Abstract: Disclosed herein are diketopiperazine microparticles having a specific surface area of less than about 67 m2/g. The diketopiperazine microparticle can be fumaryl diketopiperazine and can comprise a drug such as insulin.

Abstract: This invention relates to a novel non-aqueous liquid oxygen bleach composition prepared by dispersing solid peroxygen compound in the liquid in which the content of an anhydrous non-polar organic solvent and a non-ionic and anionic surfactant is controlled. The composition is formed in a high viscous paste or a gel-type suspension and can be used as a multi-purpose composition, for example, the bleach and stain remover of clothes and the cleanser of bathroom and kitchen since they have a chemical/physical stability of no loss of available oxygen, an excellent bleaching and cleaning ability due to their alkaline pH range, no change of viscosity or no phase separation during the storage and so on.

Abstract: A process for preparation of co-granules including one or more bleach activators and one or more bleach agent compounds is described. The bleach component is mixed and coated with a binder selected from the group of fatty acids, fatty acid polyol esters, polyglycols and fatty alcohol oxalkylates. One or more bleach activators is added to this mixture followed by granulation or agglomeration in a mixer, resulting in a bleach co-granule composition including the bleach activator and peroxide components.

Abstract: A cleaning, disinfection, and indicator agent comprising a water-soluble permanganate, particularly for mixture with an agent for ensuring an alkaline milieu having a pH value of at least 11, which, in addition to the water-soluble permanganate, contains a further oxidizing agent, whose oxidation potential is above that of manganese VII to manganese VI, pH buffer substances, preferably primary and/or secondary alkali carbonates such as sodium carbonate and/or sodium hydrogen carbonate, as well as oxidation-resistant polyphosphates. Furthermore, methods for cleaning, disinfecting, and monitoring the cleanliness of commercial and industrial plants or plant components and the use of an agent according to the present invention as an indicator solution for ascertaining the cleanliness of commercial and industrial plants or plant components by ascertaining the intensity of the light emitted in the violet wavelength range by the solution are described.

Abstract: The present invention provides a lens care kit for disinfecting and cleaning contact lenses. The lens care kit of the invention allows customers to visually identify when their lenses are disinfected, clean, and ready to wear. The invention is relied on color change to indicate the readiness of disinfection and cleaning of contact lenses.

Abstract: A laundry detergent composition with a limited number of natural ingredients containing a hydrogen peroxide source, sodium carbonate and a surfactant selected from a fatty alcohol sulfate, alkyl polyglucoside and a lauryl sarcosinate. The laundry composition optionally has a fragrance, colored speckles, builder and enzymes. The laundry detergent composition can be used to clean tough stains on fabrics and cleans as well or better than commercial compositions containing synthetically derived cleaning agents.

Abstract: The present invention relates to the use as perfuming ingredient of a compound of formula wherein R represents a hydrogen atom or a methyl or ethyl group, and R1 represents (i) a (Me)(R2)C?C(R3) group, R2 representing a hydrogen atom or a methyl group and R3 representing a methyl or ethyl group, or (ii) a phenyl group optionally substituted by one or two methyl groups; as well as to the compositions or articles associated with these compounds.

Abstract: Stable oxidizing compositions and a method of preparing such compositions are presented. The compositions include a peroxygen, for example, a potassium monopersulfate or, percarbonate particle suspended in an alcoholic gel. The alcohol content in the gel is such that the peroxygen particle is prevented from coming into contact with water during storage, thereby helping maintain a high available oxygen level. When the alcoholic gel is mixed with water, it becomes less viscous and exposes the peroxygen particle to the water. The peroxygen is ready for use when it dissolves in the water.

Abstract: A disinfecting deodorant comprising an aqueous solution containing 10 to 1000 ppm of a chlorine-containing oxidizing agent and having a pH adjusted to 8 to 13 with an inorganic salt or an organic salt, a disinfecting and deodorizing method comprising applying the disinfecting deodorant to air or an object, and a disinfecting and deodorizing tool comprising a container having the disinfecting deodorant, the container being equipped with a prescribed atomizing means designed to atomize the disinfecting deodorant into a mist comprising droplets having a particle size of 10 ?m or smaller in a proportion of 2% or less in number in a particle frequency distribution.

Abstract: Compositions and methods of disinfecting and cleaning medical articles are disclosed. Disinfecting contact lenses by generating of peracetic acid in situ, while simultaneously cleaning with a proteolytic enzyme, is a preferred embodiment. Tablets for simple consumer use including disinfecting and cleaning means, and delayed release neutralizing means, are also disclosed.
