Abstract (en)
[origin: WO2014011456A1] The present invention relates to topical compositions containing solid particles that are stabilized via encapsulation into a cross-linked silicone matrix. The stabilized particles possess an electrical potential sufficient to prevent the particles from penetrating into the skin. The particles can readily be used either alone or in combination with other skin care actives to form topical compositions with improved stability and performance.
