Our Science

At Ceres Chill, we know that when you invent something new, it's more important than ever to have it rigorously tested and validated before putting it on the market. When that product is designed to keep breastmilk safe for newborns, it is absolutely of the highest importance to ensure that every product passes the most challenging tests.  All our breastfeeding products meet Consumer Protection standards for infants, FDA, and California Prop 65 guidelines.

We work with trusted manufacturing partners that are like family and Eurofins, the gold standard in consumer products testing, is our primary partner for product safety testing. We use the highest quality materials and we KNOW our products are safe for our babies and yours.

We also work with leaders in the field of breastmilk science to ensure we are providing families with the most cutting-edge research on the power of breastmilk and the safest storage.

How is Bismuth different than Lead?

To make sure that bottles like this (that are storing something as crucial as human milk!) are properly insulated, they need to be vacuum sealed. Optimal insulation is the seal at the bottom of the bottle where the air is removed. It often looks like a small circular disc in the middle of the bottle.

Traditionally, lead sealant was used to create this airtight seal, but concerns over lead content have led to safer alternatives.

While some brands continue using the lead material, we use Bismuth Oxide lead-free hermetic sealant glass. This innovative material ensures a secure and deep vacuum seal without the harmful effects associated with lead.
