Hello
The other day I got a mask from a soap maker locally. The ingredients were kaolin clay, zinc oxide and glycerin. She said there is no preservatives in the mask and mask shelf life is 6 months if kept in refrigerator.
Is it possible.? Should I use it for 6months or throw it of after one or 2weeks.??

Thanks.
 
Since there's no water in the formula and high percentages of glycerin is a preservative in itself (it's used a lot in medication manufacturing) there is no need to add any additional preservative, so the face mask should be perfectly fine to use for longer than 2 weeks. Just make sure not to get water into the container.
