Abstract: The invention concerns polyalkoxylated terpenic compounds of formula Z-X—W—[CH(R5)—CH(R6)—O]q-A in which Z is a bicycloheptenyl or bicycloheptyl radical, preferably substituted by methy radicals; X is preferably a —CH2—CH2—O or O—CH2—CH2—O— radical; W is a polysequence, preferably polyoxypropylene and polyoxyethylene; [CH(R5)—CH(R6)—O]q is a sequence different from a polyoxyethylene sequence, preferably polyoxypropylene; A is H, a functional or hydrocarbon group. They can be prepared by successively polyalcoxylating the reagent Z-XH. They can be used as antifoaming agents in foaming aqueous media, in particular in degreasing aqueous media in alkaline medium of sheet metals, as well as detergent aqueous media in household washing or industrial and institutional washing.

Abstract: A detergent composition containing alkali-metal silicate with an average molar ratio of SiO2/M2O of 1-4.2, preferably 2.5-4.2, wherein M is an alkali metal, the composition being non-corrosive to glass, crystal, porcelain and decorative prints thereon upon repeated washing. The composition being such that when disposed in a washing medium at a normal working concentration, a protonated silicic monomer Si(OH)4 is produced in a concentration of at least 2.5×10−3 mol/liter of the washing medium.
