摘要:
Blisters of the skin are treated by applying to the skin over the blister a flexible moisture-containing hydrophilic hydrogel patch that includes a backing support such as paper, cloth or plastic and a water-based hydrogel layer applied to the backing. The hydrogel layer comprises a hydrophilic natural or synthetic polymer to provide body dispersed in water and can be a tacky adhesive. The polymer can comprise any high molecular weight hydrophilic carbohydrate such as karaya, cornstarch, or a kelp gel and/or a synthetic hydrophilic polymer such as polyacrylamide or polyacrylic acid. A humectant such as a polyhydric alcohol, keeps the gel layer moist. A solute such as salt, protein, sugar or an alcohol is dissolved in the water in a quantity sufficient to raise the osmotic pressure enough to maintain the hydrogel layer in a hypertonic state with respect to the blister. The hydrogel which hydrates the normally dry upper layer of skin forms a hydrophilic bridge with the patient's skin that allows fluid to be drawn by osmotic pressure from the blister through the normally dry stratum corneum into the patch. In addition, the hydrogel very quickly significantly dimishes the pain secondary to skin burns and blisters.

The present invention relates to a cleansing composition comprising at least one compound selected from N-long chain acylamino acids represented by formula (I): 1 (wherein n represents 1 or 2; and R represents a saturated or unsaturated hydrocarbon group having 5 to 23 carbon atoms), and salts thereof.
摘要:
The present invention relates to compounds being esters of 5-aminolevulinic acids or pharmaceutically acceptable salts thereof, including compounds of formula (I) R22NnullCH2COCH2nullCH2COnullOR1 (wherein R1 may represent alkyl optionally substituted by hydroxy, alkoxy, acyloxy, alkoxycarbonyloxy, amino, aryl, oxo or fluoro groups and optionally interrupted by oxygen, nitrogen, sulphur or phosphorus atoms; and R2 represents a hydrogen atom or a group R1, and both R2 groups may be the identical or different), and their use in diagnosis and photochemotherapy of disorders or abnormalities of external or internal surfaces of the body, and products and kits for performing the invention.
摘要:
The bioavailability of a pesticide can be increased by formulating the pesticide as a stable aqueous dispersion of particles in the micron or submicron range. Such a formulation has the further advantage of substantially reducing or eliminating the need for organic solvents. Moreover, the stable aqueous dispersion provides a means of preparing a one part formulation of a plurality of pesticides which would be otherwise unstable in each other's presence.
摘要:
Chemically stable, insecticidally active pellets having a low moisture content and at least about 95% active ingredient are described, as well as a method for manufacturing them. The active ingredient is selected from a class of N-hydrocarboyl phosphoroamidothioate and phosphoroamidodithioate compounds as described in the specification. The pellets generally have a moisture content of about 0.5% by weight or less, preferably less than about 0.3% by weight. The pellets can be produced by one of two types of processes as described in detail, including a high pressure axial extrusion process and a low pressure basket extrusion process.

Compositions and lures are described which provide synthetic chemical attractants which function as highly effective attractants for male and female moths, primarily moths of the family Noctuidae. In one aspect, the attractants provide an effective attractant amount of vapor of 3-methyl-1-butanol, 3-methyl-1-pentanol or mixtures thereof. In another aspect, the attractants provide vapor blends of acetic acid and one or more compounds selected from the group consisting of 3-methyl-1-butanol, 3-methyl-2-butanol, and 3-methyl-1-pentanol. By attracting male and female moths to traps or baits, the chemical attractants provide a means for detecting, surveying, monitoring, and controlling the moths.
摘要:
An allantoin-containing skin cream composition can comprise allantoin and at least one anionic or nonionic emulsifier that is substantially hydrophilic and is soluble in water. The pH of the composition is in a range of from about 3.0 to about 6.0; preferably, the pH of the composition is from about 5.0 to about 6.0. The composition can further comprise an acidic anionic polymer. A preferred acidic anionic polymer is a carboxypolymethylene polymer. The composition can further comprise a carbohydrate polymer such as galactoarabinan, polygalactose or polyarabinose. The composition can additionally comprise other ingredients such as herbal extracts, an antioxidant component, an emollient component, a chelator, a solvent component, or a preservative component. The composition is useful as a skin protectant.
摘要:
Skin antiseptic composition dispensers and methods of use are disclosed. The skin antiseptic composition dispenser may include a container with one or more walls that are substantially impermeable to ethylene oxide gas during normal ethylene oxide sterilization processes. In some embodiments, the container may include flexible walls free of metallic foil barrier layers. The containers may also include one or more vents in addition to one or more openings used to dispense the skin antiseptic composition within the container. The dispenser may include an applicator with a hydrophilic foam.
摘要:
The invention relates to a solid crop protection formulation comprising a) at least one crop protection agent selected from the group consisting of herbicides, pesticides and fungicides, with the proviso that cinidon-ethyl is not included; b) at least one random radical copolymer comprising as polymerized units at least one hydrophilic and at least one hydrophobic monomer; and c) optionally further additives, wherein at least 50% of the dispersed particles of the at least one crop protection agent in said solid crop protection formulation are in an X-ray amorphous state. Additionally, the invention relates to processes for preparing said formulations and the use of said formulations in agriculture.
