A removal composition and process for cleaning post-chemical mechanical polishing (CMP) contaminants and particles from a microelectronic device having said particles and contaminants thereon. The removal compositions include at least one at least one organic additive; at least one metal chelating agent; and at least one polyelectrolyte. The composition achieves highly efficacious removal of the particles and CMP contaminant material from the surface of the microelectronic device without compromising the low-k dielectric, silicon nitride, and metal containing layers such as tungsten-containing layers.

Provided herein are polysaccharide derivatives substituted (a) at a degree of substitution (DS1) of at least 0.05 by a fluorescent group (FG) having a mono or polycyclic ring system including at least one heteroatom selected from N, O and S and conjugated double bonds, and having an absorption band in the UV region of light and an emission band in the visible region of light, and bonded via a first linker to any one of the native functional groups of the polysaccharide repeating units; and (b) at a degree of substitution (DS2) of at least 0.05 by a charged group (CG) bonded via a second linker to any one of the native functional groups of the polysaccharide repeating units.

The present invention relates to a process for reducing malodors on fabrics using a detergent composition containing an antioxidant and use of said antioxidant and said process.

The present invention relates primarily to fragrance substance mixtures, preferably perfume oils, comprising or consisting of (a) 8,8-dimethyl-6,10-dioxaspiro[4,5]decane, i.e. a compound of formula (I) as described herein, and additionally (b) one or more fragrance substance(s) selected from the group consisting of esters, lactones, oximes and sulphur compounds with a molar mass of 240 g/mol or less and/or (c) one or more fragrance substance(s) selected from the group consisting of acetals, ketones and ethers with a molar mass in the range of 126-240 g/mol. The invention further relates to methods for the production of fragrance substance mixtures according to the invention, methods for enhancing the natural freshness and/or radiance and/or for masking or reducing sulphurous, artificial and/or metallic notes of one or more fragrance substances different from the compound of formula (I), perfumed products containing a fragrance substance mixture according to the invention, methods for producing perfumed products according to the invention and the use of the compound of formula (I) for enhancing the natural freshness and/or radiance and/or for masking and/or reducing sulphurous, artificial and/or metallic notes of one or more fragrance substances different from the compound of formula (I).

Provided is a photoactivating device (100) for deployment in a washing machine for activating one or more photoactive components in a laundry treatment composition, comprising: a light source (160) configured for emission of light for activation of the one or more photoactive components; a controller (180), and a switch and/or a motion sensing unit (170), wherein the controller (180) is configured to control the light source (160) responsive to the switch and/or signals received from the motion sensing unit (170).

A non-oxidizing, buffered disinfectant concentrate is provided to be included in a solution used to disinfect a membrane. The solution applied to the membrane is configured to have a pH that is compatible with the membrane. The disinfectant concentrate includes an aqueous solvent; a hydrotrope; a strong acid surface cleanser; a biocidal active, preferably, at least two biocidal actives; a buffer agent; and, optionally, an anionic surfactant. The biodical active may be selected to function both as a biocide and as a weak acid/buffer combination. A disinfectant solution applied to the membrane includes from about 0.1 wt % to about 3.5 wt % of this disinfectant concentrate.

The invention is directed to the field of pro-fragrances used in detergents and cleaning agents, cosmetic agents and air fresheners, for example.
