is prepared by impregnating an organophilic clay with elemental (free state) sulfur. Alternatively, the clay can be made organophilic by onium ion reaction prior to or simultaneously with impregnating the organoclay with sulfur.
摘要:
Layered phyllosilicates are useful for adsorbing and/or binding to cholesterol and, thereby, reducing blood cholesterol in a patient. Accordingly, provided herein is a method of reducing hypercholesteremia in a mammal comprising administering to said mammal a protonated and at least partially exfoliated layered phyllosilicate material alone and in combination with other cholesterol-reducing agents in an amount effective to reduce hypercholesteremia in said mammal.
