Abstract: A foaming cleansing preparation and system that produce a high quality, self-sustaining foam immediately upon exposure to water without physical agitation or rubbing is provided. The inventive cleansing preparation is made up of at least one dry acid, at least one dry base, and at least one liquid film-forming cleansing agent. When the cleansing preparation is exposed to water, the acid(s) and the base(s) will react to form a gas and the cleansing agent(s) will form a liquid film, and the gas and the liquid film will then interact to form or generate a foam. The inventive cleansing system is made up of a plurality of delivery particles, with each such delivery particle containing one or more components of the inventive cleansing preparation.

Abstract: Organic prepolymer fillers capable of curing and reacting chemically with elastomers to form covalent bonds therewith are mixed with elastomers to form reinforcing domains with diameters of from 0.01 to about 50 microns, and when the mixture is cured, the mechanical strength of the elastomer is increased. In many cases, the thermal stability and/or the hydrolytic stability will also be increased.
