Claims
- 1. A surfactant composition comprising:
- a nonionic, anionic or amphoteric surfactant or a mixture of said surfactants and, as a viscosity-increasing agent therefor,
- a fatty acid-modified polyester which is the reaction product of the components comprising a dimerized fatty acid and a polyalkylene oxide, said fatty acid-modified polyester having the formula ##STR4## in which R is C.sub.8 -C.sub.22 -alkyl or C.sub.8 -C.sub.22 -alkenyl; R.sup.1 is the alkyl skeleton of a dimerized fatty acid having 22 to 42 carbon atoms; A is --C.sub.2 H.sub.4 -- or --C.sub.3 H.sub.6 --, n is a number from 1 to 5; and x is a number from 20 to 150.
- 2. A surfactant composition according to claim 1 comprising:
- about 0.1 to about 10% by weight, relative to the weight of the total composition, of a said fatty acid-modified polyester,
- an aqueous phase, in which said fatty acid-modified polyester has been dissolved to increase the viscosity of said phase, and
- said surfactant or mixture of surfactants dissolved, suspended or emulsified in the resulting viscous aqueous phase.
- 3. A surfactant composition according to claim 1 which is an essentially clear-appearing solution, suspension or emulsion.
- 4. A surfactant composition according to claim 1, wherein:
- R is C.sub.12 -C.sub.18 alkyl,
- n is a number from 1 to 3, and
- x is a number from 23 to 140.
- 5. A surfactant composition according to claim 4, wherein R.sup.1 is the alkyl skeleton of a dimerized fatty acid having 34 carbon atoms.
- 6. A surfactant composition according to claim 1 having a viscosity of at least about 850 mPa.multidot.s, measured at 20.degree. C. in an RVT Brookfield reaction viscometer.
- 7. A surfactant composition according to claim 1, wherein said composition contains an alkyl ether-sulfate or an alkane sulfonate as a said surfactant.
- 8. A surfactant composition according to claim 7, wherein said alkyl ethersulfate is a sodium alkyl ether-sulfate of the formula RO--CH.sub.2 CH.sub.2 O.sub.z --SO.sub.3 Na, wherein z is a number from 1 to 5 and R is C.sub.8 -C.sub.18 alkyl, or an acylamidoalkyl ether-sulfate or an alkyldiglycol ethersulfate.
- 9. A cleaning, cosmetic, or pharmaceutical composition comprising:
- a water-containing phase,
- a nonionic, anionic or amphoteric surfactant or a mixture of said surfactants dissolved, suspended or emulsified in said water-containing phase, and, as a viscosity-increasing agent therefor,
- a fatty acid-modified polyester which is the reaction product of the components comprising a dimerized fatty acid and a polyalkylene oxide, said fatty acid-modified polyester having the formula ##STR5## in which R is C.sub.8 -C.sub.22 -alkyl or C.sub.8 -C.sub.22 -alkenyl; R.sup.1 is the alkyl skeleton of a dimerized fatty acid having 22 to 42 carbon atoms; A is --C.sub.2 H.sub.4 -- or --C.sub.3 H.sub.6 --, n is a number from 1 to 5; and x is a number from 20 to 150,
- said fatty acid-modified polyester being dissolved in the water-containing phase.
