Abstract
Abstract A method for inhibiting dye-staining during laundering of textile articles with compositions which consist of a soap or detergent composition comprising as dye-staining inhibitor A. a minor proportion of an organic compound containing at least one basic nitrogen atom to which is bound at least one residue containing a polyglycol ether chain, the molecule of this compound containing at least 3 groups having the formula ##STR1## and containing at least 4 carbon atoms not attached to these groups, and/or B. a minor proportion of a reaction product of an aliphatic tertiary polyamine with an aliphatic dihalide.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
133 words
A method for inhibiting the dye-staining of textiles during washing comprising contacting the textile articles during the washing process with (a) a reaction product of at least three molecular proportions of an α,β-alkylene oxide with one molecular proportion of an organic compound which contains at least one basic primary or secondary amino group or a basic tertiary amino group as well as an alcoholic hydroxyl group or is an acid salt or a quaternary ammonium salt of such a reaction product, and (b) of a reaction product of an aliphatic tertiary polyamide with an aliphatic dihalide or (b) of a reaction product of an aliphatic tertiary polyamine with an aliphatic dihalide. Wherein the proportions of (a) and (b) are each 0.25 grams per liter to 2 grams per liter of the wash water.
Claim 2
Independent Claim
133 words
A method for inhibiting the dye-staining of textiles during washing comprising contacting the textile articles during the washing process with (a) a reaction product of at least three molecular proportions of an α,β-alkylene oxide with one molecular proportion of an organic compound which contains at least one basic primary or secondary amino group or a basic tertiary amino group as well as an alcoholic hydroxyl group or is an acid salt or a quaternary ammonium salt of such a reaction product, and (b) of a reaction product of an aliphatic tertiary polyamide with an aliphatic dihalide or (b) of a reaction product of an aliphatic tertiary polyamine with an aliphatic dihalide. Wherein the proportions of (a) and (b) are each 0.25 grams per liter to 2 grams per liter of the wash water.
