Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A method of softening textiles without yellowing which comprises contacting textile materials in the aqueous rinse cycle of a laundering operation with from about 0.05 percent to about 1 percent by weight of a borohydride containing composition consisting essentially of a quaternary borohydride selected from the group consisting of: A. long chain monoalkyltriloweralkyl ammonium borohydride wherein said long chain alkyl group has from 16 to 24 carbon atoms and said lower alkyl groups have from one to six carbon atoms; B. dilongchain alkyl dilower alkyl ammonium borohydrides said long chain alkyls have from 12 to 24 carbon atoms and said lower alkyls have from one to six carbon atoms; C. ethoxylated derivatives of quaternary compounds represented by the formula
Claim 2
Independent Claim
119 words
A method of softening textiles without yellowing which comprises contacting textile materials in the aqueous rinse cycle of a laundering operation with from about 0.05 percent to about 1 percent by weight of a borohydride containing composition consisting essentially of a quaternary borohydride selected from the group consisting of: A. long chain monoalkyltriloweralkyl ammonium borohydride wherein said long chain alkyl group has from 16 to 24 carbon atoms and said lower alkyl groups have from one to six carbon atoms; B. dilongchain alkyl dilower alkyl ammonium borohydrides said long chain alkyls have from 12 to 24 carbon atoms and said lower alkyls have from one to six carbon atoms; C. ethoxylated derivatives of quaternary compounds represented by the formula
Claim 3
Independent Claim
76 words
A method of softening textiles without yellowing which comprises treating materials in the aqueous rinse cycle of a laundering operation with from about 0.05 percent to about 1 percent by weight of a borohydride containing composition consisting essentially of a quaternary compound and an alkali metal borohydride in a mole ratio of from 1:1 to 1:100 and wherein said quaternary compound is selected from the group consisting of A. quaternary ammonium compounds represented by the formula
Claim 4
Independent Claim
76 words
A method of softening textiles without yellowing which comprises treating materials in the aqueous rinse cycle of a laundering operation with from about 0.05 percent to about 1 percent by weight of a borohydride containing composition consisting essentially of a quaternary compound and an alkali metal borohydride in a mole ratio of from 1:1 to 1:100 and wherein said quaternary compound is selected from the group consisting of A. quaternary ammonium compounds represented by the formula
Claim 5
Dependent Claim
18 words
The method according to claim 3 wherein said borohydride composition comprises sodium borohydride and dimethyl distearyl ammonium chloride.
Claim 6
Dependent Claim
20 words
The method of claim 3 wherein said borohydride is present relative to the quaternary compound in a 1:1 mol ratio.
