DIY: How to fix a broken powder & dispose nailpolishes correctly
Blogger ruined the quality of the picture but you can still see what's happening... So take your broken powder product (eyeshadow, bronzer, just anything in a powder form), crush it and keep adding small amounts of pure alcohol until you have a thick paste. Then spread it evenly, finish by flattening it with a sheet of toilet paper and let dry.
Just leave the cap open overnight! Then you can toss away the dried out bottle.
