A dosing cap for use with or without a separate container for combining two different ingredients at time of use by dispensing ingredient one from the dosing cap into a container with ingredient two. The dosing cap includes a moisture and waterproof seal to prevent the ingredients from receiving any moisture during storage, an absorbent material (desiccant) included with the seal to absorb any residual moisture in the container or that might be received into the container during storage to ensure a moisture free environment for the ingredient and a tracking device such as a radio frequency identifying chip (RFID) that is attached to the dosing cap for product identification and tracking purposes.
