Patent ID: 8193137

Claim:
A thickening composition, comprising: (A) at least one N-long-chain acyl glutamic acid and/or a salt thereof; (B) at least one amphipathic substance having an organic value and an inorganic value satisfying formula (1): (inorganic value)≦−5×(organic value)+2500 (1); (C) at least one inorganic salt; and (D) water, wherein the N-long-chain acyl glutamic acid and/or a salt thereof is the sole N-long-chain acyl amino acid and/or a salt thereof in the composition, the thickening composition has a viscosity of not less than 200 mPa·s, the weight ratio of (A) to (C) is 99:1 to 55:45, and the weight ratio to the total combined amount of (A), (B) and (C) to (D) ((A+B+C)/D) is 2.5:97.5 to 50:50.
