Abstract:
The present invention relates to alkoxylated esteramines of Formula (I) and salts thereof. Esteramines according to the present invention may be used in cleaning composition, for example in liquid laundry detergents. They lead to improved cleaning performance of said compositions, for example when used in cold water washing conditions. They surprisingly boost grease cleaning performance of liquid laundry detergents, especially under cold water washing conditions. Whiteness is also improved. The esteramine according to the present invention show improved compatibility in liquid laundry detergent formulations.
Abstract:
The present invention relates to a process for mineral oil extraction by means of Winsor type III microemulsion flooding, in which an aqueous surfactant formulation comprising at least three ionic surfactants which are different with regard to the alkyl moiety (R1)(R2)—CH—CH2— and are of the general formula (R1)(R2)—CH—CH2—O-(D)n-(B)m-(A)l-XYa−a/bMb+ is injected through injection boreholes into a mineral oil deposit, and crude oil is withdrawn from the deposit through production boreholes. The invention further relates to surfactant formulations of ionic surfactants of the general formula.
Abstract:
In a method of treating a substrate including patterns having line-space dimensions of 50 nm or below, the substrate is rinsed by an aqueous composition including at least one non-ionic surfactant A and at least one hydrophobizer B. The at least one surfactant A has an equilibrium surface tension of 10 mN/m to 35 mN/m, determined from a solution of the at least one surfactant A in water at the critical micelle concentration. The hydrophobizer B is selected so that the contact angle of water to the substrate is increased by contacting the substrate with a solution of the hydrophobizer B in water by 5-95° compared to the contact angle of water to the substrate before such contacting.
Abstract:
The present invention relates to a surfactant mixture comprising at least three ionic surfactants which differ in terms of the hydrocarbyl moiety (R1)(R2)—CH—CH2— and are of the general formula (I) where R1, R2, A0, k, X, o, Y, a, b, M are each as defined in the description and the claims. The invention further relates to the use and preparation thereof, and to aqueous surfactant formulations comprising the mixtures, and to processes for producing mineral oil by means of Winsor type III microemulsion flooding, in which the aqueous surfactant formulation is injected into a mineral oil deposit through injection wells and crude oil is withdrawn from the deposit through production wells.
Abstract:
Compositions and methods of synthesis of anionic surfactants by alkoxylation of a Guerbet alcohol (GA) having 12 to 36 carbon atoms using butylene oxide, and optionally propylene oxide and/or ethylene oxide followed by the incorporation of a terminal anionic group are described herein. The GA of the present invention is made by a facile and inexpensive method that involves high temperature base catalyzed dimerization of alcohols with 6 to 18 carbon atoms. The large hydrophobe ether surfactants of the present invention find uses in enhanced oil recovery (EOR) applications where it is used for solubilization and mobilization of oil and for environmental cleanup. Further, the hydrophobe alkoxylated GA without anionic terminal group can be used as an ultra-high molecular weight non-ionic surfactant.
