摘要:
The present invention relates to a fluorescent whitening agent comprising a mixture of two symmetrically and one asymmetrically substituted triazinylaminostilbene disulphonic acids, novel asymmetrically substituted derivatives, a process for their preparations and use of the mixture for whitening synthetic or natural organic materials, especially paper and for the fluorescent whitening and improvement of sun protection factors of textile materials.
摘要:
A process for improving the sun protection factor (SPF) of cellulosic fibre materials and blends thereof, which comprises contacting said materials with at least one compound of the formula (1) in which M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; R1 and R1′ independently of each other are hydrogen, hydroxy, optionally substituted alkyl, 4-morpholinyl, —NH—R3, —N(R3)2 or —O—R3, wherein R3is optionally substituted alkyl or optionally substituted aryl, R2 is a group of formula (2) wherein X is —O— or —NH— and R4 is C1-C4-alkyl which carries at least one hydrophilic substituent and R2′ has the meaning of R1 or R2.
摘要:
Disclosed are dispersions of fluorescent whitening agents which are suitable for the fluorescent whitening of coating compositions for coating paper or of fibre dispersions (paper pulps) in paper production.
摘要:
Stable formulations of fluorescent whitening agents are described. These contain a) 2 to 20% by weight of a fluorescent whitening agent of formula (1) in which R1 is hydrogen, C1-C5-alkyl, C1-C5-alkoxy or halogen and M is hydrogen, an alkali metal, ammonium or magnesium, b) 4 to 30% by weight of an unmodified or modified polyvinyl alcohol, c) 55 to 94% by weight of water and d) 0 to 20% weight of further additives, polyethylene glycol being excluded. A process for the preparation of the formulations and their use for whitening paper materials is also described.
摘要:
The invention discloses multifunctional textile auxiliary formulations comprising (a) 10 to 60% by weight of one or more than one nonionic surfactant of formula (1), (b) 10 to 60% by weight of the reaction product of one or more than one nonionic surfactant of formula (2) and of an ethylenically unsaturated sulfonic or carboxylic acid or an anhydride thereof, (c) 4 to 20% by weight of a hydrotropic agent, (d) 0 to 20% by weight of a nonionic surfactant of formula (3), (e) 0 to 8% by weight of a magnesium salt of an organic carboxylic acid, (f) 0 to 30% by weight of a chelating agent or sequestrant, (g) 0 to 10% by weight of a diol or polyol, and (h) 0 to 60% of water, with the proviso that the textile auxiliary formulations must contain one of components (e) to (g). The novel textile auxiliary formulations are distinguished by their low foaming properties, their storage-stability, their peroxide-stabilizing properties, their good emulsifiability and their good rewettability. In addition, the formulations are readily biogradable.

The present invention provides a microstructured cosmetic composition comprising:A) a cosmetically acceptable oil phase which is dispersed in;B) an aqueous phase comprising 0.05 to 3.0, preferably 0.2 to 1.0% by weight, based on the weight of the total composition, of a .beta.-1,3-glucan having a mean molecular weight within the range of from 1.times.10.sup.6 to 12.times.10.sup.6, preferably from 2.times.10.sup.6 to 10.times.10.sup.6 ;the oil phase A) in the microstructured cosmetic composition having a mean particle size within the range of from 0.05 to 1000 microns.
摘要:
The present invention relates to storage stable aqueous dye dispersions, comprising (a) 2.0 to 30.0% by weight, based on the sum of (a), (b) and (c), of a dye of the formula (3) in which KK is a residue of a coupling component; (b) 0.1 to 20.0 % by weight, based on the sum of (a), (b) and (c), of at least one additive selected from the group consisting of wetting agents, dispersing agents, rheology modifiers, and preservatives; and (c) 50.0 to 97.9% by weight, based on the sum of (a), (b) and (c), of water. The invention moreover relates to a process for their preparation and the use thereof for the dyeing, in particular of paper.
摘要:
A detergent additive is described, which comprises at least one swellable layered silicate, an antimicrobial active substance and a surfactant and, optionally, an alkali salt. This detergent additive is distinguished in that it protects the antimicrobial active substance from oxidation by the bleaches which are usually present in detergents and in that said active substance is only released during the washing process.
摘要:
The present invention relates to an aqueous direct dye formulation, comprising (a) 5 to 25% by weight of a dye composition comprising (a1) 50-99% by weight of one or more dyes obtainable by reduction or thermal treatment of Direct Yellow 11, and (a2) 1-50% by weight of a blue, black and/or red direct dye, (all based on the dye composition); (b) up to 0.9% by weight of a saturated, cyclic or acyclic water-soluble amine comprising a primary, secondary or tertiary amino group and at least one further functional group selected from primary, secondary and tertiary amino groups, OH groups and ether groups; and (c) up to 0.9% by weight of urea; and (d) water, wherein the percentages for (a), (b), and (c) relate to the total weight of the aqueous direct dye formulation. The invention moreover relates to a process for their preparation and the use thereof for the dyeing, in particular of paper, as well as paper which has been dyed with this aqueous direct dye formulation.
