Gelmix Thickener Mixing Tips:
Advanced Preparation: Gelmix can be premixed with water, most infant formulas and many other liquids up to 24 hours in advance. Gelmix continues to gradually thicken liquids over time, so reducing concentration may be necessary for mixing batches in advance.
Mixing with Formula: The storage duration is dependent on the formula manufacturer’s instructions. Gelmix will not affect the storage duration of thickened formula. For powder formulas, just premix the warmed water and Gelmix, and store in the refrigerator or in a clean covered pitcher at room temperature until formula powder needs be added before feeding.
Note: We do not recommend mixing breast milk and Gelmix in advance. In order to activate Gelmix, the liquid has to be warmed, but breast milk should not be warmed twice. Breast milk mixed with Gelmix may be kept at room temperature for up to 3 hours.
