Patent ID: 7357922

Claim:
A microemulsion comprising: (A) 0.5 to 70% by weight of the alkanolammonium salts of alkylsulfates and alkylpolyalkyleneglycolethersulfates having the structure: R 1 —O—(C p H 2p O) m —SO 3 − HN + R 2 R 3 R 4 , wherein R 1 is a C 8 - to C 20 -hydrocarbon residue, p is an integer from 2 to 5, wherein p can be different for each m, R 2 is H, a C 1 - to C 6 -alkyl, or a C 2 - to C 4 -hydroxyalkyl, R 3 is H, a C 1 - to C 6 -alkyl, or a C 2 - to C 4 -hydroxyalkyl, R 4 is a hydroxyisopropyl, and m is an integer from 0 to 7, and mixtures thereof; (B) 20 to 95% by weight water; (C) 0.1 to 20% by weight of at least one oil component; and (D) 0.1 to 20% by weight of at least one mono- or polyvalent C 2 - to C 24 -alcohol, each based on the total composition of the microemulsion, said microemulsion being optically transparent.
