摘要:
This invention provides a dry blend pesticide composition which contains a fungicidal bicarbonate salt ingredient, and a spreader-sticker ingredient which is a crystalline clathrate complex of a urea constituent and a normally liquid spreader sticker constituent such as a nonionic surfactant. In a preferred embodiment all of the composition ingredients are water-soluble, and the composition is readily dispersible in an aqueous medium to form a sprayable pesticide solution.
摘要:
The present invention provides a fungicidal fertilizer composition which contains ingredients which are biocompatible for purposes of agricultural applications, and which are harmless to animals and humans. An invention fungicide composition in the form of a dry blend formulation remains non-caking and free-flowing under storage conditions. Illustrative of an invention fungicide composition is a formulation which has a content of sodium bicarbonate, potassium bicarbonate, potassium oleate, xanthan gum and a fertilizer-effective content of nitrogen, phosphorus and potassium elements. The combination of potassium oleate and xanthan gum functions as an effective spreader-sticker and film-forming medium when the composition is diluted with water for agricultural applications. When the aqueous medium is hard water, calcium oleate is formed which enhances the sticker properties of the aqueous fungicide composition in agricultural applications.
摘要:
This invention provides a fungicide composition which is capable of in situ generation of ammonium bicarbonate when applied to plant foliage in the form of an aqueous dispersion. The constituents include (1) an ingredient such as urea which slow-releases ammonia under aqueous alkaline pH conditions; and (2) an alkali metal bicarbonate ingredient which imparts alkalinity to the aqueous dispersion, and provides bicarbonate ions for combination with the released ammonium ions. A spreader-sticker ingredient is included to maintain the ingredients in contact with plant foliage over an extended period after application.
摘要:
A blast media for stripping contaminants from a solid surface comprises abrasive particles and a surfactant in the form of a granular surfactant-clathrate compound formed of a surfactant and a water soluble compound having clathration capability such as urea. The surfactant reduces the amount of water soluble residues which remain on the targeted surface and enhances the removal of dirt, grease and oil from the targeted surface.

The aqueous effluent from the wash and/or rinse cycles of a process for cleaning electronic circuit assemblies of rosin flux and other organic residues with an aqueous amine cleaning solution comprises treating the effluent with an alkaline earth metal oxide which reacts with the rosin flux to cause precipitation of an alkaline earth metal rosinate and the retention of free amine in aqueous solution.
摘要:
Improved one-part and two-part liquid products such as, e.g., mouthwashes, mouthrinses, toothpastes, gels and the like, for remineralizing subsurface lesions and/or mineralizing exposed dentin tubules in teeth contain a cationic component, an anionic component and a separating means for separating the cationic and anionic components. The anionic component contains water-soluble phosphate and fluoride salts, while the cationic component contains at least one partially water-soluble calcium salt and preferably at least one water-soluble salt of a divalent metal other than calcium. The tooth is treated with a mixed aqueous composition formed by mixing the cationic and anionic components with water and/or saliva. The mixed aqueous composition has a pH of from about 4.0 to about 10.0 and, in addition to dissolved calcium cations and dissolved phosphate and fluoride anions, contains a quantity of undissolved calcium salt. The use of the partially water-soluble calcium salt delays precipitation of the cations and anions in the aqueous composition until after the ions have diffused through the tooth surface to the subsurface and/or dentin so as to effect remineralization and/or mineralization, respectively.
摘要:
The present invention relates to remineralization, without demineralization, by applying to the teeth a composition which is present in either one or in two phases and which does not react to any large extent until introduced into the oral cavity and upon such introduction does not rapidly precipitate. One phase systems contain at least one water-soluble calcium compound, at least one other water-soluble, non-toxic compound containing a divalent metal different from calcium, and at least one water-soluble inorganic phosphate compound. If desired at least one water-soluble fluorine compound may be added to the system. In two phase systems one phase contains the calcium and the divalent metal compounds and the other the phosphate and optionally, the fluoride compound. In this way the ions which effect remineralization can be absorbed by the dental enamel and their subsequent, but controlled, reaction causes rehardening of demineralized areas in the dental enamel.
摘要:
This invention relates to chewing gum compositions and methods utilizing same which are useful to remineralize subsurface dental enamel. More specifically, this invention relates to stable, single-part chewing gum compositions containing calcium and phosphate salts which when applied to lesions in dental enamel result in remineralization of subsurface dental enamel and/or mineralization of tubules in dentin thereby counteracting caries and/or hypersensitivity.
摘要:
The present invention relates to plural compartment assemblies in which materials are stored in at least two separate compartments until the compartments are opened for use. More particularly, the invention relates to a dispensing tube whereby the utilization of a novel insert, a conventional dispensing tube can be divided into separate and discrete compartments at a low cost. The resulting dispensing assembly provides for dispensing more than one material from the same tube and even more particularly co-dispense predetermined proportions of incompatible materials simultaneously and effectively.
摘要:
The present invention provides an effective method for controlling foliage and root fungus infection in cultivated crops. A fungicide composition in the form of an aqueous formulation which is applied to pre-harvest crops contains ingredients such as pentachloronitrobenzene, sodium bicarbonate, sodium carbonate, potassium oleate, potassium octanoate and xanthan gum. The combination of potassium oleate, potassium octanoate and xanthan gum functions as an effective spreader-sticker medium for forming an adherent coating on plant foliage surfaces, and for saturating ground soil. The coating exhibits both immediate and long duration fungicidal activities.
