Abstract A softening agent for the posttreatment of washed laundry is disclosed, the same being adapted for addition to the rinse water either as a solid or in liquid form. The softening agent corresponds to the following formula: WHEREIN R1 is alkyl containing 10 to 22 carbon atoms, and may be interrupted by ether oxygen atoms in the vicinity of the N atom group, R2 is alkyl containing seven to 21 carbon atoms and n is either 3 or 4. Preferably the total number of the carbon atoms contained in R1 and R2 amounts to at least 23 and preferably amounts to from 27 to 35. The aforesaid softening agents can be employed per se or in combination with other conventional laundry agents such as optical brighteners, acidifiers, disincrusting agents, colorants, perfumes, antimicrobial agents, etc.
The liquid composition of claim 1 consisting essentially of 5-15 weight percent of said glycamide, wherein R1 has 12 to 20 carbon atoms, wherein R2 has 11 to 19 carbon atoms, and wherein R1+R2 have a total of 27 to 35 carbon atoms.
Claim 2
Independent Claim
100 words
A method for treating a textile-fabric article comprising laundering said article, and thereafter rinsing said article with water containing dissolved therein in the range of 0.05 to 2 grams per liter of a glycamide of the formula: wherein: R1 is (1) alkyl of 10 to 22 carbon atoms or (2) alkyl of 10 to 22 carbon atoms with an ether oxygen linkage between either the 2 and 3 or 3 and 4 carbon atoms from the nitrogen atom, R2 is alkyl of seven to 21 carbon atoms, R1+R2 have 23 to 39 carbon atoms, and n is 3 or 4.
