Shaped washing agents based on synthetic detergents and/or soaps containing from 1 to 10% by weight, based on the total composition of a compound supplying resistance to cracking selected from the group consisting of branched-chain alkanols having from 12 to 20 carbon atoms and di-octyl adipate having up to 50% of n-octyl groups.
摘要:
The invention relates to an improvement of the known continuous process for the separation of mixtures of fatty alcohols of different melting points, in which the starting mixture by treating with an aqueous wetting agent solution is converted to a dispersion of liquid fatty substances and solid fatty substance particles, the formed dispersion is separated into two phases of different specific gravities, the lighter phase consists substantially of the liquid fatty fraction and the heavier phase of a dispersion of the solid fatty particles in the aqueous wetting agent solution. After separation of this suspension the wetting agent solution is returned to the process. The improvement consists in withdrawing a part of the recycling wetting agent solution from said dispersion of fatty particles in the aqueous wetting agent solution by separation of some or all the aqueous solution from the solid fatty particles, the solid fatty particles with the remaining aqueous phase and adhering wetting agent are melted in the presence of an aqueous phase and the molten fatty fraction containing little wetting agent, is separated from the aqueous phase enriched with wetting agent which is recycled and the amount of wetting agent solution withdrawn is replaced with fresh wetting agent solution.
摘要:
A process for producing carboxylic acids having at least 5 carbon atoms in which a mixture of vicinal diols having at least 6 carbon atoms with 0.01 to 0.5 mol per cent of heavy metal compound catalyst is continuously introduced, in an amount and at a rate such that the reaction is maintained, into an initiated mixture of vicinal diols having at least 6 carbon atoms, carboxylic acids formed therefrom and a heavy metal compound catalyst, which is contacted with an oxygen containing stream of gas, the reaction being carried out at temperatures between 40.degree. C and 200.degree. C, preferably 60.degree. C to 140.degree. C, and the oxidation mixture is continuously drawn off.
摘要:
A process of suppressing body odors comprising applying a substantially anhydrous cosmetic preparation for supressing body odor containing as a deodorant an ester of an aliphatic mono- or di-hydroxycarboxylic acid or an aliphatic mono- or di-hydroxy-dicarboxylic acid having from 2 to 4 carbon atoms with an aliphatic alcohol having from 1 to 6 carbon atoms, or an alicyclic alcohol having 5 to 6 carbon atoms.
摘要:
Organic disulfonamides are accelerators for aerostable, anaerobically-setting adhesive compositions. They provide rapid setting of the adhesive with formation of bonds of good strength, and have little adverse effect upon the storage stability of the compositions when access of molecular oxygen is permitted.
摘要:
Therapeutic methods employing cyclic aminophosphonic acids having the formula ##EQU1## wherein R is a member selected from the group consisting of hydrogen and alkyl having from 1 to 6 carbon atoms and n is an integer from 1 to 4; as well as their water-soluble salts. The cyclic aminophosphonic acids are excellent sequestering agents especially for alkaline earth metal ions, useful in cosmetic preparations such as toothpastes and mouthwashes where they prevent formation of tartar and plaque and in therapy in the treatment of diseases related to the abnormal deposition or dissolution of difficulty soluble calcium salts in the animal body.

摘要:
A storage-stable, readily-soluble detergent additive comprising particles, at least 70% of which have a diameter within the range of 0.1 mm to 1 mm consisting of from 1% to 75% by weight of at least one active material enhancing the washing, bleaching or biocidal effects of a detergent, substantially surrounded by and embedded in from 25% to 99% by weight of an enveloping material consisting of a mixture ofA. from 20% to 90% by weight of said mixture of at least one compound having a melting point above 30.degree.C, selected from the group consisting of fatty acids and fatty alcohols,B. from 0 to 50% by weight of said mixture of at least one water-soluble compound selected from the group consisting of poly-oxy-lower alkylene glycols, non-ionic surface-active compounds and anionic surface-active compounds, andC. from 1% to 40% by weight of said mixture of at least one water-insoluble but water-swellable compound selected from the group consisting of salts of acrylic acid copolymers and methacrylic acid copolymers. The invention also relates to the method of producing the particles and the enveloping material. The particles are obtained by spraying a fluid mixture of the components through a nozzle or by a spray disc, and cooling. The stabilized particles of active materials can be incorporated with percompounds and other washing composition components.
