Abstract:
The present invention relates to the use of anionic gemini tensides of the formula (I), in which R and R are, mutually independently, a hydrocarbon radical with 1 to 22 carbon atoms, R is a spacer containing 0 to 100 alkoxy groups, and X and Y, mutually independently, are functional groups and the degree of substitution z = 1 to 10, in washing, cleaning and body care agents in which the proportion of said tensides amounts to at least 0.1 %.
Abstract:
Detergent compositions with high sudsing properties comprise an anionic surfactant of the alkyl sulfate, alkyl ethoxy sulfate, 2-sulfonated fatty acid methyl esters, alkyl benzene sulfonates, secondary alkyl or alkenyl sulfates, alkyl ethoxy carboxylates, sulfated or polyhydroxy fatty acid amides class, and a specially selected soap such as sodium 2-butyl-1-octanoate. The compositions provide spontaneous emulsification of grease even at neutral pH, especially in the presence of calcium ions. Sudsing may optionally be boosted by incorporating magnesium ions into the compositions. Laundry and dishwashing compositions are provided. Compositions containing a polyhydroxy fatty acid amide, sulfated polyhydroxy fatty acid amide, or alkyl ethoxy carboxylate are especially useful.
Abstract:
A detergent composition containing a mixture of linear alkybenzene sulfonate surfactant and mid-chain branched surfactant and an electrolyte is disclosed. The detergent composition includes a mid-chain branched primary alkyl sulfate surfactant and an electrolyte capable of increasing the ionic strength of the compositions resulting in improved performance, especially under low water temperature wash conditions. Typical electrolytes include sodium chloride, magnesium sulfate, calcium carbonate and the like.
Abstract:
Aqueous unbuilt liquid or gel-form detergent compositions are provided comprising, from 15 % to 65 % by weight of a core surfactant mixture, comprising from 5 % to 95 % by weight of the mixture of a water soluble anionic sulphate or sulphonate surfactant salt together and from 5 % to 95 % by weight of the mixture of one or more compounds of formula (I), wherein Z is a polyhydroxy hydrocarbyl moiety having a linear hydrocarbyl chain with at least three hydroxy groups connected directly to the chain, said moiety being derived from glucose and mixtures thereof with maltose, the maltose comprising not more than 33 % of the mixture, R is a C6-C16 hydrocarbyl radical and R1 is a C1-C4 alkyl or C2-C4 hydroxyalkyl group, a 0.12 % solution of the surfactant mixtures of the compositions having an interfacial tension (IFT) of less than 0.2 Pa.cm at 48 DEG C and a polypropylene cup (PPC) greasy soil removal value of at least 1.4 x that of the anionic surfactant component(s) alone. Preferred optional ingredients include amide, betaine and ethoxylated C9-C11 fatty alcohol suds modifiers.
Abstract:
The present invention relates to a colorant catcher material, comprising a) a substrate, b) a colorant-catching additive selected from the group consisting of polyvinylamines in form of homopolymers, copolymers and/or partial salts thereof, polyethylenimines in form of homopolymers, copolymers and/or partial salts thereof, and mixture thereof, which is fixed on the substrate by c) a fixing agent selected from the group consisting of dialdehydes with the carbon number of from 2 to 8, to a method for preparation thereof and use of the same for catching colorants or removing dirt in an aqueous medium, particularly a laundry washing solution.
Abstract:
The invention provides surfactant compounds of formulas I-IX, which can be used in methods for aiding the solubilization, digestion, preparation, analysis, and/or characterization of biological material, for example, proteins or cell membranes. The compounds can also aid in the recovery of peptides generated during protein digestion, particularly for in-gel digestion protocol. Additionally, the compounds can improve enzymatic protein deglycosylation without interfering with downstream sample preparation steps and mass spectrometric analysis. The compounds can be specifically useful as digestion aids that can be decomposed by an acid, by heat, or a combination thereof. Decomposition of the surfactants allows for facile separation from isolated samples, and/or allows for analysis of the sample without interfering with the sensitivity of various analytical techniques.

Abstract:
Mixed nonionic/anionic surfactants which comprise polyhydroxy fatty acid amides and their sulfated analogs are used with soaps in various cleaning functions. Thus, C10-C22 fatty acid N-alkyl glucamides are partly sulfated to form mixtures of the nonionic glucamide and the anionic glucamide sulfate. The resulting mixtures are admixed with soaps to provide extremely low interfacial tensions and good cleaning of fabrics, dishware, skin and hair. Excellent removal of cosmetic stains from fabrics is also provided.
