Abstract:
The present invention relates to hand dishwashing detergent compositions containing modified alkylbenzene sulfonate surfactants (MABS). These MABS comprise a mixture of specif branched and non-branched alkylbenzene sulfonae compounds, which are further characterised by a 2/3-phenyl index of 275-10000.
Abstract:
A hand dishwashing composition comprising: i) from about 0.01 % to about 99.99 % by weight of composition of a surfactant mixture, said surfactant mixture comprising: an alkylarylsulfonate surfactant system comprising at least two alkylarylsulfonate surfactants of the formula (I) wherein L is an acyclic aliphatic hydrocarbyl of from 6 to 18 carbon atoms in total; M is a cation or cation mixture and q is the valence thereof; a and b are numbers selected such that said alkylarylsulfonate surfactant is electroneutral; R' is selected from H and C1 to C3 alkyl; R'' is selected from H and C1 to C3 alkyl; R''' is selected from H and C1 to C3 alkyl; both of R' and R'' are nonterminally attached to L and at least one of R' and R'' is C1 to C3 alkyl; and A is aryl; wherein said alkylarylsulfonate surfactant system comprises two or more isomers with respect to positions of attachment of R', R'' and A to L; in at least about 60 % of said alkylarylsulfonate surfactant system, A is attached to L in the position which is selected from positions alpha- and beta- to either of the two terminal carbon atoms of L; and wherein further said alkylarylsulfonate surfactant system has at least one of the following properties: said alkylarylsulfonate surfactant system has a ratio of nonquaternary to quaternary carbon atoms in L of at least about 5:1 by weight, when said quaternary carbon atoms are present; or percentage biodegradation, as measured by the modified SCAS test, that exceeds tetra propylene benzene sulphonate; ii) from about 0.0001 % to about 99.99 % by weight of composition of a conventional hand dishwashing adjunct; and iii) from about 0.01 % to about 7 % by weight of composition of a divalent ion selected from the group consisting of magnesium, calcium and mixtures thereof.
Abstract:
The invention relates to surface-active compositions. The inventive surface-active composition comprises a synthetic anion surface-active agent based on ethylene glycol ether sulphates of monoalkyl phenols having general formula R -C6H4O (C2H4O)m SO3X (1) or the composition of formula (1) with a composition of formula /C6H7O2(OH)2-z(OSO3X)(NH2)0.8-y (NHSO3X)y (NHCOCH3)0.2 /n (2), or the composition (1) with a composition of formula R O- (CH2C2O)kH (3), or the composition (1) with a composition of formula R C6H4 O (C2H4O)mH (4) or the composition (1) with compositions (2) and (4). R1 is an alkene radical, m is an average number of ethylene oxide molecules added to one alkylphenol molecule. Said surface-active composition also comprises X-gegenion and water. It is possible to obtain various combinations of the number of alkyl radical carbon atoms, of the average number of ethylene oxide molecules added to one alkylphenol molecule.
