Ringing gel composition
The present invention relates to the field of liquid solubilizing systems. More specifically, the present invention relates to a ringing gel composition, one that is a self-thickened composition having a viscoelastic behavior and a viscosity comprised between 0.1 and 1000 Pa·s at 20° C. at 0.01 s −1 shear rate. The ringing gel has an aqueous phase, a surfactant system of one or more non-ionic surfactant(s), a linker and an oil phase that includes a hydrophobic active ingredient such as a perfume. Consumer products that contain the ringing gel composition, such as a self-thickened liquid laundry scent booster are also part of the present invention.
