摘要:
Embodiments of the present invention provides for superior all-in-one air cleaner/odor eliminator, surface disinfectant and surface multipurpose/all purpose cleaner all purpose or multipurpose cleaners that are compliant with local and federal VOC (volatile organic compound) regulations, are not flammable, avoids use of ingredients which detract from the worlds food supply, are mild to surfaces and materials of construction with a near neutral pH, clean with less work and in a shorter period of time compared to currently commercial available cleaners while also providing superior air cleaning/odor elimination and broad spectrum disinfection of surfaces.Embodiments of the present invention also provide for a superior all-in-one air cleaner/odor eliminator, surface disinfectant and surface multipurpose/all purpose cleaner which uses environmentally friendly components, has a near neutral pH which allows it to be used on various surfaces, which is safe for use on colored surfaces or items, which has low VOC's, which has no abrasives, which has no phosphates or phosphorous containing compounds, which has no anionic surfactants, which has no added electrolytic salts, which has no heavy metals such as zinc, copper and other transition metals, which has no harsh or sensitizing preservatives, which has no silicates or silicones. The formulation according to the present invention has superior cleaning of soils, stains or grease and requires less work to clean surfaces compared to currently available commercial cleaners while also providing superior air cleaning/odor elimination and broad spectrum disinfection of surfaces.
摘要:
Abrasive articles comprising a cured thermosetting binder and abrasive grains. The binder is prepared with a poly-functional molecule which contains at least two functional groups selected from the group consisting of carboxyl, anhydride and amine, and a (hydroxyalkyl)urea crosslinking agent containing a single urea group, at least two hydroxyl groups, and have at least two carbon atoms disposed between the urea group and each of the hydroxyl groups. The abrasive articles comprise bonded, nonwoven or coated abrasive articles.
摘要:
A polyurethane, soluble or dispersible in water, prepared from organic diisocyanate diols or other isocyanate reactive materials and a 2,2-hydroxymethyl-substituted carboxylic acid diol neutralized with a cosmetically acceptable organic or inorganic base and formulated into a hair fixative composition containing low amounts of volatile organic solvent. The present invention is also directed to a process for the preparation of polyurethanes comprising dispersing the polyurethane after at least 70% of the theoretical isocyanate reaction has taken place, but before completion of the reaction.
摘要:
A coating or impregnating composition containing an aqueous dispersion of a vinyl addition polymer and a reactive coalescent is provided. The reactive coalescent contains at least one acetoacetate grouping, or an enamine thereof. In one embodiment the reactive coalescent also functions as an emulsion polymer crosslinker.
摘要:
A process for encapsulating a wide variety of target materials, including both hydrophilic and hydrophobic materials, employs condensation of two reactive compounds to form shells around core phase particles including target material dispersed in a continuous phase. One of the reactive compounds has at least two active methylene functional groups per molecule, the other being an active methylene-reactive crosslinking agent. Either type of the reactive compounds can be dispersed in the continuous phase, the other being dispersible in the core phase. Applications include controlled release microencapsulation of agriculture chemicals and biocides.

摘要:
A textile treatment composition which imparts anti-wrinkling properties to textiles treated therewith, said textile treatment composition comprising a polyhydroxyalkylurea crosslinking agent having at least two urea moieties. Textiles treated with the compositions of the invention display a significant reduction in wrinkles compared with nontreated textiles. Moreover, the treated textiles have a tactile sensation of feeling soft and retain their smoothness after laundering.
