Instant gel preparation (I) comprises a mixture of dry substances, where the mixture exhibits a content of: (A) at least a gel former and/or at least a super absorbing polymer; and (B) at least a solid material (gasified particles), preparing an acoustic perceptible effect by contacting with moisture, which contains at least a gas enclosed in a solid envelope. Instant gel preparation (I) comprises a mixture of dry substances, where the mixture exhibits a content of: (A) at least a gel former and/or at least a super absorbing polymer; and (B) at least a solid material (gasified particles), preparing an acoustic perceptible effect by contacting with moisture, which contains at least a gas enclosed in a solid envelope, where the envelope is such that gas is released when the envelope is contacted with water or moisture and the material of the envelope is saccharide based materials and the gas included in the gasified particles is carbon dioxide, nitrogen and/or air and the pressure of the gas included in the particles is larger than the environmental pressure. Independent claims are also included for: (1) use of gasified particles comprising at least a gas enclosed in a solid envelope based on saccharide, where the envelope is such that the gas is released when the envelope is contacted with water or moisture, acoustic indicator to indicate that (I) can be readily used after liquid addition or to indicate the instant use of a preparation containing active- and auxiliary materials after addition of water or an aqueous solvent, where the active- or auxiliary materials present in micro capsule of non water-proof material; and (2) a method of preparing a thickened, readymade cosmetic agent comprising either preparing aqueous or water containing solvent system and adding (I); or adding aqueous or water containing solvent system to (I), agitating until the acoustic effects are terminated.
