Abstract

The present invention relates to a particulate highly porous amorphous mesoporous magnesium carbonate material suitable for uptake of high amounts of oily substances, sebum or a beneficial agent or combinations of these and to topical and cosmetic compositions comprising such material. The particulate highly porous amorphous mesoporous magnesium carbonate material according to the invention has a total pore volume larger than 0.1 cm 3/g and is constituted of particles having a peak particle size at or below 35 μm.

Abstract

The present invention relates to a sunscreen composition that comprises amorphous magnesium carbonate (MMC) mixed with at least one chemical UV filter in a range of 1-50 wt% of the amorphous MMC mixed with the at least one chemical filter. The amorphous MMC has a specific surface area (BET) of 100 m2/g up to 800 m2/g and a total pore volume larger than 0.1 cm3/g. The chemical UV filter is an organic compound absorbing UVB and/or UVA light.
