摘要:
The aliphatic primary alcohols are reacted with a glycose, more especially glucose, in the presence of an acidic catalyst in certain process steps so that particularly light-colored and alkali-stable alkyl glucosides are obtained after a subsequent, compulsory bleaching step, which represents an improvement over known direct synthesis processes. The process may be carried out both on a laboratory scale and also on an industrial production scale.
摘要:
A process for the production of surface-active alkyl glycosides which is carried out by the transacetalization method with butanol, leads to a new alkyl glycoside as end product which is characterized by high color-stability in alkaline medium; besides a high proportion of alkyl monoglycoside, the product also contains polyglycoside on polyglycose and butyl glucoside.
摘要:
Surface active alkylglucosides are prepared in a 2-step process from starch or starch degradation products such as polyglucose or glucose syrup, the first step consisting of reaction with a short chained alcohol, particularly butanol, while the second step comprises transacetalization with the longer chained C.sub.8-22, more particularly C.sub.12-18, alcohol, with fatty alcohols of natural origin preferably being used.

Detergent mixtures with improved processability contain 70 to 95% by weight of fatty acid isethionate salts, 5 to 30% by weight of fatty alcohols, 0 to 15% by weight of fatty acids, 0 to 15% by weight of alkyl and/or alkenyl oligoglycosides and 0 to 15% by weight of fatty acid N-alkyl polyhydroxyalkylamides, providing that the quantities add up to 100% by weight. The optionally self-emulsifying mixtures are suitable, for example, for the production of solid or liquid soaps.
摘要:
Powder-form preparations of surface-active alkyl glycosides contain 5 to 65% by weight of a surface-active alkyl glycoside and 35 to 95% by weight of an inert inorganic support. They are produced by mixing the crude product obtained in the industrial production of the alkyl glycosides with water and an inorganic particulate support, for example silica, chalk or sodium chloride, and drying the resulting mixture. Preferred powder-form preparations contain 20 to 50% by weight of the alkyl glycoside and 50 to 80% by weight of an inert inorganic support.
摘要:
Aqueous homogeneous preparations containing 0.0025 to 0.1% by weight antimicrobial biguanide compounds, 0.005 to 0.2% by weight of an alkyl glycoside, 0.01 to 0.3% by weight of a water-insoluble aromatic oil, 0.01 to 0.3% by weight of a solubilizer from the group consisting of ethoxylated fatty acid glycerides, ethoxylated fatty acid sorbitan partial esters or fatty acid partial esters of glycerol or sorbitan ethoxylates show high activity despite the low concentration of antimicrobial biguanide compounds. The clear solubility is obtained without ethanol or with only very small contents of up to 15% by weight of ethanol. The preparations are particularly suitable as mouthwashes.
摘要:
Provided are the application of waxes, preferably in the form of aqueous wax dispersions comprising a dispersing agent (a) and a wax component (b) and optionally additional auxiliary and additive materials (c). The mechanical properties of textile fibers treated with these aqueous wax dispersion compositions are improved. In particular, the tear resistance of the textile fibers are improved.
