    摘要: The invention relates to a method for the production of tertiary amine oxides with and prevented and/or reduced nitrosamine formation and/or reduced nitrite formation, comprising the steps of: during or after the production of the aforementioned tertiary amine oxide, adding a mixture comprising a poiyamino methylene phosphonate of formula (I) wherein n=2-1500, M is hydrogen or a cation selected from alkali metals, alkaline earth metals and ammonium, and the R groups are the same or different from one another with at least one R group different from CH2PO3M2 and selected from the following classes: 1) CH2PO3M2 2) CH2R' R'=CH2OH; CHOHCH3; CHOHCH2CI or CHOHCH2OH; 3) (CH2)nSO3M wherein n=3+4 4) CH2CH2R" wherein R"=CONH2, CHO, COOR1, COOX or CN; where R1=CH3+CH2H5; wherein X is hydrogen or an alkali metal or ammonium cation. The invention also relates to tertiary amine oxide composition with improved nitrosamine contents and/or nitrite contents; as well as use of the aforementioned polyamino methylene phosphonates as nitrosamine inhibitor and/or as nitrite inhibitor.

    摘要: The present invention relates to textile treating compositions which are especially useful for treating textiles in the rinse cycle of a textile laundering operation to provide improved fabric softening and conditioning benefits. The textile treatment compositions comprise a substantially water-insoluble cationic fabric softening agent in combination with a substantially saturated lipid component containing one or more phosphoglycerides. The present invention further relates to a method for softening and conditioning textiles by treating the textiles, preferably during the rinse cycle of a textile laundering operation, with a combination of the softening agent and substantially saturated lipid component.

    摘要: Detergent compositions are characterised in that they contain, on a dry weight basis, from 1 to 40% of a water-insoluble aluminosilicate and from 0.5 to 5% of a aminopoly(methylenephosphonate) component which is a mixture of an ethylenediamine derivative of the formula
    and a diethylenetriamine derivative of the formula
    where in each formula at least three R's represent -CH 2 PO 3 M 2 , with M representing hydrogen or an alkali metal and the remaining R's represent hydrogen, -CH 3 or -CH 2 PO 3 M 2 , in which mixture the ratio by weight of the ethylenediamine derivative to the diethylenetriamine derivative is from 3:1 to 1:5, and the combined weight of the aluminosilicate material and the aminopoly(methylenephosphonate) component is at least 5% of the dry weight of the composition.
