Abstract:
The present disclosure provides a surfactant blend containing (i) an extended chain anionic surfactant and (ii) an extended chain intermediate surfactant. The surfactant blend may be used in the preparation of cleaning compositions, or compositions for use in oil field treatment applications, water based metal working applications and polyurethane foam applications.

Claim (Index 1):
A surfactant blend comprising: (i) an extended chain anionic surfactant of the formula (I)\n R-(L) x -(O\u2014CH2-CH2) y -O\u2014SO 3 -A\u2003\u2003(I) and (ii) an extended chain intermediate surfactant of the formula (II)\n R-(L) x -(O\u2014CH2-CH2) y -OH\u2003\u2003(II) \n wherein R is a linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radical having from about 6 to about 36 carbon atoms; L is a linking group comprising a block of polypropylene oxide, or a block of polyethylene oxide, or a mixture thereof; A is selected from hydrogen, a monovalent metal cation, a divalent metal cation, ammonium cation and an organic group substituted ammonium cation; x is the average degree of alkoxylation of the linking group L ranging from about 2 to about 20; and y is the average degree of ethoxylation ranging from 0 to about 5.
