Abstract:
A personal cleansing composition, comprising:i) from about 0.001% to 49.9% by weight of a conventional personal cleansing additive; ii) from about 0.1% to 49.999% by weight of a surfactant system comprising a branched surfactant mixture, said branched surfactant mixture comprising mid-chain branched and linear surfactant compounds, said linear compounds comprising 25% or less by weight of the branched surfactant mixture; wherein the mid-chain branched surfactant compounds are of the formula: Abâˆ’B â€ƒwherein: Ab is a hydrophobic moiety having from about 10 to about 18 total carbons divided between a longest chain and at least one short chain, the longest chain being in the range of from about 9 to about 17 carbon atoms, there being one or more C1-C3 alkyl moieties branching from the longest chain, provided that at least one of the branching alkyl moieties is attached directly to a carbon of the longest linear carbon chain at a position within the range of position 3 carbon, counting from carbon #1 which is attached to theâ€”B moiety, to position &ohgr;â€”2 carbon, wherein &ohgr; is the terminal carbon; B is a hydrophilic moiety selected from the group consisting of OSO3M, (EO/PO)mOH, (EO/PO)mOSO3M and mixtures thereof, wherein EO/PO are alkoxy moieties selected from the group consisting of ethoxy, propoxy, and mixtures thereof, wherein m is at least about 1 to about 30 and M is hydrogen or a salt forming cation; provided that the average total number of carbon atoms in the Ab moiety in the branched surfactant mixture is within the range of about 12 to 14.5; and (iii) from about 50% to about 99.899% , by weight of an aqueous liquid carrier.
