  • Patent number: 7534760
    Abstract: The present invention relates to a clear and stable, highly alkaline composition with controlled foaming, containing a high amount of surface active nonionic alkylene oxide adduct and a hexyl glycoside as a hydrotrope. This composition has a very good wetting and cleaning ability and can be used for cleaning of hard surfaces, in a mercerization process and for a cleaning, desizing or scouring process of fibres and fabrics.

  • Publication number: 20030181347
    Abstract: The present invention relates to a one-phase microemulsion that contains an emulsifier system containing a branched alkyl glycoside of the formula (I): R1OGn, where R1 is a branched alkyl group containing 8-16 carbon atoms, G is a saccharide residue and n, the degree of polymerisation, is between 1-5, and optionally a linear alkyl glycoside with the formula (II): R2OGn, where R2 is a linear alkyl group containing 6-18 carbon atoms, G is a saccharide residue and n is between 1-5, a water insoluble oil component, water and, if needed, minor amounts of a cosurfactant/cosolvent. This microemulsion may be used e.g. in a cleaning process for removal of hydrophobic substances from hard surfaces or textile, and in personal care of pharmaceutical formulations.

  • Patent number: 5928993
    Abstract: An aqueous composition which contains a low-foaming alkyl glycoside of the formula (I): ROG.sub.x wherein R is a branched alkyl group having 6-12 carbon atoms, G is a monosaccharide residue, and x is a number in the range of 1-5. When combined with a low-foaming amphoteric compound and/or a low-foaming nonionic alkoxylate, the composition has proved to have a surprisingly good wetting effect. In addition to the surfactant composition, the aqueous composition may contain active substances such as pesticides, herbicides, fertilizers, cleaning surfactants, and alkaline agents.

  • Patent number: 5681949
    Abstract: In an alkyl glucoside of formula (I) R.sup.1 is an alkyl group having 2-5 carbon atoms, preferably 2-4 carbon atom; R.sup.2 is an alkyl group having 4-7 carbon atoms, preferably 5 or 6 carbon atoms, the sum of the carbon atoms in R.sup.1 and R.sup.2 being 7-11, preferably 7-9; G is a monosaccharide residue; and x is 1-4, preferably 1 or 2. The use of the alkyl glucoside as a surfactant in a cleaning composition is also disclosed.

  • Patent number: 5644041
    Abstract: The present invention generally relates to an alkyl glycoside of the formula (I): RCH.sub.2 O(G).sub.x H, wherein R is an alkyl group having a total of 8-12 carbon atoms and containing 2-4 groups of the formula --CH(CH.sub.3)-- in its carbon chain; G is a monosaccharide residue; and x is 1-4. The invention also relates to the use of the alkyl glycoside as a surfactant in the cleaning of hard surfaces. A composition containing an alkyl glycoside of formula (I), a complexing agent and a solubilizer is also disclosed.

  • Patent number: 5395543
    Abstract: A particulate alkaline detergent contains an alkaline agent and an alkali perborate hydrate and/or an alkali carbonate peroxohydrate as bleaching agent. As a result of coating at least the alkaline agent or the bleaching agent with an alkyl glycoside or an alkyl glycamide, the detergent has a low tendency to caking as well as excellent cleaning capacity. The alkyl glycoside is a C.sub.6 -C.sub.10 -alkyl glycoside having a degree of polymerization of 1-4, and the alkyl glycamide has formula (I), wherein R.sub.1 is hydrogen or an alkyl group having 1-4 carbon atoms, and R.sub.2 is an alkyl group having 6-10 carbon atoms. A bleaching agent and an alkaline agent coated with the alkyl glycoside and/or the alkyl glycamide are also disclosed.
