Abstract
An aqueous solid topical composition comprising a matrix, i.e., an aqueous solid matrix, having the appearance of a gel and possessing the following rheological profile:an initial viscosity at rest V0 sufficient to form a solid composition, preferably ranging from 50,000 to 1,000,000 Pa·s, said viscosity V0 being stable up to a shear strain C1,a viscosity V2 after shear at a strain C2 for which the ratio V0/V2 is greater than or equal to 1000:1,the difference C2-C1 being less than or equal to 1000 Pa,and which may be useful as a make-up, styling, body hygiene or care composition.
