摘要:
Stable microbicidal disinfectant compositions comprising a complex of a halogen, a nonionic surface-active agent, and an -onium salt of an alkyl amine characterized by a negative reaction to standard tests for free halogen, no loss of halogen when boiled in an aqueous solution, and having microbicidal activity.
摘要:
A germicidal, disinfecting and antiseptic composition comprising alkoxy aliphatic amine derivatives of the formula (I) or (II) and an organic or inorganic compound capable of blocking metals. The composition can be used in germicides, disinfectants, cosmetics, domestic sundries and city water, and to remove the microbial pollution and other contamination problems in industrial processes.
摘要:
Two compositions containing respectively a cation and an anion, such as calcium ion and phosphate ion, are sequentially applied to dental enamel resulting in remineralization of subsurface dental enamel.
摘要:
Demineralized tooth enamel is remineralized by first forming a metastable mixture by mixing a solution containing a soluble calcium salt with a solution containing a soluble phosphate salt, the mixture having a pH of from about 2.5 to about 4 and a ratio of calcium ions to phosphate ions of from 0.01 to 100; and second, applying the metastable mixture to the tooth surface. Preferably, the second solution contains a soluble fluoride salt and the metastable mixture has a pH of about 2.7.
摘要:
A method of treating and protecting plants from fungal infections by topical and systemic application with hypophosphites is described. The hypophosphites are selected from the group consisting of hypophosphorous acid (H.sub.3 PO.sub.2) and its salts with monovalent, and multivalent inorganic ions.
摘要:
The present invention relates to a phosphine-developing pesticide which comprises at least one phosphide selected from the group consisting of magnesium phosphide and aluminium phosphide, a thermally decomposable material and polyethylene oxide having a molecular weight of between 4000 and 12000 and to a process for producing the same.
摘要:
The invention discloses as new fungicidal compositions of matter dispersed micelles of overbased copper naphthenates in non-phytotoxic spray oils prepared metathetically. Each micelle contains a combined alkaline earth metal to reduce phytotoxicity of the dispersions. The alkaline earth metal may be present partly as naphthenate in the outer protective layer of the dispersed micelles. The inner core of the micelle is mainly copper hydroxide but some alkaline earth metal hydroxide may also be present. The mole percent of alkaline earth metal to copper ranges from about 1 to about 7 and the preferred metal is calcium. The micelles form clear fungicidal dispersions in spray oils.
摘要:
The bacteridical substance comprises a support for iodine formed from a condensate of propylene oxide with an aliphatic polyol soluble in water, of the formula: Polyol -(C3H6O)n, in which the ''''polyol'''' comprises three to six alcohol functions, especially glycerin, sorbitol, erythritol, penta- and dipenta-erythritol, trialkanolamines, especially triisopropanolamine, and in which 3

摘要:
A tablet of chlorine releasing solid compound having substantially parallel plane faces in which the surfaces of the edge between the faces is sealed by water impervious and water insoluble material, which may be a continuous band of insoluble material which adheres to the compound, may be a band comprising a flexible sheet material attached to the edges of the tablet by a water insoluble adhesive, at least one of which is water impervious, or may have one of a number of alternative constructions comprising a self-adhesive tape, a coating of paint or synthetic resin, or a coating of wax. Alternatively the continuous band may be the side of a cup-like member and the tablet is sealed within the cup-like member by water impervious insoluble sealing material.
