Abstract
Aqueous surfactant compositions containing in each case one or more alpha-sulfo fatty acid disalt, a sulfoketone, a specific cationic polymer, a soap, an inorganic salt of sulfuric acid, and water are disclosed. The compositions have good foaming ability, a pleasant sensory feel to the foam, good skin compatibility, and are suitable for cosmetic products, detergents, and cleaning products.
Claims9
An aqueous surfactant composition comprising
- one or more alpha-sulfo fatty acid disalt (A) of general formula (I),
- R1CH(SO3M1)COOM2 (I),
- in which the radical R1 is a linear or branched alkyl or alkenyl radical having 6 to 18 carbon atoms and the radicals M1 and M2, independently of one another, are selected from the group consisting of H, Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine,
- one or more sulfoketone (B) selected from a compound (F) and a compound (G),
- in which compound (F) has general formula (VI)
- R6CH2—CO—CHR7(SO3M8) (VI),
- in which the radicals R6 and R7, independently of one another, are a linear or branched alkyl radical having 6 to 18 carbon atoms and the radical M8 is selected from the group consisting of H, Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine,
- and wherein the compound (G) has general formula (VII)
- (SO3M9)R8CH—CO—CHR9(SO3M10) (VII),
- in which the radicals R8 and R9, independently of one another, are a linear or branched alkyl radical having 6 to 18 carbon atoms and the radicals M9 and M10, independently of one another, are selected from the group consisting of H, Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine,
- one or more cationic polymer (X) selected from the group consisting of Polyquaternium-6, Polyquaternium-7, Polyquaternium-10, Polyquaternium-11, Polyquaternium-16, Polyquaternium-22, Polyquaternium-24, Polyquaternium-32, Polyquaternium-37, Polyquaternium-39, Polyquaternium-44, Polyquaternium-46, Polyquaternium-47, Polyquaternium-53, Polyquaternium-67, Polyquaternium-68, Polyquaternium-72, Polyquaternium-74, Polyacrylamidopropyltrimonium Chloride, Polymethacrylamidopropyltrimonium Chloride, Acrylamidopropyltrimonium Chloride/Acrylamide Copolymer, Guar Hydroxypropyltrimonium Chloride, Cassia Hydroxypropyltrimonium Chloride, and Starch Hydroxypropyltrimonium Chloride,
- one or more compound (C) of general formula (III)
- R4COOM5 (III),
- wherein the radical R4 is a linear or branched alkyl or alkenyl radical having 7 to 19 carbon atoms and the radical M5 is selected from the group consisting of H, Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine,
- one or more inorganic salt of sulfuric acid (D) of general formula (IV)
- (M6)2SO4 (IV),
- wherein M6 is selected from the group consisting of Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine,
- and water, wherein if the aqueous surfactant composition comprises one or more ester sulfonate (E) of general formula (V)
- R2CH(SO3M7)COOR3 (V),
- in which the radical R2 is a linear or branched alkyl or alkenyl radical having 6 to 18 carbon atoms and the radical R3 is a linear or branched alkyl or alkenyl radical having 1 to 20 carbon atoms, where the radical R3 can be an alkenyl radical or be branched only above 3 carbon atoms, and the radical M7 is selected from the group consisting of Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine, it is the case that the compound (A), based on the totality of the compounds (A) and (E), must be present to an extent of 50% by weight or more, and wherein the aqueous surfactant composition is free from anionic surfactants other than components (A), (B), (C), and (E).
