    Abstract: Compositions comprising a neutral surfactant or a reaction product thereof and a reaction product of a saccharide polymer and a fatty acid may be obtained in the presence of water and a hydroxide base (optionally in the presence of the neutral surfactant), the saccharide polymer comprising a dextran, a dextrin compound, or any combination thereof. The reaction product of the saccharide polymer and the fatty acid may be present at a concentration effective to lower surface tension of the neutral surfactant. Depending on the fatty acid identity, among other factors, the compositions may promote emulsification or de-emulsification. In addition, the compositions may promote foam formation under appropriate conditions. Treatment fluids comprising the compositions, including foamed treatment fluids, may be introduced into a subterranean formation to perform a treatment operation in which fluid emulsification or de-emulsification may occur. The reaction products may be incorporated in soaps and other personal care products.

    Abstract: An aqueous cleaning composition comprising: (a) from 0.01 to 0.5% by weight of the composition of a grease loosening system comprising: i) 50% or more by weight of the system of a low emulsifying surfactant wherein the low emulsifying surfactant is a nonionic ethoxylate having an HLB value of from about 13 to about 20; and ii) 50% or less by weight of the system of a high emulsifying material wherein the high emulsifying material is selected from the group consisting of nonionic surfactant having an HLB value of less than 13, a surfactant other than nonionic surfactants; antimicrobial quats and mixtures thereof; (b) a shine polymer comprising at least one monomer comprising a substantially planar 5-7 membered ring, said monomer preferably being selected from the group consisting of vinylpyrrolidone, vinylimidazoline, maleimide, styrene sulfonate and vinylcaprolactam; and (c) optionally a non-quaternary ammonium compound antimicrobial agent.
