摘要:
A freshening composition having a malodor control component, about 1% to about 5% of low molecular weight monohydric alcohols, and an aqueous carrier are provided. The composition is essentially free of any material that would soil or stain fabric. The composition may be delivered to fabrics and/or air. The malodor control component may include an effective amount of volatile aldehydes and/or an acid catalyst.

A film formed from a water-soluble polymer matrix within which is contained at least one fragrance is provided. The film is water-sensitive (e.g., water-soluble, water-dispersible, etc.) so that upon contact with a sufficient amount of water, the polymer matrix loses its integrity over time to increasingly expose the fragrance to the ambient environment for releasing its odor. The ability to incorporate a fragrance into the polymer matrix is achieved in the present invention by controlling a variety of aspects of the film construction, including the nature of the fragrance, the nature of the water-soluble polymer, the manner in which the polymer matrix and fragrance are melt processed, etc. For example, the fragrance may be injected directly into the extruder and melt blended with the water-soluble polymer. In this manner, the costly and time-consuming steps of pre-encapsulation or pre-compounding of the fragrance into a masterbatch are not required. Furthermore, to obtain a balance between the ability of the fragrance to release the desired odor during use and likewise to minimize the premature exhaustion of the odor during melt processing, the fragrance is selected to have a boiling point (at atmospheric pressure) within a certain range, such as from about 125° C. to about 350° C.

A process for capturing CO2 includes contacting a CO2-containing gas with an absorption mixture optionally within a packed reactor is provided. The absorption mixture includes a liquid solution and micro-particles. The micro-particles include a support material and biocatalyst supported by the support material and are sized and provided in a concentration such that the absorption mixture flows through the packed reactor and that the micro-particles are carried with the liquid solution to promote dissolution and transformation of CO2 into bicarbonate and hydrogen ions. The absorption mixture and micro-particles may be provided in an absorption reactor so as to be pumpable. Furthermore, a process for desorbing CO2 gas from an ion-rich aqueous mixture includes providing biocatalytic micro-particles and feeding the mixture to a desorption reactor, to promote transformation of the bicarbonate and hydrogen ions into CO2 gas and water.
摘要:
Compositions and methods for controlling odors associated with animals and an animal's excrement, and environmental odors, comprising a biocidal system comprised of a primary biocide, a pH buffer agent, a surfactant, all in an aqueous based carrier.
摘要:
This invention relates to inducible release vehicle comprised of crosslinked carbohydrates or proteins and an active ingredient. The release is induced by an external stimulus, e.g. an enzyme such as amylase. Such a vehicle can particularly be used in an applications for preventing microbial decay or combating microbial infections. Other uses are for oral applications such as providing anti-caries or flavoring compounds and for pharmaceutical and/or nutraceutical applications.
摘要:
The present invention relates to the field of perfumery. More particularly, it concerns the use as perfuming ingredients of certain phenol esters of formula wherein R represents a C2-6 branched alkyl group or a C2-6 linear or branched alkenyl group or cyclopropyl containing hydrocarbon group. The present invention concerns also the compositions or articles containing such compounds.
摘要:
Oven deodorants and methods of cleaning ovens using an oven deodorant, for example, for use in self-cleaning ovens, are provided. The oven deodorant is made of clay, for example, an unfired clay, and a fragrance. The fragrance volatilizes during heating in the oven and at least partially masks any undesirable odors generated in the oven, for example, the volatilized fragrance may mask odors generated during a high-temperature self-cleaning process. The clay may be any commercially available clay, for example, a pottery clay. The fragrance may be any conventional fragrance, for example, a fragrant oil, such, as an herb-like fragrant oil.
摘要:
Disclosed herein are methods of preventing or reducing scale formation or corrosion by combining at least one scale-forming fluid comprising at least one scaling compound with at least one anti-scale material chosen from at least one scale-adsorbent agent. The methods may reduce or prevent the formation of scale on surfaces of liquid-related process equipment, such as boilers and heat exchangers.
