The present invention relates to a process for depositing a metal layer on a substrate by contacting the substrate with a metal plating bath comprising a metal ion source and a suppressor, and applying a current density to the substrate, where the suppressor is a polycarboxylate ether as described below. The invention further relates to a metal plating bath comprising a metal ion source and the suppressor which is a polycarboxylate ether; and to a use of the polycarboxylate ether in a metal plating bath for depositing a metal layer on a substrate.

The present invention relates to amphiphilic star-like polyether. The core molecule is an aliphatic hyperbranched polyether polyol, which is further alkoxylated, first with ethylene oxide or combinations of ethylene oxide and C-Calkylene oxide, preferably propylene oxide, and/or glycidol, and then with a C-Calkylene oxide, preferably propylene oxide, or combination of ethylene oxide and propylene oxide, then optionally anionically modified. The resulting amphiphilic star-like polyether thus has an inner core based on an aliphatic hyperbranched polyether polyol, an inner shell predominantly containing polyethylene oxide units, the inner shell comprising at least 3 ethylene oxide units and an outer shell predominantly containing polypropylene oxide units, the outer shell comprising at least 3 propylene oxide units. They optionally contain anionic groups instead of hydroxyl groups on the periphery of the macromolecule. The invention further relates to their use as additive in laundry formulations and to their manufacturing process.

The present invention relates to the use of (oxidized) thioethers of polyalkylene oxides in washing and cleaning compositions, especially in dishwashing compositions, and to washing and cleaning compositions, especially dishwashing compositions, which comprise (oxidized) thioethers of alcohol alkoxylates. These (oxidized) thioethers are especially suitable as surfactants with rinse aid function (rinse aid surfactants). 'Oxidized' relates to the sulfur atom in the thioether, which may be present in oxidized form as sulfoxide (SO) or sulfonyl (SO). The invention also relates to particular oxidized thioethers of polyalkylene oxides.

Compositions and methods of synthesis of anionic surfactants by alkoxylation of a Guerbet alcohol (GA) having 12 to 36 carbon atoms using butylene oxide, and optionally propylene oxide and/or ethylene oxide followed by the incorporation of a terminal anionic group are described herein. The GA of the present invention is made by a facile and inexpensive method that involves high temperature base catalyzed dimerization of alcohols with 6 to 18 carbon atoms. The large hydrophobe ether surfactants of the present invention find uses in enhanced oil recovery (EOR) applications where it is used for solubilization and mobilization of oil and for environmental cleanup. Further, the hydrophobe alkoxylated GA without anionic terminal group can be used as an ultra-high molecular weight non-ionic surfactant.
