Claim 0:
1. A composition in the form of an oil-in-water emulsion comprising in a physiologically acceptable aqueous medium:
a) at least Baicalin and/or one of its derivatives or a plant extract containing it,
b) at least one superabsorbent polymer,
c) at least one homo- or copolymer of non-superabsorbent acrylic acid that is at least partially neutralized chosen from among sodium polyacrylates and potassium polyacrylates, and
d) at least one gemini surfactant with formula (III):, wherein:
R1 and R3 designate, independently of each other, an alkyl radical with 1 to 25 carbon atoms;
R2 designates a spacer comprised of a linear or branched alkylene chain with from 1 to 12 carbon atoms;

X and Y, independently of each other, designate a —(C2H4O)a—(C3H60)bZ group in which
Z designates a hydrogen atom or a —CH2-COOM, —SO3M, —P(O)(OM)2, —C2H4-SO3M, —C3H6-SO3M or —CH2(CHOH)4CH2OH radical, in which M represents H or an alkali ion or an alkali earth ion or ammonium or alkanolammonium,
a varies from 0 to 15,
x varies from 0 to 10; and
the sum of a+b varies from 1 to 25; and
n varies from 1 to 10,

said composition having a pH of 6.0 to 6.5,
wherein the superabsorbent polymer is present in a content of active material ranging from 0.1% to 0.6% by weight with respect to the total weight of the composition, and wherein the ratio by weight between the homo- or copolymer c) and the superabsorbent polymer b) is between 1.3 and 1.9.
