Abstract: Methods for preparing high loading core shell silica (CSS) particles, or CSS particles having a relatively greater amount of surface active silicate groups than CSS particles prepared according to conventional methods is provided. The method may include contacting silica particles with a base having a first metal ion to produce core shell silica particles. Each of the core shell silica particles may include a silica core and a silicate of the first metal ion etched on a surface of the silica core. The method may also include contacting each of the core shell silica particles having the silicate of the first metal ion with an acidic aqueous solution including a metal salt having a second metal ion to produce core shell silica particles including the silica core and a silicate of the second metal ion on the surface of the silica core.

Abstract: An oral treatment device for dispensing an oral treatment composition onto a user's teeth. The oral treatment device may include a storage and delivery component and an applicator component. The storage and delivery component may include a body having a reservoir, a frangible capsule containing the oral treatment composition located in the reservoir, and a delivery member. The applicator component may include a pad portion formed of a liquid absorbing material. The applicator component may be alterable between an attached state whereby the delivery member is fluidly coupled to the pad portion and a detached state whereby the applicator component is detached from the storage and delivery component and can be placed into contact with the user's teeth. The frangible capsule may be in a sealed state until broken by a user at which point the oral treatment composition may flow into the pad portion of the applicator component.
