Isosorbide mono ether derivatives with preservation activity.

Isosorbide ether derivatives with preservation activity

The invention relates to the use of microemulsions, containing (a) at least one alkyl(oligo)glycoside, (b) at least one co-surfactant different from (a), (c) at least one water-insoluble organic oil component, (d) at least one wax, and (e) water, to produce cleaning agents, and aqueous hand dishwashing detergents, containing anionic and amphoteric surfactants and, in amounts from 0.2 to 10 wt % relative to the total weight of the hand dishwashing detergents, a microemulsion according to the description in claim, and cosmetic cleaning agents, containing A) a microemulsion according to the description in claim, B) anionic surfactants, C) cationic polymers, D) optionally additional surfactants, E) optionally cosmetic additives, and F) water.

Use of cleaning agents containing microemulsions that contain wax

The invention relates to a glycerol ether mixture which consists essentially of a) at least one Cglycerol monoalkyl ether, b) at least one Cglycerol dialkylether and optionally c) at least one Cglycerol trialkyl ether and/or d) at least one Cfatty alcohol, components a) and b) together making up at least 50% by weight of the glycerol ether mixture and the ratio by weight of component a) to component b) being in the range from 3:1 to 1:2. The invention also relates to a process for producing the glycerol ether mixture and to cosmetic compositions containing the glycerol ether mixture.

Glycerol ether mixture, cosmetic composition containing this mixture and process for its production

Disclosed is the use of water-soluble graft copolymers prepared by free-radically initiated graft polymerization of 40 to 90% by weight of component (A), selected from the group consisting of monosaccharides, oligosaccharides, polysaccharides and derivatives thereof, with 5 to 40% by weight of monomers (B), selected from the group consisting of ethylenically unsaturated C3-C10 monocarboxylic acids or the alkali or ammonium salts thereof, and 10 to 50% by weight of monomers (C), selected from the group consisting of ethylenically unsaturated N-containing monomers and/or ethylenically unsaturated monomers containing sulfo-groups, in cleaning compositions which, as well as the graft polymer, comprise at least one surfactant component, for hydrophilization and/or improvement of shine retention of hard surfaces which have been brought into contact with these cleaning compositions.

Cleaning composition comprising graft copolymers

Polymers which are suitable for use in cleaning compositions are described. The polymers are comprised of at least three different monomers. The types of monomers and ratios of the monomers in the polymers are further disclosed. Cleaning compositions containing the polymers for treating various surfaces and for use in various applications are also provided.

Polymers for use in cleaning compositions

Compositions comprising glycerol hydroxyalkyl and/or hydroxyalkenyl ethers, which correspond to the general formula: in which R, Rand R, independently, represent a hydrogen atom or a saturated or unsaturated, branched or unbranched hydroxyalkyl or hydroxyalkenyl group, or mixtures thereof, each group containing 10 to 22 carbon atoms, and the use of these, particularly, glycerol hydroxyalkyl mono- and di-ethers in detergents and as rinse agents for automatic dish detergents, particularly for multifunctional dish detergents.

Dishwashing detergent containing glycerol hydroxyalkyl ethers

The invention relates to the use of esters of hydroxycarboxylic acids with alkoxylated fatty alcohols as solubilizers for perfume oils in water. These esters not only have a strong solubilizing effect on water-insoluble perfume oils, they are also capable of dispersing calcium ions.

Use of alkoxylated hydroxycarboxylic acid esters for solubilizing perfume oils in water

A process for making an alkyl and/or alkenyl oligoglycoside preparation having a magnesium salt concentration of less than about 10 ppm involving the steps of: (a) providing an alkyl and/or alkenyl oligoglycoside preparation having an active substance content of from about 10 to 70% by weight, based on the weight of the preparation; (b) providing an acid component; (c) adjusting the pH of the alkyl and/or alkenyl oligoglycoside preparation to from about 4 to 9.5 by combining the acid component with the alkyl and/or alkenyl oligoglycoside preparation to form a pH-modified alkyl and/or alkenyl oligoglycoside preparation; (d) providing a column charged with an ion exchange resin; and (e) purifying the pH-modified alkyl and/or alkenyl oligoglycoside preparation by passing it through the column of step (d) at a viscosity of from about 20 to 6,000 mPas, and at a temperature of from about 20 to 90&#xb0; C. to form the alkyl and/or alkenyl oligoglycoside preparation having a magnesium salt concentration of less than about 10 ppm.
