Abstract
Abstract This invention relates to a detergent composition comprising: (a) from about 40 to 60% by weight of compounds of formula R.sup.1 --O--(CH.sub.2 CH.sub.2 O).sub.n --H (I) wherein R 1 represents a saturated or unsaturated aliphatic radical of a fatty alcohol having from about 6 to 18 carbon atoms, and n is an integer of from 4 to 15; and (b) from about 60 to 40% by weight of compounds of formula ##STR1## wherein R 2 and R 3 each independently represent an alkyl radical having from about 1 to 17 carbon atoms, the total number of carbon atoms in R 2 and R 3 being from about 8 to 18, and p and q each independently represent a number from 0 to 15, the sum of p and q being from about 4 to 15.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
A detergent composition consisting essentially of (a) from about 40 to 60% by weight of compounds of formula R.sup.1 --O--(CH.sub.2 CH.sub.2 O).sub.n --H (I) wherein R 1 represents a saturated or unsaturated radical of a fatty alcohol having from about 6 to 18 carbon atoms, and n is an integer of from 4 to 15; and (b) from about 60 to 40% by weight of compounds of formula ##STR3## wherein R 2 and R 3 each independently represent an alkyl radical having from about 1 to 17 carbon atoms, the total number of carbon atoms in R 2 and R 3 being from about 8 to 18, and p and q each independently represent a number from 0 to 15, the sum of p plus q being from about 4 to 15.
Claim 2
Dependent Claim
132 words
A detergent composition consisting essentially of (a) from about 40 to 60% by weight of compounds of formula R.sup.1 --O--(CH.sub.2 CH.sub.2 O).sub.n --H (I) wherein R 1 represents a saturated or unsaturated radical of a fatty alcohol having from about 6 to 18 carbon atoms, and n is an integer of from 4 to 15; and (b) from about 60 to 40% by weight of compounds of formula ##STR3## wherein R 2 and R 3 each independently represent an alkyl radical having from about 1 to 17 carbon atoms, the total number of carbon atoms in R 2 and R 3 being from about 8 to 18, and p and q each independently represent a number from 0 to 15, the sum of p plus q being from about 4 to 15.
Claim 3
Dependent Claim
