Why does my Phillips Milk of Magnesia look different than usual (watery, gritty)?

If Phillips Milk of Magnesia freezes, it will have a watery and gritty appearance when thawed. For this reason, do not store it in your freezer or refrigerator. For best results, we do not recommend using the product if it has a watery appearance.

It is watery because you didn’t shake it. Shake it well, and it is going to be very creamy.
