    摘要： Non-spherical siliceous particles having a plurality of porous branches are disclosed and claimed. The porous branches are randomly oriented and elongated, ring-like, and/or aggregated. An additive introduced during synthesis of the particles modifies pore volume and morphology. The tunability of the pore volume includes an inner diameter ranging from about 2 Å to about 50,000 Å. Synthesizing the particles includes mixing under constant or intermittent stirring in a reaction vessel an aqueous silicic acid solution with an acidic heel solution to form a mixture. The stirring may optionally be performed at a variable speed. An additive is introduced into the mixture at a controlled rate, wherein the additive imposes a pH change from a lower pH to a higher pH to the mixture to induce siliceous particle precipitation. Optionally, a metal dopand may be introduced into the particles and/or at least a portion of an outer surface located outside of the pores and/or an inner surface located inside of the pores may be modified.

    摘要： A method of treating one or more hair shafts, each hair shaft including a cuticle layer and a cortex enclosed in the cuticle layer is disclosed. The method comprises: selecting one or more polymers that can penetrate the hair shafts with a pore size of about 5 angstroms to about 5000 angstroms; and treating the hair shafts by applying an effective amount of a composition containing said polymers to said hair shafts.
